The 7 Best eSIMs for Ireland: From Short Visits to Longer Stays

Tourism in Ireland 🍀 is booming — but finding reliable WiFi isn’t always guaranteed. Whether you’re pub-hopping in Dublin or road-tripping the Wild Atlantic Way, staying connected makes life easier.

Sure, you could just turn on roaming and hope for the best. But roaming charges add up fast — and the last thing you want is a nasty surprise when you get home.

eSIM is the modern fix.

What is an eSIM?

It’s a digital SIM you download directly to your phone, giving you local data, calls, and texts across Ireland — no plastic SIM cards, no swapping, and no roaming fees.

Setup takes just a few minutes in your phone’s settings. Your regular SIM (and phone number) stays active, so you can still receive calls from home if needed. And when your trip is complete? You can delete the eSIM plan and revert to your original plan in seconds.

Will my phone work with eSIM?

Most newer phones support eSIM — but it’s always good to double-check. Here’s how to know if your phone is compatible:

• iPhone: iPhone XR and newer (including all iPhone 11, 12, 13, 14, and 15 models)
• Samsung: Galaxy S20 and newer, Z Flip/Fold models, Note 20 and newer
• Google Pixel: Pixel 3 and newer (except Pixel 3 models from Australia, Japan, and Taiwan)
• Other brands: Many newer Oppo, Huawei, Motorola, and Sony devices — check your device settings

How to check on your phone:
Go to Settings > Mobile Data (or Network & Internet) and look for an option like “Add eSIM” or “Add Mobile Plan”.

How do you choose the right plan?

It mostly depends on how long you’re staying and how much data you plan to use. Light user just needing maps and WhatsApp? A small plan will do. Streaming, hotspotting, or remote working? Go for a bigger bundle. But remember, the more data you buy the cheaper it gets per GB — great news for all you long haul travellers!

🔥 PRO TIP: Look out for our Lycamobile 100 GB plan: 20 cents per gigabyte is unbeatable value. 🔥
