Tanla (Karix) review and pricing

Indian-origin CPaaS controlling a meaningful share of India A2P SMS volume.

By Tanla Platforms Limited · Founded 1999 · Hyderabad, India · public

Tanla Platforms (NSE/BSE: TANLA) is the Indian-origin CPaaS founded in Hyderabad in 1999 and listed on Indian exchanges. The business controls a meaningful share of Indian A2P SMS volume routed through Indian operator networks (Vodafone Idea, Airtel, Jio, BSNL), powered by the proprietary Trubloq blockchain-anchored DLT-routing platform that scrubs SMS templates and senders against TRAI DLT registrations natively. Karix Mobile, the legacy India CPaaS business previously owned by GSO Capital and earlier by Globe Telecom, was acquired by Tanla in 2021 — consolidating the largest Indian A2P SMS positions under one roof. For India-bound A2P SMS at carrier-grade volume, Tanla and Karix are the default Indian-origin choices; for international traffic, US-anchored vendors typically still win on global routing breadth.

Best for
