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.

DLT registration and compliance, handled for you

Every commercial SMS in India must go through DLT, the TRAI-mandated registration on a blockchain platform. It covers your business entity, your sender IDs (headers) and the message templates you send.

For a business in Assam getting started, this is usually the only real hurdle. Our team registers your entity, headers and templates for you, free of charge, and keeps you compliant as you add new message formats.

Once registration clears, most accounts are live within 3 to 5 days. From there you send from the web panel or the API, with a GST invoice on every payment.
