The nitty gritty
Singapore eSIM FAQs
That depends on your plan size, phone and budget, so rather than guess here, check out our in-depth guide on the best eSIM for Singapore, where we break it all down and compare providers properly.
Yes, though most travellers find it easier to buy their eSIM for Singapore online before they even leave home. You can compare plans and pricing properly, check genuine reviews before you commit, and message us directly on WhatsApp if you have any questions. It's also installed and ready to go on arrival, rather than something to sort out the moment you land, jet-lagged and juggling luggage.
You can, but buying online ahead of time gives you a few real advantages over an airport counter. You get to compare plans and pricing before you commit, read reviews from other travellers, and reach us directly on WhatsApp if you have any questions. Purchase your Singapore travel eSIM before you fly, install it while you're still on home WiFi, and it'll be sitting ready and waiting rather than something to queue up for once you've landed, jet-lagged and short on time.
Yes, a quick settings toggle. Once you've installed your eSIM for Singapore, you'll need to make sure data roaming is switched on for that specific eSIM line in your phone's settings (we'll walk you through exactly where to find it). It's a one-time step, and once it's on, your Singapore travel eSIM connects automatically without needing to touch it again for the rest of your trip.
Yes, completely. Installing a Singapore travel eSIM only adds a new data-only line alongside your existing SIM, thanks to dual SIM support on most modern phones. Your number, contacts, messages and chat history all stay exactly where they are, untouched, since the eSIM only handles mobile data in Singapore rather than replacing anything already on your phone.
Usually yes, and airport counters often carry a premium simply for the convenience of being right there when you land. An eSIM Singapore plan bought online ahead of time skips that markup entirely, plus you can compare pricing and check reviews before you buy rather than taking whatever's on offer at the counter. No queuing, no on-the-spot decision, and no risk of the kiosk being out of stock the moment you actually need it.
Yes, our Singapore travel eSIM includes an unlimited data option for 5, 15 or 30 days. Unlimited plans come with 3GB per day of high-speed data, which covers the vast majority of travellers without any issue. If you do go over that in a single day, your speed drops to 1Mbps rather than cutting out completely, so you're not left offline, just running slower until it resets at midnight. Need more time? You can easily extend or top up your Singapore eSIM through the ZenSim app.
These eSIMs don’t include voice minutes - data only. For any calling or texting, you’ll need to rely on VoIP or messaging apps such as WhatsApp, Viber, or Messenger.
Absolutely! You can install your Singapore travel eSIM up to 30 days before departure. Installing early means it will automatically activate once you land.
Rest assured, installing before you leave won’t start your data or count down your plan days until you arrive in Singapore.
If you see an activation error on iPhone when installing before arriving, you can ignore it-learn more in our eSIM Troubleshooting Guide.
Our Singapore travel eSIM is strictly for data; it doesn’t come with a phone number or traditional call/SMS service. You will need to use an internet based app for communication.
Your eSIM will activate automatically when you arrive in Singapore. Though we recommend installing your Singapore Travel eSIM before you arrive (this is different to activating).
To do this, scan the QR code we provide or install the eSIM directly from the ZenSim app while connected to WiFi. Once you arrive in Singapore, your eSIM will activate automatically.
If you encounter any issues check out our eSIM Troubleshooting Guide or contact us directly ☺️
The eSIM activates when you touch down in Singapore - if you’ve already installed it, it should connect automatically.
Installing while already in Singapore works too; it will start as soon as you complete setup.
If you experience connection issues, check our eSIM Troubleshooting Guide or reach out to our support team.
Good question! Opting for a travel eSIM instead of roaming in Singapore offers clear advantages:
Lower Costs: Say goodbye to outrageous roaming bills by switching to a local travel package designed for Singapore.
Seamless Switching: Change between data plans without fumbling with physical SIM cards - perfect for spontaneous travellers.
Budget Control: Track data usage in real time and avoid surprise charges or overages.
No, your plan only starts upon landing in Singapore. Installing beforehand ensures you’re ready to go as the activation will happen automatically.
You’ll need WiFi for installation, so do it before departure and this way you will be connected as soon as you arrive.
If you run into any issues, our eSIM Troubleshooting Guide can help, or contact us directly.
Yes - ZenSim’s eSIMs work in 200+ destinations, and Singapore is included. For travellers needing multiple-country access, we offer regional eSIMs. You can find those on our Travel eSIMs page.
Connectivity Troubleshooting: Check our troubleshooting guide if your eSIM won’t connect. Still stuck? Hit up our support team and we’ll get you back online fast.
eSIM Installation Help: For help setting up your eSIM, visit our installation guide, or simply contact us - we’re happy to assist.

