Local Pricing Context
Ireland's mobile market is served by three main carriers — Three Ireland, Vodafone Ireland, and Eir — with Three commanding the largest prepaid market share. As an EU member, Irish SIMs include EU-wide roaming at no extra cost, making a Dublin-purchased SIM excellent value for travelers continuing to continental Europe or the UK (which has separate roaming arrangements post-Brexit, but many Irish plans still include UK roaming).
Three Ireland's "All You Can Eat" prepaid plan is the standout tourist option: €20 for 28 days of unlimited data, calls, and texts within Ireland plus EU roaming. This is genuinely unlimited — no throttling, no fair-use cap for typical tourist usage. It's widely considered one of the best-value mobile plans in Europe. A Three SIM card costs €5 for the chip, loaded with €5 credit.
Vodafone Ireland's prepaid "X" plans start at €20 for 30 days with 15 GB of data. Eir's prepaid options are similar at €15–20 for 10–15 GB. Both offer adequate coverage but neither matches Three's unlimited data proposition at the same price point.
SIM cards are available at Three, Vodafone, and Eir stores on Grafton Street and Henry Street (Dublin's main shopping areas), in Dundrum Town Centre, and at convenience stores (Centra, Spar) throughout the city. Dublin Airport has carrier kiosks in Terminal 1 and 2 arrivals — prices are identical to city stores, making airport purchase convenient.
Registration is straightforward — present your passport at the store and the SIM is activated within minutes. No biometric data is required, and the process is faster than in most European countries.
eSIM support is available from all three carriers. Airalo offers Ireland plans from $4.50 USD for 1 GB / 7 days, but at €20 for unlimited data from Three, a physical SIM is hard to beat for any stay over a few days.
Dublin's WiFi coverage is extensive — virtually every pub, café, and hotel offers free WiFi. The "Dublin City WiFi" network provides free coverage in selected public areas around the city center.
How to Avoid Overpaying

- 2Dublin Airport carrier kiosks sell at the same price as city stores — buy on arrival without penalty
- 3Three's plan includes EU roaming — one SIM covers Dublin, Paris, and Barcelona on a multi-city trip
- 4At €20 for unlimited data, physical SIMs beat every eSIM option for stays over 3 days
- 5Pick up the SIM chip for €5 at any Centra or Spar, then add the €20 plan — no need to visit a carrier store
