Bulk SMS service provider in Kerala - SmsHorizon

Bulk SMS service across Kerala

Kerala runs on connected, mobile-first customers, and businesses here lean on timely text messages every day. A bank in Kochi sends OTPs to an NRI customer, a resort in Kovalam confirms a booking, a college in Thrissur shares exam results, all over SMS.

You can cover Kochi, Thiruvananthapuram, Kozhikode, Thrissur, Kollam and the rest of the state from a single account. Full Malayalam Unicode lets you message people in the language they read every day, a real edge for reaching customers across Kerala.

Cities we serve

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.

Other states we serve
