I got a Sony Xperia Z from India to use in America with my At&t service.
I can receive calls and simple text message. I am not able to receive any pictures.
I can only use internet with wifi.
I installed the internest setting for att and it still is not working.
Please help...
First make sure that data is enabled in the notification bar settings.
AT&T seems to have different settings depending on what plan you use. I recommend that you contact AT&T to check what APN-settings you need and that you then enter them manually under Settings -> More -> Mobile networks -> Access Point Names.
If you have the LTE-version of Xperia Z and your plan doesn't support LTE you may also need to select WCDMA/GSM under Settings -> More -> Mobile networks -> Network mode.
Hi Rick,
I have tried all those things and nothing worked?
Any other suggestions?
Does the C6602 model work in the us?
The c6602 doesnt support lte but i think it should work in the us
You have to contact at&t customer support only they can help you on this
This is why before buying a phone from another country you should first consult with your network provider
And in the us xperia z hasnt yet arrived on contract the carriers, but i read somewhere a new model c6606 is coming on t-mobile. People who have purchased the c6603 models from amazon are having problems with at&t, just read the reviews on amazon
Yes, the C6602 model works in the US. I'm using it with T-Mobile.
I also posted this in response to someone else earlier...when I put my SIM card in (again, I'm with T-Mobile), data wasn't working. I went to settings > Xperia > Internet settings and then clicked accept. Make sure you're connected to Wifi to do this. Internet and MMS started working after the download.
I know this is a couple weeks later but hope it helps. 
C6603 work just fine with ATT
as for apn settings
Name: pta
APN phone
MMSC: http://mmsc.mobile.att.net
MMS proxy: proxy.mobile.att.net
MMS port: 80
MCC: 310
MNC: 410
Authentication type: None

H and H+ should work
this settings worked for a while, some minutes, then the phone stopped working with AT&T data... that's very strange!
