ZenFone 6 will not make or receive calls
My ZenFone 6 (AT&T USA) will not make or receive calls. Texts work fine. The phone updated to Android 10 last week and I was able to make calls. I turned wifi off and was able to make one call but now it doesn't call or get calls no matter what I do.
I restarted the phone multiple times and reset wifi,mobile,& bluetooth via Reset options, this did nothing.
The phone is not in Airplane mode.
Firmware version is: 17.1810.2009.176
The phone is not rooted
