Pocket Communications was a PCS CDMA 1xRTT provider of unlimited cellular phone service based in San Antonio, Texas, United States. It offered service plans similar to those of Cricket Communications and MetroPCS with unlimited local phone and messaging service on a month to month basis with no contract. Its founder Paul Posner started as a local paging operator in San Antonio before becoming a dealer for Southwestern Bell Mobile Systems, Houston Cellular, and BellSouth Mobility in 7 markets in Texas and the Southeast under the name Discount Cellular & Paging. After selling these operations in 1997, Posner spent 7 years trying to acquire FCC licenses required to build a cellular network and was ultimately successful in FCC Auction 58 in 2004. Pocket launched service in 2006 in San Antonio and competed directly with Cricket Communications in the only US market where two flat-rate providers competed head to head. Pocket's unique marketing strategy included operating hundreds of small retail locations with just one employee, oversaturation of billboard advertising, and the use of chimpanzees in its advertising. In its first year of operations, Pocket became the fastest growth company in the history of the US wireless communications, achieving positive cash flow in just 6 months. Subsequent expansion from San Antonio to Laredo, the Rio Grande Valley, and Corpus Christi markets and a customer base of over 400,000 subscribers ultimately led to a merger offer from Cricket Communications in late 2010. Cricket was subsequently sold to ATT in 2015. ATT continues to operate Cricket as a stand-alone business and a "flanker brand.
