What the network is actually like

Dublin and the larger towns are fine. The west coast and the midlands are noticeably patchy. The Wild Atlantic Way has long stretches with nothing. Note Ireland uses UK-style plugs despite being in the Eurozone.

This eSIM: up to 3G, 4G, 5G, onEir. Each plan on the Ireland page says which of these it uses.

How much data you'll need

5GB does a week, though anything west of the Shannon wants offline maps.

Recommended: 5GB → closest plan 5GB · 30 days, $4.76.
