How a Singapore eSIM compares
Carrier roaming
~€11/day
≈ €154 for 2 weeks
Typical international roaming charge from major EU/UK/US carriers in Singapore. Caps often activate after €60/month and throttle to dial-up speeds.
Local SIM at airport
€15 to €40
one-time plus setup hassle
Singtel and StarHub tourist SIMs cost €15 to €30 for a week at Changi airport kiosks. Activation needs a passport and takes 10 minutes, which is fine but eSIM is just easier.
RoamingFlex eSIM
€8.63
3GB / 15 days
Same plan covers 2 weeks of travel in Singapore. QR code in under 90 seconds. No app, no airport queue, no passport scan.
How much data you actually need in Singapore
Tourists in Singapore average 380MB/day. Singapore tourist data averages 350 to 420 MB per day. Grab is the default for taxis and food delivery, Google Maps handles the rest. Singapore is the easiest English-language country in Asia for tourists, so translation apps barely get used. Free Wi-Fi@SG is in most public spaces.

Insider tip
Singapore is one of the few countries where the public transit (MRT plus bus) is faster than Grab for most trips. The EZ-Link or SimplyGo contactless system works on any contactless bank card. Skip the souvenir EZ-Link cards.

Singapore eSIM frequently asked questions
Will the eSIM work on the Singapore MRT?
Yes, with full signal in stations and most tunnel sections. All three Singapore carriers have invested in tunnel coverage. 5G works in some sections too.
Does it cover the Changi Airport area for transit passengers?
Yes. The eSIM activates the moment your phone connects to a Singapore tower, which usually happens during landing or taxi at Changi. Useful for short layovers where Changi airport WiFi is the only alternative.
How much data do I need for a Singapore stopover or 3-day visit?
1GB to 3GB. Singapore is small (you can walk most of central Singapore in 30 minutes) and WiFi is everywhere, so data usage stays low.
Will Grab work on the Singapore eSIM?
Yes. Grab is the default ride-hailing app in Singapore and the eSIM supports all its features. Tap GrabCar, GrabTaxi, or GrabFood through the app and you're sorted.
Can I use the Singapore eSIM on a quick trip into Malaysia or Indonesia?
No. Singapore plans are Singapore-only. For cross-border trips (Johor Bahru day-trip, Batam ferry), you'd want a regional Asia plan.
Does the plan support tethering for laptop work?
Yes, every plan includes tethering. Singapore 5G speeds routinely hit 300+ Mbps download, which is fast enough for serious remote work.
