What about the Switzerland? Can I order your prepay card if I'm a Swiss citizen?
Germany, Austria, Belgium, Bosnia Herzegovina, Bulgaria, Cyprus, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Greece, Hungary, Ireland, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Sweden, Switzerland, Slovakia, Slovenia, Spain, and United Kingdom.
So yes, Switzerland is in the list.
There are 33 counties in this list an EU consists of 28 of them. So it's not completely right to say epay cards are for EU citizens only.
