Unlocked T-Mobile LG V10 switched to AT&T, but LTE does not work - T-Mobile LG V10 Q&A, Help & Troubleshooting

Hi, I have an LG V10 that I purchased from TMOBILE. I switched to AT&T, and brought my T-Mobile device with me. Everything works fine, but I cannot get 4G LTE service at all. I have tried 2 APN settings, and that does not help. I live in a large metropolitan area, and I know that 4G is available here with AT&T. Does anybody have any idea why I can only get 4G and not 4G LTE?
Thanks!

This happened to me when flashing a custom Rom, the fix for me was to change the network speed to 3g or 2g then keep changing Ap's until you see you are connected to a network. Once you see that you are connected, change it back to 4gLTE. Let me know if this worked for you.

This is the APN I use and got LTE to work. It's old APN but it works for me.
Name-LTE
APN-phone
proxy, port, username, password-Not set
MMSC-http://mmsc.mobile.att.net
MMS proxy-proxy.mobile.att.net
MMS port-8080 (In order for MMS to work with adblock plus, I use 8080 instead of 80 because using port 80 will cause the MMS not to work)
MCC-310
MNC-410
Authentication type-Not set
APN type-default,mms,supl,hipri (hipri is what makes LTE to work. Without using "hipri" I only get 4G, not LTE. No need to use "fota". It is for tablets)
APN protocol-IPv4
If changing to this APN setting and you still don't get LTE, reboot the phone.

Wow, i was thinking i was the only one with this wierd problem, i had a lg g3 tmobile with this issue, when i was on wifi for large periods and the back to data, the 4g lte appears like it was working fine, but it never gave me access to inteternet, then i had to revert to 3g or 2g, and when it connects and works, i revert back to 4g lte and works fine, until i get wifi, and the same all over again, but this only happen to me with lg on tmobile, i had htc, samsung and this problem does not seems to happens with that brands, so i tougth it was the lg g3 itself and i sell it, but now i get a brand new v10 with tmobile and the problem is still the same, and i don´t find anything on the internet about it, until i see this post, do you know why is this happen? im on mexico, and i use my phones whit telcel

Have you tried apn unlcok?
Diag 277634#*# and look for the "APN UNLOCK" option

when i hit the apn unlock option appears a message that tells me: "apn has been unlocked" or something like that, but the phone stills the same, do i have to do something else besides manually enter apn settings from my operator?

A word of advice I have an unlocked t-mobile lg v10 and I have had the same issue as you and believe me I tried every possible fix and nothing worked until I tried this fix ( put your sim card in another AT&T device in my case my girlfriend has an AT&T iphone 6 and leave it for a minute or 2 once you see the 4G LTE on that device remove it and put it back into your phone and you will have the 4G LTE all the time, of course you need to set up your apn but like I said I spent a whole month and tried everything before I came to that fix because nothing else worked) I hope that would help you.

I totally switched iphone 6 SIM on unlocked LG v10 ,,,but i saw LTE for 5sec and then back to 4G ...
Don't know if it will work ..

Just a network access problem, you should save yourself some time and just.... Call AT&T customer support?
Or hit the AT&T V10 forums for correct APNs. I'm sure you aren't the first person to deal with this issue.

Yes u can have 4G LTE ...just activate with a AT&T 4G LTE IMEI

i have the same senario...recently moved to AT&T with the UNLOCKED Tmobile LG V10 and every thing works just fine with AT&T SIM except no 4G LTE and when you asked At&T they will try to convince you to buy their device to get 4G LTE signal....it took me a while to figure it out that u can get 4G LTE on an unlocked LG V10 if u activate the service with any AT&T 4G LTE capable device IMEI..... One more thing.. u are on your own to provide the LTE capable IMEI to customer service. That means don't except to walk in to AT&T store and borrow the IMEI from their display unit..coz they wont let u do that.....

The T-mobile phones pick up perfectly on ATT, it's most likely an APN related issue.

[Q] Data not working with unlocked Aria on tmobile

I recently unlocked my HTC Aria (Att) and am using it on T-Mobile but it will not connect to the data network i can text and call but not access the internet from tmobiles network. I have been trying to figure out how to make it connect and don't know what to do. I tried setting it up to a new VPN but i don't know if i did it correctly. I am aware that it will only be an edge connection but something is better than nothing. Is there anyone that could help me out?

If you were trying to set up a VPN, that is the wrong option. You need to set up APN settings for T-Mobile. I'm sure if you search you will find the correct settings you need.
So an unlocked Aria's data will work with T-mobile?
Will an unlocked T-mobile device function fully with my AT&T sim card?

Yes to both questions. That's what unlocked means.
The only thing that won't work is 3G data because AT&T and T-Mobile use different frequencies for 3G.
2G data will work fine.

The answer is Yes and No. If your term 'fully' includes 3G data access then no in both cases you will not get 3G data speed. You will only be able to get Edge data, which is pretty slow. So if you need voice and text service and don't mind slow data speeds then go ahead.
Thanks. Well I actually have the problem that I don't get 3G on my Aria for whatever reason .-. Even though I emailed them and they said I should be able to get 3G all I have ever gotten is EDGE. l:
I asked this because I was looking at getting the new Sidekick, but I am seeing if it would be better to just go ahead and switch to T-Mobile, or staying with AT&T and buying an unlocked Sidekick.

