Ireland eSIM

Legally, no — the Common Travel Area means British citizens don't have to show one. But some airlines and ferry companies ask for a passport under their own ID rules, so check with your airline or ferry company before you leave. Visitors from the US, Canada, Australia and New Zealand can enter visa-free; other nationalities may need one.

In the regulator's 2025 consumer survey, rural users reported losing signal more often than urban ones. Before a drive along the west coast, look the address up on ComReg's official coverage map and pick a plan that lists both networks.

Most travellers don't: WhatsApp keeps working on your existing account. Plans that include a local number say so in their details.

Eir Mobile, Three, eir. Which one you connect to depends on local signal.

Yes. Operators here are listed with 5G; each plan's networks show which.

It depends on the plan: some keep a usable speed of 1 Mbps / 5 Mbps; others drop to 128 Kbps / 384 Kbps / 500 Kbps / 512 Kbps, which is enough for messaging; others stop data.

It starts when the eSIM first connects to a network. You can install it before you go.

41 of these plans state personal hotspot support, so you can share data with a laptop or travel companions. It comes out of this eSIM’s allowance. Look for “Personal hotspot” in the plan details.

No. Each QR code installs once. If you delete the eSIM or reset the phone, it can't be installed again, and once it has connected to a network it can't be refunded.

Some plans add data, some add days, and some can't be topped up; each plan says which. Top up from the eSIM in My eSIMs. There's nothing new to install.

Yes. The listed price is the final price.
