Wi-Fi on SAS long haul A330? What to expect

Flying VIE-CPH-JFK tomorrow and I’m curious about internet on the A330-300. I don’t need it on the short hop, but on the long haul I’d really like to stay connected.

Does SAS have Wi-Fi on those A330s? If so, how much does it usually cost and where can you buy it (before the flight or onboard)?

Any recent experiences or tips would be much appreciated!
