## Why travellers choose MerrSIM

MerrSIM builds local plans for dozens of destinations, at a fixed price in euros — no dollar exchange rate and no surprises. Every plan includes hotspot, instant QR activation and no document registration. The app and support are in Albanian, which makes it easy for the diaspora and travellers from the region. For Estonia, that means a simple experience: buy it, scan it, and you are ready before you board the plane.

## 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.

## Does your phone support eSIM?

Before you buy, check two things. First, the phone must be eSIM-compatible: iPhone XR/XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and many recent Motorola, Huawei and Oppo models. Second, it must be carrier-unlocked. You can verify by dialling *#06# — if an EID number appears, your phone supports eSIM. This saves you any surprises when you arrive in Estonia.

## 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.
