iPhone showing ‘SOS only’ - what does that mean?

Users said their cell signal wasn't working, and their screen only showed the 'SOS only' tab where it would usually show their cellular connection.

This means the device isn't connected to a network and users can only use their phone to make emergency calls. 

Which areas are most affected?

Outages were reported in many major U.S. cities, including New York, Los Angeles, Atlanta, Tampa, Dallas, and Philadelphia. 

Other networks, including Verizon and T-Mobile, showed outages on Downdetector, but AT&T users reported the most. 

What has AT&T said on the outages? 

AT&T issued the following statement: "Some of our customers are experiencing wireless service interruptions this morning. Our network teams took immediate action and so far three-quarters of our network has been restored. We are working as quickly as possible to restore service to remaining customers."
