Can't Connect to AT&T Network.

My Captivate can read the SIM Card, but I can't connect to the AT&T service.
I go to Settings > Wireless & Network > Mobile Netoworks > Network Operators > And select AT&T, but it says "Your SIM card does not allow a connection to this network."
On Perception 9.5, When I do the same thing, It says "Unable to connect. Try again later."
I flashed other ROMs and they all do the same thing.
Help?

Are you using an AT&T sim that has a data plan enabled?

Yep. 3G, Calling and SMS was all working before.

Have you manually checked the apn settings?

Did you flash a new rom recently? Maybe the modem isn't playing nice.
If nothing else, go get a new sim from the local store and see if that fixes it.

Yeah, I flashed multiple roms (Perception, Doc's, Darky, GingerClone...). They all do the same thing.
I guess I will just head over to AT&T and get a new SIM.

[Q] Lost 3G AT&T service after traveling overseas

While traveling overseas in Malaysia I bought a pay-as-you-go SIM card and got phone and 3G service for a week. Worked great!
Now that I'm back in the states I have no 3G service with AT&T.
What do I have to do to get my phone back to 3G service? I can call and text just fine. Wifi is fine too.
I've looked for a FAQ please point me to one if it exists.
I'm running Cognition 3.02. Probably more info is needed. If so please let me know.
Thanks,
Gary

Solved!

Surely at&t has the settings written on there website some where. Search there. Otherwise call them or the store witch you got it from.

I have similar problems using Telstra in Australia. The phone just don't want to go into LTE mode. I am using Wanam ROM if that has anything to do with it.

[Q] Not getting MMS/data - APN issue?

Hi everyone, I have an AT&T Moto X that hasn't been able to send or receive multimedia messages, and the data connection doesn't work. From what I've read, I believe it's an APN issue. However, I'm hesitant to mess with the settings because it's still on a basic phone plan, with no data. When I upgraded to the X, AT&T never automatically added a data plan. If possible, I really want to keep it this way, as I have no need for data, but would like to get MMS working.
In this thread (http://forum.xda-developers.com/showthread.php?t=2238660) post #4 says to leave APN Type set to "phone" if you don't have an LTE plan. Is this a way to make MMS work, but not data? Is there a way to do this at all? And can that be done without AT&T recognizing the smartphone and adding a data plan? Any replies are appreciated :highfive:

You need some sort of data to download multimedia. Does it work with Wifi?

You mean a data connection, not plan, right? It doesn't work over wifi. From what I've read, only Sprint allows downloading MMS over wifi, not AT&T.

I have the same problem, data just all of a sudden quit working and I had an LTE connection with no problems since I got the phone in November, same APN's as you on my phone and both always worked. I now get nothing no 2G, 3G, HSPA+ or LTE. SMS and calls still work but no MMS as expected since it requires a data connection. Spent 2 hours with AT&T both online and in store trying to see if it was anything on their end. Tried every APN they could find for the MotoX, about 4 or 5 different ones they came up with, even tried a new SIM card and still nothing. I did a factory reset last night in desperation and still no data so I finally RMA'd the phone with Motorolla tech support and the new (refurbished) one should arrive tomorrow. We'll see if that fixes it.

You had to send it back? Oh wow. Please post an update when you get your new phone or get it figured out. Thanks for the response!!

Not sure if this is the issue, but AT&T's own site says that the MMSC url should be: http://mmsc.cingular.com
You may give that a shot.
Additionally, from what I understand, MMS is ONLY transmitted through either EDGE, HSPA, HSPA+, or LTE
If you don't have data at all, I'm not sure if you can even send or receive MMS.
Good Luck

Time for a very late update, in case anyone else has this issue. I did finally get my data working, using the 3G APN settings on this page: (first result when you google "att apn settings", I can't post links yet)
Now, I mentioned in my first post that I really only wanted mms, so what I did was make two new APNs - one a copy of my original, non-working APN, but with APN type changed to only "default", and I selected this one. The second APN is the settings from the link above, but with APN type changed to only "mms". So now when I have data turned on, only mms works, not any other mobile data. AT&T still hasn't recognized the smartphone on the account and thus hasn't forced me to add a data plan.

Please Help. SM-N960U Factory Unlocked - No MMS - APN won't stick

**Reset Network Settings leaves the APS Settings blank**
I have an SM-N960U (factory unlocked) running Android 10. I am using a Red Pocket CDMA-V sim card. At first, the phone wouldn't register Verizon. It was stuck in T-Mobile. Replaced the Sim card and it registered to Verizon, but still no MMS. Everything works - Voice, SMS, Internet/Data - Just won't send or receive MMS. Red Pocket keeps re-provisioning/registering my device and sim, and still no MMS.
Every time I add a new APN Setting, I lose voice, data,and sms. (I've never gotten MMS working)
Red Pocket says that even though the phone is factory unlocked, it may not be a "Verizon Registered Device." Huh?? I touched bases with Verizon, but they had never heard of such a thing. Anyway, I'm stuck with this phone while my other Note gets a new screen installed, and I need MMS for work.
Here are the two APN Settings we've tried. The first one, I found on my own. The second one, came directly from red Pocket Customer Service. Neither worked for MMS.
1) I found this one online. No MMS.
