A widespread Verizon outage hit mobile phone customers across California and the U.S. on Monday, limiting some residents to emergency phone calls, so-called SOS mode. Downdetector, a website that crowd-sources reports of such disruptions, showed hundreds of customers in the Sacramento area began reporting outages around 7 a.m.

Verizon and AT&T customers have reported their phones being stuck in SOS mode due to what appears to be a widespread outage.

Verizon users are in the midst of a major disruption, as a massive nationwide outage has left millions disconnected. Whether you're working remotely, attending virtual classes, or just trying to get through Monday with a functioning phone, Verizon's widespread network failure has thrown a wrench in the day for many.
