eSIM Travel Tips for Dublin

Activate your eSIM before you leave Changi
Buy your HelloRoam eSIM for Dublin before your flight from Singapore Changi Airport. Scan the QR code at home on Wi-Fi, enable data on arrival, and you are connected in Dublin without searching for a local SIM card at the airport.
Keep your Singapore number active on dual SIM
On a dual SIM device, keep your Singtel, StarHub, or M1 SIM active for calls and texts from Singapore. Set HelloRoam as your data line for Dublin. Family and colleagues in Singapore reach you on your regular number without international charges.
Download offline maps before your flight
Download Google Maps or Maps.me offline for Dublin before leaving Singapore. This saves data on detailed map downloads and keeps you covered in areas with weaker signal during your first hours in Dublin.
Compare with Singtel and StarHub roaming costs
Singtel, StarHub, and M1 all offer international roaming add-ons for Ireland. For stays of a week or more, a HelloRoam eSIM starting at $2.68 works out cheaper per GB of data used.
Check entry and visa requirements before flying

Dublin is a popular destination for Singapore travellers throughout the year. The ideal period depends on local seasonal conditions. Check weather patterns for your travel dates and book early for peak school holiday periods in Singapore.

Airport and Transit Connectivity

Dublin Airport (DUB) has 4G and 5G coverage across Terminal 1 and Terminal 2. Your HelloRoam eSIM connects to the network before you reach the arrivals gate. The Aircoach and Dublin Express bus services connect the airport to the city center in 30 to 45 minutes with outdoor 4G throughout.

The Dublin Bus 16 and Airlink 747 routes also run from the airport. The Luas Green Line runs from the suburbs to central Dublin and the DART connects the coastline. Dublin city center has no metro system, so buses and trams are the main public transport.

The Dublin Bikes app and various car rental apps all need live data. Singapore-based travellers should activate their eSIM before departure so data is ready on arrival.
