Through a series of acquisitions and mergers, within 10 years, the company consisted of a two-way parnership between BellSouth and AT&T Wireless. This partnership was also known as BellSouth Mobility, LLC. Houston Cellular began providing service in May 1986.
Houston Cellular was formed as a result of the October 1983 Federal Communications Commission's ruling that set aside sufficient frequencies for the operation of two cellular systems in each metropolitan area. In the early 1990s, this ruling was expanded with the advent of the 800 and 1900 MHz protocols, which are also known as PCS). The ruling reserved one system for application by local phone companies. In Houston, the competing non-local company service was applied by GTE Mobilnet.
In 2006, the parent company of Southwestern Bell Mobile Systems, AT&T Inc., acquired BellSouth. Eventually, this led to the renaming of Cingular Wireless, LLC to AT&T Mobility, LLC. The service is now branded as "Wireless from AT&T, formerly Cingular Wireless", "Wireless from AT&T" or sometimes simply "AT&T".
