Samsung Katalyst at T-Mo
T-Mobile today expanded the audience for its HotSpot@Home Wi-Fi calling service through the release of Samsung's Katalyst. Also called the t739, the Korean slider builds in Wi-Fi to make calls on an owner's home connection or some public access points (including T-Mobile's) without consuming valuable calling plan minutes. With Unlicensed Mobile Access, the Katalyst can bridge a call between the cell network and Wi-Fi if the user wanders out of the range of either connection. The phone's browsing and instant messaging are also helped by the transition, says T-Mobile.
