What should I do if my iPhone or iPad is lost or stolen?
If you have the Find My iPhone app you can use it to remotely lock the device and disable the use of the Apple Pay function. Or you can log into iCloud.com and remove all cards from Apple Pay remotely. If you do not have the app you should contact us on 13 25 85 to request that your card be disable for use with Apple Pay.
