The telecommunications sector in Bahrain officially started in 1981 with the establishment of Bahrain's first telecommunications company, Batelco and until 2004, it monopolised the sector. In 1981, there were more than 45,000 telephones in use in the country. By 1999, Batelco had more than 100,000 mobile contracts. In 2002, under pressure from international bodies, Bahrain implemented its telecommunications law which included the establishment of an independent ''Telecommunications Regulatory Authority'' (TRA). In 2004, Zain (a rebranded version of MTC Vodafone) started operations in Bahrain and in 2010 VIVA (owned by STC Group) became the third company to provide mobile services.
