When a T-Mobile subscriber finds himself unable to connect to a cellular network, he gets connected to his carrier’s satellite service in order to maintain a wireless connection. Over hundreds of thousands of smartphone users have signed up to try the service which allows one to stay in touch during an emergency that prevents cellular networks from operating. When the cell networks go down, or you find yourself in a dead zone with no connectivity, your phone will automatically connect to the satellite network allowing you to at first send texts to users. Eventually, the service will allow calls, texts, and data to be connected via satellite in dead zones throughout the country.

Despite what would appear to be good news from T-Mobile, the Q1 report didn’t completely please Wall Street, It seems that analysts who follow T-Mobile expected it to report more new phone customers in the quarter. As a result, for the week T-Mobile shares declined $28.23 or more than 10.82% to close Friday at $232.77.
