常见问题
Can I install an eSIM several days before travelling?+
Yes, and it is recommended. But check the Activation section on the plan page first, since some plans start counting validity from the purchase date, not from first connection.
Do I need to switch the line on immediately after installing?+
No, leave the line switched off until arrival is fine. If the plan starts counting validity at first connection, keeping it off does not affect the plan's validity.
Why install at home instead of waiting until the airport?+
Home Wi-Fi is usually more reliable, and there is time to fix things if installation fails, unlike at the airport where time is limited and the connection may be unstable.
How do I know how my plan starts counting validity?+
Open your own plan's details page and read the Activation section, which states this specifically for that plan.
What should I do if installation fails while still at home?+
Do not repeatedly retry the same QR code. Note the error message and contact us on LINE or by email with the order number and device model.
On arrival, what should be done before switching on the eSIM line?+
Check the network settings menu that the eSIM line is set as primary for data, and turn off roaming on the original line before switching on.
