After the recent tsunami advisory emergency alerts, some phone users reported that the alert vanished after they had seen it. It’s important to know that, while the alert doesn’t stay in your text message list, you can always find the message again if you need to check the details.
For android users
Emergency alerts are usually found in your Messages app settings. Go to the Messages app, then ‘settings’ (three dots or wheel) and select ‘emergency alert history’. If this doesn’t work on your phone, go to the Messages app, select your account (the circle on the top right), select ‘settings’, select ‘advanced’ and select ‘wireless emergency alerts’.
For iPhone users
The alerts will be in your notifications. Access your notifications by swiping down from the top of your screen. Be aware that if you delete your notifications, you will also delete the alert.
