Which Ireland eSIM plan fits your trip?

Choose your Ireland eSIM by matching the allowance and validity period to your trip, then compare the selected product details with the local network, band and speed references already shown on this page.

Start with the length of your stay, then allow for navigation, messaging, streaming and work use. Each option below is a plan size that is currently available for this destination.

Short trip

1 GB / 7 days

Best for: A short visit with maps, messages and occasional browsing.

This option pairs the 1 GB allowance with a stated validity period of 7 days.

Usage tip: Save maps before longer journeys and use Wi-Fi for large downloads.

Two-week trip

3 GB / 15 days

Best for: A stay of around two weeks with regular navigation and messaging.

The 3 GB allowance remains available across a stated validity period of 15 days.

Usage tip: Keep automatic app updates and cloud backups on Wi-Fi.

Longer or higher use

10 GB or more / 30 days

Best for: A longer stay or more frequent streaming, video calls or work use.

The 10 GB or more / 30 days profile provides a larger data pool than the short-trip options on this page.

Usage tip: Compare the allowance with your normal phone usage and monitor it during the trip.

Coverage in Ireland

Rural western regions (Connemara, parts of Donegal, Kerry) have large areas with no service on any network. No operator runs a 3G-only network; all have shut down 3G or are in the process. Band B28 (700 MHz) is used by Three and Eir but is absent from some North American phone variants.

How to check mobile coverage in Ireland

The Ireland mobile network source is linked below as a public network reference. Check the places on your itinerary where the source offers local detail, then confirm the network information for the selected eSIM product. The operator table on this page provides the country-level reference, while the selected product details identify which network information applies to your plan.

Accommodation and daily stops

Check your accommodation and the places you expect to visit in Ireland. Indoor reception can differ from an outdoor map, so keep the property Wi-Fi details available as well.

Journeys between stops

Review the full route rather than checking only the arrival city. Save tickets, addresses and maps offline before longer road or rail journeys.

Borders and onward travel

Check the selected product scope for every country on your itinerary. Your Ireland plan and a regional plan may have different included destinations and validity periods.

Phone compatibility in Ireland

Compare your phone with 4G bands B1, B3, B8, B20, B28 and 5G bands n3, n78 in the existing Ireland network table. Support for more of the listed bands gives the phone more options when connecting, while the selected product, location and local network conditions determine the service available.

Set up the Ireland eSIM for your trip

Keep the QR code and installation instructions available offline, and complete each step according to the selected product's instructions.

When validity starts: Validity-start rules can differ by product. Check the selected plan details before installation and travel.

  1. Confirm that your phone is unlocked and supports eSIM before purchase.
  2. Save the QR code or manual installation details somewhere you can reach without mobile data.
  3. Use reliable Wi-Fi to install the profile at the time recommended in the product instructions.
  4. When you are ready to use it, select the travel eSIM for cellular data and apply the stated roaming and APN settings.
  5. Keep roaming disabled on your home line if you want to avoid using its travel data.

How to Enjoy Ireland

From the lively streets of Dublin to the quiet countryside, Ireland offers a mix of urban energy and natural calm. Dublin rewards visitors with historic pubs, live folk music, and easy walks along the River Liffey. For a more relaxed pace, head west to County Galway or the Dingle Peninsula. Renting a car gives you freedom to explore small villages and coastal viewpoints at your own speed.

Whether you prefer guided tours or independent wandering, the Irish are famously welcoming. Strike up a conversation in a local pub - you will often hear traditional music sessions that start unprompted. Many towns host weekly markets where you can buy local cheese, crafts, and fresh produce. To avoid crowds at popular sites, arrive early or book tickets in advance online.

Top Attractions in Ireland

Cliffs of Moher in County Clare rise dramatically over the Atlantic Ocean. Visit early morning or late afternoon for thinner crowds and better light. Dublin's Guinness Storehouse ends with a pint at the Gravity Bar, which offers a 360-degree view of the city. Book your time slot ahead.

