Before you set off for Czechia, make sure you have everything. Here is the essential checklist.

## Checklist

- Valid passport/ID (Schengen for most of the EU)
- An eSIM-compatible phone + MerrSIM eSIM
- A bank card (little cash needed)
- Flight/hotel bookings on your phone
- Travel insurance (optional but advised)

## Get online at the airport

Install a MerrSIM eSIM for Czechia (from €1.99, 10 GB €9.99) before departure and you’re online the moment you land at Václav Havel Airport Prague — no WiFi hunt, no roaming.

## 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 “Czechia” 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.

## 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 Czechia, so you land and are online immediately — no time wasted at the airport and no risk of surprise roaming bills.

## 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 Czechia will be trouble-free.

## 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 Czechia.

## How much data you really need

For normal use — maps, messaging, social media and the odd video — budget about 300–700 MB a day. A light traveller is fine with 3–5 GB for a week, while anyone doing video calls, streaming or laptop hotspot will want 10–20 GB. In Czechia, download offline maps and use hotel WiFi for big downloads; that way a 10 GB plan comfortably lasts two weeks. If you run out, you buy a new plan in the app with no waiting.

## FAQ

### How do I get online as soon as I arrive in Czechia?
Activate a MerrSIM eSIM for Czechia (from €1.99, 10 GB €9.99) by QR before departure; you connect automatically at the airport.
