Bharti Airtel is continuing its African expansion with plans to spend $25 million (€20 million) on a 3G network and mobile money service in Malawi.
India's largest mobile operator also pledged to make a $10 million investment in green energy in the nation by the end of the financial year, the IANS news agency reported.
Malawi has a population of around 13.9 million. Research firm BuddeComm estimates that the market has a mobile penetration of 29%.
Bharti Airtel first entered Africa through the $10.7 billion acquisition of Saudi operator Zain's African assets in 16 countries.
While its African operations have been a drain on group finances and the company has encountered unexpected legal and regulatory setbacks, Bharti Airtel remains committed to the market, and Airtel Africa now operates GSM networks in 20 counties.
