T-Mobile 4G LTE: Where to Expect it Next Adam Mills05/03/2013 T-Mobile looks like it will be making big strides in its attempt to catch the 4G LTE networks of its rivals as a new leak suggests that the carrier is prepping a massive expansion of its new high-speed network, set to take place in both May and June. Earlier this year, T-Mobile finally rolled out its own 4G LTE network, far later than its rivals AT&T, Sprint and Verizon, all of which have been working for a number of months, and in the case of Verizon, years, to expand their high-speed networks across the United States. And while T-Mobile has entered the picture late, it hopes to play catch up in 2013 with plans to cover over 200 million Americans with its new network.Advertisement Read: T-Mobile 4G LTE Speed Test: Galaxy Note 2 Picks Up Serious Speed. The T-Mobile 4G LTE network might get larger in May and June. Thus far, its LTE footprint is rather small, checking in with only a few LTE cities including Baltimore, MD, Kansas City, KS, Houston, TX, Las Vegas, NV, Phoenix, AZ, San Jose, CA and Washington D.C. And while the network is small right now, it looks like it will be growing very soon.Advertisement TMoNews has unearthed a massive list of probable T-Mobile 4G LTE markets that are apparently set to go live in both May and June. As it notes, these are subject to change, but these are likely going to be the places where T-Mobile’s 4G LTE network strikes next, whether it’s in May, June or beyond.Advertisement Fortunately for T-Mobile customers who may have just bought the HTC One or Samsung Galaxy S4, both of which have LTE enabled, the list is pretty expansive and includes not only major metropolitan areas but smaller cities as well. In the month of May, Austin, Texas; Honolulu, Hawaii; Minneapolis and St Paul, Minnesota; Tulsa, Oklahoma; Sacramento, California; Philadelphia, Pennsylvania are all thought to be getting 4G LTE data speeds. Parts of Los Angeles and San Francisco will apparently go live as well, but those roll outs evidently will last into June. T-Mobile’s 4G LTE network is much faster than its 3G network. In June, T-Mobile is rumored to be firing up 4G LTE data speeds for the Atlanta area, Charlotte and Rock Hill in the Carolinas, Chicago, Cleveland, Bridgeport, Stamford, Norwalk in Connecticut, Columbus, Dallas which includes Fort Worth, Detroit, Long Island and areas in New York and New Jersey, Oklahoma City, Orlando, Miami, Boston and Cambridge, San Diego, Oakland, and Tampa.Advertisement Needless to say, if this pans out, it’s an ambitious roll out for T-Mobile and fantastic news for its customers. The carrier remains mum on these cities so it will take an announcement to make it official but don’t be surprised if these are the next markets that get the Magenta carriers new high-speed network in the coming weeks.