Does your Aria have the AT&T logo on the top right? Also, check the model number underneath the battery. If it says A6366 then it should support AT&T 3G frequencies. If it says A6380 then it won't.
How old is your SIM card? You may need a newer one.

I already made a thread for this and couldn't figure out what was wrong, but what was weird was that like 30 mins ago I disconnected from my wifi because I moved my router and stuff, and I was getting G not E, but now that I did it again I am only getting E /:
That was the first time I saw I was getting G
And yes it's an AT&T one, it hasn't been too long since i've had it.
And the under the battery it says A6366

I suspect the "G" you were seeing was for gprs, which if I am not mistaken is slower than edge. Somebody jump in and correct me if I am wrong. If you are running a stock rom, you would see a "3G" not just a "G" if you were actually getting 3G data connection.

G is slower than E. It happens sometimes just because of the nature of wireless networks. Nothing to worry about. When you are getting 3G signal it will say "3G" or "H".
You should really do two things -- first make sure your area actually has 3G. Go to the coverage viewer on AT&T's website, click on "Data" at the top, then see if your area has dark blue ("Mobile Broadband" is what they call 3G on that page). Of course the other way to know is if you have any other AT&T phone that can get 3G signal at your location -- or perhaps a friend's phone.
If you are sure your area actually has 3G coverage, then I'd try going to an AT&T store and asking to switch to a new SIM card. Just explain that you can't get 3G signal on your phone and they should do it for free if the SIM card is old.
Good luck.

Lost LTE with GS3 on Rogers?

For some weird reason, ever since i got my GS3, i lost LTE. Its odd because i come straight from the skyrocket so i already had the lte data. But since i got the GS3, my phone can only connect to 4G (NO, 4G is not LTE, its H+). So i called rogers tech support, i spent about 4 hours with them, making tests, getting transfered to level 2, then to customer service to make sure i had an lte data plan...finally they told me your phone is broken to get a new one. So i go to rogers, they give me a brand new GS3, same damn thing...only getting 4G. We tried 3 different sim cards, nothing.
Then i call back rogers, they transfer me to the "above level 2" which they told me is the master departement. They guy tells me they will emulate my sim card in their lab with a GS3 they have...but nothing. All settings seemed right, APN and everything was good, so they finally opened a master ticket.
But for some reason, i dont beleive i'll get a call back anytime soon, so anybody might have any suggestions?? I'l fully stock, not yet rooted
Try performing a manual network search, then select Rogers to have it manually "Register" on the network.
For some odd reason, I had the same problem as yours, but after manually registering, LTE was back on, I switched it back to Auto after
check the sim card, there is also a chance that they gave you a 4g sim card and not an LTE one (bell did this to me)
If its LTE then go to the dialer and press *#2263# choose LTE and then LTE all (when you are in an LTE area) when it connects to LTE data do the same thing again but select automatic.

euff yeah, i think i would have checked for the lte sim card in the first place. As i said, we tried 3 different ones.
ill try that thx
Well selecting lte bands manually didnt work.
so then the sim does say LTE on it and not something like 4g? outside of manually selecting and waiting. I'm not sure what else. Maybe try getting them to give you a different sim and test in person. wish i could be of more help.

I already said that when they gave me the phone we tested 3 different sims. Same result. The only way i could isolate the problem is to have a person with a working GS3 on rogers give me their sim
I have never seen LTE when passing through an LTE area. Often I get knocked down to Edge while in Vancouver. No LTE where I live, bus something seems wrong. I was thinking of shutting off the 3g in network settings to see if that helps.
I am new to Rogers and not use to getting bumped down to Edge, as Telus only has a 4G network. Does this happen regularly, or is it a phone issue?

GSM Works on DINC4G, Here is how to do it...

I was curious because I heard that the Droid Incredible 4G has a GSM radio in it so I did an experiment. I used a T-mobile micro SIM. I used the 4GLTE switch app for the Thunderbolt to access the hidden menu and I changed the radio mode to one that included GSM/W-CDMA. I popped in my T-mobile SIM and, presto, I got a T-mobile signal. I tested and I was able to make and receive calls and text messages. I had to manually set the APN for data to epc.tmobile.com and now I have EDGE data. I am sure an AT&T Sim will get HSPA+. The GSM appears unlocked now but hard to access. I am afraid, however, that once Verizon releases the update to make GSM roaming available, that it will be locked. Anyway, for now, you can pop in a GSM SIM and use your phone native.

Works on AT&T with EDGE data as well. I haven't gotten HSPA (any variant) or AT&T LTE working, and I can't play with it too much because it's not my SIM
ATT LTE won't work because the frequencies are different from Verizon but I am surprised that HSPA didn't work. Did you use a setting that included W-CDMA? GSM only would likely mean Edge only.

