Mariehamn eSIM
61 Åland Islands plans · from $2.45
Mariehamn is the capital of Åland, an autonomous, Swedish-speaking archipelago of some 6,700 islands sitting between Finland and Sweden. Åland is Finnish territory served by Finnish networks — it carries its own ISO code, which is why it appears separately here, but a Finland plan generally covers it.
Landing at Mariehamn Airport (MHQ)
The airport handles limited regional flights. Most visitors arrive by ferry — five to six hours from Stockholm or Turku, and the big Baltic ferries call here en route between the two.

How “Unlimited” works: Never cut off — each plan gives a set amount of full-speed data, then a slower speed. The exact allowance and speed are shown on every plan.Read more
Unlimited plans never run out and your eSIM is never disconnected, but every one has a fair-use limit: a set amount of full-speed data, after which the speed is reduced. The amounts differ between plans — most give a daily full-speed allowance that refills every 24 hours from when you first activate the eSIM, while Premium plans give a larger allowance for the whole plan instead. Each plan states its own allowance and the speed after it before you buy. At the reduced speed, messaging, maps, email and light browsing still work; video streaming and video calls may not. If you want every gigabyte at full speed, choose a fixed-GB plan.
Which networks you'll be on in Mariehamn
Siima eSIMs covering Åland ride Ålcom and the Finnish operators. The main islands are well covered; the outer archipelago is thinner.
Coverage around Mariehamn
Mariehamn and the main island
Good coverage across the town, the maritime quarter and the cycling routes on Fasta Åland.
The archipelago ferries
The inter-island ferries — free for foot passengers on many routes — hold signal near the larger islands and drop in the open channels.
The Baltic crossing
The long ferry legs to Stockholm and Turku pass through stretches with no coverage, and the Swedish half of the route is a different country entirely.
Bomarsund and the outer islands
The historic sites and the eastern islands have coverage in the villages, thinning across the smaller skerries.
How much data you need
A few days on Åland is under 1 GB. It is a cycling-and-ferry destination and there is not much to be online for.
