call ATT, mine did this same problem, and it for some reason got kicked off in the ATT system that i didnt have the correct messaging plan anymore. it sounds odd, but it fixed mine. good luck!

you may try a master reset after backing up to your PC if that doesnt work.

Hope this helps! pls dont forget to rate the solution!

SOURCE: cant receive picture texts

Hi to send and recive picture texts you will need to contact your network service provider and get them to send the MMS settings and GPRS settings to your handset, without these settings saved to your phone you will not be able to recive the picture texts, hope this helps.

U SHOULD NEED MMS SETTING

I was able to unlock the phone and use the net. You have to change the settings in the connection menu. Go to the GPRS option and put in the following:
Connects to:
Internet
Access point:
wap.cingular
User name:
WAP.CINGULAR.COM (All caps)
Password:
Cingular1
Primary DNS:
Leave blank
Secondary DNS
Leave Blank

Make sure you change the name from T-Mobile Data to Media Net that is the service AT&T uses. The only thing you will not be able to do is send picture messages. I am still looking into how to fix that issue. If you call AT&T technical they are going to tell you that you can not change the settings just so that you will buy a phone from them.
