Does the OTP route vary between Transactional and Promotional SMS?

Yes, OTP (One-Time Password) delivery uses a dedicated Transactional route, not Promotional. Transactional SMS, including OTPs, are sent via high-priority channels for instant delivery, available 24/7, and exempt from DND restrictions (e.g., “Your OTP is 123456 -SMSGAT”). Promotional SMS, restricted to 9 AM – 9 PM and blocked for DND numbers, aren’t suitable for OTPs due to delays and compliance rules. SMSGatewayCenter ensures your OTPs reach fast via our Transactional SMS gateway.
