T-Mobile is adding the BlackBerry Classic to its lineup as part of its latest plan to conquer the business world. On Thursday, the two companies announced that the phone would be available on T-Mobile's website starting May 13 and at participating U.S. T-Mobile stores starting May 15. Under T-Mobile's installment plan, the BlackBerry Classic will sell for $0 down and $18.33 a month for 24 months.

In 2013, T-Mobile announced that it would no longer stock BlackBerry devices at its retail stores due to slow sales. In 2014, BlackBerry announced that it would no longer sell devices with T-Mobile following a T-Mobile e-mail campaign that encouraged BlackBerry customers to switch to an iPhone.

The BlackBerry Classic itself has already been available at Verizon and AT&T.

The BlackBerry Classic is powered by a 1.5GHz dual-core processor and has 16GB of internal storage, which could expended by using a microSD card (128GB max). It has a a 3.5-inch HD display made of Corning Gorilla Glass 3, which can be further increased to 128GB through a microSD card. It has a physical QWERTY keyboard.
