Top 10 eSIM providers for Singapore in 2026
Airalo takes the top spot for Singapore eSIM coverage in 2026, largely because it partners with both Singtel and StarHub networks while keeping per-GB pricing under most competitors. The tiebreaker over Holafly — which offers unlimited data — comes down to Airalo's reliably strong speeds on the MRT underground sections between Orchard and Marina Bay.
Singapore's three mobile networks — Singtel, StarHub, and M1 — blanket the island so thoroughly that even the underground stretches of the Thomson-East Coast Line hold a signal. That makes raw coverage less of a differentiator here than in, say, rural Thailand. So the scoring leans heavier on per-GB price and activation friction. A provider that routes through Singtel's backbone tends to edge out slightly in indoor reception around the older shophouses of Kampong Glam and Tiong Bahru, where concrete walls are thicker than you'd expect. Price per gigabyte ranged from roughly S$1.20 to S$4.50 across the twelve providers we evaluated, and that spread matters when you're burning through data uploading photos from Gardens by the Bay or video-calling from a hawker centre in Chinatown. Hidden fees — particularly top-up surcharges and expiry traps on shorter plans — knocked several otherwise solid options down the rankings.
The mistake most visitors make is buying a physical SIM at Changi Airport's arrival hall when the queue is long and the jet lag is real. Those airport SIM counters at Terminal 1 and Terminal 3 charge a premium over what the same carrier sells digitally — and you're locked into whatever plan the sales rep pushes. The second trap is grabbing an unlimited plan without checking the fair-use throttle. Several providers advertise unlimited data for Singapore but quietly cap speeds to 128kbps after 1GB per day, which turns your Google Maps into a loading screen somewhere around Little India when you actually need directions. Worth noting: Singapore's strict telecom regulations mean most eSIM providers deliver what they promise on coverage. The differences show up in the fine print, not the signal bars.
To be fair, Airalo isn't the right pick for everyone. If you're staying longer than two weeks, Singtel's tourist eSIM works out cheaper on a per-day basis and gives you a local +65 number — handy for restaurant reservations along Tanjong Pagar or booking a slot at Marina Bay Sands. Heavy data users who plan to work remotely from co-working spaces in Holland Village might prefer Holafly's unlimited plan despite the higher per-GB effective cost, since there's no throttle anxiety. And if you're transiting through Changi for under 24 hours, the free airport Wi-Fi at Jewel honestly suffices.
The full list
-
Airalo
Partners with Singtel and StarHub for dual-network coverage across Singapore. Per-GB pricing sits around S$1.50, and the QR-code activation works before you even clear immigration at Changi. Reliable speeds on the MRT's underground segments through Orchard and Dhoby Ghaut.
-
Holafly
Unlimited data with no daily cap, routed through Singtel's network. Ideal if you're streaming from your hotel in Marina Bay or working remotely from a cafe in Tiong Bahru. Pricier per-day than Airalo but zero throttle worries.
-
Nomad eSIM
Competitive 5GB and 10GB plans on M1's network. Clean app with instant QR activation. Good indoor signal in the dense corridors of Bugis Junction and Orchard Gateway where some providers drop a bar or two.
-
Singtel Tourist eSIM
Singapore's largest carrier selling direct — no middleman markup. The local +65 number is useful for Grab rides and hawker centre reservations. Best value for stays beyond ten days, though activation takes a few more steps than app-based providers.
-
Ubigi
Built into many newer iPhones and Samsung devices, so activation is near-instant at Changi baggage claim. Uses StarHub's network. Pricing per GB runs slightly above Airalo but the convenience factor is real if you want data before reaching the taxi queue.
-
Maya Mobile
Regional Asia plans covering Singapore plus Malaysia and Indonesia — handy if you're planning a day trip to Johor Bahru or a weekend in Batam. Coverage on the North-South Line underground sections is solid. Per-GB price sits mid-range.
-
aloSIM
Budget-friendly option with plans starting under S$1.30 per GB. Routes through M1. The top-up process avoids the hidden surcharges that ding some competitors. Decent signal around Sentosa, which can be patchy with certain providers.
-
GigSky
Apple-integrated eSIM with one-tap setup from iPhone settings. Uses Singtel's backbone. Per-GB pricing is on the higher side — around S$3.80 — but the zero-friction activation appeals to travellers landing at Changi Terminal 4 who want coverage without fiddling with QR codes.
-
StarHub Tourist eSIM
Singapore's second-largest carrier with strong coverage in the western districts around Jurong East and Clementi where some resellers thin out. Direct purchase means no middleman, and a local number is included. Per-GB cost sits between Singtel and the budget app providers.
-
Yesim
Swiss-based provider with solid Singapore coverage on StarHub. Plans are a bit rigid — mostly 1GB, 3GB, 5GB tiers with no custom sizing. Signal holds well in the underground stretches of the Circle Line around Bayfront and Promenade stations.