Yep! 99% of our eSIMs can be topped up within the ZenSim app with just a couple of clicks. If you run out of data, need more days, or you even want to add a new destination to the same eSIM, you can do all of this in the top up section in the Zen Garden in the app.
Log into the app, navigate to the Zen Garden to find your Singapore service, and you will see a button to up your eSIM right there.
Top up plan options: Singapore top up plans are the same as the plans on the website except with a 10% discount!
Extending a long trip: If you're travelling to Singapore for more than 30 days, you can add as many top ups as you need to your first eSIM to extend the days and data you have. Each top up will only take effect when the previous eSIM is expired so you can purchase the top ups any time you want without worrying about overwriting your existing plan.
Multi country top ups: You can now add multiple countries to most of our eSIMs via top up, so if you're in Europe for example and are stopping over in Dubai on the way home, you can add a Dubai top up to your Europe eSIM so you don't need to reinstall anything. Alternate country top ups will only activate when you arrive in the new country.
Single-country eSIMs like the Singapore one are only valid within that country once activated.
For travel across borders, a regional plan might suit you better - our regional Travel eSIMs cover multiple countries in one.
You bet there is! Once you purchase an Singapore eSIM you will be able to access your unique referral URL which you can share with your travel buds.
If they click the URL and purchase a plan they will save A$5 on their order and you will receive a A$5 voucher on your account which will be automatically applied on your next purchase (provided they are a new customer of course).
You can track your referrals and access your referral URL in the ZenSim app. Check out our terms for more info.
Our Singapore unlimited plans include a 3GB daily allowance, which is more than enough for most people - average daily usage tends to sit under 1GB.
If you happen to use more than that in a day, your speed gets limited to 1Mbps until midnight, at which point your full-speed allowance kicks back in.
This only applies to unlimited plans - if you've chosen a fixed-data plan like 10GB or 20GB, there's no daily throttling at all, just use it freely until it runs out. We'll let you know before that happens, and you can top up in seconds via the ZenSim app.
It won't activate the moment you buy it - your Singapore eSIM won't touch your data or days until you actually arrive, so there's no downside to installing it in advance.
As long as it's installed beforehand, it'll activate itself the second you touch down, and that's the moment your plan officially begins.
As for running out - your eSIM expires once your data or days are gone, whichever comes first (just the days, if you're on unlimited). Buy a 30-day plan and it'll run out 30 days after arrival in Singapore, not 30 days after purchase.
Best way to find out is with our eSIM compatibility checker - just enter your phone details and it'll confirm whether it's compatible with our Singapore eSIM and networks.
Not 100% sure, or getting an unexpected result? Contact us and we'll help sort it out. Worst case scenario, if your phone truly isn't compatible, our refund policy gives you a full refund - so there's no risk in trying.
We sure do - it's covered under our 100% money back guarantee.
Cancelled trip, incompatible phone, or your travel plans just changing - all of these situations qualify.
Check out our refund policy for the full details, but the bottom line is: if you can't install or use the eSIM, you'll get every cent back.
eSIM options for other destinations
eSIM Singapore: Connected From Changi Onwards
A Singapore travel eSIM for every kind of trip
ZenSim's Singapore travel eSIM plans are designed for tourists, business travellers and anyone else passing through, not a one-size-fits-all plan stretched to cover every visitor type. Whether you're in town for back-to-back meetings, a long weekend of hawker centre hopping, or a stopover before heading further into Asia, there's a plan sized to match how you're actually travelling.
Instant QR code or one-tap install, no physical SIM required
Setting up your eSIM Singapore plan takes a few minutes from start to finish. Purchase online, then either scan your QR code or skip needing a second device with a one-tap install straight through the ZenSim app, on an eSIM-enabled iPhone or Android. Install it before you fly while you're still on home WiFi, and it auto-activates the moment you land, connecting you to mobile data in Singapore as a separate line alongside your existing SIM.
Keep your original number active with dual SIM support
Your eSIM for Singapore runs as a separate data-only line alongside your existing SIM, thanks to dual SIM support built into most modern phones. That means you keep your original number active for calls and texts exactly as normal, while your new eSIM quietly handles the data side of things in the background.
No roaming fees for the length of your stay
International roaming charges have a habit of turning a short trip into a surprisingly expensive one. A Singapore travel eSIM means no roaming fees at all, with an affordable prepaid plan sorted before you even board, so there's nothing unexpected waiting for you on your next phone bill.
