More than 200 million US mobile phones have received a test “Presidential Alert” text notification. The trial text message is designed to check that a previously unused emergency communications system works properly.
The test text message in the USA was sent by the Federal Emergency Management Agency (Fema), which would also be in direct control of the system if a real alert was ordered by the US President, Donald Trump.
It is intended to be used to warn of major threats, including:
- missile attacks
- acts of terrorism
- natural disasters
📳 TODAY (10/3): At 2:18 PM EDT, we will be testing the Wireless Emergency Alert system nationwide. Expect a message box on your phone along with a loud tone and vibration.
