よくある質問

Does an Ireland plan work in Northern Ireland?+

Usually not, because Northern Ireland is part of the United Kingdom and appears as a separate country on a plan's list. The catch is that the border has no checkpoint and no clear signage, so drivers heading north to Belfast or the Giant's Causeway cross without noticing and lose data mid-route. If the north is on your itinerary, pick a plan that names both Ireland and the United Kingdom, or a Europe plan covering both.

Data drops on the west coast — how should I prepare?+

Before leaving town, download the offline map for the area and set the full route while you still have signal — turn-by-turn keeps working without data because GPS positioning does not need it. Save your accommodation's phone number and address as plain text too, since some spots carry a call but will not load a web page. Plan on stretches of ten kilometres or more with nothing on the peninsulas.

What is an Eircode and why do I need one?+

An Eircode is a seven-character postcode that identifies one individual property, unlike postcodes elsewhere that cover a whole district. In rural Ireland many houses share a road name with no numbers at all, so searching by name alone often lands you somewhere else entirely. Ask your accommodation for its Eircode when booking and paste it straight into the map app to arrive at the actual door.

Should I buy unlimited for a ten-day trip?+

Usually not. Ten days of driving with navigation running tends to total around 12–18GB, which a mid-size plan handles. Unlimited only pays off if you stream every night, upload high-resolution video, or hotspot the whole carload at once. Estimate from what you actually use per day at home and add an allowance for maps — that lands much closer than guessing.

When does a Ireland eSIM start counting days?+

Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.

Do I have to remove my home SIM?+

No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
