Sinch

Sinch specializes in cloud communications for enterprises with strong focus on CPaaS and direct carrier connections. Its Verify and Conversational Messaging products cover OTPs and alerts. Compared with Termii, Sinch provides deeper telecom integrations and global scale but less emphasis on AI-driven prevention of failed fraud checks. Pricing structures favor large deployments. Payment processors needing both messaging and rich carrier data often consider Sinch alongside or instead of Termii.
