SmsHorizon Transactional SMS review
A prepaid India-focused SMS service with delivery reporting, webhooks, and DLT assistance.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SmsHorizon Transactional SMS is a cloud service for businesses sending OTPs, alerts, and notifications in India. Teams can send individual or bulk messages through a web panel or REST/HTTP API, making it relevant to developers as well as operators who prefer a browser interface. It is suited to small, mid-market, and enterprise teams that need transactional messaging, regional-language support, and delivery status visibility; it is less suited to buyers seeking a free plan or a recurring monthly subscription.
Pricing is based on prepaid SMS-credit packages shared by transactional and promotional SMS, rather than recurring monthly plans. The Professional package is INR 2,000 for 10,000 SMS at 20 paise per SMS; Business is INR 4,500 for 25,000 at 18 paise each; Premium is INR 8,000 for 50,000 at 16 paise each; and Enterprise is INR 14,000 for 100,000 at 14 paise each. These options make the per-message rate clear across volume tiers, while requiring teams to choose and pay for a bundle upfront.
The API returns JSON and uses bearer-token authentication, and webhook callbacks provide message-status changes alongside reports for sent, delivered, and failed messages. Priority routing across Airtel, Jio, and Vodafone Idea, Unicode messaging in 15+ Indian languages, and DLT registration assistance address practical needs for India-focused messaging. Integrations include PHP, Node.js, Python, Java, .NET, Ruby, WordPress, WooCommerce, Shopify, Zapier, and Make. Choose SmsHorizon when these India-specific messaging functions and prepaid volume bundles fit the workflow; consider an alternative if free access or a monthly subscription is essential.
