Yup. Happened at 3:30 am this morning. I went to AT&T store this morning. It’s nationwide: AT&T, Verizon T-Mobile, all affected. 90% of the network is back. In was advised to turn on Wi-Fi calling. All good now as my 5G+ is back.
Wifi calling is a device by device basis with ATT, which is dumb.
I can confirm on Verizon, I had 0 issues. I know some other people who were on Spectrum mobile, Verizon and had no issues. Based on the traffic on twitter, it was mostly ATT and the companies that use their towers.
