Hi all,
I've called T-Mobile 3 times now and am receiving an MM#6 error (phone not allowed) on my Gear S.
Any suggestions are welcome.
The device is Network unlocked
I just went through 2 hours of calls with Customer Service on this same issue. The S was an ATT unlocked watch that I wanted to add to my Tmo account. Never had any success, even after speaking with Tier 2 support. This is not unique to the S. If you do a google search you will find a variety of ATT unlocked devices having the same issue on Tmo.
One tech told me that it is something ATT writes into its code. Who Knows? I gave up and put the S on my Sister's ATT account and now it works fine. When I checked the ATT device unlock page, it does not recognize the IMEI of the watch. This is another problem other users have experienced.
having the same problem...
now feeling jipped... any fix?
Just to test, i used a h2o wireless 10$ pay as you go sim kit and phone and text works fine. Data does not.
But i only expect to use the phone and text for emergency only. ie.. running etc.
So, will keep mobile network switched off except when i need it.
10$ lasts 90 days.
i have my phone with me most of the time so its bluetooth tethered.
But for when i want to run, i dont fancy carrying my phone with me.. then i will switch the mobile network on.
Its a crutch, but its real cheap. cheaper than any monthly plan, considering that i wont be using the mobile network phone/text very often at all. just good to know its there.
Att gear s on tmobile mm#6 error fix
I have an at&t gear s unlocked working flawless on tmobile 5dollar wearable plan 4g working its very simple to do by dialing *#2263# on your watch and then press wcdma after that scroll down to wcdma all after that swipe down and restart your watch. Everyone's problem is that they asume tmobile watch is running on gsm and guess what its not thats there little secret on the wearables thats why your all getting mm#6 error its clashing
Wished that would have worked for me, but no joy.

Howdy, y'all!
I was looking at a good deal locally to get an LG V60 UW 5G, but I'm on T-mobile. I was wondering if I could get it working for T-mobile's 5G bands (71, 66, 2, etc); or if there would be some issues as it's a Verizon phone originally (that's unlocked). From what I can tell is that it should work as it does have the correct bands. Any help or further info would be greatly appreciated!
Thanks,
Loubar
5G may not work. I think the Verizon version of 5G uses an mm wave radio that is different from T-Mobile.
Best of luck to you though.

