Cannot initiate or receive calls on oneplus-fajita with AT&T in United States
LTE data and text messages work fine, but the device is unable to initiate or receive phone calls when connected to AT&T's U.S. network (NXTGENPHONE
APN). GNOME Calls immediately displays "call ended" as soon as a number is dialed, and I am not alerted to any incoming calls.
