We originally started using Dexatel for SMS verification, but what really made the platform stand out was its whatsApp OTP capability. Afyer comparing several Best WhatsApp Providers for user verification, Dexatel offered the right balance of reliability, simplicity, and pricing. The integration process was smooth, and we were able to activate whatsApp OTP without redesigning our entire authentication flow. Delivery rates improved noticeably in regions where traditional SMS delivery was inconsistent,. I also appreciate that the platform supports multiple communication channels from a single dashboard, which makes operations much easier for our team. Another thing I genuinely like is that Dexatel feels focused. Instead of overwhelming users with unnecessary complexity, it concentrates on doing communication and authentication well. Their APIs are practical, documentation is clear, and onboarding was faster than with previous providers was tested

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
