I'm from Belgium. I always bought FC with a prepaid card (in my case that is a wallie card). When I didn't have a Wallie card available at that time and I was too lazy to go to the store to get me one, I often used my mobile phone to get some cash.
This morning, I wanted to buy some cash (now credits ofcourse) with my mobile phone. I had to select a country from the drop down menu. Belgium isn't listed
I never, ever had any problems purchasing cash with my mobile phone before. And now, since they changed it, we, the people from Belgium can't buy credits with the mobile. THIS SUCKS BIG TIME.
