常见问题
If I do not know whether my plan counts hours or days, where do I check?+
Check the plan detail page at purchase and the order confirmation email. Both usually state the time unit clearly. If it is still unclear, contact support before you travel.
Does installing the profile several days before flying use up validity?+
Generally not, since the clock usually starts on the first successful network connection, not on installation. Always confirm against your specific plan's terms to be sure.
How do I know if a late-night landing has cost me a day?+
Open the app and check the recorded activation time against your actual landing time. On a day-based plan, if the two straddle midnight, that day may well have counted as day one even though little of it remained.
Does a regional plan covering several countries count validity separately per country?+
No, most run as one continuous block for the whole trip and do not pause at a border crossing. Add up the whole trip's days before choosing the plan length.
Does leftover data come back if I buy a new plan after expiry?+
No, leftover data disappears at expiry and is not transferred to a new plan. A new plan starts its own data allowance and validity clock from scratch.
If a trip runs longer than planned, what should I do about a plan nearing expiry?+
Check the remaining-time counter in the app and top up or buy a new plan before the current one expires. Do not leave it to the last moment, as connectivity can gap while you are in the process of buying.
Is an hour-based or day-based plan better?+
Neither is universally better; it depends on your trip pattern. Hour-based counting is fair to whatever time you activate, while day-based counting is often easier to reason about when a trip has a clear start and end date.
