roam on att help - Vibrant Q&A, Help & Troubleshooting

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?

Talk Mobile UK issues

I have had my TITAN since about a week after its release. At that time, I was using an O2 SIM card and everything was perfect and fine.
Around 4 weeks ago, I switched to Talk Mobile as my O2 contract was up and I got a deal from Talk Mobile. Since then, my phone has been a disaster - but I dont think the TITAN is at fault.
Around 50% of all my calls get dropped. Typically, when this happens, I will be connected to a 3G/HSDPA network with decent signal strength. The call will drop, I look at the phone and the signal has been lost entirely. Then the signal comes back but at GPRS or EDGE. I also often have a GPRS or EDGE connection in areas I know have strong 3G signal. The phone will transition to 3G eventually but it is a right pain.
I am already on my 2nd Talk Mobile SIM card and will try a 3rd this week. I have tried hard resetting my phone too. None of this has helped and the network have so far been typically useless in trying to help so I was wondering if any of the bright people on here would be able to help at all.
Many thanks
Sounds like a network issue, I am on Vodafone and have not had any problems with the handset. Make sure you have correct network settings installed on the Phone like APN's etc for Talk Mobile
Are they listed in htc connection setup? if so run it.
Talk mobile piggybacks vodafone iirc. i get this problem of switching 3g/edge/gprs with vodafone and talkmobile. with talkmobile if its a phone they don't sell they don't seem to have the settings for internet/mms etc. i usually have to manually input them.
If you need to manually input the Talkmobile settings, they're all on the website.
Click the second orange button 'Talkmobile phone settings' and they should be listed in there.
talkmobile.co.uk/get_your_settings.html
Thanks to all for the responses. When I run HTC Connection Setup app, there is a setting for Talk Mobile which I selected. Before doing that, I had no internet as obviously Windows Phone on its own doesnt have the right settings.
I will try manually entering the APN details next and see if that helps, but I dont think the APN affects voice calls if I am right?
dumped o2 and got my titan with vodaphone. No issues at all. Maybe you can Complain ?.

I am complaining vigorously
You've checked the aerial right? http://forum.xda-developers.com/showpost.php?p=18523952&postcount=12
I have a Talk Mobile sim (I got it as it was an offer - unlimited data) and a Vodafone sim. I have the same problems with Talk Mobile.
E.g. today I could only get Edge in London, and it seemed to be slower than basic G. When I swapped to Vodafone sim, in same area, suddenly good H signal, and fairly fast.
Also my pop3 email sometimes just errors with the Talk Mobile sim.
When I first got this TM sim in November it was great, downloaded no end of music and data on the Titan. Past few weeks it has been rubbish. I find calls are ok though.
Haven't got as far as complaining.... yet.... sorry have no answer but just to say that I don't think it's the Titan at fault.

[Q] Straight Talk Help

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!

GT-I9195 mini will not connect to att

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

Activation on At&t

Got a buddy that picked up this phone, only getting hspa+ network. When I give him the standard at&t apn's he still gets only h+ no but no voice. Waiting to click the buy button for myself til his issues get worked out. Any tips?
I had the same problem. I tried changing the apn also which did not help. Ended up going to AT&T store to get a new sim card and had them check my account to make sure everything was provisioned correctly on my account for this phone. Left out with 4G/LTE and no connectivity issues since.
I used my AT&T SIM that was in my Note9 previously and put it into my Rog Phone and it just worked, had no issues and the phone reports 4G+ walking around, Id contact AT&T and make sure everything on their end is configured correctly.

Roaming Indicator Off and MMS not working

Hello, I just switched from Sprint to a Verizon MVNO and a few weird things are happening and I can't seem to find a lot of info or help for it. After sticking the new SIM in, it said it was connecting to "." and then it updated apps for "." After that, where Sprint or US Mobile should be located at the top left, it says "Roaming Indicator Off" instead. In the network settings it says the network provider is "roaming indicator off" lol.
The APN list is a dozen of Verizon related ones, and Verizon Internet is selected. I was told by support to use add a new APN., and it removed the long list of others and kept the VZWINTERNET one. The top left then read "Searching for Service" and I had LTE while it was searching but after 2 or so minutes it shut off and read "Emergency calls Only". I've tried putting the Sprint sim back in and fiddling with the settings there and switching back to the US Mobile sim, and it started to try to activate to the network but eventually failed and gave error code 6604. I'm assuming it was trying to connect to Sprint? Someone suggested taking a Verizon sim and seeing if that can install the Verizon personality on the phone, since it was still running Sprint OMADM and was in an in-between stage of being both Sprint and Verizon. I found an old Verizon droid and put the sim in. It got it to recognize as a Verizon sim, and now it boots up saying Hello Verizon, downloaded the apps and waited a while. Started to look good, it said it couldn't activate service but I'm assuming because there isn't any on it? Popped the US Mobile sim back in and still saying Roaming Indicator Off. MMS still doesn't work either. Also noticed I have a new APN, LTE Verizon Internet. I have another phone with an active Verizon service on it, but I'm not sure if that will work either. Maybe I'm more in Verizon land than no man's land now.. At least I'm getting somewhere.
I should also add this is on a Galaxy S9+ and was leased on Sprint, I bought it out over a week ago and ported over 2 days ago. MMS is also not working. Data, and VoLTE are though.
