AT&T, Verizon and T-Mobile customers began experiencing the problem around 3 a.m., according to the Down Detector website—which provides real-time outage reports.

What else?
Mobile phone users with iPhones are seeing "SOS" in their phone status rather than the usual "5G." According to the Apple Support website, this means the device isn't connected to a cellular network but can still make emergency calls to 911.
The AT&T, Verizon and T-Mobile websites all have guides to help customers turn on Wi-Fi calling in instances such as this.
