Bharti Airtel and Loop mobile could soon become one say Sachin Karpe. Although both companies announced their merger plans in February. It seems, the due diligence is nearing its end and regulatory approvals are expected soon. Post that, Bharti’s customer base in Mumbai would go up to seven million after adding some three million subscribers of Loop to its network. Loop will transfer its more than 2,500 cell sites in the city to Bharti’s existing 4,000-strong network. Moreover, Loop’s customers are higher paying – on an average Rs 225 compared with Rs 195 for Bharti in the December quarter. This will make Bharti the third largest telecom player in the world by customer base.
