Best 1 GB eSIM for Singapore 🇸🇬

Yes. Sentosa has full coverage from all three networks. Your eSIM works at Universal Studios, the beaches, hotels, everywhere on the island.
You can use Google Maps to get around, book activities online, or post photos on social media. Signal quality matches central Singapore. No problems when you cross the bridge to Sentosa.

Three to five days - travelers usually buy 5 GB. That covers maps, social media, WhatsApp, and uploading photos.

For business travelers who need video calls or use a hotspot, we recommend 10 GB or 20 GB data plans, depending on the specific work requirements. If you're uploading or downloading big files and have several HQ video calls, you might need to top up your eSIM. All it takes is selecting the top-up and completing the purchase. We'll activate extra data without any extra setup on your end.

If you installed your eSIM before the trip, you'll get internet as soon as you turn it on. When the plane lands, go to settings and enable the eSIM. Select it as your mobile data line and turn on data roaming. Connection starts within a few minutes, sometimes in seconds.
This means you can check directions, book a Grab, or message your hotel while waiting for luggage. Changi Airport has strong coverage in all terminals.

No. Your Singapore eSIM only works within Singapore's borders. If you take a day trip to Malaysia, you'll lose connection once you cross the border.

For trips covering both countries, consider getting a regional Asia eSIM instead. This eSIM works across multiple countries, including Singapore, Malaysia, Thailand, and others. You install it once and stay connected everywhere you travel in the region.

If you already bought a Singapore-only eSIM and decide to visit Malaysia, you can purchase a separate Malaysia eSIM with a small data plan. Many devices let you install several eSIMs, but usually only one can be active. In your settings, turn off your Singapore eSIM and turn on the Malaysia eSIM when you cross the border. Then follow the usual activation steps: select the eSIM for mobile data and enable data roaming. Your phone will connect to a Malaysian network.

Singapore eSIM is for business travelers, holidaymakers, and transit visitors exploring Changi Airport, Marina Bay Sands, or Sentosa Island. Having a dedicated eSIM gives your device mobile internet access to ride-hail via Grab, pay MRT fares with SimplyGo, and navigate urban transit routes without removing your primary physical SIM card.

No official ID submissions, passport photos, or identity verification processes are required before setting up your connection. Simply choose your data allowance online, complete checkout, and scan your digital QR code to configure the mobile profile directly on your smartphone.

Yes! You can purchase your travel eSIM even after arriving at your destination. The only difference from buying it before your trip is that we'll guide you to activate it immediately, allowing you to connect to a local network right away.

With travel eSIM you decide when to buy it - either before the travels, on the go using WonderConnect app, or after you arrive at your destination.

Usually, an eSIM plan starts when you first connect to mobile data at your destination.
You can install the eSIM anytime - even weeks before your trip. Installation does not start the validity period (unless you bought an eSIM for your home country; or a package that includes coverage for your home country. Example: Europe → Germany).

The countdown begins when your eSIM connects to a supported mobile network. For this to happen, your eSIM must be turned on and selected as your mobile data line.

eSIM prices for Singapore start at £1.50.

To use an eSIM, your device needs to be eSIM-compatible and carrier-unlocked. If you find your phone on our compatibility list, it most likely supports eSIM technology. In some cases, eSIM compatibility depends on where your phone model was manufactured. That's why we advise you to check our list before you buy one of our Singapore eSIM plans.

Carrier-unlocked means your home carrier (your mobile service provider) isn't restricting your phone from connecting to other networks. While carrier locks are becoming less common, if you're unsure, it's best to contact your provider. Just ask if they allow the use of digital SIM cards/eSIMs. If they do, you're free to avoid high roaming costs and enjoy affordable eSIM mobile data!

Setting up your eSIM requires 2 steps: installation and mobile data activation.

Step 1: Install your eSIM

Your eSIM for Singapore is ready to install immediately after purchase.

To install, choose one of these methods:
• Scan the QR code we sent you right after purchase
• Use the WonderConnect app with step-by-step installation guide and illustrations

Step 2: Activate mobile data (at your destination)

Once you arrive, complete these 4 steps:
1. In your phone settings, turn on your eSIM
2. Select the Singapore eSIM as your mobile data line
3. Enable data roaming for your eSIM (required to connect to foreign networks)
4. Turn off WiFi and test the connection by opening any website

Connection usually happens within seconds, but can take up to 10 minutes for your phone to catch the foreign network signal.
If you are using the WonderConnect app, activation instructions are accessible from the home screen.

You can buy an eSIM for vacation online from WonderConnect on this website or WonderConnect mobile app. Choose a suitable data plan, install the eSIM on your phone, and activate it following provided instructions. Singapore eSIMs start from £1.50.

Yes! Most modern smartphones support dual SIM, which means you can use both your physical SIM card and the WonderConnect eSIM simultaneously.

You install the eSIM and it works alongside your regular SIM card. You don't have to remove it from your phone.

Set the eSIM as your mobile data line. For your regular SIM card, you have two options:

• Turn it off completely to avoid roaming charges for incoming calls
• Keep it on for receiving calls and text messages

Don't worry - turning off your SIM card doesn't delete your number or contacts. You can turn it back on anytime directly from your phone settings

You can top up your Singapore eSIM using the WonderConnect app or through your web account.

Log in to your account, if you have several eSIMs, select the one you want to top up and choose a top-up package. Finalize payment and that's it.

Your top-up activates automatically when your current plan ends or when you run out of data. You can purchase it anytime - even before you need it.

It depends on the plan you select. Different plans offer different coverage - for example, a 1GB plan may cover only the selected destination, while a 10GB plan may also include 10 more countries.

To see exactly where a plan works, select it and check the Coverage section shown under the plan selection.

If you need an eSIM built to cover several countries, choose one of our regional eSIMs.
