Does my phone support eSIM?
On an iPhone, open Settings → Mobile Service (on some iPhones: Mobile Data): if there is an Add eSIM option, the phone has an eSIM. On Android, look for an option to add an eSIM in the SIM settings (Samsung: SIM manager → Add eSIM, in Samsung’s January 2025 guide SIM card manager → Add mobile plan; Pixel: Add SIM). Can’t find it? Look up your model in the list of eSIM-compatible phones.

The sums assume data every day at 0.8GB a day, the same norm as the data calculator; highlighted is the option that costs least. We compare each network’s public roaming passes and daily rates. Some plans have roaming built in (for example Vodafone Global Roam, O2 Ultimate, Three Complete and Sky Diamond VIP), so check your own plan. Network prices as published for their own customers; the eSIM at its price in pounds on 1 Nov, charged in pounds by card. For other days or other usage, work out your own trip. Every destination: roaming or eSIM, by country.

Frequently asked questions
How much does a day of mobile data cost in Ireland?
On plans with a fixed data allowance, £0.13 to £1.03 a day in Ireland: 3 GB for 30 days at £3.99 is the lowest daily price, 50 GB for 30 days the highest. The plan that costs least for the whole trip: for 7 days, 1 GB at £0.43 a day; for 15 days, 2 GB at £0.27 a day; for 30 days, 3 GB at £0.13 a day. Unused days are not refunded.
Which network does the eSIM use in Ireland?
Only 3 (4G): it is the single partner network for Ireland in the catalogue. Where 3 has no coverage, this eSIM has no signal either, so on a remote route check that 3 covers it.
What if the eSIM doesn't work when you land in Ireland?
Check, in this order: data roaming is on for the eSIM line, the eSIM is chosen as the line for mobile data, and aeroplane mode is off. The APN sets itself on this plan, so leave it as it is. Give the phone a few minutes to register on 3; that first registration is what starts the plan’s days. Still no connection? See what to check when the eSIM has no signal abroad.
General questions have their own pages: how card payment works, refund policy, how to install an eSIM and help and FAQ.
Prices come from our partner operator’s catalogue and may change; the amount at the moment of payment applies. We are not a mobile operator: network access is provided by the partner operator, under the plan’s terms. See the terms and the refund policy.
