常见问题
Can an eSIM genuinely be installed with no Wi-Fi at all?+
Yes, as long as internet is available from another source, such as the home SIM's own mobile data or a hotspot shared from another device, since installation only needs an internet connection, not specifically Wi-Fi.
Does using the home SIM's roaming data to install cost anything?+
It depends on the home SIM operator's own terms in that particular country, which differ between operators. It is always worth checking with the operator before switching it on.
If the profile is downloaded in advance at home, can it be activated whenever?+
Activation conditions differ by plan; some begin counting the validity period the moment the destination network is first joined. Reading the specific plan's detail page before deciding when to activate is worth doing.
What to do if airport Wi-Fi requires a local number that is not available?+
Use the home SIM's data instead, or ask to share a hotspot from someone else travelling in the group — there is no way around that specific network's own requirement from the user's side.
Can a friend's shared hotspot be used to install?+
Yes, it works the same way Wi-Fi would. The sharing steps sit in the settings of whichever device is sharing, in a menu position that varies by device model.
