To activate an Apple iTunes Card, you must have the iTunes app installed (if you don’t have an account, you can create one by following this link) and then follow these steps:

1. Log in to your iTunes account.
2. Go to the “Store” section of the app, where you will find a “Redeem” button. Click on it.
   
3. Once you are on the redeem section, enter your gift card code in the designated area.
   

Please note that your gift card must be valid in the region/country you are located in. We recommend checking the gift card restrictions on the product page before purchasing.
