OTP
Critical messaging with SIM-change checks, built for financial institutions.
OTP is a messaging service with a very high delivery guarantee that checks, before sending, whether the SIM card has changed in the last 90 days. This check is open only to financial institutions, so OTP is used only by payment, crypto and investment institutions and by banks. Its unit cost is higher than FastSMS, which does not include the SIM check.
Who Is It For?
- Payment and electronic money institutions
- Crypto asset service providers
- Investment and brokerage firms
- Banks
Why OTP (instead of FastSMS)?
FastSMS is enough for one-off notifications such as password resets, alerts and access codes. For the most critical steps, such as confirming a payment, extra protection against SIM swap fraud is a legal requirement in the banking and finance sector: OTP does not send to numbers whose SIM was changed in the last 90 days.
Cloud or On-Premise?
Both delivery models include the same OTP service; the difference is the infrastructure.
