India's Bharti Airtel has entered into a definitive agreement with the UAE-based Warid Group to acquire its telecom operations in Congo.

The acquisition will make Airtel the largest mobile operator in Congo with around 2.6 million customers, the company was quoted as saying by an Economic Times report.

It, however, did not reveal the financial details of the deal.

Bharati Airtel, about 32 percent owned by Singapore Telecommunications, said the agreement aims to bring together the strengths of Airtel and Warid in Congo Brazzaville and benefit customers in the form of affordable tariffs, superior 2G/ 3G network and affordable voice and data services.

Existing Warid customers in Congo Brazzaville will now be part of 'One Airtel' network with affordable roaming rates across Africa and South Asia, it added.

With operations in 20 countries, Bharti Airtel is ranked fourth largest mobile operator globally.
