If you are going to buy tickets for an event outside Sweden via Ticketmaster, you must create a separate user account on Ticketmaster's website for the country in which the event is taking place.

For instance, to buy tickets for a concert in Norway, you must create an account at Ticketmaster.no
You may create an account using the same login details (email address + password) as you have for your Swedish Ticketmaster account, but you will need a separate account for each country in which you wish to purchase tickets.

Please note that tickets purchased via Ticketmaster abroad will not appear on your Swedish Ticketmaster user account after purchase.

Below are the countries that you cannot log in via the Swedish Ticketmaster app, they have their own Ticketmaster apps:

Belgium
Czech Republic
Denmark
Germany
Spain
Netherlands
Norway
Austria
Poland
South Africa
Finland
Switzerland
United Arab Emirates
