Singapore eSIM

100 Singapore plans · from $3.47

Singapore is compact, dense and almost entirely covered by high-speed mobile data — the practical question is not whether you will have signal but how quickly you can get connected after a long-haul flight. An eSIM activates the moment you land at Changi, with no counter and no registration.

Landing at Changi (SIN)

Changi has excellent free Wi-Fi, but it needs a passport-scan kiosk or SMS code to log in. An eSIM already installed means you are online before you even reach immigration.

Which networks you'll be on in Singapore

Siima eSIMs for Singapore ride Singtel and StarHub. Both deliver island-wide 5G; Singtel edges ahead marginally on indoor coverage in older HDB estates.

Coverage around Singapore

MRT network

Full coverage in every tunnel and station across the entire MRT. Singapore has had continuous underground mobile service for well over a decade.

Marina Bay and the CBD

Dense 5G with very high speeds. Gardens by the Bay, the Marina Bay Sands promenade and the whole financial district are consistently strong.

Sentosa and the southern islands

Sentosa is fully covered including the cable car and the beaches. The smaller southern islands and Pulau Ubin have workable but thinner 4G.

Nature reserves

MacRitchie, the Southern Ridges and the Botanic Gardens all hold signal on the trails. The interior of the Central Catchment reserve is the one place it noticeably weakens.

How much data you need

Singapore trips are usually short: 1–3 GB covers a typical two-to-four day stay. If you are on a long layover only, the smallest plan is plenty.

Frequently asked questions

Is an eSIM worth it for a Singapore layover?
If your layover is long enough to leave the airport, yes — a small plan costs little and Changi's free Wi-Fi does not follow you into the city. For a short layover spent inside the terminal, the airport Wi-Fi is genuinely good enough.
Does a Singapore eSIM work in Malaysia or Indonesia?
No. A Singapore plan covers Singapore only. If you are crossing to Johor Bahru or hopping to Batam or Bintan, look at an Asia regional plan that covers all three countries on one eSIM.
How do I set up an eSIM before arriving in Singapore?
Install it at home while you still have Wi-Fi: open Settings → Cellular → Add eSIM and scan the QR code from your Siima confirmation email. Leave the line switched off until you land — the plan starts counting from first use in Singapore, not from purchase.
How much data do I need for a trip to Singapore?
Singapore trips are usually short: 1–3 GB covers a typical two-to-four day stay. If you are on a long layover only, the smallest plan is plenty.
Is an eSIM cheaper than roaming in Singapore?
Almost always. Daily roaming passes from most home carriers run $10–15 per day, while Siima plans covering Singapore start from $3.47 for the whole trip. You also avoid per-megabyte charges if you exceed a roaming pass allowance.
