It's crucial to note that our standard Republic of Ireland eSIMFlyer plans are specifically valid within the Republic's borders. If your itinerary includes crossing into Northern Ireland (part of the UK) – for example, driving from Dublin to Belfast or visiting the Giant's Causeway – your connection will cease at the border. For seamless travel across both Irelands, we recommend exploring our regional or multi-country eSIM plans. These are designed for frequent flyers whose journeys often span political boundaries, ensuring continuous connectivity without interruption.
HELP CENTER
Does this eSIMFlyer plan cover both the Republic of Ireland and Northern Ireland (Belfast, Giant's Causeway), or just the Republic?
