Why do UK mobile providers require a UK credit card?
It's not just the UK. Canadian mobile operators won't take non-Canadian credit cards either. Foreign credit cards are not accepted by US mobile operators either though if you have a foreign credit card you can still use PIN vendors like callingmart.com .
