ETISALAT, NIGERIA’S FIFTH MOBILE phone company, has unveiled its new network. Hakeem Bello-Osagie, chairman of Emerging Markets Telecommunications Services, or EMTS, owners of the license operated by Etisalat, said that the company is expected to use a marketing strategy of reduced tariffs to take market share from established operators in Nigeria. EMTS, a Nigerian firm, entered into partnership with Mubadala Development Co. of the United Arab Emirates following Mubadala’ s acquisition of a Unified Access License that includes a mobile phone license from the Nigerian government in January 2007 for $400 million. Etisalat has acquired a 40% stake in EMTS and operates the license in Nigeria. Saoud Al Shamsi, Etisalat’s chief executive officer, said the company has built a network that spans the Middle East, Africa and Asia. Nigeria has more than 40 million mobile phone subscribers. Operators include MTN, Globacom, Celtel and Visafone.
