anyone have this problem?
iphone could not activate cellular data network?
i cant get on internet, check mail or anything unless connected to wifi. I only had this phone about 2 weeks...i tried resetting the network connections and the iphone its self and still doesnt work?
Would this be a problem with att or just my phone?

 

I've never had that problem... did it just suddenly stop working or did something happen to it that you know of?

 

It's quite common. I find it generally happens when the signal is lost. Try rebooting the phone if the problem persists and that should take care of it. Try turning wifi off as well.

 

Have it happen occassionallly on me. Just restart your phone and you should be golden.

 

it works this morning. i previously tried restarting it and resetting all the network connections...must have been something att was doing with their towers?

 

Every so often mine will start acting goofy or not want to connect to the internet. I just turn it off and then back on again and it works great after that.
