よくある質問
Does activating later than the purchase date forfeit the plan?+
No, not as long as it is still within whatever window the plan allows for activation. Check the plan's page for whether there is a maximum time limit before it must be activated.
Do I need to switch off the original main SIM before activating the new profile?+
No, it does not need to be switched off. Devices that support dual SIM can run both at once — simply choose which SIM is the default data route in the settings menu.
Does using airplane mode during a flight affect the profile?+
No, it does not — airplane mode simply switches off every connection temporarily. Once airplane mode is turned off after landing, the profile remains fully intact and reconnects normally.
Why does the network name shown not match what I expected?+
A travel profile often connects through a local partner network, which may show a different name from the main operator you are used to. This is normal behaviour for cross-network roaming.
How many times can a profile be activated?+
The data roaming switch for the same profile can be toggled on and off as many times as needed, provided the profile has not been deleted from the device.
If I change devices mid-trip, does the profile still work?+
It will not work on a new device, since it is tied only to the original device it was installed on. In this case, a new plan would need to be bought for the new device.
Do I need to toggle airplane mode before activating?+
Not always — turning on the profile's data-roaming switch directly is usually enough. Toggling airplane mode on and off is simply a way to refresh the network search when signal has not yet appeared.
Does switching the main SIM back and forth mid-trip affect an already-active profile?+
No, it does not — the active eSIM profile keeps its status. Just check the default data route still points to that profile after switching the SIM back.
What if the wrong profile gets activated on a device holding several?+
Switch off roaming for the wrong profile, then switch on the one actually needed. It can be switched back and forth as needed with no downside.
Common questions in this section
When does plan validity start?+
On a first-connection plan the clock starts when your phone first registers on a destination network. On an on-purchase plan it starts when the profile is issued. Every plan page states this in the Activation line, and your order stores the rule as it was at the time of purchase.
Does leftover data disappear when the plan expires?+
Yes. Leftover data does not carry over to a new plan and is not refunded. Choose a validity that matches your trip, and if you are running low, top up before expiry rather than after.
What do I do right after landing?+
1) turn on the eSIM line, 2) set mobile data to it, 3) enable data roaming for it, 4) disable data roaming on your home SIM, 5) toggle airplane mode once. You normally have service within a minute or two of leaving airplane mode.
Which time zone does the validity follow?+
Validity follows what the plan's terms state: either hours counted from activation, or days as defined by the provider. Check the plan page and your confirmation email, because with day-based counting a late-night landing can quietly cost you a day.
I activated too early by mistake. What now?+
Contact us straight away with the order number and we will check with the supplier whether it can be paused or reset. Many plans cannot be stopped once the clock starts. Meanwhile turn that profile's data off so no more allowance is consumed, and do not delete the profile.
When does the validity period start?+
Usually from the first time the profile attaches to a network, not from purchase or installation. The binding terms are the plan's own, stated on its page before payment.
The phone is stuck searching for a network after install+
Toggle airplane mode for ten seconds, then check that the profile is enabled, set as the data line, and has data roaming switched on for that profile.
