Our picks
Four plans, four different jobs
One top ranked plan and three answers to the questions travellers actually ask. A card marked "Editor's pick" was chosen by a person and carries their reasoning; "Top ranked" is simply the top of our published formula, which nobody chose. Every one is checkable against the table below in a click.

Coverage
Whose network you are actually on
An eSIM is a reseller agreement, not a network. These are the host operators the plans in Singapore attach to, counted across every plan we sampled.
Host operator data comes from the providers' own published coverage. Where a feed lists the same operators against every country in a multi-country bundle, we discard that attribution rather than credit a network it does not describe.
By provider
Which providers use which networks
How many of each provider's plans we sampled in Singapore, what they average per gigabyte, and which operators they ride.

Local knowledge
What to know about Singapore
Singapore requires SIM registration, which is the first thing to plan around. Some providers complete it on your behalf and some leave it to you; where it falls to you it means presenting identification, which is awkward to arrange on a short stopover. Check what a provider says about registration before buying rather than after.
Pricing is reasonable at a median of 1.02 USD per gigabyte from 1,415 plans across 10 providers, with the best at 0.24. A third advertise 5G and 91% permit hotspot.
The city is compact and wifi is close to universal, so the catalogue average of nearly 17 GB is far more than most visits need. Buy small.
Before you buy
How to choose
Match the allowance to the trip, not the price
The average plan sold here is 30.9 GB over 28 days. Buying the cheapest plan and topping up twice usually costs more than buying the right size once — check whether the plan supports top-up before relying on it.
Treat "unlimited" as a threshold
771 plans here are sold as unlimited. Almost all mean full speed up to a fair-use threshold and throttling after it. Compare those on price per day; a price per gigabyte for an unlimited plan is a number with no denominator.
Check the network, not the brand
44% of plans here advertise 5G, but the network belongs to a local host operator. The provider table below shows which operators each reseller actually rides — that is what decides coverage once you leave the city.
Know when the clock starts
Some plans start counting at purchase, some on install, some on first connection at the destination. A seven-day plan bought three days early is a four-day plan if it starts at purchase. Where a provider does not publish the trigger, we mark it unknown rather than guess.
Setup
How to install
Most phones released since 2019 do. Dial *#06# — if an EID number appears alongside the IMEI, the handset has an eSIM. A carrier-locked phone may still refuse a second profile.
Buy while you still have reliable internet. Whether to install immediately depends on when the plan's clock starts — check the activation trigger on the plan you chose.
The provider emails a QR code. On iOS: Settings → Mobile Service → Add eSIM. On Android: Settings → Network & internet → SIMs → Add. Keep the code; some providers let you reinstall with it, others do not.
This is the step people miss. A travel eSIM is technically roaming on a host network, so data roaming must be enabled for that line — and turned off for your home line, unless you want a bill.

How we rank this market
Collect
We read 6,781 live plans from 62 providers directly from their published catalogues, and normalise every allowance to integer megabytes and every price to integer minor units.
Separate
Unlimited and pay-per-GB plans are excluded from every median and percentile. A throttling threshold is not an allowance, and mixing the two makes a gigabyte look cheaper than it is.
Rank
The default order is a published formula: value percentile, feature completeness, data freshness, provider accuracy, coverage fit, first-party ratings and promo availability. Commission weight is zero, and no payout data reaches the ranking code at all.
Refresh
Prices are re-read continuously and this page was last recomputed on 12 October 2026. A sync whose numbers move implausibly is rejected rather than published.
Questions
Singapore eSIM questions
How much does an eSIM for Singapore cost?
Plans start at 0.28 USD. We track 6,781 plans from 62 providers, and the median works out at 1.86 USD per gigabyte once unlimited and fair-use plans are excluded from the calculation.
Which eSIM gives the best value in Singapore?
The lowest price per gigabyte currently available is 0.08 USD, against a market median of 1.86 USD. Sort the table by "Best value" to see the full ordering — that sort ignores our editorial ranking entirely and uses price per gigabyte alone.
How much data do I need for Singapore?
The average plan sold for this destination carries 30.9 GB over 28 days, which is what most travellers buy rather than what most travellers use. Maps, messaging and occasional browsing run well under 1 GB a week; video streaming is what moves you into the larger tiers.
Do eSIMs support 5G in Singapore?
44% of the plans we track advertise 5G here. Note what that figure is: it is the share of plans that *claim* 5G, not a coverage guarantee. The network you actually attach to belongs to a local host operator, not to the reseller, so real-world speed depends on their build-out in Singapore rather than on the plan you buy.
Can I use a personal hotspot with an eSIM in Singapore?
62% of plans here state that tethering is allowed. Where a provider does not say, we record it as unspecified rather than assuming yes — tethering is most often restricted on plans marketed as unlimited, which is exactly where people expect to be able to share a connection.
Do I need to show ID to buy an eSIM for Singapore?
Yes, frequently. Singapore is a market where registration rules mean many providers ask for a passport or ID upload before the eSIM will activate. Use the "No ID check" filter to see only plans that do not require it — arriving with an eSIM you cannot activate is a common and avoidable problem.
What does "unlimited" actually mean on these plans?
Almost always a fair-use threshold followed by throttling, not uncapped data. 771 plans here are marketed as unlimited. We show a price per gigabyte for those only where the provider publishes the full-speed threshold, and we exclude every unlimited plan from the median — a throttling threshold is not an allowance, and mixing the two distorts what a gigabyte appears to cost.
When does the validity period start?
It depends on the plan, and it is worth checking. Some start counting at purchase, some on installation, and some only when the eSIM first connects to a network at your destination. A seven-day plan bought three days before you fly is a four-day plan if it starts at purchase. Where a provider publishes the trigger we show it; where they do not, we mark it unknown rather than guessing.
