常见问题

Can I also switch on roaming for the home SIM as a backup signal?+

Technically yes, but it is not recommended, since it typically carries a roaming charge from your home country provider that runs far higher than usual. Rely on the eSIM line as the main connection instead, and keep the home SIM's roaming switched off.

Why is there still no signal even after switching on the eSIM's roaming?+

It may be that the phone has not yet connected to a partner network at all. Try briefly toggling airplane mode, or move to a spot where signal should be better. If that still does not help, contact the team.

Does leaving airplane mode on for the whole trip save on charges?+

Not in the way intended, since airplane mode disables every line's connection, including the eSIM already paid for. The correct approach is to switch off only the home SIM's data roaming.

Does a regional plan need roaming switched on and off again every time you cross a country?+

No. As long as roaming for the eSIM line stays switched on, the phone connects to whichever partner network suits each country automatically when you cross a border.

If the setup was wrong and a charge came through on the home SIM, what should I do?+

That is a matter for your home SIM's own provider directly, not the eSIM plan bought from us. Contact your home provider about that specific charge, and make sure the home SIM's roaming setting is off before your next trip.

Should roaming be switched on before boarding, or is it fine to wait until arrival?+

It is fine to switch it on before boarding, since turning on roaming for the eSIM line does not connect to anything until the phone actually finds a partner network at the destination. Setting it up in advance saves having to hunt through menus right after landing.
