A HelloRoam eSIM means you arrive in Singapore connected without hunting for a SIM card at the airport.

eSIM Travel Tips for Singapore
Sort your data before your flight from Dublin
Buy your HelloRoam eSIM for Singapore at home, activate it over Wi-Fi, and enable data when you land at Changi Airport. You skip the terminal SIM card counters and step off the plane already connected. Useful when you have a tight connection.
Keep your Irish number active
On a dual SIM phone, keep your Eir, Three IE, or Vodafone IE SIM for calls and texts while using HelloRoam for data in Singapore. Family and colleagues back in Ireland can still reach you on your regular Irish number.
Offline maps save data on city breaks
Download Google Maps for Singapore offline before you leave Ireland. Coverage is excellent throughout the city state. Singapore's MRT is straightforward with live maps, and Grab (the local ride-hailing app) works well on a local data connection.
Travel insurance and emergency numbers
Keep your travel insurance details to hand. In Singapore, dial 999 for police and 995 for ambulance and fire. Save these before you fly. Your HelloRoam eSIM keeps your insurer's app, the Irish embassy in Singapore, and navigation tools accessible throughout your trip.
Currency and card acceptance
Notify your Irish bank before travelling to Singapore. Card acceptance is generally good in Singapore but carry some local currency for smaller vendors and public transport. Currency conversion apps work well on a HelloRoam data connection.
Mobile networks in Singapore: what Irish visitors need to know
HelloRoam connects on StarHub in Singapore. StarHub offers 5G coverage across Singapore including Changi Airport, Orchard Road, Marina Bay, and the city's MRT stations. Your eSIM connects automatically on arrival.
