Personal Communications Service or PCS is the name for the 1900-MHz radio band used for digital mobile phone services in Canada and the United States. Code Division Multiple Access (CDMA), GSM, and D-AMPS systems can be used on PCS frequencies. The FCC, as well as Industry Canada, set aside the frequency band of 1850-1990 MHz for mobile phone use in 1994, as the original cellular phone band at 824-849 MHz was becoming overcrowded. Dual-band GSM phones are capable of working in both the 850- and 1900-MHz bands, although they are incompatible with 900- and 1800-MHz European and Asian systems. However, GSM "world phones" (some of which are known as "tri-band" or "quad-band" phones, because they operate in three or four different frequency bands, respectively) offered by American carriers support both European and domestic frequencies. Outside the USA, PCS is used to refer to GSM-1900.
Sprint was the first company to setup a PCS network, which was a GSM-1900 network in the Baltimore-Washington metropolitan area in the USA. Eventually however, Sprint converted that network to CDMA technology and sold the GSM infrastructure to Omnipoint, which later became part of T-Mobile USA. Nowadays, the PCS frequencies have been adopted for usage in most parts of the Americas.
