常见问题
If I switch on airplane mode right after installing, does the clock start?+
Not for a first-connection plan, since the clock waits until the phone has actually registered on the destination network. Installing alone without connecting does not move it. For an on-purchase plan, the clock already started when the profile was issued, regardless of airplane mode.
I bought it at home and arrived at the destination later than planned — does that matter?+
For a first-connection plan it makes no difference, since the clock follows the actual connection time, not the original plan. For an on-purchase plan the clock has been running since the purchase date, so arriving later simply leaves fewer usable days.
Can I move the same profile to a different phone mid-trip?+
A profile can usually be installed only once and binds to the first device it lands on. Moving it to a new phone mid-trip is generally not possible, so contact the team to see what options exist for your specific case.
What happens if I buy a first-connection plan and never actually travel?+
The clock does not start, since registration with a destination network never happened, and the profile stays in an unused state. Check your own order page for any refund or usage terms, though, since that is a separate matter from the validity clock itself.
Does a multi-country regional plan count days separately per country?+
No, it uses one clock and one profile for the whole trip. Moving between countries within the same coverage list does not restart the clock.
Why does the shown expiry time not match my local time?+
The day-counting method depends on each provider's own system, which may run on destination time, the provider's own system time, or a flat twenty-four-hour cycle. Treat the number of days stated in your order as the reliable figure and always build in a buffer.
If I top up data mid-trip, does it extend my existing expiry date?+
It depends on the specific top-up option: some extend the existing date, others arrive as a fresh data block with their own separate expiry. Always read that option's own details before confirming.
