How we got this number

  1. Collect provider prices from two independent comparisons (May and August 2026).
  2. Note where they disagree: MSG91 at ~₹0.15 in one and ₹0.18–0.25 in the other, which says list prices move with volume and deal.
  3. Take ₹0.15 to ₹0.25 as the best guess for a startup at small volume and the full ₹0.10 to ₹0.45 as the range.

What this number does not tell you

  • One of the two comparisons is written by a provider that sells OTPs, so its competitor prices are its estimates.
  • DLT registration and sender approval add one-time cost and time.
  • Failed deliveries may or may not be billed, depending on the provider.
