Cheapest unlimited eSIM for Estonia? From €5.50 for 3 days (October 2026)

From €5.50 you can have an unlimited eSIM for Estonia for 3 days, without worrying about megabytes or unexpected charges on your bill. If your trip is longer, you’ll also find unlimited plans for 5 and 7 days at equally clear, fixed prices in euros.

Why choose an unlimited eSIM for Estonia?

Estonia is one of the most digitally advanced countries in Europe: free Wi-Fi throughout Tallinn, tram apps, museum audio guides online, and digital restaurant bookings. Having mobile data at all times isn’t a luxury — it’s practically essential to make the most of everything the country has to offer.

With an unlimited plan, you’ll never have to worry about “how many GB do I have left?” You can use Google Maps, upload photos, make video calls, or look up information about your next castle without watching the counter. And since the price is fixed in euros, you know exactly what you’re spending before you leave home.

What’s more, with a Roam2Go eSIM everything is digital: no physical SIM card, no queuing at an airport kiosk, no risk of losing your local SIM during your trip. Buy it, install the QR code, and you’re good to go. If you’d like to understand how it all works, have a look at our guide on how an eSIM works.

Roam2Go unlimited plans for Estonia: 3, 5 and 7 days

Here are the 3, 5 and 7-day unlimited plans for Estonia; you’ll find longer unlimited plans in the table below. Fixed price, no data limits, and instant activation:

• Unlimited 3 days: €5.50 — ideal for long weekends or a quick getaway to Tallinn.
• Unlimited 5 days: €7.95 — perfect for a short week exploring the coast, the islands, or the capital.
• Unlimited 7 days: €10.99 — the best option if you want to travel around the country at a relaxed pace, from Tallinn to Tartu or Lahemaa National Park.

If you expect to use data very heavily (streaming, long video calls, remote working), the unlimited plan is clearly the most convenient choice. If your usage is more moderate, a data plan per GB might suit you just as well at a better price — you’ll find those in the table below.

How to choose the right plan for your trip

Short trip (1–3 days): a weekend in Tallinn

If you’re spending a weekend in Tallinn sightseeing, the 3-day unlimited plan (€5.50) is the most practical choice. No worries about anything: Google Maps, cloud photos, Instagram stories… all without limits. If you know your usage will be very light, the 1 GB plan at €1.88 may be enough for messaging and basic maps — but for normal usage, the 3-day unlimited plan usually offers the best value for money.

Mid-length trip (4–7 days): discovering the country

If you’re planning to venture beyond Tallinn and explore Tartu, Pärnu, or Lahemaa National Park, the 5-day unlimited plan (€7.95) or the 7-day plan (€10.99) will serve you brilliantly. You’ll be able to look up routes, find local restaurants, and browse freely. If you’d rather pay per GB and you’re disciplined with your usage, the 10 GB or 15 GB 30-day plans also cover this type of trip very well.

Longer stays or remote working

For stays of three weeks or a month, or if you’re working remotely while travelling, the 20 GB or 30-day unlimited plan (€26.50) gives you the flexibility and data capacity you need without any billing surprises.

Activation in 5 minutes: how it works

Buying and activating the eSIM for Estonia is really straightforward. Once your purchase is complete in the Roam2Go shop, you’ll receive the QR code by email within minutes. Scan it from your phone’s settings (Settings → Mobile Data → Add Plan on iPhone; or Settings → Connections → SIM Manager on most Android devices) and it’s installed.

The plan activates automatically when you arrive in Estonia and your phone connects to the local network. No further action needed. You can install it days before you travel so it’s all ready to go — the countdown doesn’t start until you connect at your destination.

One important thing: check that your phone is eSIM-compatible and that it isn’t carrier-locked before purchasing. Most current smartphones (iPhone XR and later, Samsung Galaxy S20 and later, Pixel 3 and later…) are compatible, but it’s always worth double-checking.
