Singaporechecked Aug 2026StraightforwardStaying connected in Singapore.
Singapore is small, almost entirely covered and full of free wifi. That combination produces an answer we do not often get to give: on a short stop you may not need to buy anything at all.
At a glance
Coverage
Superb, the whole island
Carrier roaming
$10 to $12 a day
Cheapest
Often nothing, on wifi
Local SIM
About $15 for 100GB or more
Coverage is superb across the whole island, the MRT included, so there is nothing to plan around. On a short stopover, between hotel wifi, mall and cafe wifi and the public Wireless@SG network, a lot of travelers get through Singapore without buying data at all, and that is a real answer rather than a fallback. If you want a connection that follows you into a taxi queue, a local prepaid SIM from Singtel or StarHub is unusually good value, roughly 15 to 25 dollars for 100GB or more, bought with your passport at the airport or any 7-Eleven. A Nomad eSIM is a few dollars per gigabyte and earns its place if you want data working before you land or you are continuing through the region. Your US carrier's day pass is about 10 to 12 dollars a day (AT&T and Verizon), and T-Mobile may already include a high-speed allowance abroad, from 5GB up to 30GB by plan. Never roam pay-per-use, at about 2 dollars a megabyte.
On a short stop, wifi may be the whole answer
Singapore is roughly the size of a large city and it is wired accordingly. Hotels, malls, hawker centers, cafes, Changi itself and the public Wireless@SG network mean that on a two or three day stop you can plan the day over breakfast wifi, ride the MRT on downloaded directions and pick the signal back up at the next stop. Plenty of stopover travelers do exactly that and never buy a data plan.
This page sells eSIMs, so it is worth saying plainly that a short Singapore stop is one of the places where the honest answer is to buy nothing. The case for buying data is not the island being hard to navigate, it is wanting a connection that is with you continuously, in a taxi queue or a Grab or a hawker center at 11pm, without hunting a sign-in page. If that is worth a few dollars to you, buy it. If it is not, you are fine.
If you do want data, the local SIM is remarkable value
A local tourist SIM from Singtel or StarHub runs about 15 to 25 dollars and carries 100GB or more, which no visitor is going to exhaust. You need your passport at purchase, registration is done at the counter and it works immediately. On a per-gigabyte basis nothing else here comes close, so if you are staying a week or working from a laptop, this is the cheap answer.
A Nomad eSIM is the better fit for two specific situations: you want to land already connected, or Singapore is one leg of a regional trip and a plan covering several countries is simpler than a SIM per border. It is a few dollars per gigabyte. For a single long Singapore stay, the local SIM wins on price and it is not close.
Coverage, and the one cost worth watching
This section is short because there is nothing to warn you about. Coverage is strong island-wide, underground on the MRT included, 5G is widespread, and there is no gap worth planning around. The only real money risk is roaming with no plan at all: pay-per-use is about 2 dollars a megabyte and phones use data in the background, so turn off data roaming until an eSIM, a local SIM or a day pass is active.
If you do roam, AT&T and Verizon day passes are about 10 to 12 dollars a day, and T-Mobile's current mid and upper tiers include roughly 5GB on Experience More, Magenta MAX and Go5G Plus, 15GB on Experience Beyond and Go5G Next and 30GB on Better Value, slowing to 256kbps after that. This guide is written for US travelers departing the US. For more, see cash or card in Singapore and the Singapore money guide.
Common questions
Quick answers.
Do I need an eSIM for Singapore?
On a short stopover, quite possibly not. Hotel, mall and cafe wifi plus the public Wireless@SG network cover a two or three day stop for most people. Buy data if you want a connection with you continuously rather than because the island is hard to navigate without one.
How much is a SIM card in Singapore?
A Singtel or StarHub tourist SIM is roughly 15 to 25 dollars and carries 100GB or more, which is far more than a visitor will use. You need your passport at purchase, and they are sold at Changi and in convenience stores across the island.
Is there free wifi in Singapore?
Yes, widely. Hotels, malls, hawker centers, cafes and Changi all have it, and the public Wireless@SG network covers many public spaces. It is good enough that a short stopover can reasonably run on wifi alone.
How much does it cost to use my US phone in Singapore?
About 10 to 12 dollars a day on an AT&T or Verizon day pass. AT&T caps its Day Pass at 10 daily fees per line per bill period, so about 120 dollars covers the rest of that bill period on land, while Verizon's TravelPass has no equivalent cap and keeps billing daily, which matters on a trip longer than 10 days. T-Mobile is worth checking first, since its mid and upper tiers include 5GB to 30GB of high-speed data abroad before slowing to 256kbps. Never roam with no plan, since pay-per-use runs about 2 dollars a megabyte.
More on Singapore
The little money things nobody warns you about.
- Taxis in Singapore, and the Grab appSingapore taxis are metered, honest and strictly regulated, and Grab makes booking effortless. The only thing to understand is the list of legitimate surcharges, not scams. Here is how it works.
- Tipping in SingaporeSingapore is not a tipping country. Most restaurants add a 10% service charge, shown as the ++, so a tip is already built in. At hawker centres and for taxis, no tip is expected. Here is what you actually owe.
- Do I need cash in Singapore, or can I use cards?Short answer: a card for almost everything, a little cash for hawker stalls. Singapore is very card-friendly, and even many hawker centres now take cashless. Here is how to handle it.
- Bringing your dog or cat to Singapore.Singapore is unusual among rabies-free destinations. Unlike Australia, New Zealand, or Japan, the US now sits in Singapore's middle tier, which means no quarantine by default. The process is more about paperwork choreography than a long wait: licences filed on time, a rabies titer with strict timing, and, since April 2026, an approved pet agent to clear your pet on arrival. Two specific situations still trigger a 10-day home quarantine, so the whole game is avoiding those. Here is the route.
- What does getting sick in Singapore cost a visitor?Singapore has some of the best hospitals in Asia and one of the clearest positions on who pays for them. Citizens are heavily subsidised. Visitors are not subsidised at all, and the difference is the entire story.

Our own readChecked Aug 2026. The uncomfortable part of this page is that its honest recommendation for the most common Singapore trip, a stopover of a night or three, is to buy nothing, and we earn a commission on eSIMs. We have written it that way because the alternative is telling a reader to spend money on a problem the island does not have. Local SIM pricing is a current read and the allowances are generous enough that the exact figure rarely changes the decision. Carrier day-pass figures are an Aug 2026 snapshot and move faster than anything else here.
