my friend tom got his galaxy s like two months ago. he has a even more plus plan with unlimited everything on tmobile and he used that in a iphone 3g for a year with no problems and he could roam with no issues on att.
with his new vibrant its not working! it takes forever to try to connect then gives a error. the sim should be good since it roams in two other unlocked phones..
for the note, his phone IS unlocked... that was the first thing we thought of..
the error is: unable to select network.. your sim card is not allowed to connect to this network
this phone is a quadband phone so it should work.. we have put a att legit iphone sim in it and it works great.. what gives? why can't he roam on this new phone when other phones do? running bionix rom.. have tried updates, wondering if anyone has any opinions or info
we've already tried changing network settings with *#0011#, gone into service mode *#*#197328640#*#* with no luck
edit: we've tried not allowing the phone to connect to our local att 3G band (1900) and use all other bands again with no luck. the phone connects to canada's rogers network tho.. weird..
anyone check this out yet?? anyone got it workin? any reports would be killer ...
we have tried more settings through service mode still with no luck. when we specify certain bands and leaving the att 3G local band unchecked, it will not hop on T-mobile with the setting! Crazy! not sure if it's the rom, radio version or kernel but we will keep tweaking and posting results.. if anyone is having this issue or has concerns any posts or signs of life would be cool lol
Same issue
Unfortunately, I don't have a solution, but I've been working on this same issue since september. I originally contacted tmo about the problem to see if they somehow hadn't provisioned my phone/account for roaming. Needless to say they were not much help. They suggested I exchange the phone for a new one, which I did, and I still have the same problem.
I'm in a rural area of california where tmo has roaming on att towers. My girl has tmo service with a different samsung phone and she can roam on att just fine. She can send/receive calls and text. I even put my sim in her phone, and it works, so I've pretty much narrowed the problem down to an issue with the vibrant itself.
My phone is not unlocked, so we've ruled that out. I'm running bionix fusion with ji2 modem now, but I've had the issue with the stock phone before ji6, and after ji6 ota. I've tried messing around with the service menu the same as you, and I haven't got anywhere either.
I have been able to get the phone to at least lock on to att by adding the apn internet2.voicestream.com, and it will get past the "not registered on network" message. Unfortunately, it won't complete a call or send a message, it just times out after about 15 seconds and drops back to the previous menu (depending on whether I tried to dial out of contacts, the call log, or the dialer). But it does not give me an error message, it behaves as if the call connected and immediately hung up.
I had given up on it for the past couple weeks, but I have time now to try and work it again. Let me know if you've gotten anywhere, and I'll do the same.
The fix is: when you're in an att roam area, set your phone to gsm 850 only via the service menu. If your phone doesn't auto lock on the att network, search for available networks and choose att. After that you should be able to send and receive calls and texts.
after yet some more messing around, still no luck. it's clearly a thing with tmobile not allowing roaming..... because i read many threads off the gooooogle that say tmobile is pretty much going away and any "contractless" plans don't have roaming so they don't lose money....
dickheads. at least he's grandfathered in with a good unlimited everything plan tho..
even if all this said, if anyone finds any info out post!
the other day i was out of tmobiles network coverage and on att voice and edge not 3g. i live in texas
this is with a stock vibrant jI6
tried the app RoamControl with no luck. it uses different tmobile bands when in "roam only" mode. anyone have any luck yet?
I'm not sure if this is an isolated case or not but we picked up an Optimus T 2 days ago, got the unlock code and not for anything would it connect to AT&T's data network. I entered the APN settings about 20 times and still nothing, went by the T-Mobile store, they said go to AT&T. AT&T said they're not helping since it's not one of their devices (expected). Eventually after a few more hours of tapping away and staring at the Testing info (*#*#4636#*#*) and realizing that it was still tryin to connect to T-Mobile's data network despite entering AND SELECTING the new AT&T settings i entered, I found the fix by accident when I wondered what would happen if I used the Broadband APN
Simply create another APN (in addition to the first which apparently was a dummy or not being read) with the AT&T settings and it works fine! So I have 3 APNs in the list total, the original T-Mobile, the placeholder AT&T and the actual AT&T.
Hope that helps others as I searched the net for hours and couldn't find a solution.

What is the Broadband APN? Is that isp.cingular ? I assume the placeholder AT&T still points to wap.cingular?
Also, what data freq band are you connected to on AT&T? I read somewhere that Optimus T (T-mobile) will only connect GPRS data on AT&T's network.
Please share your obvervations! Thanks.
Yea the placeholder does point to wap.Cingular. I didn't use any broadband APNs in my final settings, it just helped me discover the need for a dummy APN on my device when analyzing the "testing info" screen. I'm connected via EDGE (2.5G) which is faster than GPRS but not 3G due to frequency (hardware) limitations.
Hope that helps....
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.

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!
2219
The icon im getting is 3G/H+
Singtel .438 didn't work; same problem;
It might be an issue with my baseband.
I have
8974-AAAAANPZQ-00005-09
I'll try flashing germany .402 now.
I bought this phone and it seems that I can get 2&3g but not 4g. I'm wondering if anyone is currently using the phone successfully. I have the emerald green one if that makes a difference. I have called tmobile, she said everything seems fine. I'm confused and extremely disappointed. Thanks anyone for your help.
UPDATE:
I called T-Mobile last night and was asked if my APN network is "T-Mobile US LTE". I stated no, but she continued on to other things. I had in inkling that that was what the issue was. I let it go, and decided to call T-Mobile today and speak with tech support again. I asked about the APN network. I explained that the name did not have T-Mobile US LTE . She had me add a new APN, and it magically worked. Please check your APN and see if it says LTE. It makes a difference. If you need help, message me. I will give you the APN information!

I'm thinking about buying the SM-G925F version (because I'm interested in the emerald green color) but would be using it with T-Mobile in the USA. Have you had any further issues with yours on T-Mobile?
I couldn't find clear confirmation that the international version supports Band 12... have you been able to connect using Band 12?
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

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.
