USD-Owned Cell Phone or WiFi Hotspot Not Working

Issue/Question

My USD cell phone cannot connect to the network anymore. I tried a different SIM card and the phone worked just fine which shows it is a SIM card or AT&T issue and not a phone issue. Under Settings/General/About/Network it shows:
Not Available and Sim not provisioned

My hotspot is saying there is no service

Environment

• USD-owned cell phone
• USD-owned Wifi Hotspot

Cause

Possible bad SIM card
