Mobile coverage guide for Singapore
Singapore is one of the most connected cities on earth and a favourite stopover for Australians on the way to Europe, as well as a destination in its own right. HelloRoam plans connect on StarHub, which covers every corner of the island on 4G and 5G.
You're online the moment you arrive at Changi, regularly voted the world's best airport, and the signal holds from Marina Bay to the heartland suburbs.

eSIM Travel Tips for Singapore
Singapore as a stopover destination
Many Australians break up their long-haul European journey with a Singapore stopover. Even a 24-hour stopover in Singapore is enough to see Gardens by the Bay, eat at hawker centres, and walk the Marina Bay waterfront. Your HelloRoam eSIM keeps you connected the moment you exit Changi.
The MRT and data for navigation
Singapore's MRT is excellent and covers the whole island. Google Maps handles MRT navigation well and works perfectly with your HelloRoam data connection. Buy an EZ-Link card or use Visa payWave on the turnstiles rather than carrying cash.
Heat and humidity management
Singapore sits about 1 degree north of the equator. It is hot and humid every day of the year, typically 28 to 34 degrees Celsius. Keep your phone out of direct sun and use the MRT or taxis between outdoor sightseeing spots to avoid overheating yourself and your device.
Hawker centres and Google Translate
Singapore's hawker centres serve Malay, Chinese, and Indian food with menus in multiple languages. Google Translate camera mode works brilliantly with your HelloRoam data. Lau Pa Sat, Maxwell Food Centre, and Old Airport Road are all worth visiting.
Connecting to regional trips
Singapore is a hub for travel to Malaysia, Indonesia, and the rest of Southeast Asia. You will need separate HelloRoam plans for each country you visit. Buy them all before you leave Australia rather than figuring it out mid-trip.
Mobile networks in Singapore: Singtel, StarHub, and M1
Singapore's main carriers are Singtel, StarHub, M1, and Simba. They cover the island densely, and dead zones are close to non-existent. HelloRoam plans connect on StarHub, which runs 4G and 5G across the CBD, the MRT network, Sentosa, and Changi. Singapore is one of the few places where you're unlikely to lose signal.

Best time to visit Singapore from Australia
Singapore is a year-round destination with no real off-season because the weather is consistently hot and humid regardless of month. February is the driest month. The wet season from November to January brings more frequent afternoon downpours. The formula racing season in September (Singapore Grand Prix) fills up the city fast. Chinese New Year in January or February is a vibrant but busy time.
