Best Cloud Communication Platform in India | Communication Platform as a Service - MSG91
About This App
MSG91 is a cloud communication platform founded in 2010 by Walkover Web Solutions in Indore, India. It provides APIs for SMS, email, WhatsApp, voice, and OTP verification that businesses integrate into their apps and workflows. The platform processes 2.5 billion+ monthly API calls and serves over 30,000 customers across 192 countries โ including Indian brands like Razorpay, PolicyBazaar, MakeMyTrip, Ixigo, 1MG, Barista, NTPC, and Mahindra. MSG91's core strength is its developer-friendly API suite โ SendOTP for phone verification, transactional SMS with DLT compliance built in, WhatsApp Business API at Meta's official rates, email delivery, and voice calls โ all from a single dashboard with unified analytics. The platform includes serverless tools like Hello (customer support chat), Campaign (bulk messaging), Segmento (audience segmentation), ShortURL, and KnowledgeBase. DLT registration support is a significant advantage for Indian businesses navigating TRAI's regulatory requirements. Pricing follows a prepaid wallet model โ add funds and consume credits across all channels. SMS starts at Rs 0.25/message, WhatsApp at Meta's official rate of Rs 0.78/marketing message with a Rs 500/month subscription per number (waived for first 2 months). No monthly commitments, no hidden fees โ you pay only for what you use. Compare this to Twilio's dollar-denominated per-message pricing and MSG91 is significantly cheaper for Indian SMS/OTP volume. Best suited for Indian developers and businesses that need reliable transactional messaging (OTP, order confirmations, alerts) at scale with INR billing and DLT compliance built in. Enterprises needing a global omnichannel platform with advanced call center features may find Twilio or Vonage more feature-complete, though at 3โ5x the cost for Indian traffic.
