India's three largest mobile operators – Bharti Airtel, Reliance Jio and Vodafone Idea – must offer voice and SMS-only tariffs from 21 October 2026, after regulator TRAI pressed ahead with a consumer-protection mandate that all three formally opposed.

The Telecom Regulatory Authority of India has ordered the operators to make affordable data-free plans available by that date, targeting low-income users who need short-term, flexible calling and messaging options but have little use for bundled data.

Under the mandate, operators must provide Special Tariff Vouchers (STVs) for voice and SMS with validity periods of up to 30 days and monthly renewal options. Each operator must also offer at least one longer-validity plan covering voice and SMS alone.

This is TRAI's second attempt to fix the problem. In December 2024, the regulator required every operator to offer at least one voice and SMS-only STV. The result fell short: operators offered limited validity options and did not reduce prices to reflect the removal of data, which effectively made voice and SMS plans less available. The new mandate addresses this by requiring parity across validity periods.

All three operators formally objected to the directive, arguing it was anti-consumer. Jio went furthest, claiming that voice now functions as an application running on an underlying data network, making voice-only plans technically infeasible. The operator also pointed out that 88% of its subscribers are active data users.

TRAI acknowledged the objections but proceeded regardless. The regulator's position is that users who do not need data should be able to buy plans with the same validity periods as data tariffs, but at proportionally lower prices.

The dispute cuts to a structural question in modern networks: whether voice remains a separable retail product when operators have moved to all-IP architectures where calls ride over data infrastructure. Jio's argument frames the mandate as a technical impossibility; TRAI treats it as a commercial choice that regulation can override in the interest of price-sensitive subscribers.

For Airtel, Jio and Vodafone Idea, the compliance burden is modest in engineering terms but potentially awkward commercially. Each must now price voice and SMS plans in a way that visibly reflects the absence of data, creating a direct comparison with bundled tariffs that could expose how much of current plan pricing covers data services.

The 21 October 2026 deadline gives the operators time to design voucher structures that meet the validity-parity requirement, and the market will see within months of launch whether the new STVs deliver meaningful savings for non-data users or repeat the thin uptake that followed the December 2024 mandate.
