991 of these 1684 plans were checked against the seller's own shop on 17 October 2026. The rest come from the seller's own feed or plan pages and are not yet independently checked.
The Watchdog Pick is chosen automatically: the lowest real price per GB of the 1684 plans in this view. Bulk data pools above 50 GB cannot win it, because their per GB rate only exists if you use data no traveller uses. Providers cannot pay for it, and a commission never changes the ranking. Prices are shown in USD and can change at checkout.
Price per GB counts only data you can use inside the validity, at most 3 GB a day, so a big pool on a short validity cannot buy the top spot. Every provider's best two plans come first, then the rest. A plan marked Unverified price undercuts every other provider here by more than half and waits at the end until we have checked it on the seller's site. How we rank
Unlimited rows show the daily amount at full speed. Some rows also show the speed after that amount. A row with no speed does not mean the plan stays fast, so check the plan on the seller's site.
Some links here earn us a commission. It never changes the order. How we make money The row marked Sponsored is a paid placement shown above the ranking, not part of it. Advertise here.

Cheapest eSIM for Singapore: the numbers
As of 17 October 2026, 06:01 GMT, the cheapest eSIM for Singapore is ASIMGO with 50 GB for 20 Days at $16.52. That is $0.33 per GB, the best rate of the 1684 plans we compare from 59 providers. 905 plans include 5G. 627 support top ups. That timestamp is the exact moment of our latest price check, and the table above always shows the live order.
Which is the best eSIM for Singapore?
There is no single best eSIM for Singapore, because the right plan depends on how long you stay and how much data you use. What we can do is rank the 1684 plans on the numbers, as they stand on 17 October 2026:
- Best value overall ASIMGO, 50 GB for 20 Days at $16.52. That is $0.33 per GB, the lowest real rate of every Singapore plan we track.
- Best for a short trip Superalink, 1 GB for 1 Day at $0.75. The cheapest ticket that still gives you at least 1 GB for a week or less.
- Best for a long stay Yatelo, 50 GB for 30 Days at $17.98, $0.36 per GB. The best rate among plans that last 30 days or more.
- Highest daily cap on an unlimited plan SimSmash, 1 Day at $10.49, full speed up to 10 GB a day. Set that daily cap against the fixed plan above before you pay for the word unlimited.
None of these picks is chosen by a person. Each one is the first row of a sort on live prices, so it changes whenever a provider moves a price, and ASIMGO did not pay to be named here.
Which mobile networks does Singapore have?
Singapore was the first country in the world fully covered by standalone 5G. Singtel alone covers more than 99% of the population with 4G and 95% with 5G standalone.
- Singtel: Singtel is the clear leader with about 47% of the mobile market and the highest 5G standalone population coverage of any Singapore operator at over 95%.
- StarHub: StarHub is a long established rival and claimed over 99% 5G coverage of Singapore back in early 2024.
- M1: M1 is one of the three legacy operators and sells popular tourist SIMs with big data bundles.
- Simba: Simba is the newest network, and its entry alongside the MVNOs pushed Singapore's data prices to among the lowest in Southeast Asia.
More than ten MVNOs like Circles.Life compete here, which keeps local prepaid data very cheap, though every SIM still needs passport registration.
The eSIM plans we compare on this page connect to:
The list above is Singapore's operator market. The badges are the networks our tracked plans actually roam onto, which can be a subset of it, and the same network is sometimes sold to roaming partners under a different brand name. So a guide praising an operator you do not see badged here is describing a local SIM, not the travel eSIMs compared above.
Is 5G available in Singapore?
All the main operators run nationwide 5G. Singtel's standalone network covers over 1,700 outdoor and 1,000 indoor locations, including all shopping malls, transport hubs and all six underground MRT lines.
How much data do you need in Singapore?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in Singapore right now:
Are unlimited eSIMs for Singapore really unlimited?
Not always. 649 of the 1684 plans above are sold as unlimited, and most of them carry a daily fair use cap. A further 35 plans are unlimited in a different way: one capped speed for the whole plan, shown next to the word Unlimited in the table. For Singapore the caps we can see published are 0.5 to 10 GB a day: past that the speed drops, often to 1 Mbps or less, until the clock resets. That is fine for messages and maps, slow for video. At $0.33 per GB from ASIMGO, a fixed plan often works out cheaper than unlimited unless you genuinely burn several GB a day. That is why we rank by price per GB and not by the word on the label.
Here is what each seller on this page actually allows per day before it slows you down. No seller publishes this next to its rivals, which is exactly why it is worth showing.
