This particular extension will send a short code to the mobile number and validate the mobile number entered at the time of registration. This will work as an addon component that will work on top of JEEMA SMS.
Member register in your website by entering their mobile number. This extension will send a validation code to the mobile number. When the member login again it will ask to input the validation code. Once valid code entered it will allow the member to login.
This will use JEEMA SMS to send SMS messages. So JEEMA SMS is mandatory to make this extension to work.
