T-Mobile has officially launched its 4G LTE network in seven major metropolitan areas, including Las Vegas, Nevada; San Jose, California; Houston, Texas; Phoenix, Arizona; Kansas City, Missouri; Baltimore, Maryland; and Washington D.C. This rollout is only the beginning for the fourth largest wireless carrier in the United States, as the goal is to cover 100 million Americans by mid-year and 200 million by the end of 2013. This will compliment T-Mobile’s “4G” HSPA+ network, which covers 225 million people in 229 markets. Subscribers looking to take advantage of the new LTE data speeds with an Android smartphone should look into devices like the Samsung Galaxy Note II, as well as the upcoming Samsung Galaxy S4 and HTC One. The iPhone 5, which supports LTE, will be available from T-Mobile starting April 12. T-Mobile also released its first LTE mobile hotspot, the Sonic 2.0 Mobile HotSpot LTE.
