Oslo eSIM

100 Norway plans · from $2.23

Oslo sits at the head of a fjord with forest at the end of the metro line, and it is the usual starting point for the Bergen railway and the fjord routes west. A travel eSIM covers the city and the whole country — worth having in Norway, where roaming from outside the EEA is expensive and the scenery is mostly in places you will want a map.

Landing at Gardermoen (OSL)

The Flytoget express reaches Oslo S in 20 minutes; the regular Vy trains take a few minutes longer for roughly half the price and leave from the same platforms. Knowing that before you buy is worth the eSIM on its own.

Which networks you'll be on in Oslo

Siima eSIMs for Norway ride Telenor and Telia. Norwegian coverage is unusually good for the terrain — Telenor reaches most of the fjord and Arctic regions, though the mountains are still the mountains.

Coverage around Oslo

T-bane and the city

Coverage across the metro network including the tunnel sections under the centre, and throughout Sentrum, Grünerløkka and Aker Brygge.

Fjord ferries and Bygdøy

The Oslofjord ferries and the museum peninsula at Bygdøy hold signal the whole way, including the short hops to the islands.

Nordmarka and Holmenkollen

The forest at the end of the T-bane is covered on the main tracks and around the ski jump. Deeper into Nordmarka it thins, as it does in most Norwegian forest.

The Bergen railway and the fjords

One of the great train journeys, and coverage follows it for much of the route with real gaps crossing the Hardangervidda plateau and in the long tunnels. Flåm and the fjord villages are covered.

How much data you need

A few days in Oslo is 2–3 GB. A fjord trip with constant navigation and ferry timetable checks is closer to 5 GB over a week.

Frequently asked questions

Is Norway covered by EU roaming rules?
Norway is in the EEA, so EU residents generally roam at home rates there. Travellers from outside the EEA — the US, UK, Canada, Australia — get no such protection and face standard international roaming charges, which is where a travel eSIM pays for itself.
Will my eSIM work in Lofoten and Tromsø?
Yes, on the same country plan. The Arctic towns, Lofoten's main road and the northern lights viewing spots near them are covered. Mountain hikes and the more remote islands lose signal.
How do I set up an eSIM before arriving in Oslo?
Install it at home while you still have Wi-Fi: open Settings → Cellular → Add eSIM and scan the QR code from your Siima confirmation email. Leave the line switched off until you land — the plan starts counting from first use in Norway, not from purchase.
How much data do I need for a trip to Oslo?
A few days in Oslo is 2–3 GB. A fjord trip with constant navigation and ferry timetable checks is closer to 5 GB over a week.
Is an eSIM cheaper than roaming in Oslo?
Almost always. Daily roaming passes from most home carriers run $10–15 per day, while Siima plans covering Oslo start from $2.23 for the whole trip. You also avoid per-megabyte charges if you exceed a roaming pass allowance.
