Prepaid data plans for every type of Irish trip
esimbloom lists 59 prepaid eSIM plans for Ireland from $0.38 (the smallest is 500MB for 1 day). Every plan is data-only — mobile internet for maps, messaging and bookings, but no local phone number or SMS — and prepaid: pay once, no contract, no roaming charges.
How to activate your Ireland eSIM before you fly
Check that your phone supports eSIM—most iPhones from XS onward, recent Samsung Galaxy and Google Pixel models, and many other flagships do. After purchase, you'll receive a QR code by email within minutes. Install the eSIM before your flight by scanning the code in your phone's settings, then label it something like 'Ireland Data' so you can identify it later.
Keep your home SIM active for calls and texts, and set the eSIM as your data line. Turn on data roaming for the eSIM only. The plan will connect automatically when you land in Ireland. If it doesn't, toggle airplane mode or restart your phone. You can top up or buy another plan from your email if you run low.
Staying online across the island
Mobile coverage in Ireland is strong in cities and towns. Dublin, Cork, Galway, and Limerick all have reliable coverage, and you'll stay connected on intercity trains and buses along major routes like the Dublin–Cork and Dublin–Galway lines. The Wild Atlantic Way coastal drive and Ring of Kerry are generally well covered in villages and tourist areas, though signal can drop in remote stretches between towns.
If you're driving through Connemara, the Burren, or Donegal's interior, expect occasional dead zones in valleys and mountain passes. Most travellers use 1–3GB per week for navigation, WhatsApp, and posting photos. If you're uploading video from the Cliffs of Moher or streaming on long drives, budget closer to 5–7GB. Accommodation and cafés in tourist areas usually offer Wi-Fi, so save large downloads for those times.
Frequently asked questions
How much does an eSIM for Ireland cost?
esimbloom Ireland eSIM plans start at $0.38, with 59 plans to choose from. You pay once for the plan you pick — no roaming fees and no contract.
Do I need an eSIM for Ireland?
Only if you want mobile data without roaming charges. An esimbloom Ireland eSIM is installed from a QR code before you fly, activates on your first connection in Ireland, and is data-only — your home SIM stays in the second slot for calls and SMS, with its data roaming switched off.
Will my eSIM work throughout Ireland, including Northern Ireland?
Your eSIM covers the Republic of Ireland. Northern Ireland is part of the UK, so you'll need a separate UK plan or a regional Europe plan that includes both. Check the plan description before purchase if your trip crosses the border.
Can I use my Ireland eSIM as a hotspot?
Yes, most plans allow tethering. You can share your connection with a laptop or tablet. Keep in mind that hotspot use drains your data allowance faster, especially if other devices are syncing or updating in the background.
Do I get an Irish phone number with my eSIM?
No. esimbloom plans are data-only, so you won't have a local number for voice calls or SMS. Use WhatsApp, FaceTime, or other internet-based apps to stay in touch. Your home number remains active if you keep your original SIM installed.
When does my plan validity start?
Validity begins when the eSIM first connects to a mobile network in Ireland, not when you install the QR code. You can set up the eSIM at home and it will activate automatically on arrival, so your full validity period is available for your trip.
What happens if I use all my data before the plan expires?
Your data stops, but the eSIM stays installed. You can purchase a top-up or a new plan from the email receipt and install it as a second eSIM, or simply wait until you're back on Wi-Fi. There are no overage charges.
