Beginning today, T-Mobile customers will be able to purchase Tile, a Bluetooth tracker and app for smartphones, in the carrier’s retail locations.

Now in its second generation of hardware, Tile will come with a corresponding app upgrade that will allow users to find their misplaced smartphone or device from their physical Tile, any smart device (Android or iOS), or a web app.

“We aim to help our global community of customers never lose anything ever again,” said Tile co-founder and CEO Mike Farley. “Knowing that a cell phone is misplaced every 3.5 seconds, we created Find Your Phone, a solution that lives up to the experience our community members already know and love – it’s simple, intuitive, and most importantly, effective. We are thrilled to expand the Tile community to include T-Mobile.”

The latest generation of Tile hardware produces a louder alert than its predecessor, and an upgrade to the app allows users to turn their Android and iOS devices into Tiles themselves, complete with the ability to ring the phone or see its location on a map.

Until this point, Tile has only been available for purchase online. The company says that more than two million of the trackers have been shipped since launch.

“We start with revolutionary Un-carrier benefits and plans, and add the hottest devices and accessories to deliver what customers want in wireless,” said T-Mobile’s chief marketing officer Andrew Sherrard. “So it makes sense for T-Mobile to be the first to offer Tile in retail stores and give customers a totally new and incredibly cool way to keep track of their mobile lives.”
