Earlier today, T-Mobile officially confirmed that its Extended Range LTE (aka band 12) coverage is now live in Philadelphia and a bunch of other Pennsylvania cities. And while T-Mo has announced quite a few official Extended Range LTE launches in recent months, we know that Magenta is testing and prepping that coverage in other cities across the US without making any official announcements.

Here are some of the recent places that Extended Range LTE coverage has been spotted:

Lexington Park, Md.

Bakersfield, Calif.

Pine Cove, Calif.

Leesburg, Fla.

Bronx, NYC

Monroe Township, NJ

Palm Desert, Calif.

Rancho Santa Margarita, Calif.

T-Mobile has a goal of covering more than 350 markets with Extended Range LTE by the time that 2015 is up, and while we’re getting close to the end of the year, I wouldn’t be surprised to see a few more announcements before 2015 comes to an end. While we wait, keep an eye out for some of that Extended Range LTE goodness in your neck of the woods.

Thanks, Marlon Jay, Crosby, Daniel, Stephen, Arturo, Anonymous, Aaron, and Alexander!
