When wildfires, tornadoes, and other public-safety emergencies strike, MetroPCS customers will soon be able to receive government alerts on their mobile phones. The network operator is the latest to announce it will use the affordable, hosted Commercial Mobile Service Provider (CMSP) Gateway from Interop Technologies to deliver the Commercial Mobile Alert System (CMAS) alerts when they become available in 2012. Bluegrass Cellular of Kentucky announced earlier this month that it also will rely on the hosted Interop gateway to provide CMAS service.
