NTT Docomo, Inc. (TYO: 9437, NYSE:_DCM, LSE:_NDCM) is the predominant mobile phone operator in Japan. The name is officially an abbreviation of the phrase, "do communications over the mobile network", and is also from a compound word dokomo, meaning "everywhere" in Japanese. Docomo provides phone, video phone (FOMA and Some PHS), i-mode (internet), and mail (i-mode mail, Short Mail, and SMS) services. The company has its headquarters in the Sanno Park Tower, Nagatach_, Chiyoda, Tokyo. Docomo was spun off from Nippon Telegraph and Telephone (NTT) in August 1991 to take over the mobile cellular operations. It provides 2G (mova) PDC cellular services on the 800_MHz band, and 3G FOMA W-CDMA services on the 2_GHz (UMTS2100) and 800_MHz(UMTS800(Band VI)) and 1700_MHz(UMTS1700(Band IX)) bands, and 4G LTE services.
