You are trying to say that you can't add American Express to Samsung Wallet?
What device do you have?
Samsung Pay allows you to make quick and easy payments from your eligible Samsung devices in-store (at virtually any terminal where contactless Cards are accepted). It’s simple to add your Card to your compatible Samsung device:
Open the Samsung Pay app on your device and tap "Add" sign. (If you do not have the app, you can download it from the Google Play Store.)
Add your Card manually by entering your Card information or scan a picture of your Card.
Enter the 4 digit number on the front of your Card and accept the American Express Terms of Use for Samsung Pay. (You will also need to accept Samsung’s own Terms & Conditions which you can find here).
To add an eligible American Express Card on Samsung Gear, you must first pair it with a supported Samsung phone using the phone's Samsung Gear app. Once paired, open the Samsung Gear app, go to "Samsung Pay" and tap on "Add Card."
