About Us

Many interactive websites or e-commerce platforms require mobile number verification as identity authentication. 

There are a few common ways to verify the mobile number. 
1. SMS:  Mostly used method is sending verification code to user’s registered mobile and check  user’s return.
    It is fast and convenient. However, the more users, the higher SMS cost. 
2. Inbound voice OTP:  System calls the registered number and plays a voice verification code, the user enters it back to website. System will pay for the verification call. 
3. Outbound voice OTP : User dials the system number via registered mobile and gets the verification code, then enters it back to website. User will pay for the verification call. 
24x7 provides ideal and secure solution for both user and platform side. 
Connect the verification device with landline and network. When user calls the system number via registered mobile number, the device will send  user’s Called ID to web server for verification with user’s profile. Without answering the call, the verification procedure will be completed. The process is totally free of charge on either user or platform.
