Bharat Sanchar Nigam Limited (BSNL) is India's largest public sector telecommunications company. It was established in 2000 and took over telecom operations from the Department of Telecom. BSNL provides both fixed telephony via landlines as well as cellular services across India using technologies like GSM, CDMA, FTTH, and WiMax. It aims to be the leading telecom provider in India through excellent customer service and affordable innovative products. However, it faces threats from private operators and needs to improve its marketing strategy, franchise network, and customer satisfaction.
