T-Mobile has been working hard to update and improve their networks with faster 4G HSPA+ speeds. They’ve been calling it a network refarm or modernization project, and today have announced their largest update yet. Last week we mentioned 3 or 4 cities were getting updated, but today T-Mobile’s confirmed an additional 14. More details on where can be found below.

T-Mobile earlier this year announced they’d be making improvements to their network to the tune of around $4 billion. They’ve been improving network reach, reliability, and of course speed throughout 2012 and things are looking pretty good. Today they’re rolling out an enhanced and refarmed 1900 MHz HSPA+ spectrum in 14 locations, and some are pretty big. Here’s the list:

New York, including The Bronx, Brooklyn, Manhattan, Queens and Staten Island
Newark, N.J., including the surrounding cities of East Orange, Elizabeth, Jersey City, North Bergen, Paterson and Union City
Boston and Cambridge, Mass., including the surrounding cities of Amherst, Andover, Arlington, Bedford, Belmont, Billerica, Braintree, Brockton, Brookline, Burlington, Canton, Chelmsford, Chelsea, Chicopee, Dedham, Everett, Framingham, Hadley, Holbrook, Holyoke, Lawrence, Lexington, Lowell, Ludlow, Lynn, Malden, Marblehead, Medford, Melrose, Metheun, Milton, Nahant, Natick, Needham, Newton, Quincy, Reading, Revere, Salem, Saugus, Sommerville, Stoneham, Swampscott, Tewksbury, Wakefield, Walpole, Waltham, Watertown, Weston, Westwood, Weymouth, Wilmington, Winchester, Winthrop and Woburn
Springfield, Mass.
Providence, R.I., including the surrounding cities of Cranston, North Providence, Pawtucket and Warren

Tampa, Fla., including the surrounding cities of Clearwater, Largo, Safety Harbor, St. Petersburg and Vinoy Park

Pretty long list you have there T-Mobile. Adding faster network speeds to places like Dallas, Phili, Boston, and much more is pretty impressive. Those aren’t small improvements either. T-Mobile’s modernization process allows for unlocked devices like the Nexus 4, or iPhone to access even faster speeds than before. Making them a pretty awesome choice these days.

It sounds like San Diego and Los Angeles are up next for T-Mobile, and currently their number sits at around 37 markets that have been improved. Reaching well over 100 million customers and growing. Next year we can expect T-Mobile to continue this refarm process, while also rolling out their 4G LTE network.
