Bharat Sanchar Nigam expects over Rs 17,000 crore revenue from services in FY22, a tad lower than the previous fiscal, mainly due to the removal of call connect charges that used to bring in additional inflows, according to its Chairman and Managing Director PK Purwar. Purwar asserted that the state-owned telecom corporation is confident of retaining its customer base and defending its turf with quality 4G services to be launched in the coming months, even as competition intensifies with private telcos<\/a> gearing up for 5G<\/a> services.
