## 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.

## 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.

## 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 Ireland, that means peace of mind and often a real saving compared with leaving roaming switched on unchecked.

## 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 Ireland.

## FAQ

### How do I get online as soon as I arrive in Ireland?
