You must first log out of the FIFA Intercontinental Cup 2024™ app on your old phone. To do this, tap the main burger menu icon in the top left corner, then select “Sign Out” and confirm the log-out process. Once you have done that, install the app on your new smartphone and log in with the same email address and password associated with your purchase.
If you no longer have access to the device where you had previously downloaded the app, please contact FIFA Customer Support via the contact form for further assistance.
