Mobile Phone Payment problem

[Kryst]

Hello.Today I found out that Amnesia can be bought with the mobile phone and I though this is a great idea since I don't have a credit card.So I went on the Mobile phone payment store page but when it says to select my country I can't as my country(Romania)doesn't appear on the list.So what should I do in this situation?Can I buy Amnesia by selecting the nearest country to me or the only solution is to buy it with a credit card?I'd appreciate any help I can get.Thank you.
