Emergency alerts are sent out via the mobile telephone network, to all mobile telephones in a defined area.

Alerts will be received and displayed on mobile telephones that are:

  • Switched on
  • Connected to the mobile telephone network (4G/5G)
  • Compatible (updated with required software) to receive Emergency Alert

The text in the warning will be in Norwegian or English, depending on the language settings on your phone.
