Xperia P on AT&T - Sony Xperia P, U, Sola, Go

I just got my xperia p and I realized that it can't download the internet setting for AT&T so that i cant connect my P to AT&T 3g network. I can make call but no internet. I found the way to manual setup APNs and I can connect to internet now but no MMS... Anyone here please help me....

You need to manually input MMS settings.
I'm surprised it didn't download internet settings. Go to WI-FI, then hit download settings. That might work.

*EDIT* Your APN settings worked flawlessly. Every other APN settings I found on the internet (I've tried maybe 5 or 6 different versions, with different "APN Types", leaving some Proxies blank, etc.) made my data freeze. This one works flawlessly... thanks so much!
Thanks for the APN setting details!
Just wondering since there's not many people using the Xperia P on AT&T. Are you using the LT22i or the LT22a version? I have the LT22i and I keep on getting disconnected from the network, and a reboot becomes my only option to reconnect to the network (both calling and data). Pretty annoying, as it happens multiple times a day. Xperia Support told me that it's because my phone isn't made for the AT&T network, but the frequency bands match up so I'm not sure about what they say.

I thought your APN settings fixed it, but once a day (mostly at night) I get disconnected from the network and can't reconnect until I reboot. Oddly, my signal strength is frozen at full strength with the "H" (but no arrows going up or down).
Can I ask what firmware you have? I flashed my LT22i with a generic ICS rom from central europe. I don't know if that'll make any difference. If you have no problems, I'd just like to have basically the same exact phone as you, haha.
Thanks!!!!

I also got my Xperia P today, but when I put in my micro sim card, I don't get anything? I cant even make or recieve calls or do anything, it's not reading it at all. After an hour or so i briefly got Edge network for about 5 minutes but then it went away again. Did you play around with your settings at all?

Did you see what was posted earlier? Go to this thread: http://forum.xda-developers.com/showthread.php?p=27982934 and use the apn settings I listed. Once you setup BOTH of those restart your phone. Should wwork after that. Yes add both the apns just like I listed. Added them below for you. I use this on my Xperia S and Xperia P on AT&T. Data, calls and mms/sms work fine.

I am using these settings, and it still doesn't do anything? Under the APNs, when it shoes the Phone settings, and ATT settings, are they both supposed to have a blue dot to the right of them? only the phone does. And for the ATT settings, The APN enable/disable is highlighted enabled, and not on the phone settings, does this have anything to do with it? Also is it supposed to be on the wcdma/gsm network, or just gsm netowrk? Thank you so much for the help!

Everything matches up perfectly, but still no luck. I'm going to the att store to see if I have a faulty sim card, it's the only other reason I can think of. For your att plan tho, which phone do they have you using on there since they dont have the xperia p?
