Vodafone Idea and BSNL are set to expand their existing network-sharing arrangement beyond Delhi and Mumbai, potentially covering roaming, towers and optical fibre across India.
The Vodafone Idea BSNL network sharing arrangement is set for a significant expansion, with the two telecom operators agreeing in principle to take their existing collaboration beyond Delhi and Mumbai. The proposed arrangement could cover all telecom circles and include roaming as well as sharing of towers and optical fibre infrastructure.
The development follows a meeting between Vodafone Idea leadership and BSNL Chairman and Managing Director Robert J. Ravi. According to BSNL reports citing people familiar with the discussions, the two operators are looking at both intra-circle and inter-circle roaming arrangements as part of a wider network-sharing framework.
Vodafone Idea BSNL Network Sharing Could Go Nationwide
The key change in the Vodafone Idea BSNL network sharing plan is its proposed nationwide scope. The existing arrangement is more limited, with BSNL subscribers already able to access Vodafone Idea’s network in Delhi and Mumbai under an intra-circle roaming arrangement.
The proposed expansion could allow the operators to extend similar arrangements to additional telecom circles. This would potentially give BSNL customers access to Vi infrastructure in areas where BSNL’s own network footprint may be limited, while also creating opportunities for Vi to utilise BSNL infrastructure where that makes commercial and operational sense.
However, it is important to distinguish between the reported agreement in principle and a fully operational nationwide service. The details of commercial agreements, rollout schedules and implementation across individual circles will determine when customers actually see the benefits.
Roaming Will Be a Major Part of the Arrangement
The Vodafone Idea BSNL network sharing proposal is not limited to physical infrastructure. The reported plan includes both intra-circle roaming (ICR) and inter-circle roaming (ICR/roaming across service areas) arrangements.
In simple terms, roaming arrangements allow a subscriber of one operator to access another operator’s network under an agreed framework. For BSNL, this could be particularly useful in locations where its network availability is weaker than that of Vi.
For Vodafone Idea, the arrangement could provide another avenue to monetise network capacity. BSNL users accessing Vi’s network could generate revenue for the private operator under the commercial terms agreed between the companies.
BSNL and Vi Already Have a Network-Sharing Relationship
The Vodafone Idea BSNL network sharing development does not represent the beginning of cooperation between the two operators. They already have an intra-circle roaming arrangement covering Delhi and Mumbai, where BSNL subscribers can use Vodafone Idea’s network.
The Department of Telecommunications had also disclosed earlier this month that BSNL and Vodafone Idea were discussing deeper infrastructure sharing, including the use of BSNL towers for Vi’s 4G and 5G deployments.
This makes the latest development more of an expansion of an existing relationship rather than an entirely new partnership.
Towers and Optical Fibre Could Be Shared
One of the most significant elements of the Vodafone Idea BSNL network sharing proposal is infrastructure sharing. The two companies are expected to make telecom towers and optical fibre available to each other as part of the broader arrangement.
Tower sharing can reduce the requirement for operators to build duplicate passive infrastructure in the same locations. Instead of deploying a completely new tower at every required site, an operator can potentially place its radio equipment on an existing tower, subject to technical, commercial and regulatory conditions.
Optical fibre sharing can similarly help reduce the cost and time involved in connecting network sites. Fibre connectivity is increasingly important for 4G capacity expansion and 5G deployment because mobile sites need high-capacity backhaul to carry traffic into the core network.
BSNL Already Shares Thousands of Towers
The Vodafone Idea BSNL network sharing plan comes against the backdrop of BSNL increasingly using infrastructure sharing as a way to optimise its assets and generate additional revenue.
According to information reported from the Department of Telecommunications, BSNL had leased approximately 1,441 towers to Vodafone Idea as of April 2026. The government has also indicated that discussions were underway to increase Vi’s tenancy on BSNL’s infrastructure for 4G and 5G services.
BSNL’s infrastructure-sharing activity is considerably broader than its relationship with Vi. The DoT said BSNL had leased 11,398 towers to other telecom service providers during FY2025-26, generating around Rs 1,019 crore, while it had leased 26,457 towers from other operators and infrastructure providers.
This highlights why infrastructure sharing could become increasingly important for India’s telecom sector.
Why Vodafone Idea Could Benefit
For Vodafone Idea, the Vodafone Idea BSNL network sharing expansion could provide a relatively cost-efficient way to improve network reach.
The company has been working on expanding its 4G and 5G footprint while operating under considerable financial constraints. Access to existing BSNL infrastructure could potentially reduce the need for Vi to deploy new passive infrastructure in every location.
The benefit is particularly relevant for locations where network expansion would otherwise require significant tower, fibre and site-acquisition expenditure.
