How does the system work for mobile phones?

There are two ways the Emergency Alert system works for mobile telephones within a geographical area affected by an emergency:

  • a┬átext message is sent based on the registered service address of the mobile telephone
  • a text message is sent based on the last known location of the handset at the time of the emergency. This includes visitors and people travelling in the area.

Based on how mobile telephone coverage works, you may receive a text message if you are outside the area of risk but you are nearby that area. It is important that you read the message carefully and understand what action you may need to take.

If you do not know the network that your mobile telephone uses, you should contact your service provider.