It doesn't work
Don't try this as I am currently stuck in this situation. I thought it would work so I bought a Verizon LG v60 and connected to T-Mobile network. Now I only have 4G and it drops to 3G to make phone calls. ? The only hope is for T-Mobile to go mm wave soon.
I have a Verizon LG-V60 UW on T-Mobile and it worked perfect on 5G in the Missouri area. I'm almost in Arkansas and I'm still getting 5-G. It used to do the shuffle where it would go from 5G down to 3G or HSPA when I would make a call which means I wasn't getting VOLTE because if I were, then it would not need to drop to 3G or anything less than 4G LTE to make phone calls. I could be wrong, but I think it's a slim chance, I suspect the deficiency is not with the hardware, i.e., the Verizon model has enough bands to support VOLTE even on T-Mobile's Sprint-T-Mobile combination of towers, (hence the ability to receive consistent 5G) but Verizon has found a way to defy the deal they signed onto when the FCC let them come in before the doors were open to bid on spectrum privately and Verizon promised to make phones that were SIM unlocked for...ever. They have been bucking that clause in the agreement ever since, but of lately they are REALLY pushing back at the FCC by locking SIMs, and the FCC has capitulated a few times IMHO by allowing Verizon to lock them under certain circumstances such as if a device is not paid off or not on their network long enough- which begs the question, what did they get from Verizon that's any different from the rest of the carriers? That is the industry standard, but I digress. Point is they want to tether their phones to their network and they have started to decide some more thoughtful ways as opposed to just defying the FCC outright by locking the SIMs, and one of them is to deny WIFI calling if you are not on their network with the V60 at least. You are directed every time the phone powers up to put in your address for 911 purposes since WIFI calling doesn't always transmit the address to the police like the E911 would on a cellular call. This is NOT a requirement, by the way, there is no law that says you can't make phone calls over wifi without appraising the police as to where to send the cops if you ever dial 911 over WiFi. But, there is no way around Verizon's interface on the LG-V60, and, as you can guess from my rant, you will never be able to successfully update your address with Verizon if you are on TMobile, or anybody else that I've seen because it will just bounce around for a few minutes of pointless waiting to come back and tell you that something went wrong and you can try again... But don't. There isn't any purpose and they know it. You won't be able to update Verizon's databases from another carrier unless maybe you still have an account with Verizon, and that's still debatable from another carrier. So no WiFi calling on other networks. Ever. Same thing goes for VoLTE. It never provisions if you are on T-Mobile. Can't, Verizon has locked the door. It did work when I first got the phone. Then, I reset the phone and since I did not have initial access to Verizon's network, it did not provision (unlock the VoLTE). Unfortunate for me, I bought my device from the internet swap site and I checked the company's IMEI checker which green-lighted the sale by giving me the false impression that the device had no blacklists for theft or financial non-payment. Then, when I tried to circumvent the new way to prevent their Verizon customers from escaping by putting in my girlfriend's Verizon SIM in long enough to provision all the barriers aforementioned, and it locked her SIM up simply because the guy sold me a phone and Verizon told me that they can say that the IMEI is good quite a while after a person sells an unpaid phone before changing their report that the phone is clear and free to it is black listed, meaning that it is almost pointless to rely on their IMEI check because anyone can sell the phone while they owe a thousand dollars on it still and then, after you give them $900, they simply quit paying and you have all the problems of a blacklisted phone even though you were told it was a-ok when you checked with them and ran the IMEI before buying the phone. It was hell trying to get my girlfriend's phone working again after they unceremoniously shut it down for punishment of putting her Verizon SIM into a Verizon phone that someone had stopped making the payments. It wasn't stolen mind you; do not put your SIM in anybody's phone if you have a Verizon SIM because they won't tell you that it offends them, they just **** your service off and now you have to contact them and if it's on s holiday weekend like it was for me, you are screwed for a couple days. I was, and I was lost- no gps and running out of gas in the middle of nowhere. Long explanation, but it could be critical if someone owns a Verizon phone or attempts to buy one and puts their SIM in it to see if it works- God can't help you if you do.
Jeesh, all that and I forgot to mention this: I now use the 5G on CDMA, but cannot make calls. I just switch the mobile network to CDMA LTE and instantly I have 5G service but only emergency calls because VoLTE is not working. Nor video calling. But when I want to make a cellular call or see my text messages I switch back to Global mode and it goes right to 3G or HSPA (most time it flips constantly between the two over and over and over) and I get my texts and am able to make non-emergency calls. It's a hassle, but what am I going to do? Verizon is the biggest bully on the block, not even the FCC can push them around, and LG bit the bullet as far as phones are concerned. SMH...
I purchased a Verizon V60 (LM-V600VM) on ebay in late December 2021 and was told by Verizon customer service this phone's IMEI will not work on Verizon's network (likely due to original account holder's non-payment fulfillment, but that private info I'm not allowed to know). I never planned to us this V60 on Verizon's network and was 99% sure it would work on both T-mobile and AT&Ts network even though it's blacklisted on Verizon's network. Well it does work on both T-mobile and AT&T networks (on Consumer Cellular plans) until just a few days ago. It now will no longer allow incoming or outgoing calls. It still does get 4GLTE data and receives/sends text messages (with photo's too). I turned on all settings I could think of but with no luck getting calls to work. I suspect calls are no longer working due to the 3G phase out requirements by the FCC to retire this frequently to make room for 5G. I also think this Verizon V60 phone does not have built-in VoLTE capability but instead uses Verizon's built-in HD voice (as a voice over network) technology to place calls when 3G is not available and used only on the Verizon network. Since this V60 is blacklisted and can never be used on Verizon's network and it looks like the 3G frequency has been retired (dropped off the face of the earth never to be resurrected again), I'm asking if anyone knows a way around my problem with not being able to place cellular calls now. I know about Google voice but that seems like a clunky patch alternative. Does anyone know if an AT&T or T-MOBILE V60 main board (motherboard) swap into a LM-V600VM Verizon phone would work in this situation???