Reliable coverage from Marina Bay to Sentosa
Singapore is a compact country, but your eSIM still needs to keep up as you move between very different pockets of it. Your ZenSim eSIM covers mobile data in Singapore across Marina Bay, Orchard Road, Sentosa, Changi Airport and the rest of the major tourist areas, so you're connected whether you're taking photos at Gardens by the Bay or navigating the queues at Universal Studios.
Unlimited data plans available, from 1GB to unlimited
Not every trip to Singapore calls for the same amount of data, so ZenSim's prepaid plans are priced to match different travel styles rather than pushing everyone toward the biggest option. Plans range from 1GB right up to unlimited data, across 5, 15 or 30 day options, so you can pick something sized for a quick business trip or a longer holiday. Need more once you're there? Topping up is just a couple of taps away in the ZenSim app. Comparing your options first? Our best eSIM for Singapore guide breaks down what to look for before you buy. Heading further afield afterwards? Our eSIM plans across Asia cover popular next stops like Malaysia, Thailand, Indonesia and Vietnam.
Top 3 Things to Do in Singapore
1. Wander Gardens by the Bay
Gardens by the Bay is the clearest example of Singapore's knack for blending nature with serious engineering, and it's usually the first thing that comes to mind when people picture the city's skyline. The Supertree Grove is the obvious starting point, a cluster of towering vertical gardens up to 50 metres tall, covered in real ferns, orchids and climbing plants that also double as solar collectors and rainwater channels for the wider park. After dark, the Supertrees put on a light and sound show that's worth timing your visit around, especially viewed from the elevated walkway strung between the tallest trees.
Inside the Flower Dome and Cloud Forest conservatories, the temperature drops noticeably as you step from Singapore's tropical heat into two very different climate-controlled worlds. The Flower Dome recreates a cool, dry Mediterranean-style environment packed with seasonal floral displays, while the Cloud Forest builds around a 35-metre indoor waterfall wrapped in mist and lush mountain vegetation, with a walkway spiralling up through the mist for views back down over the whole structure.
The wider gardens also connect directly to Marina Bay Sands and the waterfront promenade, making it easy to fold in a walk along the bay or a look at the Merlion statue on the same outing. Visit late afternoon if you can, so you catch the gardens in daylight before staying on for the evening light show as the sky darkens over the bay.
2. Escape to Sentosa Island
Sentosa sits just off Singapore's southern coast, connected to the mainland by a short cable car ride, monorail, or an easy walk across the boardwalk, and it packs an entire beach holiday's worth of activities into a single small island. Universal Studios Singapore is the headline attraction for a lot of visitors, with rides themed around Jurassic Park, Transformers and Minions packed into a compact, easy to navigate park that rarely takes a full day to get through.
Beyond the theme park, Sentosa's beaches along the southern coastline offer a properly relaxed contrast to the density of central Singapore, with beach clubs, water sports and beachfront bars strung along the sand. S.E.A. Aquarium is another popular stop, home to thousands of marine species including manta rays and sharks viewed through one of the largest viewing panels of its kind anywhere in the world.
As the sun goes down, Wings of Time is a nightly light, water and fireworks show performed right on the beach, and it's a genuinely good way to close out a day on the island without needing to plan much else. Sentosa is easy to treat as a half-day add-on or stretch into a full day depending on how many of its attractions you want to fit in.
3. Eat Your Way Through Singapore's Hawker Centres
Singapore's hawker centres are as central to the city's identity as any landmark, and they're one of the few places in the world where genuinely excellent, cheap food sits within a UNESCO-recognised cultural tradition. Maxwell Food Centre and Chinatown Complex are two of the most popular with visitors, packed with stalls serving Singapore's must-try dishes, from Hainanese chicken rice and chilli crab through to laksa, char kway teow and satay, often cooked by the same family for generations.
Tian Tian Hainanese Chicken Rice at Maxwell is one of the most famous stalls in the country, regularly drawing queues, though plenty of nearby stalls serve dishes just as good with a fraction of the wait. Lau Pa Sat, housed in a beautifully preserved Victorian-era cast iron building near the CBD, is worth a visit for the architecture alone, and transforms into a satay street each evening when the surrounding road closes to traffic and grills line up outside.
Eating at a hawker centre is also one of the best ways to see Singapore's mix of cultures play out on a single menu, with Chinese, Malay, Indian and Peranakan dishes often sitting stall by stall in the same complex. Go hungry, share plates across a few different stalls, and expect to pay only a few dollars a dish, even in the middle of one of the world's more expensive cities.
