The test alert was delivered via the Starlink satellites in a process that took seconds, says T-Mobile, which is preparing to launch a cellular satellite system with SpaceX this fall.

PT on Thursday, September 5th, T-Mobile initiated a test alert for a hypothetical evacuation notice,” according to T-Mobile. “The alert was sent 217 miles into space where it was received by one of the more than 175 Starlink direct-to-smartphone satellites currently in low earth orbit that effectively function as cell towers in space.

T-Mobile successfully sent the first-ever satellite-based emergency alert in the US, aiming to provide critical alerts in remote regions.

T-Mobile sent and received the first-ever wireless emergency alert (WEA) with the help of SpaceX's Starlink satellites earlier this month.

T-Mobile and SpaceX have successfully tested a wireless emergency alert (WEA) via the Starlink network's new direct-to-cell capability. The test message was sent by emergency operators and received by a Starlink direct-to-smartphone satellite currently in low earth orbit.

T-Mobile partnered with SpaceX to deliver a the first successful wireless emergency alert in the U.S. without Earth-based cell towers

T-Mobile used a satellite network to issue emergency alerts to users in areas with little to no signal. Here's why it's such a big deal.The Latest Tech News, Delivered to Your Inbox

T-Mobile and Starlink team up on the first emergency alert via satellite, enabling delivery to areas with no cell service

In a bid to revolutionize coverage of catastrophic events, wireless emergency alerts will soon be more reliable, regardless of coverage zones. Hurricanes, tornadoes, and fires will no longer disrupt US citizen’s access to critical information.