Can you confirm if your Verizon LG-V60 UW is still able to make and receive calls while on T-mobiles network? My Verizon LG-V60 UW for some reason can not make calls now (on AT&T network). It use to without any problems about a couple of weeks ago. It now only gets 4GLTE data and receives/sends text, but calls can't go thru anymore

That's because the V60 doesn't support VoLTE anymore if you use a version of the phone not from your carrier, even then it might not work. If you use an LG v60 T-Mobile version on T-Mobile it might work, but I would count on it.
Pls LG v60 uw has; 2, 25, 41, 66, 71 SA/NSA/Sub6?
Is LG v60 uw has only 5g 260 and 261 mmwave?

I have an LG V60 from Verizon it worked awesome I got it when it first came out it always read 5G UW constantly never even saw 4G I lost that phone it got replaced and that phone worked perfectly fine as well now all of a sudden that phone got ran over and I'm on another replacement phone and it only reads 4G and it won't update my phone to Android 11 they told me something's wrong with my phone and I need to have the insurance company issue me another phone so the insurance company told me we can't send you another phone Verizon does not authorize replacement phones for Network signal or software issues. I talked to several texts from Verizon they had me reset the phone plug it into my laptop try to update the software that way none of it works it's stuck on Android 10 and they won't help me at all. And finally they telling me well your phone's going to search for the best signal it can get from the tires and that's all they can tell me so basically they're telling me it's getting the best signal it can which is only 4G I've had this LG V60 replacement phone for 6 months now and it hasn't read 5G once I'm so angry it sound real now I literally have to buy another one and make sure 5G UW works and make sure it can upgrade to 11 Android. Right now I don't know what to do other than at some point to buy another LG V60 it's the most unfair issue I've ever had with a smartphone device and Verizon is like the evil empire of carriers if you're not a business or corporate and y'all just a single person with an account take a care less in fact all they ever do is send me emails and texts to upgrade to a new phone so they can get more monthly payments out of me. I forgot to mention I bought the LG V60 when it first came out and I paid for it fully in cash. I swear because I'm not making phone payments did not quick to help at all
(US ATT and T-Mobile)
I have this phone, but only by way of ATT telling me my non-VoLTE 4G LTE phone would not work after ATT shuts down 3G.
I move over to T-mobile recently. All works ok. I then activate VoLTE on the Mi. All works ok.
But I had to call a T-mobile rep regarding my iPhone, in that conversation I asked if VoLTE was even needed, and he tells me no, that T-mobile will still do voice data w/o VoLTE enabled.
So, VoLTE is a feature of LTE and implemented on 4G/5G, and really has nothing to do with 3G being shut down.
There's so many sites stating you "need" VoLTE to keep making voice calls after 3G is gone. This is not true.
"As 3G is switched off, you need VoLTE or HD Voice support to make calls on 4G networks."

