Under TRAI rules, business SMS sent to Indian numbers over domestic routes must be registered on an operator DLT (Distributed Ledger Technology) platform. OTP messages are no exception: the sender, the sender ID and the exact message wording are all registered before traffic can go live.
On EazyOTP, the DLT SMS route (smseazyotp) carries this registered traffic. If you need to launch before approval comes through, the Global SMS route delivers to Indian numbers without a DLT template or sender ID.