There is also a potential revenue opportunity. If BSNL subscribers are allowed to use Vi’s network across more circles, Vi could earn additional network-access revenue without acquiring those users as direct subscribers.
BSNL Could Improve Coverage Faster
For BSNL, the Vodafone Idea BSNL network sharing arrangement could complement its ongoing 4G expansion.
BSNL has been deploying a large indigenous 4G network under the government’s network expansion programme. However, building a nationwide mobile network is a complex process involving spectrum, sites, radio equipment, transmission, fibre backhaul and power infrastructure.
Network sharing can help bridge coverage gaps while the operator continues its own rollout.
The government said in July that around 24,000 mobile towers had been commissioned across India under various government-funded mobile projects and the 4G Saturation scheme by June 2026. It also said 5G services had reached 99.9% of districts.
The proposed Vi-BSNL cooperation could therefore complement rather than replace BSNL’s own network investments.
What It Could Mean for BSNL Customers
For consumers, the most visible benefit from the Vodafone Idea BSNL network sharing expansion could be better network availability.
A BSNL subscriber travelling outside a strong BSNL coverage area could potentially gain access to Vi’s network if the relevant roaming arrangement becomes operational in that circle. This could be especially useful on highways, in urban pockets and in areas where the two operators have different coverage strengths.
However, customers should not assume that BSNL and Vi networks will automatically become one combined network. Network-sharing arrangements are governed by technical configurations, spectrum availability, roaming agreements and commercial terms.
Actual coverage and network speeds will continue to depend on the infrastructure available at a particular location.
Could Vi Also Benefit From BSNL’s Infrastructure?
The Vodafone Idea BSNL network sharing arrangement could work in both directions.
Vi can potentially use BSNL’s towers and fibre infrastructure in selected locations, while BSNL subscribers could gain access to Vi’s network through roaming. This creates a model in which both operators can extract greater value from infrastructure they already have.
For BSNL, leasing infrastructure provides an additional revenue stream. For Vi, using existing sites can potentially reduce deployment costs and accelerate network expansion.
The DoT has previously highlighted infrastructure sharing as a way for telecom operators to reduce capital expenditure and speed up network deployment.
4G and 5G Are Important to the Partnership
The Vodafone Idea BSNL network sharing arrangement could become particularly important as both operators expand modern mobile networks.
BSNL is accelerating its indigenous 4G rollout and preparing the foundation for its future 5G services. Vi, meanwhile, has been deploying 5G and expanding its 4G capacity.
Sharing passive infrastructure such as towers can support both technologies. However, tower sharing does not mean that one operator automatically gets access to another operator’s spectrum or entire radio network.
Each operator would continue to manage its own spectrum and active network components, subject to the specific technical and commercial model adopted.
Nationwide Sharing Could Change the Competitive Landscape
The Vodafone Idea BSNL network sharing expansion could have wider implications for India’s mobile market.
India currently has three major private/state-backed national mobile operators competing at scale: Reliance Jio, Bharti Airtel and Vodafone Idea, alongside state-run BSNL. Greater cooperation between Vi and BSNL could strengthen the competitive position of the two operators without requiring a merger.
For consumers, stronger networks from both companies could provide an alternative to the country’s two largest private operators.
It could also encourage more efficient use of telecom infrastructure. Instead of every operator independently building infrastructure in every location, sharing can allow existing assets to support multiple networks where technically and commercially feasible.
What Happens Next?
The next stage for the Vodafone Idea BSNL network sharing plan will be the detailed implementation framework.
The operators will need to finalise commercial terms, roaming arrangements, infrastructure access, technical integration and circle-wise deployment. Regulatory and operational requirements will also need to be addressed before customers can expect nationwide benefits.
The current development should therefore be viewed as an important step towards broader cooperation rather than an immediate nationwide network merger.
Vodafone Idea BSNL Network Sharing: What It Means
The proposed Vodafone Idea BSNL network sharing expansion could become one of the more significant infrastructure-sharing developments in India’s telecom sector.
For BSNL, access to Vi’s network could help address coverage gaps while its own 4G network continues to expand. For Vi, access to BSNL’s towers and fibre could help reduce infrastructure costs and potentially accelerate 4G and 5G deployment.
The biggest question now is execution. If the reported nationwide framework moves from an agreement in principle to commercial and technical implementation, BSNL and Vi customers could gradually see wider network access across more parts of India.
With BSNL already investing heavily in its network and Vi looking for cost-efficient ways to strengthen its footprint, deeper infrastructure and roaming cooperation could give both operators a more efficient way to compete in India’s increasingly data-heavy telecom market.
