MTN Group Ltd. , the South African carrier that has tried (but failed) during the past few years to expand its horizons via mergers with Indian carriers, is believed to be closing in on a deal to buy most of the African mobile assets of Orascom Telecom , according to a report from IT News Africa. (See Bharti, MTN Abandon $23B Merger.)

And it seems a deal might be unveiled Tuesday, as trading in Orascom's shares on the Egyptian stock exchange have been suspended because the company is set to announce a "material event" on April 27.

The deal is thought to involve Orascom's subsidiary, Telecel Globe, which operates in Burundi, the Central African Republic, Namibia, and Zimbabwe, plus Orascom's mobile assets in Algeria and Tunisia. Together, these operations have about 20 million customers -- with Algeria (under the brand "Djezzy") by far the largest, with 14.6 million customers at the end of 2009, followed by Tunisia ("Tunisiana") with more than 5 million and annual revenues of more than $2.3 billion.

The deal is not set to include Orascom's minority stake in Egypt's Mobinil , which has been the subject of recent disputes with majority shareholder Orange (NYSE: FTE).

MTN, which has operations in 16 African countries and a number of Middle East markets, generated revenues of more than $15 billion in 2009, and ended last year with 116 million customers. See this press release for more details.
