When iPhones aren’t connected to a cellular network, they will typically alert the user by giving an indication in the phone’s status bar. Those notifications usually say “No Service” or “Searching,” but your phone may also say “SOS” or “SOS only.”

Verizon said some of its wireless services were down Wednesday, leaving many customers without access to voice and data services.

On X, a Verizon support account suggested that customers may receive a discount on their phone bill based on the outage.
