In the G4 forum, we realized that Verizon has put some sort of firmware on the device that disables 4G LTE in GSM mode using a T-Mobile (or AT&T for that matter) SIM card, even though the phone does support the bands. When the phone is switched to CDMA mode, then 4G LTE works fine, but unfortunately voice doesn't work at the same time. See this thread here for more details: http://forum.xda-developers.com/verizon-g4/help/lg-g4-vs986-t-mobile-lte-problem-t3195888
Can anybody try out the same with the V10 and report back? Would be intersting to know if Verizon now intentionally started crippling these devices (since it used to work fine on the G3), or this is some sort of bug that only applies to the G4 right now. Thanks!!
I use a VZW branded V10 with my tmo sim and can only get H or H+. Rarely does it get 4gLTE. And when it does sms does not work.
Thanks... but you do get 4G LTE sometimes when in GSM mode?!?
Can you change the system mode in the mobile settings to CDMA and check if it gets 4G LTE with the T-Mobile SIM card? And then in the same place switch it back to GSM and see if it falls back to H+ only? That's the behavior we saw on the G4, like Verizon is intentionally blocking LTE om GSM, even though the phone supports the band.

I am not sure if it is the same with Tmobile, but when trying to use a Tmobile variant on AT&T, LTE does not work either. It seems that you have to get the device provisioned by the carrier for LTE using it's IMEI, not just doing a SIM swap.

Yeah if i switch to CDMA, i get 4G LTE very often though i cannot send message or call
Can anyone tell me if u get the annoying unauthorized sim card message... if so can we stop it from appearing. Had that issue with my verizon htc m8.
I tried at a T-Mobile store earlier to see if one of their Sim cards would work in my VZW V10 and I had the same issues.
The pop up saying "not a Verizon Sim" or whatever came up after a few minutes of dismissing it as well.
When it first loaded up, I changed the APN to match the in-store display V10 with its exact settings. I changed the network mode from global to LTE/GSM and after a minute it showed it was connected with 4G LTE, but it went away after a few seconds. I couldn't get it to come back, and it only had like 2-3 bars, and H for data. I know it wasn't from lack of signal because the display V10 had full bars with LTE.
I also tried sending a text using the T-Mobile SIM to one of my other numbers, but it didn't go through at all. Didn't try placing a call, but regardless it didn't seem like it would be worth it to switch.
No 4g LTE
Still waiting for a fix,can get no 4g LTE on t mobile,I'm on marsmallow so I lost root access
I'm Canadian, I just bought an unlocked Verizon V10 on ebay and I'm planning to use it on a Canadian carrier. Does this mean I should expect to have no LTE data at all on this phone in Canada? Poops I never would have bought it if that was the case.
Let me know, I may try a return without opening the package.
how different is the speed between HSPA+ and LTE? is it noticeable
does it bother you that its not LTE?
I bought a phone from a seller on swappa. when he listed it. the phone had a clean ESN.
took it to the verizon store to setup verizon prepaid and it was flagged a non pay account
cannot activate.
I am using my ATT sim card right now
I can return it but on the secondary market is many LGV10 phones are going to be flagged for non payment when the accounts go into collections, it then buyers could get screwed.
I might just stick with the phone. But i can never use it on verizon. I have to wait for a Root on marshmallow, and fix after that if I want LTE speeds on ATT or TMO
I got LTE working. In happy with it. I think the US phones work in Canada even with a bad imei.
Another area on a long long laundry list where canada is better than the usa. hockey and standardized healthcare being 1 and 2... hahaha
I was having the same issue on my Verizon v10 vs990 on my T-Mobile network. I went into the APN settings and set it to LTE/CDMA and it works perfectly. Calls, SMS and data.

Can I unlocked a thunderbolt and put my tmobile g2 sim and used it?
No. The TB doesn't use GSM as a radio and is strictly CDMA for the phone side of things. Also, the LTE radio is different than T-Mobile's 4G radio. I'm sure somebody with a more technical side of why will come in, but that's the basic reason it won't work.
the only carriers verizon phones can switch to is cricket and and sprint (if either carrier is even willing to activate the phone on the network).
T-mobile can only take unlocked GSM phones (which would mean att phones)
I don't know enough about the thunderbolt being used on different carriers cause I don't fully understand exactly what data is being stored on the sim card. If it is only 4g data than theoretically It should be able to work only on sprint/cricket (without 4g, if they are willing to activate it).

As above, no, you can't use it on T-Mobile, you could take it over to Cricket/MetroPCS. Metro I know uses 4G LTE, so you'd be able to get everything out of the phone. However, I know roaming with that provider sucks unless you don't travel anywhere.

MetroPCS uses a different frequency band for their 4G LTE (I think they're on 1700, and Verizon is on 700), so the LTE won't work.

No you cannot take it over to Cricket/MetroPCS. The phone does not have a traditional MEID to allow it to work on a traditional CDMA network, and the LTE radio is not compatible with the "LTE" system that MetroPCS runs.
GSM
If you don't know what you're talking about then don't post it. Obviously you don't have a Thunderbolt to say if it can be unlocked or not. HTC Thunderbolt uses GSM network on 4G LTE. It can be unlocked, but haven't figured it out yet.
NO CRICKET OR METROPCS can be run on it.
I took out my sim to see if the phone will work on 3G. And the result is no. No way of putting it on cricket.

LTE is not GSM. The Thunderbolt runs on 700 MHz LTE and 850/1900 CDMA. It does NOT support ANY GSM/UMTS/HSPA bands. You CANNOT take it to ANY GSM provider. If you were able to unlock it, you MIGHT be able to take it to another LTE carrier, but ONLY if that carrier also uses 700 MHz for LTE (for example, possibly AT&T once they launch LTE), but even then you'd be able to use it for data ONLY. It is unlikely that you'll be able to use it on another CDMA carrier either (such as Cricket or MetroPCS) because it isn't provisioned in the way all other CDMA phones are.
Jumping on the bandwagon, no.