Every seller that publishes a daily allowance is listed on our daily data caps page, with the cheapest plan at each one. The gap between the top and bottom of that table is the whole point. Two plans both sold as unlimited can differ several times over in what you actually get at full speed, and the cheaper one is not always the smaller allowance.
eSIM or a local SIM card at the airport in Singapore?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter for a tourist SIM card. Data for Singapore starts at $0.26 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your Singapore eSIM
Pick the plan, not the brandThe cheapest rate in Singapore today is $0.33 per GB from ASIMGO, against a median of $1.30. The QR code arrives by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Installation needs a connection, and the one thing you will not have when you land in Singapore is a working connection.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to attach to M1, SingTel, Singapore, Singtel, StarHub, Starhub, TPG Telecom. Expect 5G where the network reaches, 4G everywhere else.
Know what happens when it runs out627 of the 1684 plans here can be topped up, so running out is not the end of the trip. If you would rather over buy than top up, the cheapest plan with at least 5 GB is ASIMGO at $2.59.
Good to know before you land in Singapore
IMDA requires every prepaid SIM or eSIM to be registered against a valid passport at purchase or activation. A SIM registered on a passport stays valid for only 30 days unless you update it with a local NRIC or FIN.
Tourist SIMs from the main operators start around S$10 to 12 at city rates, but expect to pay more at Changi counters, roughly $25 US and up. You must show your passport at purchase.
Signal is strong everywhere including underground MRT lines, so any network works fine for a short trip. If you want cheap local data, the M1 and Singtel tourist SIMs give 100GB for around S$12 to 30.
Singapore Travel eSIM FAQ
Everything you need to know about using an eSIM in Singapore
What is the cheapest eSIM for Singapore?
Right now the cheapest option ranked by price per GB is ASIMGO with 50 GB for 20 Days at $16.52. That works out to $0.33 per GB. Prices change often, so the table above is re-sorted at every price check.
Which is the best eSIM for Singapore?
It depends on the trip, so we rank rather than pick a favourite. On today's prices the best value for Singapore is ASIMGO at $0.33 per GB, the lowest real rate of the 1684 plans we compare. For heavy daily use there are 649 unlimited plans, most with a daily fair use cap, and they only win if you genuinely burn several GB a day. Every pick on this page is the first row of a sort on live prices. No provider can pay to be named best.
Is eSIM available in Singapore?
Yes. We track 1684 prepaid travel eSIM plans from 59 providers that work in Singapore, roaming onto M1, SingTel, Singapore, Singtel, StarHub, Starhub, TPG Telecom. You need a phone that supports eSIM and is not locked to a carrier; most iPhones from the XS onward and most flagship Android phones from 2019 on qualify.
Which networks will my eSIM connect to in Singapore?
The plans we compare connect to M1, SingTel, Singapore, Singtel, StarHub, Starhub, TPG Telecom. The exact network depends on the plan you pick. Check the plan details before you buy if one network matters to you.
Do Singapore eSIMs support 5G?
905 of the 1684 plans we track for Singapore include 5G where the local network offers it. The rest run on 4G, which is still fine for maps, calls over apps, and video.
Can I buy a Singapore eSIM online before I travel?
Yes, and you should. Every plan on this page is sold online and delivered by email as a QR code within minutes. Install it on wifi at home, leave the line switched off, and turn on data roaming for it when you land in Singapore. The validity clock on most plans only starts when the eSIM first connects.
Can I top up my Singapore eSIM if I run out?
Yes. 627 of the 1684 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Is an eSIM cheaper than a local SIM card in Singapore?
For a trip of days or weeks, usually yes. Data for Singapore starts at $0.26 for 100 MB on this page, with no queue, no shop and no passport handed over at a counter. A local SIM card can still win if you stay for months or need a local phone number.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
Does a Singapore eSIM work on iPhone and Android?
Yes, on any carrier unlocked phone with eSIM support: iPhone XS or newer, Google Pixel 3 or newer, Samsung Galaxy S20 or newer and most recent flagships. The plans are identical on both; only the install steps differ, and both take about a minute on wifi.
How many GB do I need for a week in Singapore?
Around 3 to 5 GB covers a week of maps, messaging, and normal browsing. Heavy video or hotspot use needs 1 to 2 GB per day. Today the cheapest plan with at least 5 GB is ASIMGO at $2.59.
Which Singapore eSIM gives the most data per day?
Of the plans sold as unlimited here, SimSmash allows the most at full speed, 10 GB a day from $10.49. The smallest allowance on this page is 500 MB a day, from 8 sellers. Every one of them is advertised as unlimited, and past the daily allowance the speed drops, often to 1 Mbps or less, until the next day. Check the allowance, not the word.
