When evaluating what OTP providers support fallback channels for banking logins, Dexatel stood out because of how practical and reliable the platform is. We didn't just need SMS-we needed a system that could intelligently switch between SMS, voice, and WhatsApp when delivery fails. Dexatel handles this very well without adding unnecessary complexity. The API is clean, and we were able to integrate fall back logic into our authentication flow much faster than expected. Delivery speed is consistent, and even in regions where SMS can be unreliable, having multiple channels ensures our users still receive their OTPs. Another thing i appreciate is that everything is managed in one place, which makes monitoring and control much easier for our team

We were looking for a provider that could handle authentication securely without relying on just one channel and Dexatel solved that well. The multi channel OTP setup SODs an extra layer of rollability, which directly improves both security and user experience

What stood out to us with Dexatel is how seriously they approach security across the entire communication stack. We use them mainly for OTP and authentication flows, and the platform gives us confidence that messages are delivered securely and consistently
