eSIM Travel Tips for Budapest

Activate your eSIM before you leave Changi
Buy your HelloRoam eSIM for Budapest 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 Budapest 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 Budapest. Family and colleagues in Singapore reach you on your regular number without international charges.
Download offline maps before your flight

Compare with Singtel and StarHub roaming costs
