As T-Mobile continues to modernize their network, known as a refarm, they’ve announced today that today three new Metro areas will all be getting better and faster HSPA+ speeds. T-Mobile took this moment to also state unlocked devices like the iPhone will get 70% faster speeds than on AT&T’s network, but this also holds true for all Android devices.

T-Mobile’s been modernizing their network and allowing more unlocked devices to have full HSPA+ 4G support instead of the old usual 3G speeds when a device isn’t sold directly from T-Mobile. So this holds true for those who bought international Galaxy S III, Note II’s, and anything else as of late.

T-Mobile has confirmed that Washington, D.C., Houston, and the greater Baltimore area have all received a massive overhaul and improvement to their HSPA+ speeds and network. Some of those are:

Washington D.C.: Alexandria, VA; Arlington, VA; Chevy Chase, MD; Falls Church, VA; Laurel, MD; McLean, VA; and Silver Spring, MD.
Baltimore: Glen Burnie and Towson, MD
Houston: Cypress, Jersey Village, Humble, Kingwood, and The Woodlands.

That brings their refarming process to a total of 5 markets. The other two being Kansas City and Viva Las Vegas. T-Mobile says it will be equipping several more metro areas before the end of the year, as it transitions old 2G service on the 1900MHz band over to HSPA+ use for all.

This is an extremely long process for T-Mobile, and we don’t expect to see a large increase any time soon, as they’re also preparing for their 4G LTE network rollout in 2013. However, for those wanting to get cheaper T-Mobile plans for their international devices, the LG Nexus 4, iPhone and more this will be a good place to start. Sadly speeds won’t be the same outside of these refarmed locations. Stay tuned for more details as T-Mobile will start announcing more 4G LTE plans soon.
