S21 hangs up after one or no rings

[Milajoyw]

I’ve tried to call 8 different people today. Some local. Some long distance. After it either rings once or not even once the phone disconnects. I cannot make any calls. Please help.

Exactly the same problem here. I think it's a problem on the West Coast. I'm out west.

Good afternoon, Milajoyw! We are concerned to hear you are not able to make calls, and we would love the opportunity to help you today! Can you please elaborate more? When did this issue start? What is your zip code?
