Ahh! Thank you for explaining, stavro333 ... if I understand correctly, seems you want to pay off the amount you still owe to Apple in instalments using the international cards you have in Europe. (The cards, (eg: if added to wallet, or used with Apple Pay) should be ok.) If needed: Apple Pay participating banks in Africa, Europe, and the Middle East - Apple Support
Installment plans are generally set up at the checkout when making a purchase from Apple. Sorry I don't know whether or not an instalment plan can be set up in order to pay off a remaining balance. (As Apple users, like yourself, in the community here, we can not speak for Apple, and have no access to your accounts or details.)
You may want to speak with someone at Apple Support in the country you are in:
In the linked "contact" article below, you can scroll down to: "Connect with live support" and choose the country you are in, to be shown the correct phone number: How to: Contact Apple Support - Apple Support
Else, if need be, and your Apple card has enough credit, you could likely just pay however much you want when convenient, and pay the interest charged on what remains.
See: How to avoid or lower Apple Card interest charges - Apple Support
Eg: says:
"How interest is estimated "
If you're unable to pay your monthly balance by the statement due date, Apple Card makes it easy to see how much you need to pay to lower your interest charges.1 Estimated interest charges are automatically calculated and presented to you any time that you make a one-time payment in the Wallet app."
and
"Apple Card Monthly Installments (ACMI) is a 0% APR payment option that is only available if you select it at checkout in the U.S. for eligible products purchased at Apple Store locations, apple.com, the Apple Store app, or by calling 1-800-MY-APPLE, and is subject to credit approval and credit limit.
See support.apple.com/102730 for more information about eligible products. Existing customers: See your Customer Agreement for your variable APR."
There is a great deal more info. in that "How to avoid ..." article.
