If you have an american or english (or every other country where dragonborn is available) psn account you'll be able to download with that.

The only problem is that the playstation network cards do only work in the country where you bought it. That means that a swiss psn card will only charge a swiss psn account.

To buy it in another store you either need a credit card or have to buy a english/american/whatever psn card online.
