eSIM Travel Tips for Singapore
Singapore is a popular stopover and destination
Many British travellers stop in Singapore on their way to Australia, New Zealand, or Southeast Asia. A HelloRoam eSIM covers Singapore whether you are on a short stopover, a week-long stay, or using it as a hub for onward travel through Southeast Asia.
Currency in Singapore
Singapore uses the Singapore dollar (SGD). Current exchange rates are roughly £1 to 1.70-1.75 SGD. Singapore is expensive by regional standards, comparable to London for hotels and restaurants but more affordable for hawker centre food and public transport.
Singapore's MRT is excellent
Singapore's Mass Rapid Transit (MRT) network is comprehensive, air-conditioned, and very easy to use. Your HelloRoam eSIM keeps Google Maps and the MyTransport.SG app working for real-time MRT journey planning. Download maps before exploring to save data.
Coverage reaches the whole island
Singapore's tiny geographic area (728 sq km) means network infrastructure is incredibly dense. You will have 5G or 4G virtually everywhere, in MRT tunnels, shopping malls, hawker centres, and even on Sentosa Island beaches. There are no meaningful coverage dead zones.
Keep your UK SIM active for onward travel planning
If Singapore is a stopover on a longer journey, keep your UK SIM active for calls and texts from home. Your HelloRoam eSIM handles Singapore data. For onward travel to other countries, check HelloRoam's plans for your next destination.
Mobile networks in Singapore: what British travellers need to know
Singapore has three main mobile operators: Singtel, StarHub, and M1, with Simba as a fourth player. HelloRoam connects on StarHub, which offers 5G across the city-state and 4G LTE everywhere else. Singapore consistently ranks among the world's top countries for mobile network quality and speeds, so coverage is rarely a concern.

HelloRoam eSIM vs UK roaming charges in Singapore
A clear comparison of data options for your Singapore stay.
RecommendedFrom £2.36 total
Plans start at £2.50. Buy before your flight, install via QR code at home, and land at Changi Airport already connected on StarHub. No daily UK carrier charges.
£3.73–£14.91 total
Singtel and StarHub tourist SIMs are available at Changi Airport. They are straightforward to buy but involve physical SIM-swapping. A HelloRoam eSIM is more convenient for modern dual SIM phones.
£7.46–£18.64/day
Singapore is a rest-of-world destination for UK carriers, so EE, Vodafone UK, and O2 charge daily international rates for data. Even a short stopover on daily charges adds noticeably to your bill. A HelloRoam eSIM gives you one fixed price instead.

Best time to visit Singapore from the UK
Singapore is warm and humid year-round at 25°C to 33°C. There is no traditional dry season, the island receives rain throughout the year, often as intense afternoon thunderstorms that pass quickly. February to April is generally the driest period. The wettest months are November to January during the northeast monsoon. Singapore's appeal lies in its food, culture, shopping, and architecture rather than weather, making it a viable destination at any time of year.
