I have powered off and back on and it's still doing the same thing. I have an unlimited data plan, but cannot get onto the internet either. However, I can connect to the wifi at my work and am receiving emails and can get online. Still cannot text, make or receive calls.
Were you able to resolve this issue? Mine did the exact same thing 3 weeks ago. Took it into the Diamond Wireless Premier Provider Kiosk where I had purchased and signed up...after powering down, going to plane mode and trying a reset - nothing happened. They sent a new one to me and alas after another week...same thing. They're sending another one - I'm tired of this happening.
