Here’s Why Your Phone Could Buzz at the National Mall Saturday

If you have your cell phone with you near the National Mall Saturday morning, you might hear a loud — and totally harmless — buzzing noise.

The District of Columbia is conducting a Wireless Emergency Alert Test between 11-11:30 a.m. Saturday, D.C. Homeland Security said in a tweet.

Cell phones and mobile devices on or near the National Mall will buzz loudly and receive a test message that reads: “A test of the District of Columbia Wireless Emergency Alerts System. No action required.” Since it’s only a test, there’s no cause for alarm.

D.C. Homeland Security occasionally tests public alert and warning systems to make sure its alert system is working properly. That way, it can deliver urgent alerts and warnings to the public about missing children, dangerous weather or other emergencies.
