Singapore eSIM
100 Singapore plans · from $3.63
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.

How “Unlimited” works: Never cut off — each plan gives a set amount of full-speed data, then a slower speed. The exact allowance and speed are shown on every plan.Read more
Unlimited plans never run out and your eSIM is never disconnected, but every one has a fair-use limit: a set amount of full-speed data, after which the speed is reduced. The amounts differ between plans — most give a daily full-speed allowance that refills every 24 hours from when you first activate the eSIM, while Premium plans give a larger allowance for the whole plan instead. Each plan states its own allowance and the speed after it before you buy. At the reduced speed, messaging, maps, email and light browsing still work; video streaming and video calls may not. If you want every gigabyte at full speed, choose a fixed-GB plan.
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.
