Hot on the heels of some downtime for Google Docs earlier today, it looks like AT&T’s network is experiencing some trouble. People have taken to social media to ask Ma Bell why they can’t place calls, but AT&T’s solution is to restart your phone. The tweet that addresses the issue doesn’t say why the network is having issues or why restarting your phone will help.
If you've experienced an issue when making wireless calls, please restart your device, this might be required multiple times- that should resolve the issue.

Putting on airplane mode for a couple minutes then back off worked for me and seems to be working for a lot others ??
