We are always happy to discuss any of your requirements.
Trusted by 5,000+ businesses across India. Our transactional SMS gateway delivers OTPs in under 6 seconds — with a free API, 99.9% uptime, and pricing that actually makes sense. No credit card needed to get started.
Every time a user logs in, makes a payment, or activates an account on your platform, they're waiting for that one SMS. If it doesn't arrive instantly, you lose them. That's the problem we solve.
MetaReach runs a dedicated OTP SMS gateway with direct SMPP connections to Airtel, Jio, and Vi — so your OTPs are never queued behind promotional traffic. We handle DLT registration, sender ID setup, and template approvals so your team can focus on building, not compliance.
From startup apps running a few hundred OTPs a day to enterprise platforms sending millions a month, our infrastructure scales with you. And if something goes wrong — which is rare — our technical team actually picks up the phone.
Here's what actually matters when choosing an OTP provider — and what sets MetaReach apart from generic SMS aggregators.
SMS OTP verification ensures only the account holder can approve a login or transaction. It's a simple layer that blocks most account takeover attempts — especially important for fintech, banking, and healthcare platforms.
Our dedicated OTP routes are separate from promotional SMS traffic. Your messages hit the network instantly — average delivery is 2 to 6 seconds, so users aren't left staring at a blank screen waiting for their code.
SMS reaches every mobile in India — feature phones, 2G connections, every operator. Unlike app-based authenticators, SMS OTP works for 100% of your user base without any additional setup on their end.
Our SMS pricing is straightforward — no monthly fees, no hidden charges, no confusing credit structures. Pay for what you send, with volume discounts as you scale.
India has over 900 million mobile users across every type of device and network. Our gateway has direct relationships with all major operators, so delivery rates remain high even in low-connectivity areas.
Adding OTP verification to every transaction or login makes unauthorized access exponentially harder. For e-commerce and banking clients, this alone often justifies the cost — fraud losses consistently outweigh SMS costs.
TRAI's DLT registration is mandatory for all commercial SMS in India. We handle entity registration, sender ID creation, and template approvals — at no extra cost, typically within 48 hours.
Slow or failed OTPs cause users to abandon sign-up flows and payment pages. Reliable, fast SMS delivery directly improves your conversion rates — something our clients notice within the first week of switching to MetaReach.
Our REST API is clean and well-documented, with ready-made code samples in PHP, Python, Node.js, Java, and .NET. Most developers complete basic integration in well under an hour. View the full API docs →

An OTP SMS service delivers a One-Time Password to a user's mobile number whenever they need to verify their identity — for login, payment, registration, or any sensitive action. The OTP arrives as a standard SMS, works on every mobile regardless of internet connectivity, and typically expires within a few minutes. As a DLT-approved transactional SMS gateway, MetaReach sends these OTPs via dedicated routes — average delivery is 2 to 6 seconds, any time of day.
Transactional SMS — which includes OTPs — is sent for essential, non-marketing purposes: authentication, payment alerts, order confirmations, account notifications. It can be sent to DND numbers at any time, 24/7/365. Promotional SMS is for marketing offers and can only reach non-DND numbers between 9 AM and 9 PM. OTP and transactional messages always take the transactional route, which means they bypass DND restrictions entirely and have no time-of-day limits. Read our full guide on OTP vs normal SMS differences.
Yes — sign up and you'll get API access and trial credits immediately, with no credit card required. This isn't a sandbox with fake delivery; you can send actual SMS to real numbers and test the full flow. For production volumes, pricing is flexible: pay-as-you-go for low or unpredictable volumes, and discounted bulk packs if you're sending consistently. Visit our pricing page for current rates, or call us for a custom quote on high-volume requirements.
It's a standard REST API — your backend makes a POST request with the recipient's mobile number, your approved sender ID, and message template. Our gateway validates the request and dispatches the OTP within milliseconds; the user receives it in 2–6 seconds. We have ready-made code samples in PHP, Python, Node.js, Java, and .NET, plus a Postman collection. For most developers, basic integration takes under 30 minutes. Full API documentation is here.
2FA (two-factor authentication) adds a second verification step after the user enters their password. An OTP is sent to their registered mobile; they enter it to complete login. Our platform supports the full 2FA workflow via the same REST API. We also support voice OTP as a fallback — if an SMS can't be delivered, the system can call the user and read the code aloud, ensuring virtually zero verification failures.
Yes — we manage the entire DLT registration process on your behalf at no extra charge. This covers entity registration on the TRAI portal, sender ID assignment, and OTP template approvals.
