Global SMS Coverage
Reliable OTP delivery to mobile networks worldwide
SMS-OTP works in over 200 countries. Mideye maintains direct connections with mobile networks globally to help one-time passwords arrive quickly and reliably — regardless of where the user is traveling. For faster authentication in connected environments, consider Mideye+ push notifications instead of SMS.
How Does SMS-OTP Delivery Work?
Direct carrier connections mean faster delivery and higher reliability than aggregator routes.
Why Do Direct Connections Matter?
⚡ Faster Delivery
Direct routes to carriers mean fewer hops. Most OTPs arrive within seconds, not minutes.
✅ Higher Reliability
Bypass congested aggregator networks. Direct connections have better delivery rates. For troubleshooting SMS delivery issues, see our mobile phone user guide.
When SMS Isn't Enough
For users who travel frequently or work in areas with poor mobile coverage, Mideye offers alternatives:
- Mideye+ App: Push notifications over WiFi + offline OTP generation
- Hardware Tokens: Physical OTP devices for air-gapped environments
- TOTP Apps: Standard authenticator apps (Google Authenticator, etc.)
