Do I need to sign up to receive warning messages on my phone?

No. You do not need to register to receive warning messages sent through Emergency Alert.

Emergency services can use Emergency Alert to send a warning message to mobile telephones based on the last known location of the handset and to all telephones based on registered service addresses.

It is important that the registered service address of your mobile telephone is up to date. You can update your registered service address with your telephone service provider.
