You do not get a new phone number with this eSIM.
Setting up your eSIM? The installation and activation guide walks through it step by step, and the full FAQ covers device compatibility, hotspot, dual SIM and topping up.
One plan covers the Republic of Ireland, so the same eSIM works in Dublin, Galway and Cork and out along the Wild Atlantic Way and the Ring of Kerry. Install it before you fly, switch off airplane mode on arrival, and you are online for maps and bookings straight away.
The eSIM connects automatically when you turn off airplane mode at Dublin (DUB), Cork (ORK) or Shannon (SNN). Your airport coach, car-hire shuttle and maps are ready the moment you land - handy before a long drive west.
Ireland's networks - Vodafone, Three Ireland and Eir - give 4G/LTE and growing 5G across Dublin and the towns, with reliable coverage on the main roads. Signal naturally thins in the rural west - Connemara, the Kerry mountains and parts of Donegal - and along remote stretches of the Wild Atlantic Way, so download offline maps for those drives.
This plan covers the Republic of Ireland. Northern Ireland (Belfast, the Giant’s Causeway, Derry) is part of the United Kingdom, so if your trip crosses the border you will want a UK plan for that leg, or a Europe regional plan that includes both.
No. This plan covers the Republic of Ireland. Northern Ireland is part of the UK, so use a United Kingdom plan there, or a Europe regional plan if your trip spans both.
Coverage is good in the towns and on the main routes. Remote headlands, mountain passes and parts of Connemara and Donegal can drop out, so save offline maps for the scenic drives.
For most visitors from outside the EU, yes - a prepaid travel eSIM bought before you go is usually far cheaper than pay-as-you-go roaming for the same amount of data.
