The Telecom Regulatory Authority of India (TRAI) has released its official subscription indicator review for the period ending May 31, 2026. While the absolute, gross wireless metrics show minor customer additions for all top private operators, the underlying quality data points to an ongoing problem for Vodafone Idea (Vi). The carrier continues to struggle with active user retention, losing ground in the industry’s most critical revenue-generating segment.
The data reveals that while Vi is marginally growing its overall, unverified customer footprint, it is bleeding its actual active user base at an accelerating rate. For investors tracking telecom stocks India 2026, this widening gap between paper additions and actual on-network activity presents a significant fundamental challenge as the company attempts to close upcoming debt-refinancing lines.
The Core Metric: Gross Subscribers vs. Peak VLR Reality
In the telecommunications sector, financial health is determined by the Visitor Location Register (VLR) data rather than raw, gross subscriber registries. The VLR metric tracks the absolute number of SIM cards actively making calls, sending data packets, or registering on tower cell sites at any given peak window.
According to the TRAI telecom data May 2026 report, the stark operational divergence between India’s top three private service networks highlights a structural multi-tier market:
| Telecom Service Provider | Gross Wireless Base (May 2026) | Active VLR User Base (May 2026) | Active VLR Proportions | Sequential Active Change |
| Reliance Jio | 501.44 million | 495.56 million | 98.83% | +3.10 million |
| Bharti Airtel | 483.81 million | 480.33 million | 99.28% | +0.82 million |
| Vodafone Idea (Vi) | 198.66 million | 167.69 million | 84.41% | -1.58 million |
| BSNL | 92.91 million | 51.90 million | 55.85% | -0.13 million |
Why the Active Base Erosion Weakens Vi’s Turnaround Plan
The continuous drop in Vodafone Idea active users undercuts the near-term benefits of the carrier’s recent positive financial milestones. While the operator recently celebrated a fresh ₹1,182 crore equity warrant injection from the Aditya Birla Group, generating immediate liquidity, losing high-value users limits its structural recovery.
The Low-Value M2M Dilemma
Recent exchange data reveals a challenging operational trend: the bulk of Vi’s gross subscriber additions are coming from the Machine-to-Machine (M2M) and low-end enterprise IoT segments rather than individual retail smartphone connections. While these corporate tracking chips help pad gross connection figures on paper, they yield a significantly lower Average Revenue Per User (ARPU) compared to premium human mobile connections.
Excluding these low-yield automated nodes, Vi’s consumer cellular division faced an accelerated retail churn during May, pushing thousands of active, standard data accounts toward Jio and Airtel.
Impact on Banking and Funding Lines
This underlying subscriber erosion could stall the management board’s ongoing discussions with major financial consortiums. As the company works to structure its multi-year ₹1 lakh crore modernization pool, institutional lenders use long-term active VLR stability as a key metric for risk evaluation.
If active users continue to leave the network faster than the company can raise its overall pricing floor, the business faces an unsustainable trajectory where revenue generation cannot naturally support massive infrastructure upgrades.
How many active users did Vodafone Idea lose in May 2026?
According to official TRAI data, Vodafone Idea’s active user base fell by 1.58 million lines, dropping from 169.27 million in April to land at 167.69 million by the end of May.
What is the difference between gross and active subscribers in TRAI reports?
Gross subscribers include every SIM card officially registered on a network, including inactive or dormant accounts. Active subscribers are calculated via the peak Visitor Location Register (VLR), which measures the exact number of connections actively interacting with the network.
How does Vi’s active user percentage compare to Jio and Airtel?
Vodafone Idea currently operates with an 84.41 percent active user base. In contrast, competitors Bharti Airtel and Reliance Jio run highly optimized networks, with active user ratios near maximum capacity at 99.28 percent and 98.83 percent, respectively.
Did BSNL add active users during this tracking cycle?
No. State-run BSNL also posted active user losses during the month, with its active VLR connection base slipping down to 51.90 million lines, which represents just 55.85 percent of its gross registered customer base.
Conclusion
The latest indicators from TRAI highlight that the core operational challenge facing Vodafone Idea is a matter of subscriber quality rather than network scale. While generating fresh corporate funding and adding gross machine-to-machine connections keeps the company stable on paper, the ongoing erosion of its active user base remains a persistent structural hurdle. With both Reliance Jio and Bharti Airtel consistently capturing high-value users and maintaining near-perfect active ratios, Vi’s absolute priority must shift toward protecting its core retail user base. Halting active subscriber churn is critical if the company hopes to convert its current fundraising plans into sustainable, long-term market growth.
