At approximately 2:20PM ET, FEMA conducted a test of both the Emergency Alert System (EAS) and the Wireless Emergency Alerts (WEA) covering radio, TV broadcasts, and mobile devices in the US, but you might not see it on your phone. That’s because this time around, unlike the Presidential Alert test in 2018, it only reached phones with a setting to receive test messages and by default, most phones are set to opt-out.
According to this document (PDF) from the FCC, on Android phones, there should be a Wireless Emergency Alerts section in your settings menu with an option for “State/Local Test alerts” that you can turn on or off. The process described for iOS is more complicated, but Apple’s support page explains how you can opt-in:
Open the Phone app and tap Keypad.
To turn it on: Enter *5005*25371# and tap the green phone icon. You’ll get an alert that says “Test alerts enabled.”
To turn it off: Enter *5005*25370# and tap the green phone icon. You’ll get an alert that says “Test alerts disabled.”
This year's Wireless Emergency Alert (WEA) test messages will only be displayed on wireless handsets where subscribers have “opted-in” to receive them. This will allow for a nationwide test without disturbing the public.— National Weather Service (@NWS) August 9, 2021

If you missed it, or if you weren’t thirsty enough to opt-in, this is the message for mobile devices:
“THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed.”
Update (2:30PM ET): Updated to reflect that the test occurred.
