The next city in the trip is Stockholm, in Sweden. Here at the airport there is a hotspot with pre-paid credentials (network name is LFVPUBLIC). The minutes that you buy remain valid for up to 30 days from first use, so frequent travelers through Arlanda Airport can buy time through a scratch card, add the credentials to their Devicescape account and get online automatically while sipping coffee waiting for their flight.
I did also find a Telia Homerun location in the Sky City area (where the Roberts Coffee stand in the photo is located), and you can just about get a connection to the Radisson hotel’s Netpoint service too from the same area.
