Why can’t I make calls?

Hello @caroline, we are here to help you with your phone calls.

Try these tips to help get your phone working again: 

• Make sure your software’s up to date.
• Confirm you have wireless service. Check our network coverage map.
• Turn off Call Forwarding . ~ Press #21# on your phone and then the Call, Send, Talk, or Receiver key.
• Check that you aren't blocking calls. 
• Check your account to make sure your service isn't suspended. If it is, you'll need to pay the full past due to restore service. 

Try our AT&T Troubleshoot & Resolve, select your device from the list, and then choose Phone Calls under Service/network issues.

Please let us know how this information helps!
