How to Buy and Activate an eSIM in Singapore: A Traveler’s Complete Guide

Travelling to Singapore soon? You’re not alone. In 2024, Jewel Changi Airport welcomed over 80 million people, marking its highest footfall ever. And it’s not just a seasonal spike. Singapore recorded 3.29 million visitors in July and August alone, a nearly 5% year-on-year increase.

With this growing influx, more travellers are now skipping the SIM card queues and choosing an eSIM for travel. It activates before you land, saves you time, and keeps you connected instantly.

In this guide, you’ll discover how to get an eSIM for Singapore, activate it, choose the right plan, and avoid common tourist mistakes.

What is eSIM Singapore?

If you’re new to it, here’s what an eSIM is: it’s a digital SIM built into your phone. You don’t need to insert anything or open the SIM tray.

It’s already active inside your device. You just scan a QR code, and the plan loads within seconds.

In simple words, an eSIM in Singapore lets you connect to a local mobile network without visiting a shop, showing your passport, or filling forms. Everything happens online before your flight or right after landing. This makes it ideal for tourists, students, and anyone who doesn’t want the typical SIM card stress.

No waiting. No paperwork. Just the internet, instantly.

eSIM vs physical SIM: key differences

A physical SIM is the tiny plastic chip you insert into your phone. To get one, you usually visit a shop, show your passport, wait in line, and then fumble with a SIM tray tool to swap it in. Sounds familiar?

With an eSIM for Singapore, you don’t go anywhere. It’s already inside your phone. You buy a plan online, scan a QR code, and the network connects in seconds with no plastic, no waiting.

Also, with an eSIM, you don’t need to remove your primary SIM. That means you can keep your home number active for bank OTPs while using your Singapore eSIM for data.

Why eSIM is popular in Singapore

Singapore moves fast, and so do its travellers. Most people don’t want to waste time at airport kiosks or deal with physical SIMs. That’s where eSIMs win.

They’re easy to set up, support top local networks like Singtel, StarHub, and M1, and work instantly the moment your flight lands. You don’t even need to visit a store.

What’s more, Singapore eSIM activation happens in minutes. Just scan the QR code, and your data starts working, no ID checks or passport scans required.

This is why tourists, students, and digital nomads are switching to eSIMs. They get the same network coverage, minus the hassle.

Benefits of Using eSIM in Singapore

The biggest reason people go for an eSIM while in Singapore is convenience. You don’t have to hunt for a SIM shop or open the tiny tray on your phone. The setup takes just a minute even before you fly.

It’s also great if you want to keep your home number active. Your physical SIM stays where it is. The eSIM handles your internet. So you won’t miss OTPs or calls from back home.

You also get flexible plans. Whether it’s a 3-day city trip or a month-long work stay, there’s a prepaid plan for every kind of traveller. No paperwork. No roaming bills. Just fast data from the moment your flight lands.

Plus, Singapore’s mobile networks are strong. Whether you’re in the MRT, at Marina Bay, or grabbing kopi at a hawker centre you’ll stay connected.

Instant setup and flexible plans

You don’t need to visit a shop, show your passport, or wait for hours. With eSIM, everything happens online. Once you buy a plan, you scan the QR code.

Most providers offer multiple options. Whether you’re staying for 5 days or 3 weeks, you’ll find something that fits your data needs and budget. It’s one of the best eSIM Singapore plans and features  flexibility.

If your usage increases, you can top up in a few taps. No need to buy a new SIM.

Dual profiles for work and travel

Many travellers need to stay reachable back home. With a physical SIM, this means swapping cards or risking roaming charges.

An eSIM lets you avoid that. It sits alongside your existing SIM and works only for data. So your personal number stays active for OTPs, bank calls, or emergencies  while your eSIM handles the internet in Singapore.

This is a big win for business travellers, students, and even digital nomads who need to juggle both.

Network coverage and reliability

Singapore has strong mobile infrastructure. eSIMs connect to top local providers like Singtel, StarHub, or M1, depending on the provider you choose.

Whether you’re at Changi Airport, Marina Bay Sands, or taking a cab through Little India, your signal won’t drop.

No difference from a regular SIM. Same coverage. Same speed. Just no hassle.

Important Notes Before Singapore eSIM Activation

Before you scan that QR code, there are a few things to check. Not all phones support eSIM, and not all plans work the same. Knowing these details saves you from problems later.

Singapore eSIM activation is simple but only when your device, OS version, and travel plan match the provider’s requirements. Here’s what to review before buying:

Device compatibility checklist

Your phone needs to support eSIM. But that’s not all. Some older models might support it only on specific carriers or firmware versions.

• iPhones: iPhone XS and newer
• Androids: Google Pixel 3+, Samsung S20+, and recent OnePlus models
• Huawei: Most models don’t support eSIM check before purchase

Also, if you’ve bought your phone from China or Korea, double-check. Some regional variants don’t allow eSIM at all.

Roaming, hotspot, and fair-use policies

Some tourist eSIM plans block tethering or slow down after a data cap. Others might auto-switch networks or throttle speed after a few GBs.

Make sure to check:

• If hotspot is allowed
• If the speed drops after a certain usage
• If roaming outside Singapore is possible (in case of layovers)

Also, keep in mind that some eSIMs use international data aggregators. Your IP may show a different country. That’s fine for browsing but may affect banking apps or local services.

Lastly, your data is secure but only if the provider encrypts your connection. For more on this, check our detailed eSIM security guide.

Refunds, plan validity, and renewals

eSIMs are digital once activated, most providers don’t offer refunds. Even if the plan doesn’t work on your phone, you may not get your money back.

