I've bought tickets for Billie Eilish concert in Wien (6.6.2025). The mobile tickets were available a day before the event, I was informed on my e-mail. Everything was OK, the seats were as ordered, the tickets were legitimate. I'm from Slovenia - important: in order to transfer the tickets, you MUST have a ticketmaster account. You cannot create one with a phone number from Slovenia. I have a friend in Austria, who helped me (I've created a ticketmaster account using his telephone number - he told me the code, when he received it). Anyhow - the tickets from Stubhub were a bit pricey, but the show was sold out, so I've payed more and ENJOYED THE SHOW!
