A day cycling Copenhagen, then a train ride across the bridge to Sweden
Copenhagen looks best from a bike saddle, and just across the Öresund Bridge, a thirty-five-minute train ride away, is another country entirely. Let's walk through a typical visitor's day: renting a bike in the morning, navigating the waterside bike lanes, and a day trip to Malmö that means remembering a second eSIM plan.
Copenhagen by bike: a day's route with no paper map
In Copenhagen a bike isn't a tourist gimmick, it's the main way to get around: the city is lined with dedicated bike lanes, and rental bikes like Donkey Republic and Bycyklen unlock through an app using your location. Without data the bike simply won't unlock, and a paper map won't help you hold the right lane in a stream of locals commuting to work.
A route through Christianshavn, Nyhavn and Kastellet park is easiest to build right in a navigation app: distances are short, but streets often don't run the way you'd expect, and one-way bike lanes need attention to signage.
The Öresund Bridge: how one train ride changes your plan
The Öresund Bridge and tunnel connect Copenhagen to Malmö in Sweden, and the Öresundståg train covers it in about half an hour. It's a popular day trip, but it's worth remembering: a local eSIM plan for Denmark only covers Danish territory, and once the train crosses into Sweden you'll need either a separate Sweden plan or a regional Europe plan for data.
Before a trip like this, check the country list on the plan page in advance and add a second profile or regional package if needed, so you're not without maps the moment you reach Malmö.
Check the current border-crossing rules before you go — spot document checks sometimes happen on the bridge route.
Payments and tickets in Danish apps
Copenhagen's public transport — metro, buses, S-tog trains — is easiest to plan in the Rejseplanen app, and a metro ticket can be bought right on your phone without hunting for a machine. Contactless card payment on transport and in shops is standard, while cash is increasingly rare.
Food delivery and taxi apps in Copenhagen work the same way as in other major European cities: all they need is data and a linked card, no Danish phone number required.
Odense, Aarhus and the islands in between
If the route continues beyond the capital — to Aarhus, the country's second city, or to Odense, the birthplace of Hans Christian Andersen — distances in Denmark are short, and coverage between cities is stable almost everywhere, including bridge crossings between islands. A day trip around the country with navigation and social media usually needs a few gigabytes, and if the route stretches over several days with heavy navigation and photos, it's worth taking a plan with some headroom.
Checklist for a bike day plus a cross-border trip
A few things worth sorting out in advance so the day goes smoothly:
- install the Denmark eSIM profile at home by QR code or the Quick install button
- download the bike rental apps and Rejseplanen while still on Wi-Fi
- check the country list on a regional plan if you're planning a trip to Malmö
- turn on data roaming for the eSIM only after landing in Denmark
- keep your home SIM in the phone for bank SMS
