Why Vodafone Idea Shares Are in Focus After BSNL Network Sharing Pact

Vodafone Idea and Bharat Sanchar Nigam Ltd. (BSNL) have reached an agreement to expand their existing network-sharing relationship across all telecom circles, according to media reports. The development follows a meeting between Vodafone Idea CEO Abhijit Kishore and BSNL Chairman and Managing Director Robert J. Ravi on Tuesday.

Under the proposed arrangement, subscribers of both operators could gain access to each other’s networks across different service areas, while the companies are also expected to share telecom towers and optical fibre.

What does BSNL-Vodafone Idea agreement cover?

The proposed network-sharing pact is expected to include both intra-circle and inter-circle roaming arrangements. This would allow subscribers of one operator to access the other operator’s network in different service areas.

The broader infrastructure-sharing arrangement includes:

• Intra-circle roaming

• Inter-circle roaming

• Telecom tower sharing

• Optical fibre sharing

• Greater infrastructure utilisation for 4G and 5G services

BSNL and Vodafone Idea already have an intra-circle roaming arrangement in Delhi and Mumbai, under which BSNL subscribers can use Vodafone Idea’s network on a revenue-sharing basis.

The latest agreement is expected to extend this model across all telecom circles.

How could Vodafone Idea benefit?

For Vodafone Idea, the arrangement could provide additional revenue from BSNL subscribers using its network, particularly in areas where BSNL has limited coverage.

Higher network traffic could also improve utilisation of Vodafone Idea’s existing infrastructure. Access to BSNL’s towers, optical fibre, rights of way and real estate footprint could help the company reduce deployment costs and delays as it expands its 4G and 5G networks.

BSNL had leased around 1,441 towers to Vodafone Idea as of April 2026, according to the Department of Telecommunications. The two operators had also been discussing deeper infrastructure sharing, including increasing Vodafone Idea’s tenancy on BSNL’s towers.

How could BSNL benefit?

BSNL could use Vodafone Idea’s network to strengthen coverage in rural and other areas where its own network presence is limited.

Instead of building or upgrading infrastructure at every location, BSNL could use Vodafone Idea’s network through roaming arrangements. This could allow the state-run operator to expand its reach while making greater use of infrastructure sharing.

The arrangement also fits with BSNL’s broader objective of controlling costs and monetising infrastructure, while benefiting from Vodafone Idea’s experience in customer acquisition and go-to-market execution.

Could the pact improve competition against Jio and Airtel?

The deeper partnership could help both operators pool complementary infrastructure and reduce duplication as they compete with Reliance Jio and Bharti Airtel.

According to the source, Vodafone Idea has a presence on about 190,000 towers and BSNL on 121,000 towers, compared with around 333,000 sites for Jio and 292,000 for Airtel. In fibre infrastructure, Vodafone Idea has deployed around 165,000 km of fibre, while Jio has more than 1 million km and Airtel about 550,000 km.

The government owns BSNL and holds a 49% stake in Vodafone Idea, giving it an interest in reducing infrastructure duplication and extracting greater value from both investments.

Conclusion: What does this mean for your portfolio?

BSNL-Vodafone Idea network-sharing agreement could improve network reach, increase infrastructure utilisation and reduce duplication for both operators. For Vodafone Idea, potential revenue from BSNL subscribers and access to BSNL infrastructure could support its network expansion, while BSNL could use Vodafone Idea’s network to strengthen coverage.
