Cellphone users can not opt out of the test, which uses the same special tone and vibration as AMBER alerts and tornado warnings. WEA may also be referred to as "government alerts" or "emergency alerts".

For the first time ever on Wednesday, Americans nationwide will receive an alert on their cell phones from President Trump. Verizon, T-Mobile, AT&T, and Sprint all participate in the program, so you'll likely get the test message.
Wireless phones should receive the message only once.
The WEA test will be broadcast over the course of about 30 minutes and sound the same as an AMBER Alert. FEMA says users can not opt out of receiving Wireless Emergency Alerts. In a real emergency, a FEMA official using a device "very similar to a laptop computer" will receive information from multiple federal agencies and the White House, and select one of several pre-written messages and update it to fit the circumstances. "No action is required".
WEA is used to warn the public about risky weather, missing children, and other regionally critical situations through alerts on cellular phones. This test will be heard on cell phones, radio, television, and cable systems, satellite radio and television providers, and wireline video providers.