As I understand it you need 3G for voice.
You may be able to use internet service but without VoLTE, no phone service.
If the device is not white listed it likely will not be able to have phone service as your link states.
I have straight talk with AT&T sim, I was using my Black Shark 3 pro which has volte and all of a sudden Friday at midnight, no data or phone service. At that time my bs3pro has been having heating issues, so i moved everything over to my redmagic 6 which has volte. I noticed my sim was locked in apn, totally different apn info than my bs3pro, so i called support, since everytime I tried to make call it blocked calls and sent me to support. The CS person did something on their end, had me restart phone, then service was back to normal and been fine since.
If your service provider only provides 4G infrastructure like mine... then you need VoLTE otherwise no phone calls. They are new and never had any 3G and below infrastructure. I tried making calls .... it doesn't.
My service provider annoyingly doesn't provision volte for my volte capable handphone (this makes my eyes swivel) but does provide an app to support phone calls without volte.. but it chews up battery
@roger_rex
But T-mobile (US) runs 4G and 5G, but # of towers with 5G not as plentiful as 4G. I connect 4G LTE most of the time, voice & data works just fine. T-mobile rep told me it will work w/ or w/o VoLTE enabled on phone. The APN used is the "fast" APN one.
A 5G connection does not negate any benefits from using VoLTE.
Was on phone again today with a T-mobile "tech team supervisor" for a service issue (they accidentally turned off one of my SIM cards). I then asked about VoLTE, he tells me it's no longer needed on T-mobile 4G or 5G LTE, but using VoLTE will still work. He seemed to suggest VoLTE not needed at all on 5G because the speed of the wireless can carry both voice and data fast enough. He also hinted their 4G can do the same.
If you have a fast pipe then you really don't need a side channel for the voice.
But duly noted, everything technical that I have read about on VoLTE, using that feature gives better voice call on any LTE that supports VoLTE. The supervisor also mentioned that "VoLTE" will basically go away at some point.
Pretty sure on 4G LTE you need either VoLTE capability or a 3G connection for voice calls.
Redirect Notice
4G VoLTE will likely be here for a long time as 5G is distance/obstacle limited, the former is very hard to overcome due to the wavelength's physical properties.
@blackhawk
I am not disputing how online info says it's required, I am just copying what T-mobile has told me.
T-mobile store rep tells me VoLTE is not really needed, then their online support supervisor tells me the same thing. So it is for sure confusing.
Call a T-mobile support # and ask.
Why would a 3G/4G-LTE phone have an option to turn off VoLTE?

I never paid much attention to this and still have questions but it's back burnered for when I run across it. From what I'm reading the T-mobile reps sound like they don't understand it either.
Even if they don't understand it... the only thing that matters immediately is if it will work. Hopefully that intel is correct!
Really until AT&T implements the change I won't be 100% sure. However pretty sure I'm ok as the devices don't use the 3G band and in hidden user settings VoLTE is toggled on. The only indication other than the 4G that VoLTE is active.
Probably HD too, but no indicator or setting other than very good call quality.
To make matters even more confusing AT&T changed the format and models listed drastically 2 weeks ago from their December whitelist. So small wonder reps might be confused too. Makes you wonder if it was deliberately self serving, an oversight or ongoing system modifications?
So, I have not been paying close enough attention to cellular these days. The cell companies have amassed large sets of licensed bands, probably near 200+ bands between 2G/3G/4G LTE and 5G NR.
Interestingly enough, 5G is not LTE at all. I suspect operators call their crud "5G LTE" to signify they support 5G-NSA or 5G-NR (or both), and, the older 4G LTE.
Some airlines are worried about two cell C bands (n77 and n79) that back up onto aircraft radio altimeter that run 4200-4400Mhz.
VoLTE has a long history, but it seems 5G-NR does not even use VoLTE (because VoLTE is a LTE feature, and 5G is not LTE). Can a 4G/5G phone still use VoLTE? Sure, if the firmware is implemented to use it. Likely will use it if the device connects 4G LTE, but perhaps will not when connected to 5G-NR. It's not clear to me if a device will use both 4G LTE and 5G-NR at the same time, but I suspect not. I mean, you could technically connect a device on 5G-NR for data, and then use VoLTE on 4G LTE for facilitating voice calls.

