Any Plan to add Pakistan in to Supported list ?
No such plans.
Except of Pakistan which other countries are excluded from your service?
It'll be easier if you log into your account or create one and see the list of countries there. We offer our services to most countries of the world with the exception of Iraq, Iran, Libya, Pakistan, Ivory Coast and a few others. Cards are not issued to India and USA, among others. You can ask me here or in the tickets about any particular country that you are interested about.
Well, if my country is allowed, I order the card and I travel to USA, will I be able to use my card there as USA is excluded from your service area?
