An unlimited data eSIM is the easy choice for a trip to Finland when you stream, video-call home or work from your phone and don't want to count gigabytes. But 'unlimited' means different things. Most providers give you a set amount of full-speed data each day and slow you down after it; only one of the five plans compared here has no daily allowance at all. So we compare the plans by how much full-speed data you get each day, not by the word on the box.

Read each row as 'the cheapest way to get at least this much full-speed data a day'. A provider whose plan gives more than the row asks for still counts, at its own price, with its real allowance in brackets; a dash means the provider has no plan that gives that much.

ONE eSIM's daily plans cost the same each day, so 15 days of the 1 GB a day plan is $22.35. The others sell set lengths with their own price for each; Nomad has no 15-day unlimited plan for Finland.
What 'unlimited' means with each provider
- ONE eSIM: daily unlimited plans from 1 GB to 10 GB a day at full speed, then 500 Kbps to 1 Mbps until the next day (each plan shows its speed before you buy). You choose 1 to 30 days at checkout: one eSIM, one purchase and one price for all the days (the daily price times the days). The 1 GB a day plan slows to 512 Kbps.
- Airalo: 3 GB a day at full speed, then 1 Mbps for the rest of the day, under Airalo's fair use policy; where a package has a different limit, Airalo shows it before you buy.
- Saily: 5 GB a day without a speed limit, then unlimited data at up to 1 Mbps.
- Nomad: 2 GB a day at 4G/5G, then 1 Mbps.
- Holafly: no daily allowance. Holafly's terms say a local operator's fair use policy may still slow very heavy use, for no more than a day at a time.

How we check prices
We read each provider's public Finland page on 27 October 2026 and took its unlimited plans for 7 and 15 days, in US dollars before any coupon or sale credit, with the full-speed data a day the provider states. ONE eSIM prices are our live list prices on the same day, multiplied by the number of days: one purchase and one price for all the days. Prices and allowances move, so we re-check every month and keep the date on the page. If a number is out of date, write to support@oneesim.app and we will correct it.