The TB will NEVER work on any other carriers GSM network. Period. End Of Line. It is not a matter of "unlocking" the phones. The LTE standard does not define interoperability with existing the existing GSM standard. The TB cannot operate on a traditional CDMA network (think Cricket/MetroPCS) because it is missing fundamental components required in every CDMA handset (there is no hardware MEID on the TB). Without an MEID the device will not work on a CDMA network, no matter how much unlocking you try. It will not work because the network cannot talk to the phone and there is nothing you or anyone else can do to change that fact.
What VZW has done is create a hybrid system linking their LTE network with their CDMA network. There is a reason dialing *228 does nothing on the TB. There is nothing for the system to update. All of the settings are created on the LTE network and are pushed to the VZW CDMA network on their back end. Your phone number is tied to your SIM card on their network, not your MEID. Want to prove it to yourself, take the sim card out of your TB and put it in another TB. Care to guess what happens? I'll help. The new TB you just put your SIM card into will now have your cell phone number. Now if you have been with VZW for more then 5 seconds you would know that with every phone prior to change your number you had to call customer service and they had to update your MEID and in turn you had to update your phone (*228) so the CDMA system knew what phone belonged to what number.
Tl; dr...: LTE and GSM are not interchangeable terms and technologies. LTE radios cannot function on existing GSM networks. TB is not a true CDMA device and will not work on a traditional CDMA network.
My nexus 5 died and i need a new phone. I have a Verizon LG G3 that I can use but I cannot get it to see LTE, only HSPA on AT&T.
I did some research and it seems I need to unlock carrier frequencies, or something similar.
SInce the phone has TWRP and is unlocked, is there any specific ROM I can flash to unlock all carrier frequencies? I really liked that with my Nexus nearly anywhere I went in the world I could just buy a sim, pop it in, and go. No hassle.
Thanks for your help in advance.
thats not needed with the VS985, all you literally have to do is insert your sim card, and then get the proper APN settings and thats it
It's just that the vs985 only supports band4 LTE on AT&T. In some coverage areas AT&T does not offer band4 LTE. If you are in a non-band4 area, you cannot get LTE from AT&T there, HSPA is the best you can get.

There was a thread about this but it just kind of died without any answers. I know the complication with this is that Verizon is CDMA. I was talking with a friend that's a Verizon cell site tech, and he said that all the new sites and small cells are LTE bands 13,4,2 only... no CDMA. Of those 3 bands, the tmobile has 4 and 2. Some, I have read, are able to use their Verizon v10 on tmobile. So I'm wondering, with the fact that the new sites and small cells around me only uses LTE and not CDMA, am I able to use a tmobile v10 on Verizon? Has anyone tried it?

I will soon be testing this. Bought a unlocked tmobile v10 off swappa...gonna try it with my Tmobile prepaid sim to see if I can actually use their service in my apartment....then will try my active VZW sim. According to spec pages i have read, should have the correct bands for LTE for vzw.
Sorta worked. The t-mobile V10 recognized the VZW number and sim. Calls worked (disable Wifi calling and volte). I had to add VZW APN settings, and it connected, and recognized Verizon network, but I could not get a internet connection. Not sure if i had the wrong apn settings or not.
how were you able to edit the apn settings? when i try i get an error, i've unlocked, rooted, deleted the telephony.db nothing seems to work.
Hi there, i was able to get one of these from a local walmart for about $150 bucks, its a Verizon Prepaid samsung Galaxy S4 i545PP i545ppvruaoh7 is the build, and it comes with lolipop.
the reason why i bought is is because according to http://willmyphonework.net/
this phone was supposed to support 4G LTE Band4-AWS , but it does not!
it sure comes unlocked, i can put any sim card and i get signal, i get 2g, 3g, H, H+
I tried different sim cards and the best it can do is H+ on all of them.
I tried changing it to global, and also changing it to LTE GSM etc on the android menu but i have no luck.
Is there any way to enable the 4G on this phone? I live in a contry where all carriers use the same 3G and 4G that At&T uses. So here all At&T phones got 2g, 3g,and 4g out of the box. And i thought this verizon phone supported 4G Band4.

Are you sure ATT uses band 4 (AWS - 1700/2100) in your area? ATT uses a number of different LTE bands in different areas, and the Verizon S4 (prepaid or not) only supports band 4.
im sure my carrier uses same band as At&T, 100% positive that my carrier uses Band 4.
reason is because i also bought two other phones, a moto E At&T gophone and i unlocked it and i got 4G icon at first boot with the carrier here.
but verizon galaxy S4 prepaid is different, i can´t get more than H+, i have never seen the 4G icon
and i dont think there is a hack for it to enable all bands
I have an AT&T LG G5 unlocked and with a verizon sim card.
I checked the specs and it does say it has the correct bands.
Why with the correct APN will I only get 4GLTE Data, but cannot make or receive calls or texts?
When i try to place a call it just comes up and says "Mobile network is unavailable" even though i have service bars. Then when I hit ok I can see in the dialer app it says "Out of Service Area".
I've tried everything. Thanks in advance.
Because AT&T is a GSM network and Verizon is CDMA

To better explain it. Both companies use similar LTE bands for data but Verizon (and Sprint) still use CDMA for voice service while T-Mobile and AT&T use LTE or GSM for voice (depending on what area you're in). Sprint and T-Mobile use slightly different LTE bands than AT&T and Verizon. I could be wrong but that is at least how it has been in the past.
Yeah i understand about verizon being CDMA. And that makes complete sense. Thanks!
