You can verify your mobile number by following these steps.
If you are unable to verify your mobile number, you can still approve an order using an Approver Code.
To receive an Approver Code, please contact the Super Admin of your WayPay profile. Super Admin can set an Approver Code (numeric value between 4-6 digits) and share it with you. Only Super Admin(s) will have access to update the code.
Note: Please remember the Approver Code as you will need it every time to approve/reject an order.
