Starting this morning I can't call anyone, from my iPhone XS (xFinity Mobile).
Every time I try to call, a voice tells me “You have reached nonworking number, announcement ...”
Also, nobody can reach me.
The signal on my phone is full, internet working fine.
I tried to power off, remove SIM, wait for 15 sec, insert SIM, power on - nothing!
I tried to reset network settings - nothing!
Chatted with xFinity Mobile Support Team more than an hour - nothing!
