# How to activate an eSIM in Estonia (step by step)

> How to activate a Estonia eSIM: install the QR before departure, turn on Data Roaming, connect automatically.

Activating a Estonia eSIM takes a few minutes. Do it before departure so you connect on arrival.

## Before you leave

- Make sure your phone is eSIM-compatible and unlocked.
- Buy the Estonia plan at MerrSIM and get the QR code by email.
- Connect to WiFi and scan it: Settings → Mobile → Add eSIM.
- Label the eSIM “Estonia”.

## When you arrive in Estonia

- Set the eSIM as your data line and turn on Data Roaming for it.
- Keep your main number for calls/SMS.
- You connect automatically to the local network (Telia, Elisa dhe Tele2).

Estonia has great public WiFi, but an eSIM keeps you connected even on the train to Tartu.

## Activation in a few minutes

Do the install before departure, while on WiFi. Open your phone settings, choose to add an eSIM and scan the QR code you received by email. Label the profile “Estonia” so it is easy to spot. When you land, set the eSIM as your data line and switch on data roaming for it — that is normal for travel eSIMs and adds no fees, because the plan is prepaid. Within seconds you are online, with no need to hunt for public WiFi.

## Tips to save data

A few small habits make your gigabytes last in Estonia. Download Google Maps offline before you head out, set video quality to “Auto” or 480p, and turn off background app refresh. Use hotel WiFi for big updates and high-resolution photo uploads. With these steps, even a modest plan covers the whole trip, and your hotspot stays free for the moments you really need it.

## No registration, no shop queue

Many EU countries require identity verification for local SIM cards, which means a queue, a shop and sometimes even a local address. A travel eSIM skips all of that: it is sold as an international data service, with no passport and no contract. You have it ready before you set off for Estonia, so you land and are online immediately — no time wasted at the airport and no risk of surprise roaming bills.

## eSIM versus roaming

Roaming with your home carrier can be expensive outside bundles — sometimes several euros per gigabyte, with bills that land after the trip. A local eSIM turns that into a fixed price you know up front: you pay in advance, you know exactly how many GB you have, and there are no hidden fees. For a trip to Estonia, that means peace of mind and often a real saving compared with leaving roaming switched on unchecked.

## Common mistakes to avoid

Three mistakes often spoil the start of a trip. First: buying the eSIM at the last minute at the airport, when you have no WiFi to install it — do it at home. Second: forgetting to switch on data roaming for the eSIM line, which makes it look like it is not working. Third: leaving mobile data on your home SIM, which racks up roaming charges. Check these three and your connection in Estonia will be trouble-free.
