Bulk SMS pricing in Kerala
Bulk SMS is pay-as-you-go. You buy credits and pay per message, and the rate drops as your volume grows, with no setup fee and no monthly rental.
Transactional, OTP and promotional routes are each priced per SMS, and a longer message counts as more than one SMS. Every payment comes with a GST invoice.
See current rates on our pricing page, or talk to us about volume pricing for high-traffic senders.
Bulk SMS in Kerala cities
Dedicated coverage for the state's major business hubs, with the same panel, API and pricing everywhere.
We also serve businesses in Kozhikode, Thrissur, Kollam, Kannur and Alappuzha, and across Malabar, central Kerala and the backwater belt.
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 Kerala 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.

SmsHorizon serves businesses pan-India, with dedicated coverage for other states too.
