After registering, use your registered mobile number to request an OTP. Navigate to the OTP generation section, enter your registered mobile number, and click "Generate OTP." The OTP will be sent to the mobile number you used for registration via SMS. Please ensure your mobile device is active and has network connectivity.

Confirm that you have registered with the correct mobile number. Sometimes, there might be a slight delay in receiving the OTP. Wait for a few minutes, and if the issue persists, attempt to resend.
