How does Simbye eSIM work for Ireland?
Set it up before you fly
After buying you get an email with a setup link and a QR code. Install the eSIM calmly at home on Wi-Fi — nothing is used up yet. The validity only starts when you first connect to a network in Ireland.
Switch it on after landing
Whether you arrive at Dublin (DUB), Cork (ORK), Shannon (SNN), Ireland West Airport Knock (NOC) or Kerry (KIR), or step off the ferry at Dublin Port or Rosslare: airplane mode off, data roaming on for the Simbye line, data off on your own SIM. You are online in a minute or two.
Top up as you go
Your account shows how much data is left at any time. When it runs low you top up in a few minutes — same eSIM, no new QR code, no reinstalling. Hotspot for a laptop, a tablet or the people you travel with is allowed.
Check Device Compatibility
Make sure your device supports eSIM before purchasing
Which networks will you be on in Ireland?
Your phone picks the strongest Irish network on its own — Vodafone, Three or eir, with nothing for you to set up.
The Simbye eSIM uses 3 networks in Ireland: Vodafone · H3G Ireland · Meteor Mobile Ireland.
| Networks | Download | Upload | Latency |
|---|---|---|---|
 | 95Mbit/s | 28Mbit/s | 33ms |

The eSIM is not tied to one operator. It may register on Vodafone, on Three (H3G Ireland) and on eir (Meteor Mobile Ireland), and it takes whichever comes in strongest where you are standing. If it loses that network on the way it can move to another one in the background. There is no APN to type in anywhere. If nothing connects at all, turn off automatic network selection in your settings, pick a network by hand, then switch back to automatic.
At Dublin Airport, Shannon and Cork Airport you are usually connected before you reach baggage reclaim. Dublin, Cork, Galway, Limerick, Waterford and Kilkenny are covered throughout, as are the M50 around Dublin and the motorways to Cork, Limerick and Galway. Killarney, Westport, Kinsale and Dingle town hold a steady signal too, and so do the ferry ports at Dublin Port and Rosslare. It thins out exactly where the good photographs happen: the R336 coast road through An Spidéal and Indreabhán in Connemara, the mountain roads of the Dingle and Beara peninsulas, large parts of Donegal and north Mayo, the valleys of the Wicklow Mountains and the Aran Islands. These dead spots hit every Irish SIM the same way — Vodafone is generally regarded as the steadiest of the three in the countryside. Download the map for the day's drive before you set off.
eSIM or a local SIM card in Ireland?
Ireland comes down to what you need: the eSIM is live as you land at Dublin Airport and keeps your own number reachable, while a shop card gets you an Irish +353 number. Belfast runs on UK networks either way.
| Feature |  Simbye eSIM |
Local SIM card |
|---|---|---|
| ID required | No | Ireland has no prepaid registration requirement, though a shop often wants a name and address to open an account |
| Online from when | The moment you land at Dublin Airport, because it was set up at home | Only after finding a shop, queueing and activating |
| How you get it | An email with a link and a QR code, installed in minutes | Vodafone, Three and eir shops, Tesco, Centra, SPAR |
| Data and validity | 1 GB to 20 GB, or an unlimited plan, 7 to 30 days | Whatever starter pack the shop has in stock that day |
| Price | Fixed before you travel, nothing added later | Starter pack plus credit, and it differs from shop to shop |
| Phone number | None, data only | An Irish number with the +353 dialling code included |
| Calls and texts | Only through apps like WhatsApp, FaceTime or Signal | Normally over the network, Irish landlines included |
| Northern Ireland and Belfast | Not included, that is UK networks | Depends on the operator and the plan, ask before you buy |
For most travelers the eSIM is the simpler choice: set up before departure, no queuing on arrival.

Frequently Asked Questions about Ireland eSIM
Data, calls, real phone numbers, top-ups and setup — everything you need to know before you buy a Simbye eSIM.
No, not in Northern Ireland or Belfast. Northern Ireland is part of the United Kingdom and runs on UK networks; this eSIM covers the Republic of Ireland only. The border is open and completely unmarked — you will not notice crossing it, but your phone will. If you are heading to Belfast, Derry or the Giant's Causeway you need a separate UK eSIM or a Europe eSIM that covers both.
Yes, an unlimited eSIM for Ireland exists. Plans run from 1 GB up to 20 GB, and there are unlimited options, with validity from 7 to 30 days. Choose by how you travel: a weekend in Dublin needs very little, while a fortnight on the Ring of Kerry with maps open all day, photos uploading and a hotspot for a laptop is where unlimited pays off.
No, you don't need ID or have to register. Ireland has no legal registration requirement for prepaid SIMs, and foreign eSIMs are not blocked there. You buy it online, an email with a QR code arrives, and nobody asks for a passport or an address.
Which network you're on in Ireland will be Vodafone, Three (H3G Ireland) or eir (Meteor Mobile Ireland), whichever comes in strongest. In Dublin, Cork and Galway it hardly matters, in the countryside it does.
Outside the cities in Ireland, coverage is good along the motorways. On the Ring of Kerry, in Connemara, in Donegal, on the Aran Islands and in the Wicklow Mountain valleys there are genuine dead spots. That affects every Irish SIM equally and comes down to the terrain, not the eSIM. Download maps for the day's route offline.
Yes, eSIM is available in Ireland. An eSIM for Ireland is a digital SIM card built into your phone. Irish networks support eSIM and carry data profiles for visitors, so your phone connects locally in Dublin, Cork, Galway and along the main routes. There is no plastic SIM to collect and nothing to arrange on arrival. Your phone simply needs to be eSIM-capable and carrier-unlocked, which the compatibility list on this page confirms.
You can buy an eSIM for Ireland online in a couple of minutes: choose a data plan from the table above, pay, and the QR code lands in your inbox. Install it over Wi-Fi before you fly, and it switches on by itself once you land. No shop visit and no waiting at an airport counter.
An eSIM in Ireland starts at 1,95€; the exact price depends on the data volume and validity you pick, shown in the table above on this page. A weekend in Dublin costs a fraction of a fortnight touring the west coast on maps and streaming. You pay once at checkout; nothing renews unless you buy again.
How much data you need for Ireland depends on your trip; a Dublin weekend needs barely 1 GB. A Wild Atlantic Way road trip with daily photo uploads and music sits nearer 500 MB a day, so 5-10 GB over a fortnight. Streaming or tethering a laptop in the evenings runs 1-2 GB daily, where unlimited saves you topping up.
The eSIM that's best for Ireland depends on your route: coverage where you drive, data volume, how long it runs, and whether you need an Irish number. This one registers on Vodafone, Three and eir and takes the strongest signal, 1-20 GB or unlimited for 7 to 30 days. Fine for maps, work and streaming, but it gives you no Irish number.
