Bharti Airtel acquired Zain's African operations in 2010 for $10.7 billion to expand into the growing African telecom market. However, operating in multiple African countries posed challenges such as dealing with different regulations, infrastructure issues, strong competition from established players like MTN, and cultural differences between Indian and African business practices. The acquisition also carried significant financial risks due to Zain's losses and the large debt taken on for the deal. While customer growth was lower than expected, Airtel began to see some improvements in metrics after lowering prices and expanding networks and services.
