Earlier today we learned that T-Mobile now has 4G LTE service available for more than 180 million people across 154 markets. And while that is a nice step up for T-Mobile (as compared to their previous status update), it also looks like AT&T has continued making progress towards their end-of-year goals. In fact, AT&T now has 4G LTE available in 400 markets.

To that point, those 400 markets translate into having 4G LTE available for “nearly” 240 million people. Further details point towards AT&T having 4G LTE services available for 270 million people by the end of 2013. Looking forward into next year and we see comments from AT&T about how they expect the 4G LTE build to be “substantially complete by summer 2014.”

Otherwise, AT&T also took this 400 market announcement as time to say that more than 35 percent of the postpaid subscribers are now using a 4G LTE capable device. Perhaps more important for the present time though, this 400 market announcement also came with word of new coverage.

AT&T has rolled out coverage for those in Alexander City, Alabama; Concord, New Hampshire and Jamestown, New York. In addition, coverage has also been expanded for those in Fresno, San Francisco and Stockton, California; Washington DC; Springfield, Missouri; Columbus, Ohio; Nashville, Tennessee; Houston, Texas, Seattle and Tacoma, Washington and Charleston, West Virginia.

In addition to new LTE coverage, AT&T has also been steadily rolling out new devices. The LG G2 recently arrived and we also learned the Metallic Blue HTC One will be available (for AT&T) by way of Best Buy on September 15. Aside from smartphones, AT&T recently released the ASUS MeMO Pad FHD LTE 10.0 tablet earlier in the month.
