Is it worth getting an eSIM for Singapore?
For most visitors, yes. An eSIM is the easiest way to stay online in Singapore, installed before you fly and connected the moment you land at Changi, with no shops or paperwork.
Roaming on your home plan is usually expensive, often around $10 a day. A local Singapore SIM is cheaper but means a shop visit and passport registration. An eSIM avoids both, with data from $3 with Ubigi, or unlimited data from $11.90 for 3 days with Holafly, all on Singapore's fast 5G networks.
Whether Singapore is your whole trip or a stopover on the way through Asia, an eSIM is the smarter, simpler way to stay connected.
What is an eSIM?
An eSIM is a digital SIM card built into your phone that lets you activate a mobile plan without a physical card. You can install it before your flight by scanning a QR code or using a provider app, and your connection starts the moment you land.
Unlike a traditional SIM, there is nothing to swap or lose. Your data plan is stored directly on your device. Most recent phones support eSIMs, including any iPhone from XR and newer, Google Pixel 4 and later, and many Samsung and Xiaomi models.
In Singapore, eSIMs connect to the city-state's mobile networks and deliver some of the fastest 5G speeds in the world, a simple, reliable way to stay online without visiting a store.
Is eSIM available in Singapore?
Yes. Singapore fully supports eSIM technology for travellers. You can install an eSIM from international providers like Ubigi and Holafly before you arrive, and your phone connects automatically to a partner network when you land. Singapore's main carriers, Singtel, StarHub, and M1, run world-leading 4G and 5G networks with near-total coverage.
As long as your phone is unlocked and eSIM-compatible, you can install your plan before your flight and activate it the moment you reach Changi Airport.
Is an eSIM or a local SIM card better for Singapore?
An eSIM is usually better for Singapore because it is faster to set up and works the moment you arrive. You can install it before your flight and skip the store visit and passport registration that a local SIM requires.
A local Singapore SIM can suit very long stays, but for a short trip or stopover the convenience of an eSIM almost always wins. For most visitors, an eSIM is simpler, faster, and online before you leave the airport.
Both of our recommended providers, Ubigi and Holafly, connect to Singapore's major networks, giving you reliable data without the hassle of a local SIM.
Mobile networks in Singapore: which one matters for your trip?
Singapore is served by three main mobile networks, and coverage is excellent island-wide on all of them, so the differences are smaller here than in larger countries.
Singtel has the widest and fastest network in Singapore, with outstanding 5G across the island and the strongest reach in buildings and on the MRT.
StarHub offers fast, reliable coverage across the city, competitive on speed in the central and residential areas.
M1 provides solid, fast coverage across Singapore, with good performance in the main districts.
Which network matters for your eSIM choice
- Wherever you go in Singapore, from Marina Bay to Sentosa, every network delivers excellent connectivity.
- Coverage is strong even underground on the MRT and inside malls and hotels.
- For the very fastest 5G speeds, Singtel has a slight edge.
Both Ubigi and Holafly connect to Singapore's leading networks, and Holafly runs specifically on Singtel and StarHub, the island's two strongest. Because coverage is excellent nationwide here, network choice matters far less in Singapore than in a larger country, so you get excellent data whichever you pick. You can check current plans on the Ubigi and Holafly sites.
Best eSIMs for Singapore in 2026
The best eSIM for Singapore depends on how you travel and how much data you need. Below are our two recommended providers, Ubigi and Holafly, both offering reliable coverage across Singapore, flexible plans, and quick online activation.
Ubigi: Best for reliable speeds and flexible plans
Ubigi is a great option if you value fast, stable data and clear pricing. It connects to Singapore's top networks and offers blazing 5G across the island, with plans to match any trip length and real-time usage tracking in the app.
Why Ubigi is good for Singapore:
- Flexible plans from 1GB up to unlimited data
- Plans activate as soon as you land at Changi
- Reliable data connection for work and travel
- Real-time usage tracking and easy top-ups in the app
- Supports tethering for laptops and tablets
- Discount code NOMADWISE for 10% off your first purchase
Ubigi pricing for Singapore
Plans start from $3 for 1GB, with 10GB for $14 on a 30-day plan and an unlimited 7-day plan at $19. You can top up or switch plans anytime. The full price list is in the summary table near the top of this guide.
Holafly: Best for unlimited data on a short trip
Holafly works differently to most eSIM providers. Instead of selling gigabytes, it sells days of unlimited data, and it covers the short durations Ubigi does not offer. For a Singapore stopover or a long weekend, that means you buy exactly the days you are there and never think about data again.
Why Holafly is good for Singapore:
- Unlimited data on every plan, with no gigabyte allowance to track
- Short 3, 5, 10 and 15 day options that suit stopovers and long weekends
- Runs on Singtel and StarHub, Singapore's two strongest networks
- Always On: 1GB of backup data every month, included at no cost
- Instant QR-code activation before you fly
- 24/7 chat support in several languages
- Works with dual SIM, so you can keep your home number active
- Discount code NOMADWISE for 5% off
Holafly pricing for Singapore
Plans start from $11.90 for 3 days of unlimited data, with 7 days at $27.50 and 30 days at $73.90. The full price list is in the summary table above.
