Sudanese Mobile Telephone Company, Zain (formerly Mobitel) is the pioneer of GSM services in Sudan, being the first to offer mobile operations back in February 1997. Today it serves the largest base of mobile customers in the country with more than 10 million active customers. Zain (then known as Mobitel) was a joint venture between the Sudanese Telephone Company Ltd and several private shareholders until 2006, when it was fully acquired by the Zain Group (formerly MTC) as part of its strategy of becoming first a regional, then a global telecom entity. With this acquisition MTC consolidated its position in both the Middle East and Africa enabling Mobitel, the pioneering and leading mobile telephone operator in Sudan.
