To change your phone number, you can easily open the KodyPay app and tap on the icon in the top left corner to go to your profile. Once you have done this, simply press "Edit Settings" and tap on your phone number. You are then able to type in a new number and confirm your password to authorise the change. You will then receive a text with a verification number to type in on the KodyPay app to ensure the phone number is yours. Then, continue using KodyPay as normal!
