A Baltic trip often runs from Vilnius's baroque old town to Riga's Art Nouveau quarter and medieval Tallinn, then across the Gulf of Finland by ferry to Helsinki. All four countries are in the EU, so on land an EU SIM works in each as it does at home. The trap is on the water: some ships run their own mobile network, billed separately and not part of Roam Like at Home.
This guide to an eSIM for the Baltics and Helsinki covers what EU and non-EU visitors need, how to handle the ferry, and how the Scandinavia & Baltic and Europe plans compare.
Key facts for the Baltics and Helsinki
- EU roaming: Estonia, Latvia, Lithuania and Finland are all covered by Roam Like at Home
- One plan for the route: the Scandinavia & Baltic plan covers all four, and so does the Europe plan
- On the ferry: onboard ship networks are billed separately and are not part of Roam Like at Home
- Local networks: Telia, Tele2 and Elisa in Estonia; LMT, Tele2 and Bite in Latvia; Telia, Tele2 and Bite in Lithuania; DNA, Telia and Elisa in Finland (depending on the plan)
- Emergency numbers: 112 in all four countries
- Embassies: in Tallinn, Riga, Vilnius and Helsinki
Who needs an eSIM for the Baltics and Helsinki
With an EU SIM, all four countries count as home on land. A travel eSIM only helps if your tariff includes little data abroad.
With a SIM from outside the EU, the UK included, roaming is usually charged by the day unless your tariff includes these countries. One Scandinavia & Baltic or Europe plan on an eSIM covers all four, while your home SIM keeps your own number.
The Tallinn–Helsinki ferry
Near either coast, the phone uses Estonian or Finnish land networks, covered by EU roaming and by both zone plans. Out at sea, some ships run their own onboard network, which is not part of Roam Like at Home and is billed separately by your home operator.
On board, keep data roaming off on your home line, or choose an Estonian or Finnish network manually while one is in range. On a travel eSIM, a manually chosen land network keeps you online while its signal reaches.
Between the capitals and beyond
Travelling between Vilnius, Riga and Tallinn crosses two borders, and the phone moves to the next country's networks on the way. With an EU SIM or a zone plan that changes nothing; a country plan does not cover the next country, so choose that country's network manually near the border. Near any other border, choose the local network manually, whatever your plan.
Coverage is strong in all four capitals. It thins out on the boardwalk trails of Lahemaa and Soomaa national parks in Estonia and in the deeper parts of Latvia's Gauja valley, so download offline maps before you head out.
Which plan fits your trip
With an EU SIM, you may need nothing extra on land. From outside the EU, two Telcomia zone plans cover all four countries on one eSIM. The Scandinavia & Baltic plan covers eight destinations: the four, plus Sweden, Denmark, Norway and Iceland. The Europe plan covers 38, including the four, Sweden, Denmark and Norway, most other EU countries, the UK and Switzerland, but not Iceland.
Each country also has its own plan, for example for Estonia, which suits a stay in one country only.
Open the plan details before you buy: they show the duration, the data, whether you can share the connection with other devices, and the Activation line, which tells you what starts the plan's validity.
Before you leave
- Check your home tariff's data allowance in the EU, or whether a non-EU tariff includes these countries.
- Read the Activation line in the plan details, then install the eSIM at home on Wi-Fi.
- Set the eSIM as your mobile data line, with data roaming on for the eSIM and off for your home line.
- Before the ferry leaves port, check that data roaming is off on your home line; if you rely on your EU SIM for data, turn it back on ashore.
- Keep the eSIM installed until the trip is over: some eSIMs can be installed only once.
Consular protection: one number in four countries
- 112 reaches the emergency services in Estonia, Latvia, Lithuania and Finland; in Finland it also covers sea and mountain rescue.
- In Latvia you can also dial 110 for the police and 113 for an ambulance.
- Embassies are in Tallinn, Riga, Vilnius and Helsinki. The Telcomia app shows which mission is responsible for you, with address and phone.
- Emergency phrases in Estonian, Latvian, Lithuanian and Finnish are ready to show on screen in the app.
Questions travellers ask about the Baltics and Helsinki
Does EU roaming work in the Baltics?
Yes, for SIMs from EU countries: Estonia, Latvia and Lithuania are part of Roam Like at Home, and so is Finland. It does not cover onboard ferry networks.
Will my phone work on the Tallinn–Helsinki ferry?
Near either coast it uses Estonian or Finnish land networks. Out at sea, a ship's own network may take over, billed separately, so keep data roaming off on your home line on board.
Scandinavia & Baltic or Europe plan?
Both cover Estonia, Latvia, Lithuania and Finland, and both continue into Sweden, Denmark and Norway. Choose Scandinavia & Baltic if the trip continues to Iceland, and Europe if it continues to most other EU countries, the UK or Switzerland.
Which emergency number works in all four countries?
112, in Estonia, Latvia, Lithuania and Finland alike. Latvia also has 110 for the police and 113 for an ambulance.
The short version
From the EU, your tariff covers all four countries on land; from elsewhere, one Scandinavia & Baltic or Europe plan does. On the ferry, keep data roaming off on your home line, and save 112.

When should I activate my Estonia eSIM?
Each plan shows before you pay when it starts counting. Plans that start on connection start counting the first time they connect to a network in one of the countries they cover: install the eSIM before you leave, keep the line off until you arrive in Estonia, and you'll have data as soon as you land. Some also work in other countries (each plan lists which): if the line connects earlier, at home or on a layover, it starts counting there. Plans that start when you buy them are best bought on the day you'll start using them.
