Reliance Communications (RCom) has crossed the 10-crore subscriber mark while it planned to add similar number of mobile subscribers in the next three years. Apart from RCom, Bharti Airtel is the only other operator to have crossed the 10-crore subscriber mark. “The landmark 10-crore mobile customer base makes us the youngest telecom operator to achieve this milestone in such a short span of time. As we take the leap to achieve the 20-crore mark, we will lead it from the front with more customer-centric innovations and service approach,” Reliance ADA Group Chairman Anil Ambani said in a statement.
