Ireland eSIM
data from $2.59.

If you want an Ireland eSIM, buy a data only plan before you fly and let it connect to 3, Vodafone or Eir automatically on arrival. Slashtel Ireland plans start from $2.59, work on 5G where available, and keep your home SIM free for calls and bank codes. No shop visit, no local number, no roaming bill.

Choosing an eSIM for Ireland

What matters is simple: a plan that connects to the main Irish networks, carries enough data for your trip, lasts long enough, and is installed before you leave home.

Travellers often search for the best eSIM for Ireland, then get lost in fine print. Judge any plan on these points instead:

• Coverage on the main networks. In Ireland that means 3, Vodafone and Eir. A plan that can use all three gives you the widest choice of signal as you move between cities, coast and countryside.
• Enough data. Maps, messaging and booking apps are light. Video, hotspot use and long days of photo backups are heavy. Match the size to the trip, not to the biggest number on the page.
• Validity. Your plan runs for a set number of days. Pick a duration that covers the whole trip, including the day you land and the day you leave.
• Hotspot support. If you plan to share data with a laptop or a travel companion's phone, check that tethering is included in the plan you choose.
• Installing before the trip. Add the eSIM at home over your own wifi, so the first thing that happens at Dublin Airport is a working connection, not a download on airport wifi.
• A data only design. There is no local number and no calls or SMS. That keeps the product simple and lets you keep your home number active for bank codes and calls.

Plans and prices for Ireland

Ireland plans come in six data sizes and four durations, so you can buy a small weekly plan or a long stay plan without paying for data you will not use. Prices start at $2.59.

The sizes are 1GB, 3GB, 5GB, 10GB, 20GB and 50GB. Durations are 7, 15, 30 and 180 days. The table below shows the plan options and the live price for each size.

Prices are shown in US dollars and are the live from price for each size. The longer validity periods suit students, remote workers and anyone visiting family for an extended stay. If your trip is shorter than the plan duration, that is fine. You simply use the plan while you are there and the remaining days are not needed once you leave.

Networks and coverage in Ireland

The Ireland eSIM connects to 3, Vodafone and Eir, and the network is chosen automatically. You do not pick one manually.

That automatic selection is useful in Ireland because signal strength varies by place. A phone that can attach to any of the three main networks has more options in towns, along the coast and in rural areas. Your device will attach to a suitable network when you arrive and re select as you move.

In practice:

• Dublin and other cities are well served, and 5G is available on compatible devices where the network provides it.
• The Wild Atlantic Way passes through long stretches of coast and small towns. Coverage exists along the route, but expect the signal to change as you drive between settlements.
• Visiting family in towns and suburbs is usually straightforward. Inside older buildings, thick walls can weaken any signal, so try a window if a call over data drops.

The eSIM supports 5G on capable handsets. If your phone is older, it will use 4G or whatever generation is available locally. You can check your device against the compatibility guide.

How much data you need

Most travellers need less than they think. A one week trip with normal messaging, maps and a little browsing fits comfortably in a small plan, and heavier users should step up one size.

The sizes on this page map neatly to common trips:

• One week: 1GB over 7 days is the published starting point. Light users who lean on wifi in hotels and cafes will find it enough for maps, messaging and check ins.
• Two weeks: 3GB over 15 days suits a normal holiday pace with some photo sharing and occasional video.
• One month: 3GB over 30 days covers a longer stay with regular but modest use, and larger sizes are there if you stream or work remotely.
• Coastal road trips: if you navigate all day, upload photos and share a hotspot, choose 5GB or 10GB for 30 days.
• Long stays and family visits: 20GB or 50GB over 180 days gives room for video calls home, streaming and everyday use.

A simple rule: count the days, decide whether you will stream video or use hotspot, then pick the size above your estimate. Topping up later is possible if you run low.

Install it before you fly

Add the eSIM to your phone at home, over wifi, before you travel. The install takes a few minutes and saves you from hunting for a connection after landing.

Steps for most phones:

1. Buy the Ireland plan on slashtel.com and open the install instructions in your account.
2. Connect to your home wifi.
3. Add the eSIM in your phone settings and label it Ireland so you can tell it apart from your home SIM.
4. Leave the eSIM switched off until you are ready to travel, or switch it on at the airport.
5. On arrival, enable the eSIM and turn on data roaming for that line only. The network is chosen automatically.

Full steps for iPhone and Android are in the install guide. Keep your home SIM in the phone but set it as the line for calls and texts, and set the Ireland eSIM as the line for mobile data. That combination keeps your number active for bank codes while data comes from the local plan.

Calls, texts and your home number

The Ireland eSIM is data only. It has no local phone number and cannot make ordinary calls or send SMS. WhatsApp, FaceTime and similar apps work over the data connection.

That suits most travellers. You message family, book tables and check maps over data, and you keep your home SIM in the phone for incoming calls and bank verification codes. When you call home, use WhatsApp or FaceTime over the Ireland data, which avoids international call charges on your home line.

A few practical notes:

• Keep your home SIM enabled for calls and texts, but make sure its data roaming is off so you do not pay your home operator for data.
• Set the Ireland eSIM as the default line for mobile data.
• If a banking app needs an SMS code, your home number receives it as normal, provided your home operator allows roaming for texts.
• If you use hotspot, remember it draws from the same data allowance.

Questions travellers ask about Ireland

Short answers to the things people ask most before buying an Ireland eSIM.

Can I make calls and texts? No. The plan is data only, with no local number. Use WhatsApp or FaceTime over data for calls, and keep your home SIM for texts and bank codes.

Does WhatsApp work? Yes. Messaging, voice notes and calls in WhatsApp run over the data connection, as do FaceTime and similar apps.

Is hotspot included? Yes, you can share your data with a laptop or another phone. Shared data counts against your allowance, so watch it if you tether often.

When does the plan start? The validity period begins when the plan first connects to a network in Ireland, not when you buy it. Installing early does not start the clock.

Can I top up? Yes. If you run low you can add another plan from your account and keep using the same eSIM.

Which phones work? Most recent iPhones and Android phones support eSIM. Check the compatibility guide before buying.