Always read the fine print:

• Some plans start immediately after purchase
• Others only activate once scanned
• Many tourist plans expire in 7 to 30 days  no extensions allowed

If you’re planning to stay longer, choose a provider that allows top-ups or auto-renewals. That way, you don’t lose data mid-trip.

Step-by-Step Guide to Buy and Set Up an eSIM in Singapore

Worried the setup will be tough? It’s actually simple. The eSIM setup process in Singapore usually takes less than five minutes. You don’t even need to remove your existing SIM.

Follow these easy steps to get started:

• Choose your eSIM provider: Pick a trusted brand that offers local coverage. Some even give a free trial. Compare data limits, validity, and top-up options before you buy.
• Check device compatibility: Make sure your phone supports eSIM. You can find the full list on the provider’s FAQ page or your phone’s settings.
• Buy the plan online: Go to the provider’s website, pick a plan, and pay. You’ll instantly get a QR code on email or in the dashboard.
• Scan the QR code: Open your phone’s settings → go to “Mobile Network” → tap on “Add eSIM” → scan the code. Done!
• Set data SIM preference: If you’re using both physical and eSIM, choose the eSIM for mobile data. Keep your personal SIM active for calls or OTPs.
• Turn off airplane mode: Once you land in Singapore, switch off flight mode. Your phone will catch the network, and data will start working.

Why Tourists Prefer eSIM Over Local SIM Cards in Singapore

You’ve just landed. You’re tired. You want to book a cab, share your hotel location, maybe check the route to your hostel. But if you’re still stuck hunting for a SIM shop, you’re already behind.

That’s where the tourist eSIM Singapore plans change the game. No need to queue at the airport. No forms. No waiting for the shop to open. You just switch off airplane mode, and the data starts.

For short-term trips, local SIMs don’t really offer much advantage. They need ID verification. Some need KYC. Others have expiry rules that aren’t clear until after you’ve paid.

And what if you’re not staying near Orchard or Bugis? Most physical SIM counters are in touristy zones. If you’re in the heartlands or outer districts, it gets harder to find one.

On the other hand, with an eSIM, everything is done online. Scan. Activate. Use. You even get the choice to switch plans if the signal is weak or the data finishes early.

Sometimes things don’t go as smoothly as planned. Even with eSIMs, setup can hit small bumps. But don’t worry most issues are quick to fix with a little patience.

QR not scanning or plan not loading

The most common issue is the QR code not scanning. Sometimes the camera doesn’t focus well. Or the screen brightness is too low. Try these steps:

• Increase your screen brightness.
• Hold the phone steady and wait 5–10 seconds.
• Avoid glare or dirty camera lenses.

If your QR still fails, don’t panic. Most providers also give you manual setup details just enter the SM-DP+ address and activation code. This always works.

No network or slow data

If your eSIM shows “installed” but no signal:

• Make sure Mobile Data is turned on for the eSIM.
• Open SIM settings and switch to 4G or LTE.
• Turn on Data Roaming (yes, for eSIM it’s needed).

Sometimes it takes a few minutes for the network to connect, especially in buildings or underground stations.

Still slow? Restart your phone. This usually fixes it.

Switching plans or deleting an eSIM

Want to switch to a new eSIM plan?

1. Go to Settings → Mobile Plans
2. Tap the current eSIM profile
3. Choose Remove Mobile Plan

Once deleted, you can add a new QR or setup manually again.

Note: Some providers lock profiles for a limited time. Always read the refund and renewal policies first.

Conclusion

You’ve probably spent hours planning your trip: flight tickets, hotel bookings, travel insurance, must-visit food spots at Lau Pa Sat, maybe even a day trip to Sentosa. But what about staying connected?

With over 80 million visitors to Jewel Changi Airport last year, you’re not the only one landing in Singapore for a short trip or business stop. And most travelers are ditching physical SIMs.

Buying a tourist SIM after arrival means queues, passport checks, store-hopping, and risky roaming charges. But with an eSIM, your phone gets connected even before you pick up your luggage.

All it takes is one QR code, no tray, no tools. Plans start from just a few dollars. And setup? Barely five minutes.

So before you board your flight, do one last thing: Buy eSIM Singapore and land connected, ready, and stress-free.

Frequently Asked Questions

Which eSIM is best for Singapore tourists?

If you’re visiting for just a few days, look for plans that offer unlimited data with fair usage. Travelers prefer options that activate instantly and don’t ask for ID proof. Providers like Baztel, Airalo, and aloSIM are popular because they support quick activation and multiple top-up choices. Always compare the coverage, plan validity, and whether you get customer support before choosing the best eSIM Singapore plans.

How do I activate an eSIM in Singapore?

Once you buy an eSIM online, you’ll get a QR code on email or on your screen. Just open your phone’s settings and scan it under the Mobile Network or SIM section. Activation takes 2 to 5 minutes. For Android and iPhones, the steps may differ slightly. You can follow our how-to guides for activation for step-by-step help.

Can I buy an eSIM at Changi Airport or should I buy online?

Yes, some counters at Changi sell physical and digital SIMs. But lines are long, shops may close early, and plans are usually more expensive. Tourists who want to save time and skip paperwork prefer buying a travel eSIM for Singapore online. This lets you activate before landing your internet works the moment you turn off flight mode.

Are there any hidden fees with eSIM plans?

Most tourist eSIM plans are prepaid, so there are no extra charges if you use them for data only. But always read the terms. Some providers reduce speed after a certain data limit (FUP), or charge more for voice calls. Always look for the fair usage policy and see if there’s a top-up option to continue service without surprise bills.

Can I keep my primary number and use eSIM for data and calls?

Yes. That’s one of the biggest advantages of eSIM. Your physical SIM stays active for OTPs, home-country calls, or WhatsApp. You can set the eSIM as the primary for mobile data and still receive messages on your original number. Phones with dual SIM support handle this easily.
