Eir and travel eSIM in Ireland

Quick answer

  • 32 of the 104 Ireland plans we sell name Eir as a reachable network, at 5G.
  • eir runs LTE on B1, B3, B20, B28, B32 and 5G on n3, n78; your phone needs at least one of them.
  • Travel plans connect by roaming, so no plan can promise one specific network.

Eir in brief

eir states that its 5G network reaches 99 percent of the Irish population.

We are not a reseller for this operator and we have not run our own field speed tests. The band and network details below come from the sources listed at the end of the page.

Checked against the sources on 2026-10-12. Only the bands a source confirmed are listed; the network may run others too.

An eSIM can only use eir if your phone supports at least one band in this table. Before you fly, open your model's spec page on the maker's site and compare its LTE and 5G band lists.

eir's coverage map

eir publishes its own coverage map. Look up the street or district you will stay in rather than the country as a whole, because coverage in town and out of town differs a great deal. The map shows eir's own network; a roaming plan may not get every technology it shows.

Who licenses eir

Mobile networks in Ireland are licensed, and their spectrum assigned, by the Commission for Communications Regulation (ComReg). The bands above are the ones it allocates. A problem with the local network's own service goes to the operator first; a problem with your eSIM plan comes to us.

The plans on our shelf that name Eir

From the supplier record behind each package, 32 of the 104 plans we currently sell for Ireland declare Eir as a network the profile can reach, at 5G. The figure comes from the same catalogue that prices the plan pages, and it moves when the supplier revises the record.

A plan naming Eir means the network sits in the list the profile may choose from. It does not mean your handset will stay on it. The priority order is the supplier's, and the signal where you stand decides.

A band shared across networks is one a single phone can use on all of them.

Why plans do not name a fixed network

Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If Eir is weak where you are, try selecting Three Ireland or Vodafone Ireland manually in the network settings, and keep data roaming on for the eSIM profile.

FAQ

Will my eSIM definitely connect to Eir?+

32 of our plans name Eir as reachable, but that is not a guarantee. Travel plans run over roaming agreements, so the network depends on the supplier behind the plan, your device and where you are.

Which bands does my phone need for eir?+

At least one of these, LTE: B1, B3, B20, B28, B32; 5G: n3, n78. Your phone's band list is on the maker's spec page for your model, under "Cellular" or "Network".

Does Eir run 5G, and will my plan get it?+

Yes. eir has run commercial 5G, on n3, n78. A travel plan only gets it when the plan permits 5G, your phone supports one of those bands, and you are inside 5G coverage. Miss any one and you fall back to 4G.

How do I see which network I am on?+

Check the carrier name at the top of the screen, or open the mobile-network settings and look at the operator list. If signal is poor, try selecting a network manually instead of automatic, but only one your plan actually supports.
