Not able to make calls since 3G shut down with my 4G LTE Phone
I'm not able to make calls on my Android phone even though it's showing connected to 4G LTE. My phone is on the approved list issued last year (BlackBerry KeyOne BBB100-1) and since 2/22/2022 I've not been able to make/receive phone calls. Data and texting work fine. I've spent over an hour with tech support 3 different times doing a million different things with zero resolution. (Each time I'm told someone will contact me within 48 hours - never happened) I'm at a desperate point and deeply disappointed that AT&T isn't getting back with me as promised.
Maybe someone on here can help?
