Vodafone's only other standalone business in sub-Saharan Africa is in Ghana, and there have yet to be discussions between the two companies about that unit, Mr Joosub said.
Vodacom, which is majority-owned by Vodafone Group Ltd., plans to acquire 87.5% of the issued share capital of Vodafone Kenya Ltd., which holds a 40% interest in Safaricom and is wholly owned by Vodafone.
"While Safaricom share-- in some segments remain high, we firmly believe this has been attained through prudence investment and continuous innovation, both of which are integral to our strategy", Collymore said on May 10.
"I think by consolidating the African businesses, you could apply scale and target these markets to make a wider opening to Vodacom and Safaricom".
Commenting on the proposed transaction, Shameel Joosub, Chief Executive Officer of Vodacom Group, said: "This is an exciting occasion for Vodacom and a unique opportunity to diversify our revenue growth and profitability".
He added that the deal "promotes the continued successful expansion of the company as well as the opportunity to drive M-Pesa to other markets on the continent".

As part of the transaction, Vodafone Group has given appropriate assurances to the government of Kenya to ensure the ongoing success of the long standing partnership between Safaricom, Vodafone Group and the government.
Safaricom is the market leader in Kenya with 71 per cent of the country's subscribers, and is under pressure from lawmakers and regulators who are debating ways to break its dominant position in the market.
It will also help increase the use of Safaricom's popular M-Pesa money transfer service across Africa. Vodafone stock declined 0.8 per cent in London.

Still, Vodacom said its global operations added 2.5 million customers for the year, with worldwide data revenue up 2.3% to 4.11 billion rand, thanks to a 29% increase in customers that use data to 13 million.
The group declared a final dividend of R4.35, taking its total for the year to R8.30, a 4.4% raise on the previous year's R7.95.