My understanding on this is that voice was using some 3G or below service. My provider was purely 4G and above - so unless my phone was provisioned by the cell company - no voice calls. I tried & it didn't work. I changed to an older device that they did support via VoLTE and calls worked. I can download an App from the cell company that allows my pixel 2XL to work on their system.
I can only guess T-mobile has 3G and below network infrastructure still. My provider is brand new and never built any 3G stuff and have no intention of rolling out obsolete stuff. VoLTE is annoying in that the provider gets to pick and choose which cellphones they allow (to use a standard protocol)
This may not be 100% - I've been kind of forced into a crash course on this myself over the last few days

forum.xda-developers.com
Pixel 2's all have ability for VoLTE.
A cell operator should not be blocking any phone from using VoLTE.
When you call your provider what do they tell you when you tell them your Pixel 2 has VoLTE for 4GLTE but your Pixel won't make calls on their network?
I can tell you for sure, the operators play games with their support of hardware.
My iphone XS was connecting to ATT with a "5G" icon from time to time, so why does T-mobile say 5G is a "no"? I moved the XS to T-mobile and the phone won't ever connect to 5G, and the APN settings appear to be blocked.

Update: I find many sites that say the Xr and Xs do not support 5G, so now I scratch my head, my Xs would sometimes show "5G" icon for cell wireless, when it was on ATT network. Apparently AT&T supports Xs and 5G, hence the Xs does have 5G capable radio.

I think they go at least partially by number of a given model in use. My guess is it's not a painless procedure for them to configure their system for a given model.
AT&T first listed their Note 10+ variant but not the unlocked variant, a month later it was added as well. It may be a work in progress... it seems sort of helter skelter, oh my gawd get it done, whatever it takes... kind of deal
You know they are catching Berlin air raid volume flack
Before buying Mi 11 Lite 5G I went into a T-mobile store (not an affiliate). I asked if the Mi 11 Lite 5G will work on T-mobile and the rep told me all phones work on T-mobile as long as they are not locked to another carrier, and, the T-mobile freq bands ("channels") are covered by the phone.
Unless LTE or 5G-NR/5G-NSA is improperly implemented on the device, then I don't see why all phones should not work. They should all work.
Think about hotspot. The carrier can control is the device can use that service, or at least can with some devices, but why bother, who cares how the data on the data plan gets chewed up. Go over the plan and get charged. Thus far I have not seen unlimited hotspot data, T-mobile only allows 40G on their Magenta Max plan.
Good thing is, Mi 11 Lite 5G phone (model M2101K9G) works a-ok on T-Mobile USA. I did have to manually set the APN to the "fast" one, and had to use dial code for VoLTE, 4GLTE and 5G works.
Straight talk now keeps shutting off my service every 3 days, last night again, so 3 times now. Call and back working. But seems like they only care about giving me some crappy free phone and seems like they outsource. The redmagic 6 is not on AT&T list, if any more issues I will switch to T Mobile, T Mobile recognized my phone by imei and said it is fully compatible. I Noticed on my Redmagic 6, sim 1 is only 14 digits but sim 2 is 15, so I moved sim card, might be issue, but doubt it.
@Rotwiler I see you posted about the IMEI digit thing in another post/forum. *#06# should reveal a 15 digit IMEI. If it shows only 14 then the phone is hiding one digit. Put sim card in sim slot that has the 15 digit IMEI.
What does *#*#4636#*#* get you? Do some gooling around for activating VoLTE on RedMagic 6
Phone lists for carriers are mostly for support reasons. If the phone has all the cell bands the operator uses, then it should be good to go. If the phone only has some of the cell bands used, then the phone may work ok in one area, but not good in another, all depends on how the operator runs the bands in different areas. The cell operator does not want the support headache for a phone that only has partial bands, "hey ATT, my phone not working in Timbuck-too", etc.
The RM6 appears to have most of the ATT 4GLTE bands (all the major ones), so it should work a-ok on ATT (US). 5G should also work. It appears the RM6 had a firmware update about 26d ago. Make sure the firmware is updated to latest.
Are your APN settings correct?

