Under a header that'll read "Presidential Alert", the text will read, "THIS IS A TEST of the National Wireless Emergency Alert System".
A test of the Wireless Emergency Alert System's government alert feature will take place at 2:18 p.m. October 3.
Emergency officials sending out an alert about a pending disaster need only issue one alert with the IPAWS technology. Some older phones, however, may not receive the alerts.
Many cellphone users receive alerts now - Amber Alerts for missing children, and flash flood or tornado warnings. This alert is just a test of a national presidential alert system, which will be used in the future in only dire circumstances, such as a missile launched by another country at the USA, reported CBS News.
Despite being called a "Presidential Level Alert" emergency messages sent through the system won't be written by Donald Trump or any other president.
The EAS test is expected to follow at 2:20 p.m. This will be a test of the country's wireless emergency alerting system.
The Federal Emergency Management Agency says it'll sound like an Amber Alert or flood warning.
Asked about the possibility that the government's messages could pour into people's phones like Trump's tweets, FEMA official Antwane Johnson said that wouldn't happen.
The Federal Emergency Management Agency (FEMA) and the Federal Communications Commission (FCC) is coordinating the alert. They said a person on a call lasting 30 minutes may not get the alert as with phones with an active data connection. Instead, they're from the USA government, and both are test messages.
For the WEA alert, you'll get a push alert (pop-up message box) on your phone, and the alert will also include a tone and vibration. It is similar to monthly tests of the system the public is accustomed to hearing.
