Bulk SMS with quick DLT setup.
Fast2SMS is a prepaid bulk messaging service run by SID Groups Private Limited. It says it has been in business since 2011. It sells DLT bulk SMS, OTP SMS, a developer SMS API, voice calls, RCS and the official WhatsApp Business API from one wallet. The usual buyers are small Indian businesses, coaching institutes, local retailers and app developers. They want to send promotional or transactional SMS without signing an annual contract with a large CPaaS vendor.
Pricing is pay-as-you-go and easy to understand. You add money to the wallet from Rs 100, and the per-SMS rate falls with the size of the recharge. It starts at Rs 0.25 per SMS for recharges up to Rs 3,999, with unlimited validity, and drops to Rs 0.11 for recharges of Rs 6 lakh or more, valid for 24 months. Fast2SMS says the same rate applies to promotional, transactional, service, OTP and API SMS. Voice calls cost Rs 0.10 per 15 seconds. On WhatsApp, utility and authentication messages cost Rs 0.25, marketing messages Rs 0.95 and session messages Rs 0.13, with no setup or monthly fee.
TRAI rules apply. To send bulk SMS in India you must register your entity, sender ID and templates on a DLT portal, then link them to Fast2SMS. For teams that have not finished DLT, the 'Quick SMS' route sends without registration, but each message is approved by hand, so it suits occasional sends rather than OTPs. New accounts get Rs 50 of free credit to test delivery.
The weak spots are mostly about information. The pricing pages do not say whether GST is included, and the help centre is thin on refunds, support hours and invoicing. Integrations are limited too: there is a WordPress and WooCommerce plugin, a Google Sheets add-on and an Android app, but you won't find a broad CRM marketplace. If you need campaign analytics, multi-channel journeys or an enterprise SLA, a larger CPaaS provider is the safer choice.

Fast2SMS charges Rs 0.25 per SMS for wallet recharges between Rs 100 and Rs 3,999, and the rate drops in slabs to Rs 0.11 per SMS for recharges of Rs 6 lakh or more. The same rate applies to promotional, transactional, service, OTP and API messages. Validity runs from unlimited on the smallest slab to 24 months on the largest.
The Fast2SMS SMS and WhatsApp pricing pages do not say whether GST is included or added on top. Since 18% GST on Rs 0.25 changes your real cost noticeably at volume, confirm this with Fast2SMS support before a large recharge and ask how tax invoices are issued.
Yes. Fast2SMS gives Rs 50 of free credit after sign-up so you can send test messages and check delivery reports. That is about 200 SMS at the Rs 0.25 rate. After that you need to recharge the prepaid wallet, which starts at a minimum of Rs 100.
For bulk SMS in India, yes. TRAI rules require you to register your business, sender ID and message templates on a DLT portal, and you then link them in Fast2SMS. Fast2SMS also offers a Quick SMS route that works without DLT, but every message is approved manually, so it is not suitable for OTPs.
Fast2SMS charges Rs 0.25 per utility or authentication message, Rs 0.95 per marketing message and Rs 0.13 per session message on the official WhatsApp Business API. It states there is no setup or monthly fee, billing is per delivered message, and the wallet can be started with Rs 100.
Yes. Fast2SMS offers an OTP SMS API and a general bulk SMS API at docs.fast2sms.com. You authenticate by sending your API key, generated free in the Dev API section, in the Authorization header, and call the bulkV2 endpoint with GET or POST. Code samples cover PHP, Python, Java, C#, Ruby and Node.js.
Fast2SMS has an Android app on Google Play (package com.fast2sms.android). It can import contacts from your phone, collect contacts through a shared QR link, and send or schedule bulk SMS. Registration uses your mobile number and an OTP. An iOS app is not mentioned on the Fast2SMS help pages.
Fast2SMS suits small senders who want published slab rates, a Rs 100 entry point and a simple panel. MSG91 is the stronger pick for product teams that want broader CPaaS features, more SDKs and enterprise support. Compare actual delivered cost, including GST, on your own traffic before committing large recharges to either one.
Yes. Fast2SMS has a WordPress and WooCommerce plugin with a setup guide in its help centre, and a free Fast2SMS for Google Sheets add-on on the Google Workspace Marketplace that sends SMS from spreadsheet rows through its API. For other software you would connect through the REST API yourself.
Fast2SMS says it has direct operator connectivity with Airtel, Vi, Jio and BSNL and routes traffic over multiple SMS routes for faster delivery. It also lists ISO, SOC and VAPT certifications on its homepage. Delivery reports are available in the panel and through webhooks for API users.
