Unlike its competitors, T-Mobile is yet to roll out across the country its LTE network, which it only plans to introduce next year. What T-Mobile does have is a solid HSPA+ network infrastrucutre, one that T-Mo says is just as good as 4G LTE.

If you’ve been looking to use your unlocked 4G handsets on T-Mobile, here’s a list of the new metro areas that are now covered by the carrier’s enhanced 4G HSPA+ network.

• Chicago, including the surrounding areas of: Aurora, Berwyn, Chicago Heights, Cicero, Des Plaines, Downers Grove, Evanston, Evergreen Park, Naperville, Oak Park, Schaumburg, Wilmette, and Winnetka.
• Reno, Nevada
• Sacramento, California, including the surrounding areas of: Antelope, Citrus Heights, Elk Grove, Fair Oaks, Folsom, Loomis, North Highlands, Rancho Cordova, Rio Linda, Rocklin, Roseville, Vacaville, and West Sacramento.
• Fresno, California
• Southern California, including: Alhambra, Anaheim, Claremont, Culver City, El Monte, Encino, Garden Grove, Granada Hills, Inglewood, Irvine, La Crescenta, Laguna Niguel, Monrovia, Monterey Park, Newport Beach, North Hills, North Hollywood, Paramount, Pasadena, Redlands, Reseda, Rosemead, Santa Ana, San Fernando, San Gabriel, Santa Monica, South El Monte, Temple City, Torrance, Upland, Valley Village, Van Nuys, Westminster, and Wilmington.

Although T-Mobile specifically mentions the iPhone as the device that can benefit from the HSPA+ speed, we can think of many awesome 4G Android smartphones, which aren’t available on the carrier, that can take advantage of the enhanced network — such as AT&T’s HTC One X+ and Verizon’s HTC Droid DNA.
