Cheap data, fast 5G almost everywhere, and — good news — all your apps just work.
Getting online here is cheap and easy. A tourist SIM is about S$10–15 for more data than you can use, or buy an eSIM before you fly and land connected. Free Wireless@SG WiFi is at thousands of spots. Bring your passport to buy a SIM — that's the one rule to remember.
Most visitors want the first two. Free WiFi is a handy backup, not a whole-trip plan.
Buy online, install the code at home, land already connected. No shop, no queue. A little pricier per GB, and your phone must support eSIM.
From about S$10–15 for the whole trip. Counters in every arrival hall. Bring your passport — registration is required by law.
Free government WiFi at 5,000+ spots — malls, MRT, museums, hawkers. A great backup, but get a SIM for maps and rides on the street.
The cheapest plans already bury a normal trip in data. Pick by length, not by gigabytes.
| Option | From | Data | Calls |
|---|---|---|---|
| Singtel hi!Tourist | S$10 / 7 days | ~500GB | Unlimited local calls |
| StarHub Tourist | S$12 / 30 days | ~500GB (local + SE Asia) | Unlimited local calls |
| M1 Tourist | S$12 / 15 days | ~100GB | 500 local minutes |
| Airalo eSIM (data-only) | from ~S$15 / 3 days | unlimited* | No calls / SMS |
Approximate 2026 pricing from Singtel, StarHub, M1 and Airalo — plans change often, so check the provider before you buy. *"Unlimited" plans have a fair-use cap (roughly 100–150GB): effectively unlimited for a trip, not literally endless. All run on excellent nationwide 5G.
Singapore runs a free government WiFi network across the island — worth setting up as a backup.
Wireless@SG gives free internet at 5,000+ hotspots — shopping malls, MRT stations, libraries, museums, hawker centres, cafés and public buildings — with a guaranteed minimum speed. Since 2025, the newer Wireless@SGx logs your phone in automatically once you've set up a one-time profile, so there's no app to fuss with.
Logging in usually needs a working phone number to receive the code — a small chicken-and-egg on arrival. So grab a SIM or eSIM first, and treat free WiFi as the backup, not your only plan.
On open public WiFi, avoid banking or entering card details — use your mobile data for anything sensitive.
Yes. This is the opposite of home: Singapore has no Great Firewall. Your Chinese apps and the Western ones you can't normally reach both work on any local SIM — no VPN, no tricks. Use WeChat to message home and Google Maps to find your hotel, on the same phone, at the same time.
Singapore blocks only a tiny, symbolic list of sites (mostly adult content). For everyday travel, treat the internet here as fully open.
The only thing that trips visitors up — and it's a two-minute fix at the counter.
By law, every SIM you buy in Singapore (and a local telco eSIM) must be registered to your passport — so have the physical passport ready when you buy. The staff scan it, activate the SIM, and you're online in a couple of minutes.
A passport-registered tourist SIM stays active for 30 days. That's longer than almost any holiday, so it won't affect your trip — just don't expect the same SIM to work weeks after you leave.
Yes. By law, every SIM you buy in Singapore — and a local telco’s eSIM — must be registered to your passport when you buy or activate it, so have the physical passport in hand at the counter (about two minutes). A data-only travel eSIM bought online from an overseas provider may use its own sign-up checks instead.
Not much. Around S$10–15 buys a 7–30 day plan with roughly 100–500GB of data and, on most plans, unlimited local calls — far more data than a normal trip uses. Premium plans run to about S$30.
If your phone takes an eSIM, buying one online before you fly is the least hassle — you land already connected. A local physical SIM is usually a bit cheaper per GB and easy to grab at the airport. Either is fine; just check your phone is unlocked and eSIM-capable first.
Wireless@SG is genuinely useful — free government WiFi at 5,000+ hotspots (malls, MRT, libraries, museums, hawker centres), with a guaranteed minimum speed. It’s a fine backup, but coverage isn’t everywhere and logging in usually needs a phone number, so a SIM or eSIM is still worth having.
Yes, they all work normally on any local network, and no — you don’t need a VPN. Singapore has no Great Firewall, so your Chinese apps and Western apps (Google, WhatsApp, Instagram, YouTube) all work side by side. (Singapore blocks only a tiny list of sites, so treat the internet here as open.)
Telco and Changi Recommends counters are in every arrival hall (Terminals 1–4), and 7-Eleven and Cheers stores sell them too. eSIMs are best bought online in advance rather than at an airport counter.
Telco plans change constantly, so we keep the figures loose on purpose.
Move often — treat ours as "from about", and check the telco page before you buy.
Carry a fair-use cap (roughly 100–150GB) — effectively unlimited for a trip, not literally endless.
Often physical-SIM only at the desk — buy telco or Airalo eSIMs online in advance instead.
