==Operations==

===3G===
On 27 February 2010, BSNL Mobile launched 3G services on Pan India.<ref name="BSNL 3G pan india launch">{{cite news|first=Nikhil|last=Pahwa |url=https://economictimes.indiatimes.com/news/politics-and-nation/bsnl-launches-3g-pan-india/articleshow/4170295.cms |title=economictimes.indiatimes.com |newspaper=The Economic Times |publisher=ET India|accessdate=22 March 2019}}</ref> 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.

===4G===
BSNL Mobile has started providing 4G services in some telecom circles of India.<ref name="BSNL 4G Launched in Some Circles">{{cite web|first=Nikhil|last=Pahwa |url=https://www.indiatoday.in/technology/news/story/bsnl-expands-its-4g-volte-services-to-more-circles-offers-bonus-data-to-subscribers-upgrading-to-4g-sim-1468859-2019-03-02 |title=www.indiatoday.in |publisher=India Today|access-date=22 March 2019}}</ref> It has deployed [[LTE (telecommunication)|LTE]] [[LTE frequency bands|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.<ref name="BSNL to revise Rs 9,000 crore worth tender for 4G gear purchase"> {{cite web |first=Muntazir|last=Abbas |url=https://telecom.economictimes.indiatimes.com/news/bsnl-4g-tender-to-be-reworked-as-per-policy/75430317 |title=BSNL to revise Rs 9,000 crore worth tender for 4G gear purchase |publisher=The Economic Times|access-date=1 June 2020}}</ref> 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.{{Citation needed|date=January 2021}} Meanwhile, there were no similar guidelines or directions given by any government agencies to any private players, arising a foul play suspicion.{{Citation needed|date=January 2021}} 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.<ref name="BSNL approves 2G, 3G network upgrade contract to ZTE, Nokia for fastest 4G rollout"> {{cite web |first=Muntazir|last=Abbas |url=https://telecom.economictimes.indiatimes.com/news/bsnl-approves-2g-3g-network-upgrade-contract-to-zte-nokia-for-fastest-4g-rollout/75576363 |title=BSNL approves 2G, 3G network upgrade contract to ZTE, Nokia for fastest 4G rollout |publisher=The Economic Times|access-date=1 June 2020}}</ref>