Newgrange is a prehistoric passage tomb older than Stonehenge. Access is by guided tour only, and tickets sell out weeks in advance. Ring of Kerry in County Kerry is a scenic drive with stops for photos, short walks, and small cafes. Trinity College Dublin houses the Book of Kells and the Long Room library. Queues can be long; an early morning visit is smart. Whether you choose natural wonders or city culture, each site benefits from advance planning.

Must-Try Irish Foods

Irish Stew is a hearty one-pot meal of lamb or mutton with potatoes, carrots, and onions. It appears on most pub menus, especially in colder months. Colcannon - creamy mashed potatoes blended with kale or cabbage - is a traditional side often served with ham or bacon.

Soda Bread is a dense, slightly sweet loaf that uses baking soda instead of yeast. Try it fresh with butter. Seafood Chowder, especially along the west coast, is rich with smoked fish, cream, and herbs. Boxty is a Northern Ireland specialty: a potato pancake that can be fried or boiled. From creamy chowders to rustic breads, Irish food relies on simple, good ingredients. Look for daily specials in small pubs rather than tourist-heavy restaurants.

Best Time to Visit Ireland

Late May, June, and early September offer the best balance of mild weather, long daylight, and manageable crowds. July and August are warmest but also busiest and most expensive. May and September often have fewer tourists and still pleasant conditions.

Winter and early spring (November through March) bring shorter days, more rain, and some closed attractions. However, you will find lower prices and a quieter experience. December brings festive Christmas markets in Dublin and Cork. If you plan outdoor activities like hiking the Ring of Kerry or visiting the Cliffs of Moher, aim for late spring or early autumn. Irish weather is famously changeable, so expect rain in any season and pack accordingly.

What to Pack for Ireland

Waterproof jacket - not just water-resistant. A hood is essential. Layers such as fleece, sweater, and a light mid-layer let you adjust to sudden shifts in temperature. Sturdy walking shoes with good grip are vital for uneven paths, wet grass, and coastal trails. Portable charger for long days away from outlets. Universal power adapter (Ireland uses Type G plugs with three flat pins).

Prepare for rain at any time of year. Lightweight, quick-drying fabrics are more practical than heavy wool. Sturdy shoes double for city sightseeing and country walks. Portable chargers and adapters solve common travel frustrations. Ireland's weather can change in minutes, so keep a waterproof layer and a spare sweater in your daypack.

Common Questions

The details worth knowing about your Ireland eSIM

This eSIM is for the Republic of Ireland only. Mobile networks in Northern Ireland are operated by UK providers, not by Vodafone, Three, or Eir. Your data will not roam across the border. Consider a separate UK eSIM if you cross into Northern Ireland.

Three and Eir use band B28 (700 MHz) for 4G, which travels farther in rural areas like Connemara or Donegal. Many North American phone variants lack B28. If your phone does not support B28, you may have similar coverage gaps to Vodafone users in these western regions.

Your eSIM will automatically select a partner network, typically based on signal strength. You cannot manually choose which operator to connect to. The eSIM may latch onto any of the three networks: Vodafone, Three, or Eir, depending on availability at your location.

5G is available on networks n3 (1800 MHz) and n78 (3500 MHz), which all three operators—Vodafone, Three, and Eir—support. Whether you get 5G depends on your phone’s compatibility with these bands and your proximity to a 5G tower. No 5G coverage exists in many rural western areas.

No registration or ID is required to use this eSIM in Ireland. Irish law does not mandate personal identification for prepaid mobile data services. You simply install the eSIM and activate it. No passport or local registration steps are needed.

Compare 1 GB / 7 days, 3 GB / 15 days and 10 GB or more / 30 days. Use the shorter profiles for lighter maps and messaging use, then compare the larger allowance for streaming, video calls or work apps.

The start rule is product-specific. Review the selected plan details before installing it so you know whether any action is required before arrival.
