If you’re flying Singapore Airlines, the fastest and most reliable way to get online as soon as you land is to set up your eSIM before departure so you can skip airport queues, avoid roaming fees, and start using data the moment you switch off airplane mode. This matters even more on long-haul routes where you’ll want instant maps, transport apps, and hotel check-ins ready to go the second you arrive.

Why You Should Set Up an eSIM Before Boarding Your Singapore Airlines Flight
If you’re wondering whether you should buy mobile data before flying, the answer is yes—especially on Singapore Airlines routes where landing often means navigating big airports, accessing transport, and using digital immigration forms. Before we dig in, here’s a quick refresher on what an eSIM card is through this helpful guide: what is an eSIM card.
For long-haul travelers, having your Singapore Airlines eSIM installed before takeoff ensures you can bypass expensive in-flight connectivity packages and avoid depending on patchy free airport Wi-Fi. Whether you’re traveling for work or leisure, you’ll want a stable connection right away—and an eSIM for international travel gives you that reliability.
Here’s why it matters:
- You avoid unpredictable roaming charges from your home carrier.
- You get instant connectivity upon landing—no kiosks or physical SIMs needed.
- You can select the best travel eSIM for your destination before your trip begins.
- Singapore Airlines cabins often encourage digital boarding passes, online menus, and app-based entertainment—all easier with a connected device when needed.
If you’re flying into major hubs like Singapore Changi, Tokyo, London, or Sydney, installing your Singapore Airlines eSIM ahead of time saves precious minutes and ensures your first steps after landing are stress-free.
Understanding In-Flight Connectivity and Its Limitations
Singapore Airlines offers Wi-Fi connectivity on most medium- and long-haul aircraft, including A350, B787, and A380 fleets. While free messaging plans are available for KrisFlyer members, full browsing packages can be costly—especially if all you need is navigation or a few quick uploads.
Here’s what you need to know:
- In-flight Wi-Fi varies depending on your aircraft type.
- Speeds may slow down during peak usage.
- Data-intensive tasks (cloud backups, video calls) may be restricted.
- Some travelers prefer to stay offline until landing but still need instant data afterward.
Because of these limitations, many passengers turn to a Singapore Airlines eSIM instead. By having your digital SIM preloaded, you can simply activate your plan when you switch off airplane mode.

How a Singapore Airlines eSIM Works When You Land
When you have an eSIM installed, here’s what happens after touchdown:
- You turn off airplane mode.
- Your phone digitally activates the eSIM.
- You instantly connect to a local partner network.
- You open maps, ride-hailing apps, translator apps, and hotel bookings right away.
This is especially useful when you:
- Fly solo and need directions immediately.
- Arrive late at night.
- Don’t want to be stuck looking for a SIM counter.
- Need to coordinate meet-ups or business logistics.
An eSIM for international travel is simply the most efficient way to stay online when flying region-to-region, and Yoho Mobile partners with major operators worldwide for fast and reliable connections.

Setting up your Singapore Airlines eSIM is surprisingly easy. You can do it at home, at the airport, or even while boarding—just make sure you have Wi-Fi.

Install Your eSIM on Your Device
Open your phone settings and go to the Add eSIM or Mobile Data/Cellular section. Scan the QR code or enter the activation code. -

Test the Connection Before You Fly
You can check that the eSIM is installed (without activating the plan) by toggling the line on and off. Do not activate the plan unless your Yoho plan supports pre-activation. -
Switch to Your eSIM at Landing
When you turn off airplane mode, your eSIM will automatically connect to the best available partner network.
Travelers often mention how much smoother arrival feels with a preloaded Singapore Airlines eSIM—especially when connecting to transit apps like Grab, Uber, Bolt, or Metro maps without delay.
If you’re traveling soon, it’s a great time to secure your plan early. Many frequent flyers prefer to preload their Yoho eSIM before departure to avoid last-minute airport stress.
