T-Mobile is just about ready to join the 4G LTE circus with the first devices enabled for the network rumored to launch later this month. This includes the LTE-enabled Galaxy S3, which recently made its way through the FCC, lending credence to a supposed March 27th (or April 3rd) launch date.
The phone features full support for TMo’s LTE Band 4 as well as the HSPA+ 850, 1700, and 1900MHz bands. For one reason or another, this version of the GS3 also features support for AT&T’s LTE Band 17. The phone gets model number SGH-T999L (a slight alteration of T-Mobile’s original GS3′s SGH-T999).
T-Mobile has been testing their LTE network in markets from Las Vegas to Kansas, though word of a wider deployment hasn’t been given. Look for the next-gen network to launch in a small number of markets alongside the release of new devices before gradually spreading to cover larger areas of the nation.
