Unlimited Ireland eSIM

An eSIM is a digital SIM that’s already built into your device, so there’s no physical SIM card needed.

Just check your device is compatible, choose a plan, and install it instantly. Once you arrive at your destination, your eSIM connects to a local network so you can get online straight away – no SIM swapping or hunting for Wi-Fi.

We recommend installing your eSIM before you travel while connected to Wi-Fi.

It won’t activate until you arrive and connect to a local network. Once you land, simply make sure the eSIM is switched on in your device settings and you’re good to go.

No. Everything stays the same – your home SIM, contacts, and apps are unaffected.

First, restart your phone – most issues are solved immediately this way.

If needed, follow the simple troubleshooting steps in our Help Centre or contact our 24/7 support team.

Not at all! Most customers are set up in just a few minutes. Step-by-step instructions are provided in your email and the Simify app.

Plus, with our Money Back Guarantee, you’re covered with a full refund if there’s an issue we can’t resolve.

Why choose unlimited?
Unlimited plans are our most popular option because you don’t have to track data usage or worry about running out. Use maps, messages, bookings, and apps freely throughout your trip.

Prefer a fixed data plan?
Fixed plans are a great choice if you know roughly how much data you’ll use and mainly need connectivity for essentials like maps, messaging, and browsing.

It then comes down to where you’re travelling:

Travelling to one destination?
Our country plans are ideal for staying connected in a single destination.

Visiting multiple destinations in the same region?
A regional plan lets you stay connected as you move between nearby countries without switching eSIMs.

Travelling across different regions or with multiple stopovers?
Our Global plan offers extra peace of mind, keeping you connected across multiple regions and even during layovers.

4G and 5G in most cities and towns; speeds may be slower in remote areas.

Yes! You can send an eSIM to a friend via email through the Simify app under My eSIMs. We also offer discounts when purchasing more than one eSIMs.

Travel eSIMs are perfect for anyone who wants reliable internet while overseas – from holidaymakers and business travellers to digital nomads and frequent flyers.

They help you avoid roaming charges, skip local SIM shops, and stay connected on trusted local networks wherever you go.

eSIMs are simpler, more flexible, and often more affordable.

You can keep your home SIM in place, avoid expensive roaming fees, and get online as soon as you land. That means easy navigation, instant messaging, bookings on the go, and staying connected without hassle.

No worries! Under our 100% Money Back Guarantee, you can request a refund if your trip is cancelled or delayed.

Your eSIM includes unlimited data for the full duration of your plan. In some cases, local network providers manage traffic during very high usage periods – if this happens, speeds may be temporarily reduced for a short time (typically up to 24 hours) before returning to normal on their own.

This is uncommon but if you're ever in need of it being refreshed, our customer service team can help reset things for you – just reach out and we'll sort it out quickly.

Yes. Most devices store multiple eSIMs, though only one can be active for data at a time. Switching is simple via phone settings.

Your plan starts when the eSIM first connects to a local network at your destination. From that moment, your selected number of days begins counting down.

Check your mobile settings – the eSIM should appear. When you arrive, enable it as your primary data plan, turn on Data Roaming, and restart your device if needed. Support is available anytime if you get stuck!

Most devices are unlocked. If unsure, test with another SIM or contact your carrier. Phones on a plan may require unlocking first.

Our eSIMs focus on data, which means you can still call and message using apps like WhatsApp, FaceTime, iMessage, Viber, and more! all through your data connection.

If you plan to use traditional calls or texts, you can keep your home SIM switched on alongside the eSIM. In most cases this works automatically, but availability depends on your mobile plan. Your carrier can confirm this for you, and roaming charges may apply while you’re overseas.

Yes. You can use your home SIM alongside the eSIM to receive calls and texts as normal.

Most carriers allow this by default, but we recommend checking with your carrier before you travel – especially if you rely on one-time passwords. Incoming texts are usually free, while calls or outgoing messages may incur roaming charges depending on your carrier.

VOIP apps like Viber are affordable options. Simply add credit and use your eSIM data connection.

Use VOIP apps like Viber, or contact businesses via WhatsApp or email. Many hotels also provide guest landlines.

Yes, everything stays exactly the same. Your number, contacts, and chat history are preserved automatically.
