What if I'm going to a country where you don't offer the currency? What rate will I get?

You should load GBP onto your card if you need to spend in a currency different from the 15 we offer. You’ll automatically get the standard Mastercard settlement rate minus 2.49%, at the time of your transaction. You do not need to do anything else, the conversion will take place when you make a transaction.

If you load any currency other than GBP (USD for example), your transactions will automatically be converted back into GBP before being converted again into the local currency, which is not as good value as one direct conversion from GBP.
