1. Regulatory focus
The amendment changes operators’ Special Tariff Voucher offerings: each validity period of 30 days or less available for a voice, SMS, and data bundle must have a corresponding voice-and-SMS-only option with an appropriate tariff reduction. Operators must also offer calendar-month renewal, using the final day when the corresponding renewal date does not exist, plus at least one longer-validity option corresponding to a bundled offering. These requirements concern the availability and duration of consumer recharge products; they should not be presented to enterprise customers as a mandatory reduction in A2P SMS gateway or termination charges.

2. Business impact
TRAI identified limited availability of voice-and-SMS-only vouchers, concentrated in longer validity periods, as the problem behind the amendment. ([trai.gov.in](https://www.trai.gov.in/sites/default/files/2026-09/PR_No120of2026.pdf)) Our operational recommendation is for recharge platforms and distributors to check whether their catalogs still expose only long-duration options, with validity, SMS allowances, and data entitlements stored as separate product attributes rather than inferred from a plan name. Account-verification teams can add a no-mobile-data scenario to their test matrix, but should not treat the amendment as evidence that OTP delivery, inactive-number handling, number retention, or incoming-message eligibility has changed; those questions require separate operator confirmation.
3. Operating recommendations
Build an operator-by-operator comparison table containing bundled-plan validity, the corresponding voice-and-SMS-only product, price, SMS allowance, and listing date, then validate short-duration, calendar-month, and longer-validity options separately. Add month-end test cases and keep 28-day rolling validity distinct from renewal on the same calendar date each month, rather than treating both as a generic monthly product. For support scripts, require operator confirmation before promising automatic payment, indefinite OTP reception, or service continuity after expiry, and retain the underlying product terms with each catalog update. These are implementation checks proposed for distributors and product teams, not additional statutory reporting obligations.
