It’s only a test of the Wireless Emergency Alerts system by Big Brother, specifically NYC’s Office of Emergency Management, the FCC, and the Department of Homeland Security. Between 10AM and 3PM, text messages that read “Severe Alert” or “Extreme Alert,” will be sent to random AT&T, Sprint, T-Mobile, or Verizon customers. There’s no opting out, thanks Congress, so think of it as the mobile version of those piercing emergency messages that unapologetically bombard your TV.
