AT&T working to restore cell service across the country including Illinois

Customers of AT&T, the country’s largest wireless provider, are reporting widespread outages. Some iPhone users saw SOS messages displayed in the status bar on their cellphones. The message indicates that the device is having trouble connecting to their cellular provider’s network. That can be a big problem in an emergency. AT&T urged customers to connect to Wi-Fi to use their phones. “Some of our customers are experiencing wireless service interruptions this morning. We are working urgently to restore service to them. We encourage the use of Wi-Fi calling until service is restored,” AT&T said in a statement.
