Buying from Play store using a credit card with foreign billing address Is it possible to use a credit card with a foreign billing address to buy items from a local Play store?
I have a Visa credit card from a German bank with a billing address in Germany registered in my Google Wallet. I have successfully used my Wallet to pay for online purchases from several online service providers in different foreign currencies so I am sure the credit card is correctly registered in my Wallet account. However, while physically located in the UK, I cannot complete any purchase from the UK Play store. At the point when I need to select my preferred payment method from my Wallet account, it shows my registered credit card greyed out with the text "Unsupported Payment method" next to it.
As far as I know Google doesn't allow the use of International cards (at the moment).

I also heard from some other people (and t0mm13b acknowledges it too apparently) that the Play Store looks at your current SIM card to know your home country. So maybe if you could get your hands on a German SIM card (maybe an old one that doesn't really work anymore), you can still pay for applications.

Or you can have a look for some cheap credit card in the UK.
