配置文件状态 是什么意思
状态很重要，因为它决定你还能做什么。已下载但停用的配置文件可以重新打开；已删除的通常没办法用原本的 QR 装回来。清空手机之前，先确认这一点。

常见问题
If I disable the profile, does the validity countdown pause?+
On most plans it does not, because validity is normally counted in real time from first use rather than only while the profile is switched on. That detail belongs to each supplier's terms, so read the ones attached to the plan you actually hold instead of comparing with a plan you used before. What disabling does reliably achieve is stopping background apps from drawing on the allowance while you are not using it.
I deleted the profile — can I reinstall it from the original QR code?+
Generally no. A QR code is normally designed to be redeemed once, and after that the system treats it as used. Recovering the line means asking the supplier to issue a new profile, which depends entirely on their policy: some will under certain conditions, some will not. Contact them with your order reference as early as you can, rather than waiting until the trip is nearly over.
The profile is enabled but there is still no data. What should I check first?+
Check two things first. One, whether the handset has actually been told to send mobile data through that profile, because enabling a line and choosing it for data are separate switches. Two, whether roaming is permitted on that profile, since many travel eSIMs work by attaching to a local network as a visitor. If both are set and there is still nothing, cycle flight mode once, then contact support with your handset details and the country you are in.
Will a factory reset remove my eSIM?+
Assume it will. A reset clears data on the handset, installed profiles included. Some models and some OS versions ask whether to keep the eSIM, but not all do, and you should not plan around getting that prompt. Before resetting, confirm with your supplier whether this profile can be reissued or transferred, and decide from there.
Should I enable the profile before leaving, or wait until I arrive?+
Install while you are somewhere with stable Wi-Fi, because installation itself needs internet, but leave the profile disabled and switch it on when you arrive. The reason is that many plans start counting from the moment the profile first attaches to a network, so enabling it days early can waste the first day. The exact trigger differs by supplier, so read the plan's terms before deciding.
How do I tell which profile is which when the names all look alike?+
The practical method is to enable them one at a time and watch which network the phone attaches to and whether data starts working. Many handsets let you give each profile a nickname, which is worth doing right after installation — the destination or the trip name works well once several have accumulated. If you are still unsure, match them against the confirmation emails before deleting anything.