I am using AT&T through Straight Talk. I did move sim card to slot 2 to see if issue was due to sim one showing only 14 digits. Phone is fully updated. Odd thing is I cannot change the APN since this new Volte, there is red check mark and everything is grayed out. I have always been able to modify APN until now. My sim card is really old, used to be full size and over the years cut it down for new phones, is probably 8+ years old, had it since Android phones came out, but has always worked great.

APN settings are grayed out when the phone is locked to carrier. Can you at least see what the APN settings are? If the phone is owned outright by you then tell the Straight Talk folks you want the phone unlocked.
As for old sim card, then just go get a new one from the store for a few $, and then move your number to the new sim card via online.
Phone is Redmagic 6 global version, never was locked.
Hi all,
Today, my battery level was only 20%, the phone suggest activate economy mode.
I made this when i was at work i start a full charge.
During charge and after, all work Wifi, internet but no phone call possible.
I see logo for network reception and 4G.
After full reboot, call work again ... But not secure because you see 4G logo and then you think full work but not.
Nobody with the same thing ?
Since this behaviour, i'm not sure at 100% that my phone work for calls and i've a little doubt in my mind ...

Not seen this issue; normal calls and wifi calling both working well; but then I'm in the UK on BT/EE; I hear some of the US network bands don't work so well with the phone?
Once fail again this evening ... I was on Telegram with my wife and we are speaking with text but she said now i try to call you but it's your voice mail.
On my Find N, i've logo 4G and level max for reception ... Then il try to call my wife but don't work for call.
After reboot phone, same issue and don't work ... and few minutes later, it's work i receipt voice call and i can call.
What's happening ? I'm so sad with this ... It's as dream phone but i've doubt for receipt and make voice call. Help me please. :-(

Sorry to hear that. Only thing I can suggest is to try a different network provider (as the problem sounds network related?), turn on WiFi calling if at home, or actually call via Telegram (effectively over 4G using mobile internet), or WhatsApp.
i am in the US ATT same thing happened to me would be able tog et text and use internet in 4g but ransomly would not get or be able to place calls. Its a great phone but could not risk not receiving calls.
If you're using ATT, your phone is about to become a lemon. When you make or receive a call, it uses a 3G network. ATT is shutting down their 3G towers this month so your area has probably shut down by now. Switch to Tmobile, it uses voice calls differently so you won't be having an issue.
I'm from Belgium and my provider is Mobile Vikings.
Mobile Vikings use the network from Proximus (most big provider in Belgium).
It's random, i'm afraid with this ...
I love very very very much this phone but i need to solve this :-(
After to speak with my local provider, confirmation that my phone full work and compatible with Mobile Vikings.
Mobile Vikings is in transition for to full pass to Proximus and then they give me a procedure for reboot and make some specific settings.
I try few days and comeback here for give you news and débrief.
Hello!
Can someone please help me with this?
Everything was fine until 2-3 days ago. When all of a sudden I was unable to send text messages or make phone calls. All the while I could access internet without any issues.
If I switch to 2G or EDGE for the Subnetwork, I can make calls and send SMS.
How can I fix this?
Could dropping the phone have caused this?
Dropping could certainly break something, of course, but let's assume that's not it.
What carrier? Is the phone officially supported by them (ie, IMEI matches the carrier)? Are you on their official ROM? Does/did your VOLTE work (before and after the "few days ago")?
Some carriers are switching over to VOLTE-only setups, so they may be testing that to see what works/doesn't before they make it final. In other words, maybe your phone is not "officially" supported by VOLTE on the carrier, which is why it's failing? Without VOLTE, I think text may fail as well (even if you're not actively on a call?)
That would be my first guess. In my case, for example, I was on a US998 phone (per IMEI) running VS996 on Verizon. Since the IMEI didn't match a VZ phone, they refused to say it was compatible (even though it worked fine for many years). The IMEI stuff is a bunch of BS, but that's a whole separate topic... but I wonder if this is what you're running into. It's the carrier's way to force you into "their" device, even though it's not any different from any other variant (when the proper ROM is installed).

