eSIM data plans for Ireland

Ireland eSIM plans come in two shapes: a set amount of data that lasts for a fixed number of days, or unlimited data sold by the day. Hotspot and tethering are available on every plan, so a laptop or second device can share the connection regardless of which type is chosen.

Picking between the two plan types

Short trips with light use suit a fixed data plan: a few days of maps, messaging and browsing rarely need more than the smaller sizes. Longer stays, or trips built around streaming and video calls, suit either the larger data sizes or one of the unlimited day plans, since both scale with how many days are booked.

Fixed data plans

These plans run on Meteor Mobile and Vodafone, both 4G and 5G, in sizes from 1GB up to 50GB with validity from 7 to 30 days. If the data is used up before the trip ends, a top-up on the same eSIM restores it, so a smaller size can be chosen at first and extended later if it is not enough.

Unlimited plans

Eir and Three carry the unlimited plans, on 3G and 4G, sold in single days from 1 to 30. Each day of the plan carries a fair use policy: once a daily amount of use is passed, speed is reduced for the rest of that day. This makes the unlimited plans a straightforward choice for anyone who would rather pick a number of days than track a data amount.

Buying ahead of the trip

Validity begins the moment the eSIM first connects to a network in Ireland, not at purchase or installation. Installing it before departure costs nothing extra, so it can be set up in advance and left ready to activate on arrival.
