常见问题
How many days before the trip can I install the eSIM?+
You can install as soon as the confirmation email arrives, and you should, while you are still on home Wi-Fi — installing is a separate step from starting the plan. When the validity period begins depends on that supplier's terms, which are stated on the plan page and in your confirmation email, so read them before deciding when to switch the line on.
I only have one phone, so I cannot scan the QR. What now?+
Three routes: open the email on a computer or tablet and scan from that screen, print the QR on paper, or type the server address and activation code in by hand using the manual steps on this page. The last one always works as long as you have the confirmation email.
Once it is installed, do I have to switch the line on straight away?+
No, and we suggest leaving it off until you arrive, since installing does not oblige you to start. Enabling it on arrival also means the phone begins looking for local networks exactly when you need them — but do check your plan's validity terms first.
The connection dropped during installation — what should I do?+
First check whether the eSIM line appears in the phone's list of lines and whether its details look complete. If it is missing or looks wrong, do not rescan the QR yourself — contact us on LINE at https://lin.ee/skDPoNx or by email at esimonline.asia@gmail.com with your order number and where it broke off.
How many old profiles can the phone keep?+
The number of profile slots varies by model and OS version, so there is no single figure that fits every phone. If yours says it cannot store another, delete only profiles you have confirmed have expired, and never one that is still valid, since it generally cannot be reinstalled.
It installed fine but there is no signal after landing+
Check three things in order: whether the eSIM line is switched on, whether data roaming is on for it, and whether it is set as the data line. If all three are done and it still fails, toggle airplane mode once, wait five minutes, and continue with the no-signal troubleshooting guide.
