Twilio SMS Gateway Integration

How It Works

Spotipo's Twilio SMS gateway integration enables phone-based WiFi authentication, delivering one-time passwords via SMS for secure, passwordless guest network access.

Passwordless authentication. Replace traditional email/password logins with SMS-based one-time codes, reducing friction and improving WiFi access completion rates.

Phone number verification. Capture and verify real phone numbers at WiFi login, building high-quality contact lists for SMS marketing campaigns.

Global SMS delivery. Twilio's worldwide carrier network ensures OTP codes reach guests reliably across 180+ countries and 1,000+ mobile carriers.

Fraud prevention built-in. SMS verification prevents fake accounts and bot registrations, ensuring your WiFi user database contains genuine, reachable contacts.

Customizable message content. Personalize SMS authentication messages with your brand name, custom sender ID, and multilingual content for international guests.

Real-time delivery tracking. Monitor SMS delivery status, failed messages, and carrier response codes through integrated dashboards for troubleshooting and optimization.
