T-Mobile has officially launched the ‘T-Mobile Personal CellSpot router,’ a new device that is available, “at no extra charge whatsoever for qualifying customers with a $25 refundable deposit,” according to the company’s promotions.

You can get a Personal CellSpot sent to you just by dropping into a T-Mobile store or calling Customer Care – as long as you have a high-speed broadband connection and a Wi-Fi calling capable smartphone. The Personal CellSpot is like a T-Mobile tower in your house, built on proven Wi-Fi technology. Get a “full-bars” T-Mobile experience wherever you choose even beyond the reach of any cellular network.

The Un-carrier is also extending its coverage to the skies with the launch of free Gogo in-flight texting starting today. Through this exclusive partnership with Gogo, T-Mobile customers will be able to send and receive unlimited text and picture messages, and even get visual voicemail, on any Gogo-equipped flight on U.S.-based airlines – which is more than 75% of domestic flights carrying close to 300 million people last year.
