2 GB eSIM Mobile Internet 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 5GB. That covers maps, social media, WhatsApp, and uploading photos.

For business travelers who need video calls or use a hotspot, we recommend 10GB or 20GB 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.

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.

Your 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 regional package that includes coverage for your home country. Example: Europe → Germany).

The countdown begins only when your eSIM connects to a mobile network at your destination. For this to happen, your eSIM must be turned on, selected as your mobile data line, and have data roaming enabled.

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. You can install it anytime - even weeks before your trip. Installation does not start the validity period.

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.

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. After your eSIM expires or runs out of data, you have 160 days to top up to regain the internet connection on the same eSIM.

The eSIM for Singapore works exclusively as a single-country plan. This means it only functions within the country's borders since it's designed to connect to local networks.

Planning to visit multiple countries? Consider our regional eSIMs for seamless connectivity across borders. This way, you can stay connected throughout your journey without needing to buy and switch numerous eSIMs. For broader coverage, check out our best eSIM plans for different regions.

You can easily return to your original mobile data settings at any time. That's why eSIMs are a safe and convenient solution for travelers! After your trip, go to the mobile data/network settings and choose your main carrier as the mobile data provider.

eSIM prices for Singapore start at $4.50.
