You should still be able to call #227 to make a payment on a suspended line.

Hi @ilyuxa_th, try to check if your account is eligible for a Self Serve payment arrangement, here is a guide https://www.koodomobile.com/en/help/past-due-bill

That way you will have time to register your card and make a payment before your account is suspended. 

If your account is not eligible, you can contact our Payment team at #227 as well to check if they can assist with an arrangement or with registering your international card.
