常见问题
If a plan does not support hotspot, does it work at all partially?+
No. Sharing simply will not work at all if the plan does not support it — it is not a case of working slower or partially. Check the 'Hotspot' line on the plan page before buying if you need this feature.
If a friend uses a lot of data through my hotspot, does it affect my own allowance?+
Yes, definitely, since shared data comes from exactly the same allowance you use yourself, not a separate quota. It is worth agreeing roughly how much they expect to use before sharing.
Why does turning on the hotspot still seem to use my original SIM's roaming data?+
This usually happens when the wrong line is set as the primary data line on a dual-SIM phone. Check the settings menu to confirm the selected primary data line is genuinely this plan's eSIM.
How many devices can connect to the hotspot at once?+
It depends on the phone's own limit, not on any condition of the plan. Check your phone's own hotspot settings menu for the figure.
Why does a laptop burn through data unusually fast even though nothing seems open on screen?+
This is usually operating system or application updates, or cloud file syncing, running continuously in the background. Turn these off before connecting to the hotspot.
When should a travel companion buy their own separate plan instead of continuing to share a hotspot?+
When their usage is nearly as heavy as yours throughout the trip. A separate plan of their own is usually better value and avoids splitting one shared quota.
Does running a hotspot use data faster than using it on the phone itself?+
The sharing itself adds no meaningful overhead. What drains an allowance is the behaviour of the device that joins: laptops and tablets download updates, sync files, and play video at higher resolutions than a phone does. Configure the joining device to be careful first and the difference shrinks considerably.
Can I share a hotspot with a friend whose phone is a different brand?+
Yes. A Wi-Fi hotspot is a common standard that devices of any brand and operating system can join; all they need is the password. USB and Bluetooth sharing can have extra constraints depending on the specific pair of devices.
Why does the hotspot switch itself off when I did not turn it off?+
Three reasons come up most often: the phone is too hot and is throttling, the battery has fallen far enough for a power-saving mode to shut down demanding features, or the operating system turned sharing off automatically because nothing had been connected for a while. That last behaviour varies by manufacturer and OS version.
Do I need to turn the hotspot off before boarding a flight?+
Turning on airplane mode cuts both the cellular link and sharing anyway, but switching the hotspot off by hand beforehand is a good habit: some phones restore it automatically when you leave airplane mode after landing, and you may not notice that it is sharing again.
What if the plan page says nothing about hotspot use?+
Do not assume it is allowed — ask before buying, because this condition depends on the network supplier behind each plan and is not uniform across the catalogue. Message us on LINE at https://lin.ee/skDPoNx or email esimonline.asia@gmail.com with the plan name and your destination, and we will check before you pay.
Can I run the hotspot from the eSIM while my home line is still active?+
You can on a device that supports two active lines, but confirm that the line the system uses for data is the eSIM and not your home number — otherwise the hotspot shares the home line and may incur roaming charges. That setting sits somewhere separate from the hotspot switch, and its name varies by manufacturer.
