BSNL Mobile

On 27 February 2010, BSNL Mobile launched 3G services on Pan India.[6] BSNL Mobile also has 3G Roaming services in Mumbai & Delhi for other circles subscribers through an agreement with MTNL, This gives BSNL Mobile a 3G presence in all 22 out of 22 circles in India.

BSNL Mobile has started providing 4G services in some telecom circles of India.[7] It has deployed LTE Band 1 in those telecom circles, by upgrading its existing 3G towers. As a part of a revamp package promised by the Indian Government, BSNL floated a tender in April 2020 for procuring tower related telecom equipment for LTE deployment in other bands. The ailing network provider hit another roadblock in deploying 4G towers.[8] The Telecom Equipment Promotion Council (India) alleged that BSNL has floated the tender with stringent norms which would discourage the local vendors in the country. Meanwhile, there were no similar guidelines or directions given by any government agencies to any private players, arising a foul play suspicion. As of now, BSNL is expected to roll out 4G services using 60% of its existing towers which are capable of supporting LTE. Currently top management of BSNL are in talks with private network operators like Airtel India,Vodafone Idea for 4G ICRA to commence LTE services once the 4G procurement tender is passed successfully. After that its own 4G network will be available.[9]

BSNL has launched VoLTE services in circles where it is providing its 4G services.[10]
