Ive been doing research the last few days and havent been able to find much info. Im hoping I'll get some help here. Currently I have a tmobile galaxy note 3 sm-n900t. Im switching to viaero wireless who recently activated there 4g network. I have been unable to get my device to connect to there h+ even after using tech support. The phone is rooted and sim unlocked with stock android 4.4 running. I have tried several apn settings but nothing is working. Does anyone have any suggestions to make it work? With the network mode on auto I can access edge but cant get h+ (thats what tech support said I should see). Im wondering if I need to get into service mode and make some changes. Ive tried researching how to get into service mode to modify settings without any luck. Thanks

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 have an unlocked i717 that I've been using on tmobile for the past 2 years but I just switched to Straight talk so that I can use At&t's network which is much better in my area. I'm running stock 4.1.2 and I've tried several At&t Modems. I have the correct att APN but I still don't get any service. Under select networks I can't select anything. Any tips for modems/rom combinations that work on straight talk?
So after some fiddling I did manage to get connected so now I can send texts but I still don't have any data access, not even edge. I do have the correct APN.
What type of "fiddeling" did you do? You seem sure of the APN, I have been using ST for a long while and use the latest APN from their support website.
Heres the funny thing, I think I've got it all working. What I did: nothing. I let is sit overnight, after the Straight talk website said my number transfer had completed, and magically data was working in the morning. So I guess I'm all good.
I'm using the UCMD3 modem with straight talk and get 4G coverage in most nearby areas.
Same situation here...although I have to travel to "reach" any 4G!
i have a galaxy mega gt i9152 dual sim international phone. im runnin an att compatible straight talk sim, i have service, but mobile network type says edge2. really slow data. i have the correct apn settings. ive even been to att and they tried one of their sim cards and still couldnt figure it out. if i select gsm/wcdma auto connect it will show the high speed data logo but the data dont work at all, if i dial #*#*4636*#*# it says wcdma preffered, but im usin gsm networks, it wont let me change it to anything besides gsm only, but then its stuck on edge again. theres some other secret menu i tried to get into debug mode where there is supposudly a setting to lock it to 2g or 3g but when i dialed it just said USSD code running, and then displayed my phone number. it was rooted and unlocked when i got it, i flashed it with stock firmware, still had the same issue, i tried a few different countries of firmware, no difference, currently running the uae jellybean stock firmware. i tried calling samgsung and they said i have to call the country of orgin which i guess is india, so i got an international calling card that i guess cant make toll free international calls. so im at a roadblock, i know its gotta be something stupid but i cant figure it out, been messin with it for 2 weeks and searching forums till my eyes bleed, so im makin my own thread now.
so now that ya know my situation, what do i do, how do i get my fone to work on 3g
Hey all, I'm new to all this 'phone personalization'. I was recently given this phone, but don't live in a Verizon network. I've set it to Global, and LTE, and it has a hard time staying connected to any one network. It also uses a lot of battery constantly searching.
So, I've rooted the phone, (got rid of some bloatwear) and would like to be able to set it to a specific network. Are there apps for this? Do I need to have a special rom?
Any help would be great, Thanks!
Um, Verizon phones only work on Verizon networks or similar CDMA networks. Sometimes you can unlock for GSM, but I don't think you can. I don't know for sure though. And custom Roms are out, because you have a locked bootloader (unless you have one of the original bootloaders from way back). Since you are rooted, you can try some network settings apps, but these wont help if the phone does not natively support the network you are trying to connect to.

Hello people. I am hoping for some help. Have s4 mini I9195. Unlocked. Currently I am connected to T-Mobile network. However can only get 2g in my area. So bought, activated, registered, and paid for att account. Now have both T-Mobile and att. However, when plugging in the att aim it WILL NOT connect to att. I get 4 Signal bars on phone but no connection. Have correct apn. Spent two hours with att it's not on their end. Sim card works fine in different phones and other att sims WILL NOT work in my phone. So we know it's NOT a Sim issue. And remember T-Mobile network is connected and working. Only att is the problem and will not connect. Any ideas?? Please help??
I'm on the verge of flashing custom recovery, rom, gapps, to maybe fix this but want to make sure I am not missing something more simple first.
I've done all the basic stuff from resetting phone, apns, closest tower, etc.. Just see seems like phone will not accept att now. It did for first night for about 15 mins got texts and Signal, but nothing since. I am stumped.
Thank you for any help
