AT&T Public Notice: Temporary AT&T Service Disruption
AT&T will be performing planned maintenance on a local cell tower from March 13 to March 17 which may impact service in our area. During this time, AT&T customers may experience reduced coverage or have their phones go into SOS mode.
When your phone displays SOS or SOS only, it means your device has lost a regular network connection but can still make emergency calls (911) using any available network.
We recommend planning ahead for potential service disruptions and using Wi-Fi for calls and messaging when possible. Thank you for your patience as this maintenance is completed