Carrier texts should theoretically still work as they are "data". It's the "voice" part of VoLTE that won't work. That's why I can still receive carrier texts on my Galaxy Note 9 with AT&T -- which still has older firmware (so I can be rooted). A few months ago, I lost the ability to make/receive phone calls on my AT&T number when 3G towers were decommissioned in my area... But luckily I have Google Voice number, which also uses "data" (VoIP) so I make/receive all my Google Voice phone calls. (That's been my main phone number for years.)
However, I no longer can make/receive AT&T phone number calls -- which is fine. I switched Google Voice settings to data/Wi-Fi only instead of piggy backing on carrier phone number. Yet, I still receive AT&T texts, which is good because my bank insists on using a "real" (carrier) phone number for SMS security code confirmation.

I'm with a company that uses T-Mobile towers. I connect just fine with 4G LTE, and get reasonably good speeds over it. But when I'm on 4G, I cannot make or receive calls or text. It says Emergency Calls Only.
So far, I've tried everything. I resettled network. I looked for different APN values that may fix the issue. When I couldn't think of anything else, I did a factory reset. (I mean, I wiped Data, and all other partitions in TWRP except for System and SD Card.) There have been no changes.
I'm starting to think the issue may be hardware, I did drop the phone a couple of times the day it stopped working. Though I usually end up dropping the phone once a day or every two days. I can't believe the screen hasn't cracked yet, at all. Could a drop from 3-4 feet on hard surface like tiles damage the antenna in such a way that only 4G data works?
I'm ready to give up and buy a new phone even though I can't really afford it. It would be awesome if I can get this to work.

I'm on T-Mobile towers with the US998. I don't think there is an issue with IMEI. How would I connect to data with 4G if that was the case?
I never had Volte on this phone. I do recall seeing it when I first got it but I'm running stock rooted Android 9.
When I say it used to work a few days ago, I mean it just stopped working at one point. I wanted to make a phone call, and all of a sudden, I couldn't. I noticed then that it says Emergency Only sign, so I walked around the house for about 15 mins to try to get signal. Then I went to my car and drove around, but nothing.
I messed around with Network settings, and figured out that Voice and TXT worked when I switch to a lower 'Sub-Network' setting that says, "GSM / GSPR / EDGE Only".
To get 4G Data back, I have to switch it back to "LTE/Legacy 3GPP multi"
These two are found under "GSM/UMTS Settings", after clicking on "System Select" in "Mobile Networks ".
I want to also mention that my carrier website has been talking about a data migration that would affect phones using their old SIM Card.
When I saw that, I called them and had them send me a new SIM. I thought surely this must be it, but the new SIM works exactly like the old one.
Perhaps the migration or whatever it is they did that required new SIM cards just doesn't work well with my phone? Even though, before putting the order in, the rep I spoke to did check my IMEI and said that my phone is compatible.
Agreed, it doesn't sound like an IMEI issue.
FWIW, I showed a 4G connection on a phone (I don't remember if it was my V30 or a Galaxy S10+ that I was going to replace it with). On that phone, at one point, but there was no actual connection. So, the indicators aren't always accurate. That's why I thought maybe the data isn't really working, and if data isn't working then VOLTE won't work... and with many of the carriers switching off non-VOLTE calling, that could kill the ability to make calls?
In your case, you said data worked... but if VOLTE was never enabled, and the carrier dropped non-VOLTE, then, again, you may lose calling.
In any case, these were my theories. I think you're on top of the situation but I don't have any other ideas for you to try...
Instead of buying a new phone, have you considered installing and setting up Google Voice, as ChazzMatt said? I recently had to do that because AT&T's 3G shutdown meant that I could no longer place or receive calls. My quick guide on doing that is here: https://forum.xda-developers.com/t/...-based-custom-roms-when.4138223/post-87342453
I don't know why you can't also send or receive texts, but the Google Voice app has the ability to do that, so maybe try using that after you've set it up.

