Which carriers matter, what buying a SIM involves, and when an eSIM is the smarter move.
Reliable mobile internet at better prices than most travel eSIMs, with polished iOS and Android apps and support for making and receiving phone calls.
One of the biggest travel eSIM brands, with a very large destination catalog.
Known for unlimited-data plans in many destinations, at a higher price per gigabyte.
Finland shut down 3G but kept 2G, the opposite of most of Europe, so bring a 4G or 5G handset. The cheap local MVNOs you see online (Moi, Globetel, Giga Mobiili, Oomi) all require a Finnish bank account and are closed to visitors, so stick to Elisa, Telia or DNA. Finland is in the EU, so roam-like-at-home applies, but the EU allowances on unlimited plans are capped.
Finland's largest operator, selling prepaid under the Saunalahti brand. Unlimited-data plans are the norm here.
Near-total 4G coverage nationwide. Oddly, Telia's own shops do not sell tourist prepaid: you buy Telia prepaid at convenience stores.
Good value with fast 5G, and coverage on par with the other two thanks to a network shared with Telia across the sparse north and east.
There is no clear legal requirement to register a prepaid SIM in Finland, and cards are sold freely in supermarkets and kiosks. Still, bring your passport: some stores register the SIM to your name, and a convenience-store purchase can involve self-registering by scanning your passport with your phone.
Guac eSIM covers Finland with data plans starting from $1.50 per GB and instant activation, so your phone is online the moment you land. Airalo and Holafly are popular alternatives.
