If you're seeing SOS mode on your phone today, you're not alone. Verizon, the largest wireless carrier in America, is experiencing a massive outage that's affecting users across the US. Around 10 a.m. ET, users reported that they could not call, text, or use cellular data. Many added that their phones were in SOS mode.

A widespread Verizon outage is causing iPhones and Android devices to enter SOS mode, preventing them from making mobile calls unless they use WiFi calling.
