T-Mobile touted earlier this year that its 700MHz Extended Range LTE service reaches 190 million people in more than 300 markets. Magenta continues to work on rolling the service out to more cities across the US, though, and recently it’s been spotted in a few more locales:
Florham Park, N.J.
Anacoco, La.
San Jose, Calif.
SJC (San Jose airport), Calif.
Thanks, Spencer, Eric, and Christian!
