Before you set off for Ireland, 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 Ireland (from €1.49, 10 GB €8.99) before departure and you’re online the moment you land at Dublin Airport — 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 “Ireland” 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.

## How an eSIM works

An eSIM is a digital SIM built into your phone: there is no physical card to insert. You buy it online, get a QR code by email and scan it in your settings. Once installed, the profile lives on your phone and activates when you reach Ireland, connecting automatically to a local partner network. You can keep your main SIM at the same time, so your number still gets calls and texts while the eSIM handles data.

## 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 Ireland will be trouble-free.

## Tips to save data

A few small habits make your gigabytes last in Ireland. 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 Ireland, so you land and are online immediately — no time wasted at the airport and no risk of surprise roaming bills.

## FAQ
