Based on the information, I am suspecting it is APN issue. What is the right APN for AT&T network in USA?


#2

NEXGENPHONE is the name of the APN for ATT. That fixed the issue.

I thought I would post what I did. I just used the APN name phone and it seems to be working. I got this output for cm data:
