Built for developers who just want the SMS to arrive

  • All four operators

    Unitel, Mobicom, Skytel and G-Mobile behind one endpoint. We route by number prefix; you never pick an operator.

  • OTP built in

    POST /v1/otp sends a code, /v1/otp/check verifies it. Hashed codes, attempt limits and per-number rate limits.

  • Signed webhooks

    Standard Webhooks signatures, retries for 32 hours, resend and secret rotation from the dashboard.

  • Test keys with magic numbers

    sk_test_ keys run the full pipeline for free. 00000000 delivers, 00000001 fails, 00000002 times out.

  • Cyrillic-aware pricing

    See encoding and segments before you send. One flag transliterates Mongolian to Latin and cuts segments by more than half.

  • Node SDK and CLI

    @smsmulti/sdk with retries and idempotency, and smsmulti listen to forward events to localhost.

50₮ per segment. That is the whole price list.

Prepaid balance, no monthly fee. A Latin SMS fits 160 characters per segment, Cyrillic 70. Failed, expired and canceled messages are refunded. Optional daily and monthly spend caps per project and per key.