Two things worth knowing before you buy. If your trip matches Ubigi's 7 or 30 day unlimited plans, Ubigi is cheaper at both, so Holafly's real advantage is the 3, 5, 10 and 15 day durations Ubigi does not sell. And while the data itself is unlimited, hotspot sharing is capped at 1GB per day, so it is not the pick if you plan to tether a laptop all day.
Both providers are reliable choices for Singapore, easy to install, and designed for travellers. The right pick mainly depends on whether you prefer Ubigi's cheap data and flexible plans or Holafly's unlimited data by the day.

Unlimited data eSIMs for Singapore: what are your options?
If you would rather not count gigabytes, both of our picks sell unlimited plans for Singapore, but they suit different trip lengths.
Ubigi sells unlimited data on 7 and 30 day plans, at $19 and $49. If your trip matches either window, Ubigi is clearly cheaper: $19 against $27.50 for a week, and $49 against $73.90 for a month.
Holafly sells unlimited data by the day, from 3 days up to 30, at $11.90 to $73.90. It fills the gaps Ubigi leaves, so a 3 day stopover does not mean paying for a full week of data you will not use.
A simple way to choose: if you are in Singapore for about a week or about a month, take Ubigi. If you are there for three days, five days, or a fortnight, Holafly has a plan that fits and you will not pay for days you are not using. And if your data needs are light, remember Ubigi's fixed bundles start at just $3 for 1GB, which is plenty for maps and messaging on a short stay.
Customer support and ease of use
Good support helps when you are getting set up in a new place. Ubigi manages everything through its app, with real-time usage tracking, easy top-ups, and a help centre for setup questions. Holafly runs 24/7 chat support in several languages, and offers a refund window of up to six months if your plans change. Both install in just a few minutes, from purchase to connection.
eSIM coverage across Singapore
Singapore has some of the best mobile coverage in the world, with fast 5G island-wide. Both Ubigi and Holafly perform excellently in the areas below.
Changi Airport and arrival
Coverage is instant and fast the moment you land, so your eSIM activates before you even reach the taxi queue.
Marina Bay, the CBD and Orchard Road
The downtown core and shopping districts have outstanding 5G, a dependable base for remote work, video calls, and navigation.
Sentosa and the south
The resort island and southern attractions have strong, fast coverage across the beaches and theme parks.
The MRT and the heartlands
Coverage stays strong underground on the MRT and across residential neighbourhoods like Tampines, Jurong, and Woodlands.
How to choose the right eSIM for Singapore
Choosing the right eSIM for Singapore depends on how you travel and how you use your data. Start by checking that your phone supports eSIMs, then look at plans based on data, duration, and support.
Here is what to consider before buying your Singapore eSIM:
- Phone compatibility: Most iPhones from XR and newer, Google Pixel 4 and later, and many Samsung and Xiaomi models support eSIMs.
- Data usage: Light users can stay connected with a few GB from Ubigi for a couple of dollars, while heavy users may prefer an unlimited plan from either provider.
- Trip length: Ubigi's unlimited plans suit trips of about a week or a month, while Holafly covers the 3, 5, 10 and 15 day durations in between.
- Stopover or wider trip: If Singapore is one stop on a bigger Asia trip, consider a regional plan that covers multiple countries.
- Hotspot needs: If you plan to tether a laptop for long stretches, check the limits. Holafly caps hotspot sharing at 1GB per day, while Ubigi's allowance is drawn from your plan data.
How to set up your eSIM in Singapore
Setting up an eSIM in Singapore is quick and can be done entirely online. You can install it before your flight and activate the plan as soon as you arrive.
Step by step eSIM setup guide:
- Check compatibility: Make sure your phone supports eSIMs and is unlocked. Most recent iPhones, Google Pixel, and Samsung models are compatible.
- Choose a provider: Pick a trusted option that fits your data needs, such as Ubigi or Holafly.
- Buy your plan: Select your data package or duration online and complete the purchase.
- Install your eSIM: You will receive a QR code or app link. Scan it or follow the in-app setup instructions.
- Activate your plan: Turn on mobile data and select the new eSIM as your active plan once you land in Singapore.
- Test your connection: Open a browser or map app to confirm you are online before leaving Changi.
Most travellers complete the process in under five minutes. If anything goes wrong, both Ubigi and Holafly offer support to help you get connected.

Staying connected is just one part of a smooth trip. If you are on a longer journey through Asia, make sure you are covered with reliable travel insurance too. See our guide to the best travel insurance for digital nomads for coverage details.
Final recommendation: which eSIM is best for Singapore?
Both Ubigi and Holafly are reliable choices for staying connected across Singapore. The best option depends on your travel style and data needs.
Choose Ubigi if you want cheap data, flexible plans, and the best value on unlimited if your trip runs about a week or a month. It is ideal for digital nomads and remote workers who need steady data for calls, meetings, and navigation. Use code NOMADWISE for 10% off your first purchase.
Go for Holafly if you want unlimited data without tracking an allowance, especially on a stopover or short stay. Its 3, 5, 10 and 15 day plans cover the trip lengths Ubigi does not sell, it runs on Singtel and StarHub, and 24/7 chat support is there if you need it. Use code NOMADWISE for 5% off.
If you are still unsure, both options work reliably across Singapore, so you can be confident with either.
