About Fast2SMS
Fast2SMS is an Indian bulk SMS provider run by SID Groups since 2011. Businesses, schools and developers use its web panel or API to send promotional and transactional SMS, one-time passwords, voice calls, RCS messages and WhatsApp Business messages to Indian numbers. It handles the TRAI DLT rules that govern commercial SMS in India: you connect your approved sender ID and content templates, then send through the panel or API. For those who haven't completed DLT registration, a Quick SMS route uses an international gateway with each message approved manually. Pricing is prepaid: you top up a wallet and pay per SMS, with the rate falling as the recharge amount grows and validity periods attached to larger packs. New accounts get a small free credit to test delivery. It is built for the Indian market only, so it isn't a choice for global messaging, and its API and documentation are simpler than those of the big international CPaaS platforms.
Best for: Indian businesses and developers who need cheap bulk SMS and OTPs to Indian numbers.
