eSIMatrix does not provide an unlimited‑data eSIM for Finland. All available plans have a fixed data cap, such as 20GB for 30 days priced at $17.00 USD, 10GB for 30 days priced at $9.00 USD, and 5GB for 30 days priced at $5.00 USD.
Because the plans have a set data allowance, choosing a fixed‑data option can be more cost effective unless a traveler is an extremely heavy data user. The 20GB plan, for example, offers the largest data bundle among the options and may suit those who need substantial internet usage while traveling in Finland.
