分享给多台设备使用的 eSIM

No, not every one. Check the tethering line on the plan page every time before buying, since some plans restrict or don't allow it at all.

It depends on the phone's own hotspot limit as the host device, not the eSIM plan itself. Check that specific phone's own specification.

Often yes, especially with automatic system updates and cloud sync left on. Turn both off before relying on a shared plan.

Not directly — everyone draws from the same pool. Agree on usage norms within the group, or consider separate plans if habits differ a lot.

This is usually the daily full-speed threshold being reached on an unlimited plan, which affects every device sharing that connection at once, not a fault with any one device in particular.

No — setting a password is a setting on the phone itself and has nothing to do with the eSIM plan you bought.

The maximum is a limit of the host phone, not of the plan, and it differs by model and OS version. In practice, the more devices connected simultaneously, the less speed each one gets and the faster the host heats up. If you genuinely need several, connect only the ones actually in use.

Yes. A hotspot creates an ordinary Wi-Fi network that any device can join, regardless of the client's brand or operating system. What matters is that the host's plan permits sharing and that the host phone supports eSIM and is not carrier-locked.

Because every device shares the same single connection. The more people streaming or uploading at the same moment, the smaller each share becomes. Speed also depends on the signal where you are standing and how busy that area is, neither of which is under your control or ours.

It depends on how you travel. If the group stays together most of the day and use is light, one shared plan is usually better value. If people split up often, or someone has real online work to do, separate plans mean nobody waits on anybody else and no single phone's battery becomes everyone's problem.

You can, but the battery drains far faster and the phone stays warm. More importantly, devices that joined before will rejoin by themselves whenever they are in range and sync in the background unnoticed. Switch it off when it is not needed, and always once you are back and everyone is on the room's Wi-Fi.

Do not guess. Message us on LINE or by email with the plan name and destination before you buy. Whether sharing is permitted is set per plan and per country, so there is no general rule we can give. If sharing is essential to your trip, get it confirmed before paying.