There's been reports T-Mobile which is now merged with Sprint has borked the ability for VoLTE/VoWiFi calling on US998 firmware phones (native or Frankenstein'ed). Apparently they only allow it now on T-Mobile H932, whereas pre merger they were happy to give VoLTE and voWi-Fi calling to "US998" phones
First, it was reported with new SIM cards they were distributing earlier this year. Then people who kept their old SIM cards found they didn't work after a forced "security update."
This seems to have also trickled down to the T-Mobile MVNOs.
This is why we told someone else recently they should probably convert their phone from US998 on T-Mobile to Verizon VS996 firmware.
Then get a Verizon sim card or Verizon MVNO SIM card, and activate it in an old cracked screen Verizon phone off eBay, then put that already-activated SIM card into their "VS996" V30.
They will have VoLTE and VoWi-Fi calling.
Alternatively, if you really want to stick with T-Mobile network, you can do what @osprey00 suggested -- which is get a Google Voice number and use it as a tool to forward your carrier calls to it.
You can read his post, see his experiences, and see if this would apply to you.
For ME -- I've been using Google Voice for the past 10 years as my main phone number. I ported my carrier phone number at the time to Google Voice. Then got throwaway carrier numbers (whoever had cheapest plan) but never gave those to my friends. To my friends nothing ever changed. I've had the same "number" for the past two decades.
But within the past couple years, I had to start giving my bank and my cable company my carrier phone number for SMS security codes. Very annoying, because in the past they used my Google Voice number to text me with no problem.
So, even though under my current firmware (on my rooted Note 9) I cannot get carrier phone calls, I still have LTE data. And with the LTE data, I can use Google Voice (calls and texts) because it's VoIP. I also get AT&t carrier texts, as that is also data. It's just AT&T phone calls I cannot send or receive.
AT&T deactivated the SIM card in my native US998 V30+ and sent me a replacement phone, which is a Samsung Note 9. I'm staying with AT&T for a reason. Otherwise I would probably pull the "V30" Verizon trick also.
I bought both my wife and my elderly mother 64GB V35 phones -- which is basically an upgraded 64GB V30. (They previously had native US998 V30.) AT&T gives V35 VoLTE and WiFi calling, and for them there was nothing new to learn.

I think it was a hardware problem, honestly.
No matter what I did, I even tried different ROM to ensure I didn't mess around with root settings and somehow enabled or disabled something that I should not have. I tried flashing stock radios, and no, nothing would fix it.
I took my brothers phone to see if the SIM card would work with his phone, an unlocked Google FI phone. As soon as I installed the SIM, and booted up the phone, I could tell it was working perfectly even on the lock screen. Right away the status showed the name of the wireless company, and active 5G data icon on the status.
I must have damaged the internal radio or the LTE data modem when I dropped the phone last. The screen of the phone never broke even though I dropped the phone countless times, though the back glass has cracked lines all over even if the surface is still smooth and the phone continued being waterproof (I tested).
Anyway, I have since bought a new phone and the Data/Text/Talk all work perfectly on it.
I'm not sure what I'll do with this phone, as selling it wouldn't be ethical. And I doubt anyone would buy a phone with the warning that service may not work.
Ah well, I may just keep and use it as a test device.
Thanks to all who tried to help.

tried a rom on a j7 2015 because android 6 is going to be left and I only get emergency calls on lte and on 3g, no problem. It's not imei problem maybe exynos processor. I went back to 6.0.1 and no problem with 4g lite. By the way, I'm not in the USA.
