Travel eSIM Ireland

It will! Since Northern Ireland is part of the UK we have added the UK to our Ireland eSIM by default so it will work in ALL of Ireland. It also works in the UK if you happen to be visiting there to make things a little easier for you.

No, our Ireland eSIMs only deliver mobile data. For voice or SMS, you’ll need to use an app that works over data - WhatsApp, Messenger, or other similar internet calling platforms.

Yes! Your Ireland eSIM can be installed as early as 30 days before you travel. It won’t start until you touch down in Ireland.

Installing beforehand means no setup stress on arrival, and it won’t use any data or days until you land.

If you get an activation warning on iPhone when installing before arriving, that’s normal - check our eSIM Troubleshooting Guide for details.

No, our Ireland travel eSIMs do not include any phone number - they strictly provide internet data. For calls, use data - driven apps such as WhatsApp, Messenger, or Facetime.

Your eSIM will activate automatically when you land in Ireland. However, we recommend installing the Ireland Travel eSIM beforehand (activation happens on arrival).

Simply scan the QR code provided or install the eSIM via the ZenSim app while on WiFi. Once you touch down in Ireland, the eSIM will go live.

Trouble activating? See our eSIM Troubleshooting Guide or contact us for help ☺️

Your Ireland eSIM will start working the moment you land in Ireland-it auto-activates if installed prior to departure.

If you install it after arrival, it will connect immediately.

If you want to avoid roaming headaches in Ireland, a travel eSIM is the smarter pick:

Big Savings: Our local Ireland eSIM data plans are priced for residents, not tourists who pay premium roaming costs.

Easy Plan Changes: Upgrade or downgrade your data allowance on the fly - no need for a new SIM.

Full Transparency: See your data usage in - app so you won’t run out unexpectedly or incur extra charges.

No - the plan’s data and days only start when you arrive in Ireland. Installation beforehand simply sets it up for activation on landing.

We recommend installing before departure since you will need WiFi to complete the installation process and this way you will be connected as soon as you land.

Yes! Our eSIMs cover more than 200 countries, including Ireland. We even provide regional eSIMs that span multiple countries in one package - head over to our Travel eSIMs page to learn more.

Signal & Connectivity: If you’re stuck without data, follow our detailed troubleshooting guide. If issues persist, contact support and we’ll fix it promptly.

Install Assistance: For help installing, consult our installation walkthrough. Still need help? Reach out and we’ll guide you step by step.

Yes it can. Nearly all ZenSim eSIMs support top ups inside the app. You can boost your data, add extra days, or attach a new country to the same eSIM from the Zen Garden in only a few steps.

Just log into the app, open the Zen Garden, and you’ll find the top up control ready to use.

Top up choices: The Ireland top ups match the plans on our website, just with an extra 10% off.

If you're travelling longer than 30 days: You can purchase multiple top ups in advance. They only activate once the current plan finishes, so nothing overwrites your existing eSIM.

If your trip includes several destinations: Many of our eSIMs support multi country top ups. For example, you can add Dubai to a Europe eSIM and it will activate the moment you arrive without reinstalling anything.

After activation in Ireland, your eSIM won’t usually work elsewhere. Each country typically needs its own eSIM unless you're using a regional one.

To make travel easier, try one of our regional Travel eSIMs - they work across entire continents.

Yep, you can, can you should! For every friend or family member you refer to purchase a Ireland eSIM, you will earn a A$5 voucher to use on your next purchase AND they will save A$5 on their purchase.

All you have to do is share your unique referral URL with them, which you can access after purchase, and if they click it and purchase the savings are automatic.

You can monitor your referrals and find your personal referral URL directly in the ZenSim app. Read our terms for full details.

Only on unlimited plans, and only past 3GB in a single day - which is a generous amount, considering most travellers use less than 1GB daily.

If you do go past 3GB, your speed will be limited to 1Mbps until midnight, when it resets and you're back to full speed again.

Fixed-data plans (10GB, 20GB, etc.) don't have any daily throttling - you're free to use your data at whatever pace suits you until the plan's used up. We'll flag it before you run out, and topping up takes just a couple of taps in the ZenSim app.

It won't activate the moment you buy it - your Ireland eSIM won't touch your data or days until you actually arrive, so there's no downside to installing it in advance.

As long as it's installed beforehand, it'll activate itself the second you touch down, and that's the moment your plan officially begins.

As for running out - your eSIM expires once your data or days are gone, whichever comes first (just the days, if you're on unlimited). Buy a 30-day plan and it'll run out 30 days after arrival in Ireland, not 30 days after purchase.

Quickest way to check is through our eSIM compatibility checker - it'll let you know in seconds if your phone plays nicely with our Ireland eSIM and the networks it runs on.

If anything's unclear or you'd rather double check with a human, reach out to us anytime. And if your phone ends up not being compatible, you're covered by our refund policy - full refund, no hassle - so it's worth just giving it a go.

We've got a 100% money back guarantee for exactly this kind of situation.

That covers trip cancellations, phones that turn out not to be eSIM-compatible, or just a change of plans that means you no longer need it.

Our full refund policy spells it all out, but the short version is: unable to install or use the eSIM means a full refund, every time.
