Telia, Elisa and Tele2 cover cities and highways on 4G and 5G; forested park interiors and small western islands can thin out briefly. Tallinn Old Town stays well served. Check the network list above for Estonia before you fly; it shows what is available right now, including options such as Elisa, Tele2, Telia.
There is no complicated Estonia-only product to learn. NXTL is one global eSIM: the same profile you might use elsewhere works here on Elisa, Tele2, Telia when listed. Land, turn data on, and go — rates for Estonia are shown live on this page because they can change.
EU roaming applies for many visitors; others buy prepaid at the airport R-kiosk and operator shops with ID. Estonia is heavily digital, so mobile data replaces paper for many services. That still makes sense if you will live in Tallinn for months and need local calls. For a holiday or short work trip, most people only need data — and NXTL gives you that without the desk stop: install at home, keep your usual number for calls and bank texts, pay only for the gigabytes you use.
If Estonia is one stop on a longer route, NXTL is built for that. Use data around Tallinn and Tartu, then keep the same balance wherever NXTL has coverage next. You are not locked into a single-country tourist pack.
Tallinn–Helsinki ferries cross the Gulf of Finland where your phone may roam onto Finnish networks mid-route. NXTL is built for that kind of Estonia trip: data when you need it, without buying a new pack for every change of plan.
