Vi and BSNL Agree to Share Networks Across India: What the Pact Means for Users and the Telecom Race
Vodafone Idea (Vi) and state-owned Bharat Sanchar Nigam Limited (BSNL) have agreed to expand network sharing across Indian telecom circles, according to multiple reports citing industry sources. The understanding follows a meeting in late August 2026 between Vi chief executive Abhijit Kishore and BSNL chairman and managing director Robert J. Ravi. Neither company has issued a formal public statement, and some accounts describe the plan as covering all circles while others say it will first extend the existing arrangement to select service areas. Even so, the direction is clear: two operators that have struggled to keep pace with Reliance Jio and Bharti Airtel want to use each other’s networks and infrastructure instead of building everything twice.
The story is not a sudden alliance. Vi and BSNL already run intra-circle roaming in Delhi and Mumbai, under which BSNL subscribers can use Vi’s network on a revenue-sharing basis. Separately, BSNL had leased about 1,441 towers to Vi as of April 2026, according to Department of Telecommunications data. What sources now describe is a broader commercial framework that would add inter-circle roaming, more tower tenancy, and optical fibre sharing. If implemented at scale, a Vi customer in a weak-coverage pocket could fall back on BSNL, and a BSNL customer could ride Vi’s denser urban grid. That is the practical meaning of intra-circle and inter-circle roaming: the phone stays on the same SIM, but the radio network underneath can change.
Why the two operators need each other
India’s wireless market is effectively a two-horse race at the top. Jio and Airtel control the bulk of subscribers, spectrum depth, tower sites and fibre kilometres. Industry estimates cited in coverage of the talks put Vi on roughly 190,000 towers and BSNL on about 121,000, against around 333,000 for Jio and 292,000 for Airtel. The fibre gap is even starker. Vi has deployed around 165,000 km of fibre, while Jio’s network runs well over a million kilometres and Airtel’s is in the region of 550,000 km. Those numbers explain dropped calls, uneven 4G, and slower 5G rollout outside premium cities. They also explain why capital expenditure has become a survival issue rather than a growth luxury.
Vi has been trying to rebuild after years of subscriber losses, high debt and delayed network spend. In the June quarter of FY27, the company reported operating revenue of ₹11,689 crore, up 6 percent year on year, and EBITDA of ₹5,034 crore. The net loss narrowed to ₹3,754 crore from ₹6,608 crore a year earlier. Management also pointed to the first quarter of net subscriber additions since the Vodafone–Idea merger, with the base around 193 million. Chairman Kumar Mangalam Birla has described the current year as one of execution, with capex orders already placed and funding efforts under way. Sharing BSNL’s sites and fibre would not replace that investment. It would stretch it.
BSNL’s problem is different but complementary. The public sector operator still has reach in many rural and semi-urban pockets and a large tower and fibre estate built over decades. Its weakness has often been quality and capacity in dense cities, plus a slower 5G start. Letting customers roam onto Vi in those urban gaps, and earning tenancy income when Vi sits on BSNL towers, is a cheaper way to look bigger than a full standalone build. The government owns BSNL outright and holds a large stake in Vi after earlier rescue steps, close to 49 percent. That ownership overlap is why New Delhi has treated infrastructure sharing as policy, not just a private commercial idea. Earlier in 2026, the Department of Telecommunications told a parliamentary committee that talks on towers, fibre and even spectrum had begun, and the committee asked for a structured plan with timelines and estimated savings.
What sharing actually includes
Reports break the latest understanding into three layers.
First, roaming. Intra-circle roaming already exists in Delhi and Mumbai. Extending it across more circles, and adding inter-circle roaming, would let users keep service when they travel or when one operator’s signal disappears inside the same state. Settlement would almost certainly stay on a revenue-share or usage-charge model, similar to the metro arrangement already in force.
Second, passive infrastructure. Towers, shelters, power and related site assets are expensive to replicate. Raising Vi’s tenancy on BSNL towers for 4G and 5G, and opening more BSNL sites to Vi radios, is the fastest way to add coverage without waiting for land, power connections and civil work.
Third, optical fibre. Backhaul is the hidden constraint behind “full signal, slow internet.” Sharing fibre, including work already explored under BharatNet-linked pilots, can fibreise more base stations and improve consistency. Spectrum sharing has been discussed in earlier official briefings, but it is more sensitive and is not confirmed as part of the late-August understanding. Passive sharing and roaming can move first; airwave pooling would need tighter regulatory and commercial design.
What users and the market should expect
For subscribers, the promise is simple: fewer dead zones if the networks actually interwork. A BSNL user in a Vi-strong city neighbourhood should see better indoor data. A Vi user on a highway or in a small town where BSNL still has a mast should keep a call that would otherwise drop. Quality will still depend on how the operators configure handover, capacity and billing. Roaming onto a partner network is not the same as owning a dense 5G grid.
For Vi, extra traffic from BSNL users is incremental revenue in places where the private network already exists. That matters because every rupee of utilisation improves the case for keeping sites live. For BSNL, urban quality and tenancy income matter as much as rural pride. Both sides also want lower duplication. Building parallel towers a few hundred metres apart wastes capital that could go into 5G radios, fibre or debt service.
Investors treated the reports as one more turnaround signal rather than a finished contract. Vi shares had already been climbing on funding hopes, AGR relief and better quarterly trends, touching a 52-week high near ₹15.37 in late August before easing. A sharing pact does not by itself close the gap with Jio and Airtel. It can, however, reduce the cash needed to look competitive in more circles while Vi executes its own capex programme.
What is still missing
The important caveats are official confirmation, circle-by-circle lists, commercial rates, technology scope (2G, 4G, 5G) and go-live dates. Roaming and infrastructure sharing need technical integration, traffic settlement rules and regulatory comfort. Some coverage has used “all circles”; more cautious reports say “select circles” first. That difference is not small. A nationwide reciprocal network is a third-force strategy. A handful of additional circles is an incremental cost-saving step.
There is also a structural question that will linger. Because the state stands behind BSNL and holds a large Vi stake, deeper sharing can look like the first stage of a public-sector telecom layer rather than a normal private partnership. That does not require a merger. Tower tenancy, fibre indefeasible rights of use, and coordinated 4G/5G rollout can deliver most of the operating benefit with less political friction. Whether spectrum is ever pooled will be the real test of how far the two sides are willing to go.
Until Vi or BSNL publish terms, the late-August reports should be read as an agreed direction, not a finished product. The logic is straightforward. India already has two national-scale private networks. The third and fourth operators cannot spend like the first two. Sharing towers, fibre and coverage is how they try to stay in the race—and how their customers might finally get a more usable signal without waiting for another full round of construction.
