13th December - Samsung Telecommunications America (Samsung) and T-Mobile USA, Inc. (T-Mobile), today announced the availability of the new Samsung Katalystâ„¢(a). The Katalyst adds a stylish, slider design to the growing line-up of phones that support T-Mobile HotSpot @HomeSM service.

With built-in support for T-Mobile HotSpot @Home, the Samsung Katalyst provides customers with great wireless coverage when placing calls over a home Wi-Fi network and at nearly 8,500 T-Mobile® HotSpot locations nationwide. When customers leave home or a T-Mobile HotSpot, their calls are passed onto T-Mobile's wireless network, and the same is true for passing calls from T-Mobile's network onto Wi-Fi networks. In addition, with the purchase of a HotSpot @Home add-on plan, customers can enjoy the freedom of unlimited, nationwide calling over Wi-Fi.(b)

Available exclusively from T-Mobile, the Katalyst features a sleek, slider design with a sophisticated metallic silver finish and is equipped with Wi-Fi connectivity, Bluetooth® wireless technology and a 1.3 megapixel camera.
