Important Awareness Notice

Don't be fooled by fake SMS companies. Many new as well as few established companies sell SMS at very low cost, below the industry standard — here's the trap behind it. Delivery Cut-Off System: if you buy 1 lakh SMS at 5 paisa and send all of it, such providers submit only 50% (or less) to the SMSC for delivery and update fake delivery reports. Please stay away from those companies; we're committed to industry-best service & support at a competitive, lowest-possible price.

How we're different: you never pay for an OTP that isn't delivered
🔄 Auto-refund, no ticket needed 📊 Real-time delivery reports 🔒 Nothing to fake — we don't get paid unless it's delivered

Our billing model settles your wallet only when the carrier confirms delivery — every Failed, Expired, Undelivered or Rejected SMS is refunded automatically. Since we don't get paid on undelivered messages, there's no incentive to inflate delivery reports the way the companies above do.

Choosing the right verification method

OTP SMS vs Missed Call Verification

OTP SMS runs on a dedicated, high-priority route separate from Promotional and Transactional traffic — it isn't affected by DND rules or the TCCCPR delivery-window changes. If you're verifying very high volumes, Missed Call Verification is worth comparing too.

OTP SMS This page

One-time verification codes delivered via SMS in under 4 seconds on live numbers, on a dedicated priority route with multi-operator routing across Airtel, Vi & Smartping. Works on DND numbers.

Missed Call Verification

Authenticate a user through a toll-free missed call instead of an SMS — a zero-SMS-cost alternative that suits very high-volume login/verification flows.

Common questions

OTP SMS pricing, explained

What does "Lifetime Validity" mean for OTP SMS credit?

Effective 1st September 2026, SMS credit purchased on any OTP route pack no longer expires after a fixed 1-year or 3-year period. Your unused balance stays valid for as long as your account remains active, with no forced renewal or credit forfeiture.

I purchased a pack before 1st September 2026 — does Lifetime Validity apply to my existing balance too?

Yes. Lifetime Validity applies to OTP SMS credit balances from 1st September 2026 onward, including unused credit carried over from packs bought earlier under the previous 1-year or 3-year validity terms.

What is Multi-Operator Priority Routing for OTP SMS?

OTP traffic is routed through dedicated high-priority connections across major operators, including Airtel, Vi and Smartping, so verification codes reach users reliably even during peak network congestion.

How fast is OTP SMS delivery?

On live, DLT-compliant routes, OTP SMS typically delivers in under 4 seconds on live numbers, since OTP traffic runs on a dedicated priority route separate from Promotional and Transactional SMS.

Does OTP SMS work on DND (Do Not Disturb) numbers?

Yes. OTP SMS is a Transactional message type used purely for user-initiated verification, so it is delivered to DND-registered numbers as well.

Is there an alternative to SMS-based OTP?

Yes. Missed Call Verification lets you authenticate a user through a toll-free missed call instead of an SMS, which can reduce cost for high-volume verification flows.

What is the DLT scrubbing charge shown in the pricing?

A statutory DLT scrubbing charge of ₹0.025 per SMS is included in all bundle prices, as mandated under TRAI's DLT framework. This is an industry-wide regulatory charge, not an SMSGatewayHub markup.

Do I need DLT registration before sending OTP SMS?

Yes. TRAI requires every business to register its entity, sender headers, and OTP templates on the DLT platform before sending OTP SMS. Our team assists with DLT registration end-to-end.

Is GST included in the listed price?

The per-SMS rate and base Amount are shown exclusive of GST. The adjacent figure marked "Inclusive 18% GST" is the final amount you pay.

Can I integrate OTP SMS with my app or website?

Yes. Plug-and-play OTP SMS APIs are available with sample code across all major programming languages, so you can go live with 2FA or user verification in minutes.
