Stay Connected in Tallinn
Network coverage, costs, and options
Connectivity Overview
Tallinn's actually got pretty solid connectivity infrastructure, which makes sense given Estonia's reputation as one of Europe's most digitally advanced countries. You'll find 4G coverage throughout the city and surrounding areas, with 5G gradually rolling out in central locations. The three main mobile operators—Telia, Elisa, and Tele2—all offer decent coverage and speeds that'll handle video calls, streaming, and whatever work you need to do. Free WiFi is everywhere in Tallinn's Old Town, cafes, and public spaces, though you'll want to be careful about security on open networks. For most travelers, staying connected here is straightforward—the question is really just whether you want the convenience of an eSIM or prefer hunting down a local SIM card.
Get Connected Before You Land
We recommend Airalo for peace of mind. Buy your eSIM now and activate it when you arrive—no hunting for SIM card shops, no language barriers, no connection problems. Just turn it on and you're immediately connected in Tallinn.
Network Coverage & Speed
Estonia's mobile network is genuinely impressive for a country its size. All three major carriers—Telia, Elisa, and Tele2—offer reliable 4G coverage throughout Tallinn and most populated areas. Speeds typically range from 20-50 Mbps for downloads, which is more than enough for streaming, video calls, and remote work. 5G is available in central Tallinn if you've got a compatible device, though honestly, the 4G speeds are usually sufficient for travel needs.
Coverage extends well beyond the capital too—you'll get solid signal along the highways and in most towns. It does get a bit patchy in rural areas and forests (Estonia has a lot of forests), but anywhere tourists typically go, you're covered. The network quality is stable enough that many digital nomads base themselves here without issues. Worth noting that Estonia's small size means you're never too far from a cell tower, so dropped calls are pretty rare compared to larger countries with more remote areas.
How to Stay Connected
eSIM
eSIMs have become increasingly popular for Tallinn, and honestly, they make a lot of sense here. You can set one up before you even leave home through providers like Airalo, and you'll have data the moment you land—no hunting for SIM card shops or dealing with language barriers. Prices are reasonable, typically around €5-15 for a week's worth of data, depending on how much you need.
The main advantage is convenience and time savings. You avoid the airport kiosk queues and can compare plans calmly from your couch. The downside? Local SIMs are usually a bit cheaper if you're staying longer or need lots of data. But for most short trips (under two weeks), the price difference is maybe €5-10, and many travelers find the hassle-free setup worth that premium. Just make sure your phone actually supports eSIM before committing to this route.
Local SIM Card
If you'd rather go the traditional route, getting a local SIM in Tallinn is straightforward enough. You'll find the main carriers—Telia, Elisa, and Tele2—at the airport, though be prepared for potential queues and slightly inflated airport pricing. Better deals are usually at their shops in the city center or at Rimi and Selver supermarkets, where you can grab prepaid SIMs for around €5-10 with several GB of data included.
You'll need your passport for registration, and most staff speak English well. Activation is usually immediate, though occasionally it takes 30 minutes or so. Tourist-specific prepaid plans typically offer 5-20GB for €10-20, which should last most travelers a week or two. The main hassle is just finding the time to visit a shop and dealing with the setup process—not difficult, but it does eat into your first day. For longer stays beyond a month, local SIMs definitely make financial sense as you can top up cheaply.
Comparison
Here's the honest breakdown: Local SIMs are cheapest (€10-15 for generous data), but require time and effort to obtain. eSIMs cost slightly more (€5-20 depending on duration) but work immediately and save you the airport hassle. Roaming from your home carrier varies wildly—EU visitors often have free roaming, while travelers from elsewhere might face eye-watering charges. For short trips, eSIM convenience usually wins. For month-long stays, local SIM economics make sense. EU travelers with inclusive roaming might not need either, though having a backup option is smart.
Staying Safe on Public WiFi
Tallinn's abundant free WiFi is convenient, but it comes with the usual security risks that matter more when you're traveling. Hotel networks, airport hotspots, and cafe WiFi are generally unencrypted or use shared passwords, meaning others on the network could potentially intercept your data. That's particularly concerning when you're accessing banking apps, booking accommodations, or dealing with passport and travel documents—exactly the stuff you do more while traveling.
A VPN encrypts your connection and makes your online activity unreadable to others on the network. It's not about paranoia—it's just sensible protection when you're managing sensitive information on unfamiliar networks. NordVPN works well for this, creating a secure tunnel for your data even on sketchy public WiFi. Worth setting up before you travel, honestly, since you'll likely be hopping between various networks throughout your trip.
Protect Your Data with a VPN
When using hotel WiFi, airport networks, or cafe hotspots in Tallinn, your personal data and banking information can be vulnerable. A VPN encrypts your connection, keeping your passwords, credit cards, and private communications safe from hackers on the same network.
Our Recommendations
First-time visitors: Go with an eSIM from Airalo. You'll land with working data immediately, can navigate to your accommodation without stress, and avoid the confusion of finding a SIM shop when you're jet-lagged and disoriented. The convenience factor is huge for your first day in a new city.
Budget travelers: Local SIM is technically cheaper by maybe €5-10, so if you're on an extremely tight budget, that matters. That said, the time you'll spend finding a shop and setting it up has value too—consider whether saving a few euros is worth the hassle and potential first-day connectivity gaps.
Long-term stays (1+ months): Definitely get a local SIM. The cost savings add up over time, and you'll want the flexibility of easy top-ups and potentially better long-term rates. Worth the initial setup effort.
Business travelers: eSIM is really your only sensible option. Your time is valuable, you need immediate connectivity for work, and the last thing you want is hunting for a SIM shop between meetings. Set it up before departure and forget about it.

Purchase your eSIM before your trip and activate it upon arrival—you'll have instant connectivity without the hassle of finding a local shop, dealing with language barriers, or risking being offline when you first arrive.
