常见问题
Does tethering use more data than using the phone directly?+
Sharing itself adds nothing, but what joins usually consumes more, because laptops and tablets are not as frugal as phones: system updates, cloud sync and higher-resolution video on a bigger screen all add up. If a laptop will be attached, mark the network as metered and switch automatic updates off first.
How do I find out whether a plan permits sharing?+
Read the hotspot line in the listing, and if there is none, ask the seller before buying, because it is a provider condition rather than a hardware feature. Keep the answer as a message or screenshot so that, if sharing fails after installation, the conversation starts from agreed terms. If you are buying from us, ask on LINE @esimonline or at esimonline.asia@gmail.com beforehand.
How many devices can connect at once?+
That is set mainly by the host handset, and it differs by model and OS version; some plans add conditions of their own. The tell is that the first devices join normally and the next one cannot connect at all. The immediate fix is to disconnect something idle. In practice, the more devices you attach, the less speed each one gets anyway.
Why do devices connect but nothing loads?+
Usually the host phone is not really on the network, or the allowance is finished. Turn the hotspot off and try loading a page on that phone directly. If it also fails, fix the underlying connection first: cycle airplane mode, check network selection, and confirm data roaming is set for that profile as the seller instructed.
Is a USB cable better than a wifi hotspot?+
For long laptop sessions it usually is, because it holds up better where wifi is congested and the phone charges while connected. The limits are that it serves one device and needs a cable that actually carries data rather than only power. When several people or devices need the connection, the wifi hotspot is still the practical choice.
One plan shared by the group, or a plan each?+
If everyone stays together and use is light, one shared plan is cheaper and enough. If people will split up, or someone has real work to do, individual plans remove a lot of friction, since nobody depends on how close the host phone is or how much battery it has left. A good middle path is to have two people in the group carry plans, so there is a fallback whenever you separate.
