T-Mobile has been the official wireless carrier of MLB since 2013, and has recently updated its network at ballparks in Miami, New York, Seattle, Washington D.C. and others. For the All-Star game, the mobile operator has added VoLTE capabilities throughout the entire city, along with Wideband LTE. The carrier has also upgraded its network on Target Field's Distributed Antenna System. This should enhance the wireless experience for fans attending the contest at the ballpark.
Besides getting the opportunity to meet All-Stars, those attending T-Mobile FanFest can participate in hitting and pitching clinics and sign up to participate in T-Mobile Test Drive. This program allows consumers to test out the T-Mobile network free for one week, on an Apple iPhone 5s, with no risk or obligation. Sounds like a Home Run.
