Bulk SMS Cost Calculator India 2026

Bulk SMS in India costs from ₹0.10/SMS (promotional, 5 lakh+ volume on SMSGatewayHub) to ₹0.55/SMS (Twilio, USD-billed). Standard rates: promotional ₹0.12/SMS (up to 1L), transactional ₹0.18/SMS (up to 1L), OTP ₹0.18/SMS (up to 1L). Volume slabs reduce rates significantly — SMSGatewayHub reaches ₹0.10/SMS at 5L promotional and 10L transactional/OTP. All prices exclude 18% GST.

The cheapest OTP SMS rate in India at volume is ₹0.10/SMS (SMSGatewayHub, 10 lakh+ per month on the dedicated critical route with sub-2-second delivery and 99.9% uptime). At standard volumes (up to 1 lakh), OTP SMS costs ₹0.18/SMS on SMSGatewayHub. Fast2SMS claims lower rates but is not recommended for OTP-critical or BFSI use cases by independent reviewers.

Yes at all volume levels. At 1 lakh/month: SGH ₹12,000 vs MSG91 ₹13,000+ (save ₹1,000/month). At 5 lakh/month: SGH ₹55,000 vs MSG91 ₹60,000+ (save ₹5,000/month). At 10 lakh/month: SGH ₹1,00,000 vs MSG91 ₹1,20,000+ (save ₹20,000/month = ₹2.4 lakh/year). SGH also offers SMPP connectivity and ISO 27001 certification which MSG91 doesn't provide.

No. All published bulk SMS prices in India are exclusive of 18% GST. Toggle the GST option in the calculator above. Example: 1 lakh SMS at ₹0.12 = ₹12,000 base + ₹2,160 GST (18%) = total ₹14,160. SMSGatewayHub invoices clearly split base amount and GST component — suitable for GST input credit claims by registered businesses.

Twilio bills in USD — India SMS costs approximately $0.005–$0.007 per message which at current USD/INR (≈84) equals ₹0.42–₹0.59/SMS. Add 18% GST on top. That's 3–5x more expensive than Indian providers like SMSGatewayHub. Twilio also doesn't have native TRAI DLT compliance support — requiring significant manual setup for Indian businesses, adding further hidden cost.