Im afraid I cant get this to work. Does it require a rooted phone?
I have the app, I have a T Mobile micro sim installed. I click on the drop down menu (within the app) and choose the first menu item "Select radio band" and pick PCS (1900-MHz Band) and I get a "successful" prompt afterwards (only when the Tmo sim is installed btw).
I am unable to choose "GSM Only & GSM auto (PRL)" menu choices. Is this normal? I am able to choose GSM/WCDMA/LTE auto though. I dont get any sim error messages, but the phone never seems to want to camp on any GSM network.
You are looking in the wrong place. You need the drop down menu that includes GSM, W-CDMA, EVDO, LTE in various combinations. Select one with GSM in it. Also, I found that you need to have your Verizon SIM in first and then hot swap it with the t-mobile sim.
On the Rezound if you make a couple build.prop tweaks it fixes texting and data on GSM.

No, I was in the right place to begin with, I just thought it would be able to pick just gsm but it wont.
And you left out that piece of informationin bold, but still not working...
Can you give us your firmware & radio version, perhaps some phones have been updated to block this.
Anyone have any luck with this?
OP, is your phone stock? Rooted?
What if it has a bad ESN will this work or a way to make gsm work even with a bad ESN I'm asking because if Verizon does not have droid 3 s I will get this phone then go with at&t but will like to know if I can change the radio so I can so this

One additional thing I found was that I got it to work by hot swapping the Sims. It seems like the Verizon sim has to be in when the phone boots. Once it boots, use Phone Info to change the mode to GSM and then switch your sim.

I would think it should work. The ESN is used for the CDMA networks, the IMEI is used for GSM. Stick with GSM and you should be ok...

[Q] Using 3G network instead of 4G on HTC One

I'm wondering if I'm the first guy on earth experiencing this problem.
I got an AT&T unlocked HTC One (M7) in the US and brought it with me to Brazil. I introduced the SIM card in it and it worked perfectly for phone calls. However, I can't get the internet access through the network. Brazil only works with 3G at the moment.
I called HTC and they told me to dial *#*#4636#*#* and change the settings for the network under "set preferred network". They told me there would be no guarantee this would work, but I should try.
I tried all the options from WCDMA, CDMA, GSM Only and so on and still could not get the mobile data access.
Right now, internet works only with Wi-Fi. So, he said that I could try finding help on XDA Developers.
So, is there anyone who knows what I should do next?
I wonder if rooting would resolve it, but it seems pretty much a device problem.

Make sure you have a 4G sim and make sure you are in a 4G area
But also, are youtalking about hspa+ or LTE?

I'm not in a 4G area. Only 3G.
That's why I need to change the settings. I tried also setting the APN settings and nothing so far...

take the same sim card in some local 3g andorid phone in brazil and try again .to make sure your sim card support 3g network , and you say you can not access network by your phone. i doubt if you have a data plan .maybe you should take a phone call to your carrier to check the data plan of your sim card
Thanks for the tips. I solved my problem by calling the provider. It was ANP setting issue. I wasn't getting it right the way it was supposed to.
Thanks again!

[Q] Xperia Z2 US T-Mobile LTE Connection Issue

I've had my Z2 for over a month now but I've been unable to connect to T-Mobile's LTE network here in the US.
I know for a fact there's LTE in my area (I live in Seattle). Other phones have had no problem connecting to LTE.
After talking with T-Mobile's tech support I should have the correct APN settings. They also refreshed my phone on
their network. It helped somewhat. Before they refreshed, I couldn't detect the LTE network. Now I can detect it
but can't connect.
If anyone can give me some advice as to how to get things up and running that would be most helpful.
I've attached some screenshots that may help in diagnosing the problem.
I'm on T-Mobile in Los Angeles, and those are my settings... The only difference I have is the APN protocol is set to IPv6. Not sure if that makes a difference. Otherwise, we have the same exact settings and my LTE works fine.
Call TMo. Sometimes they have to reprovision your phone on the backend. I had that ptoblem with my Z1 but not with Z2. My APN type is blank. The settings can be found at TMo site. If you cannot find them, call TMo and they wipl email that to you.
Sent from my SGP312
Thanks for the suggestions.
I changed to IPv6, IPv4/6; I still get H+ but I dont get LTE.
I did call them, I guess what I meant by refresh was "reprovision". When I first got the Z2 I couldn't even detect LTE with network search.
But after talking with them; I was able to see the network. But for whatever reasons I cannot connect to it.

Might be a stupid question, but are you using an LTE-compatible SIM card?
haha, no that's actually a good question. I wasn't before but I went to t-mobile and got a new lte compatible one. but nothing's changed. i'm thinking maybe there's something wrong with the sim card.
Mine hasn't said "LTE" since I updated to .402 FW. It says 4G now instead, does yours show neither LTE or 4G? I get H+ in some areass, so I know there's a difference between the symbols (even if Tmo likes to think they are both 4G).
Try flash .438 ftf file via flashtool
To see can solve it.

I flashed unbranded. 402 ftf from Germany when I first got my device. Then I deleted the factory t-mobile apn that it downloaded and used these settings. They always work for me with unbranded international devices!
