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

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 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.
Hi!
Rooted with cmahendra's offline Lelus method (and to anyone who's done that, my hat is off to you).
**SHORT VERSION**
Sim goes into the L9. I get bars that show network availability, however I am not able to connect/make/receive phone calls.
**DETAILED VERSION**
Starts like this: I have my CM rooted Aria that works a-ok as far as the network. Phone message memory getting full all the time and incoming texts bounce back, with no way of knowing who sent them. Can't have that, so I buy a stock L9.
Sim works. I want to have Wi-Fi calling, which is the *only* reason I bought the L9. Wi-fi calling is not working: call up T-Mo and they say I need to give a 911 address and all will be well. Ok, done.
Sim works. But no Wi-Fi calling still. Call up T-Mo and they say "Ohhh! you need a "3G-B" (I don't think that stands for gigabyte) sim card" Ohhh and what's your phone model etc etc. I tell them "it's a no-brand phone I got overseas," they don't need to know the model: they didn't with the CM Aria. They're clicking settings on their screen other side of the phone while we're talking: I can feel it.
Sim *stops* working. Need a working phone, so let L9 aside and get a stock T-mo S2. Same issue, cell network not connecting.
Let me show THEM! Ha! I'll unlock it. Unlocked the S2.
Sim still doesn't work.
Put the Sim back in the rooted/unlocked Aria? Network works.
What settings do they have in their stock phones that disallow network connectivity, because in the CyanogenMod Aria I have the phone fully works, GPS, tether, etc etc. In their stock-from-T-Mobile phones, network = nada.
Thank you for reading.

What the heck are you asking? I don't see any understandable questions in your message. I see you blowing off steam.
It does look like T-Mobile cooked your sim. You may need a new one.
Call them again and ask for "Customer Retention" through the automated system. Those people are more knowledgeable. A new sim should be free if they killed it.
Also, a data plan is not required for wifi-calling.
T-Mobile will give you a SIM regardless. They are always free.
I'm not sure as I am unrooted, but most carriers block network access via files in the EFS folder. This folder is VERY delicate. Anything improperly changed here can render a phone useless. If the SIM works in another device, it's not the SIM. Have you tried a different SIM in your phone?
Also, if you're blocked from network access, when you make a call, you should be prompted with, "We're sorry, but this device has been blocked from network access." If you do not get that prompt, then there is something wrong with the phone itself, be it software or hardware.
Looks like the L9 isn't registering in their system. Where did you buy the phone, blacklisted perhaps?
As for fried your sim, why does it still work in the Aria.
As for 3G-B, you probably need a newer sim, others call it a 4G sim... They should send you one free or pick one up free at a local tmo..
Thanks so far folks...

You hit the nail on the head exactly clockcycle, it's not registering. Something *in* the phone is not letting it connect, because my sim works successfully in any and every other unlocked phone I have, blackberrys, GMS world phones, the rooted Aria, but in the two "newer-released phones-- the L9 and the S2-- it doesn't work.
Phones are legit. Craigslist and brand new. Worked perfectly until calling T-Mobile for "support". The sim is fine and the goal is to keep it and not get a new one. It works.
My strong guess is that if I put a different rom that is *not* stock, the phone will work fine. It worked fine in the beginning, until I called them to address the wi-fi calling issue and they started poking around in my account, asking questions and clicking on things. I didn't want to address the wifi-calling issue too much because we could go off on a tangent.
You're right kevev, it didn't look like there was a 100% clear question. A lot of story though, to make sure there aren't 50 posts of did you do this and id you do that. A full story gives everyone the most info they need to understand the situation instead of "yo! my phone is not connecting!" which we see sometimes .
So the more clear question is:
"I am experiencing carrier settings *in* my L9 that are blocking me from connecting fully to the network on a perfectly fine sim card, how can I get around these settings and what/where are they."
I think tribalartgod understands what I'm getting at most completely. The inside-the-phone-settings. When the sim is in the phone I have bars, but when going to make a call the screen message is "emegency only". Can't try different sims in the L9 because of the need to cut the sim down. Also the L9 is not unlocked, just rooted. My guess is a de-bloatwared rom is the fix. Looking for answers from people more knowledgeable than me which is most likely all of you. Thanks again!
Craigslist, new, boxed, doesn't gurranty they aren't blacklisted.
BUT, the Aria uses a miniSim, the L9 uses a microSim. Did you cut your Sim yourself? It might be misaligned, cut wrong.
It's less than $2 to get it unlocked..
It sounds like its IMEI blocked dude. This can happen with various insurance or installment plan scams, even to brand new devices. There are options to still use the phone, but you are hosed on T-mobile. I have a blacklisted L9 because the previous owner quit paying his EIP, but it's unlocked so I used it on an AT&T MVNO connected to an AT&T MicroCell (I wanted WiFi calling too, but that won't happen with a blacklisted IMEI). Until you've gone to T-Mobile's chat support and ask the if the IMEI is clean, writing long posts in this thread is futile, and it is pretty clear everybody in this thread THINKS they know what they are talking about, but nobody has simply asked T-Mobile about the status of the IMEI, which takes two seconds.
I've searched and didn't find any thread with this kind of issue specifically. I have a Verizon Galaxy S4 that doesn't seem to like GSM SIM cards; it looks like it is not GSM unlocked. I have tried every trick to get it to switch to GSM but it doesn't. I have flashed the same version firmware it came with (ME7) just to be certain it's factory restored, and also updated to MK2, yet no GSM. It sees the SIM card but doesn't show a signal, even when I manually switch to GSM/UMTS. I have programmed a CDMA number on it manually then tried the GSM switch again, yet no GSM signal. It sees CDMA signal fine though and can even make calls on CDMA. I even had to check the MEID/IMEI and it came back clean so I'm just surprised at all this. I have done this before successfully on a Verizon S3 and it worked well, how come the S4 has refused to work on GSM?
Please help, anyone?
Did you input APN's?
I thought APN settings had to do with data. I will do that now. I'm willing to try anything now.
Thanks.
I am having the same issue with a couple s4s from verizon as well. Checked the IMEI/MEID and they come up clean but they will not catch a signal with a gsm SIM card. I have tried several active AT&T and T-mobile SIM cards in the phones with the same results, no service/signal. Very strange as I have never had an issue with verizon S4s working on AT&T or T-mobile. The weird thing is that with a verizon SIM they catch signal and 4G just fine. Toggled GSM/CDMA and put in APNs and still no luck. I'll keep trying to work this out but right now I am stuck.
I had the same problem here
My GT-I9505 Rom Stock 4.4.2 ZTO(Brazil) had the same problem about signal problem.
Everytime i lock my phone (turning off the screen), by the time i light it on (lock screen), immediatelly my phone turns the signal to "No service".
In this time, i need to wait 1-2 minutes to the phone turns okay. Just wait.
I search for a lot of solutions and didn't find anything.
Notice too that the problem appears only network 2-3g. 4G didn't have the problem.
I solved this problem after Lollipop update. The problem simple dissapear!
(Sorry my bad english)
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.
