We have been in business since 2011. Reach us on +91 8870-522-522 or via our contact page.

Q: Can I send SMS in Assamese?

Yes. We support full Assamese Unicode, so you can send messages in Assamese to your customers across Guwahati and Assam. Set the message type to Unicode in the panel or pass uni in the API.

Q: Is your API built for high-volume OTP and 2FA?

Yes. Our HTTP and SMPP APIs are built for high throughput, with priority transactional routing, sub-3-second OTP delivery and detailed delivery reports.

Q: How quickly can a Guwahati business go live?

Typically 3 to 5 days. Most of that time is the DLT registration and sender ID approval, which we handle for you. Once those clear, your account is ready and you can send your first campaign or wire up the API right away.

Q: Do you help with DLT registration?

Yes, free of charge. TRAI requires entity, header and template registration on the DLT portal for all commercial SMS. Our team walks you through the entire process and handles the paperwork.

Yes. Pay by UPI, card, netbanking or bank transfer, and we issue a GST invoice for every payment, with the same transparent pay-as-you-go pricing we offer everywhere.

Q: How much does bulk SMS cost in Guwahati?

Bulk SMS is pay-as-you-go: you pay per message and the rate falls as your volume grows, with no setup fee or monthly rental. Transactional, OTP and promotional routes are each priced per SMS, and a longer message counts as more than one SMS.

Q: Which mobile networks do you cover in Guwahati?

We deliver across every major network, including Jio, Airtel, Vi and BSNL, over direct operator routes. Transactional and OTP messages reach all numbers, including DND, while promotional sends follow TRAI's DND rules and the 10am to 9pm window.
