What is a Quick Install link?
A Quick Install link is a convenient feature that lets you install an eSIM by simply tapping a link—no need to scan a QR code. It’s available on iOS 17.4+ and Android 10+. It makes eSIM setup even easier.
Which should I use: the Quick Install link or the QR code?
If you’re using iOS (iPhone) on iOS 17.4+ or Android 10+, we recommend the Quick Install link. Since the eSIM installs automatically just by tapping the link, it’s easier and more reliable—and you won’t need to scan a QR code.
Can I use tethering?
Yes, tethering is available on all plans. You can share your internet connection with multiple devices.
Can I use 5G?
Yes, 5G is available in supported areas. Your smartphone must support 5G.
What is FUP (Fair Usage Policy)?
FUP is the daily cap on high-speed data. If you exceed the cap, your speed will be limited, but you can still use the internet.
What speeds can I expect after throttling?
After throttling, the maximum speed is 128 kbps. You can still send and receive emails and messages, but things like video streaming will be difficult.
Can I use it in multiple countries?
The Global plan and regional roaming plans can be used in multiple countries. The network switches automatically when you cross borders.
Do I get a phone number?
No. This is a data-only eSIM. If you need voice calling, please use apps like LINE or WhatsApp.
