Option 2: Local SIM Card in Dublin
You can also buy a prepaid Irish SIM card after arrival.
Where to Buy SIM Cards in Dublin
Tourists can usually buy SIM cards at:
- Dublin Airport
- Vodafone / Three / Eir stores
- shopping centres
- supermarkets
- convenience stores
Local SIM cards can be useful for longer stays, but they are less convenient if you need internet immediately after landing.
Possible downsides:
- queues after arrival
- ID registration may be required
- time spent finding a shop
- manual setup
- possible physical SIM swap
Option 3: International Roaming
Roaming is convenient because your phone connects automatically to a local Irish network.
However, roaming can become expensive depending on your mobile provider and home country.
Roaming may be suitable if:
- your plan includes Ireland
- you only need very light data
- you do not want to change any settings
But for many non-EU travelers, eSIM or local SIM is usually better for cost control.
