So I have an ATT sim card and a Cricket sim card, both are activated. I was going to go with ATT prepaid and for the past 2 days my phone will randomly drop to 1 signal bar and then completely goes to "no service" for about 2 minutes straight with the ATT sim. I put in my Cricket sim and I have perfect service, with only drop in signal roughly once an hour. How is that? When both are on the ATT network. Is it an issue with the phone, the sim, something? I have my APN's set up properly as well.
If I had to guess, possible antenna issue, also I would try the ATT sim in a different phone.

I recently decided I loved my Aria so much I was going to purchase the unlock code so I could use it on a prepaid service (I no longer use at&t).
I am ROOTed, and am running the Liberty Sense 2.2.2 ROM.
After I inserted my T-mobile pre-paid SIM and got the message "enter SIM unlock code" I did as instructed. It said it was accepted and My phone booted without that annoying please insert sim message. Yay right? Nope it can't connect to the mobile network. After doing a little googling and hunting around I found that the phone has to be compatible with the GSM frequency that the company your planning on using has.
Well this is what my device supports:
HSPA/WCDMA:
900/2100MHz
Up to 2 Mbps upload and 7.2 Mbps download speeds
GSM:
850/900/1800/1900MHz
(Band frequency, HSPA availability, and data speed are operator dependent.)
Which is apparently compatible with T-mobile. Well whenever I try and connect it says it fails and gives me and error message:
"SIM card not provisioned MM2"
After doing some google searches on that I found that it may mean you need to replace your sim etc. I've tried 2 different T-mobile SIMS and they both failed. Yet they both work in the T-mobile phones.
If anyone knows a work around to get me past this crap I would GREATLY appreciate it. It's been turned into an all day project and I'm nearing a tired and disappointing end.
Also info that may help:
-Neither of the SIMS currently have minutes on them but are both still activated under the owners names and display signals on the T-mobile devices.
- My HTC aria IS unlocked and IS rooted/loaded with a custom rom
-I can locate the 2 networks available in my region when I click on search for networks in my "wireless/network settings"
If you need anymore info to help answer the question please let me know and I will provide it as soon as I am able.
The phone is fine. It may be because you don't have minutes on the plan, or because the SIM card is too old or something. I'd suggest going into a T-Mobile store and getting it squared away.
Yes after several hours of hunting I was able to find someone who had the same problem. Apparently whether the SIM gets signal or not from the device it came from it will give you an error on the device you put it in until the SIM has actual minutes on it. The guy had said on his post he tried around 3 different cards and all had the same effect.
Sorry for the double post just wanted to update.
The reason I wasn't able to get signal on the phone was because the T-mobile sim card I was using was an un-paid Flex Pay SIM card with T-mobile. The actual prepaid SIM (which im using now) gets a signal even when there aren't minutes on the device so you can add funds to your account through the mobile phone.
I just flew in to Spain for study abroad here for the next 4 months and wanted to take my ATT Atrix along for the ride. So I called ATT, got the unlock code from them, and after much difficulty and having to flash a Brazil Radio to negate the maximum number of tries limit, I got it carrier unlocked. The SIM I am using now is a prepaid Yoigo card (funny name, i know). I also reflashed the .36P radio.
The weird thing is that Onavo Count still says I am roaming, even though I have a local SIM in Barcelona. Is this an issue with Onavo Count? Or is the phone really still thinking it's roaming? Is it the radio? After every reboot, the phone makes me enter the SIM Pin. Is that an issue with the sim card and the phone getting along, or just the standard SIM security feature doing it's job.
Im running cm7 rc1 with the .36P radio.
Thanks in advance.
Anyway to activate 3G? Phone won't work on AT&T's 4G LTE. Only works on 3G !
AT&T says they have an LTE problem. My phone is the only one out of 4 on the
same acct. (all LTE) that doesn't work. Crazy!
Already had a Galaxy S3 I747 that did the same thing. No VM or rec'd a few hours
later & no Texts (but if I have texts out there not rec'd., I can send myself a text & everything
comes in) all of this on 4g & sporadic receipt of calls. AT&T says its a system problem not the phone.
AT&T put the phone on 3G it works, but their system keeps tossing it back to 4g LTE! AT&T no fix for it yet.

Do you have an LTE sim card?
Check your APN setting. It should be "pta" for access point name.
At&t LTE isn't a complete network. There's only one tower in my area that is LTE. And they do have system problems that can last for days.
Good question on the SIM Card. It has no identifying markings on it, as in the old cards used to have 3G on them. It looks like the old AT&T SIM CARD. If the LTE is the smaller SIM card, the answer is no.
My Galaxy S3 had the smaller card & still had the same problems. Right now (in settings... Mobile Network type) the phone jumps from UMTS
to HSPA:11 yet my wife's S2 reads LTE & no problems. Any phones out there that have the option of turning off 4G LTE besides the IPHONE?
APN is pta & problems since NOV. but just found out end of March it is an LTE problem after I began to contact the ppl at the top of the ladder at AT&T. Techs that I spoke with don't have a clue!
What I can't figure out is why out of 4 phones on the plan, I'm the only one with problems. If it were "just" a system problem it would logically affect all phones. Yet AT&T says it's an anomally with my line.
Wondering if another phone & new number would rectify it? lol
Try sim card swapping with a phone that reaches LTE network.
I am here in Singapore with my Verizon Galaxy S4 and it is indeed unlocked, however, there's a small issue.
I picked up a pre-paid SIM card from Singtel. Inserted into the phone, was able to add the APN information. Get to the last step that says dial *363 to activate the SIM card and that's where the wheels fell off the wagon. Every time I dialed *363 (per the instructions on the SIM card) the phone kept coming back with an Invalid MMI code..
Eventually, the only way to activate the SIM card was to have the SingTel put the SIM in his phone and do the *363 to go through the process.
Anyone else experience something similar with a pre-paid SIM over seas?
I did not have this problem. I am using a prepaid SIM in europe (T-mobile de). I had to set the phone to GSM (or global), enter the APN info, and then dial the activation number. It all went well, without problems.

I wonder if it is the MMI code that SingTel uses. Anyway, definitely doesn't work for Singapore.
My mother uses an Honor 5X with a US/Mexico roaming contract plan on AT&T for calls, and a Mexican data SIM while while living in Mexico. She is currently visiting the US and we swapped out the Mexican SIM for an AT&T go phone sim. This set up fine and worked for a day or so, after which she left my house to visit elsewhere. The next day after leaving her contract line stopped working. After consulting with an AT&T store rep, they diagnosed that the old AT&T SIM was bad and gave her a new one. She thinks, but is not sure, that in the store both lines were working, but within minutes after leaving, the contract line displayed "emergency calls only". For the next week and a half, this continued and though she occasionally received calls on her contract line, she has not been able to make calls from it. The go phone line has worked as expected (though reception was spotty when other AT&T phones had full bars at the same location.) I do not recommend that service even for occasional use, it seems definitely deprioritized.
My question is this, is it expected that 2 SIMS from the same carrier would not work at the same time in this, or any, dual sim phone? This doesn't make sense to me since each SIM has its one IMIE. Each line should be treated as a separate device.
FYI disabling the go phone SIM entirely will enable full service on the contract SIM within a minute or so. Once the gophone SIM is enabled again, the contract SIM displays "emergency call only" within a few seconds.
Thanks for your input.
theres nothing like two same sims doesnt work and all,,
its better you get it to the service center
