常见问题
Does validity always start from the purchase date?+
Not always. Many plans count from the first network attach instead. Check the specific plan's own details page.
Does installing the profile at home start the validity clock?+
Generally, installation alone does not start validity if the plan counts from first network attach. Still confirm that specific plan's actual terms to be sure.
How far ahead of travelling is it safe to buy?+
There is no universal number that always applies; it depends on each plan's own terms. Read the plan's details page before every purchase.
If several plans are bought for the same trip, are their validity clocks tied together?+
No, each plan's validity counts independently under its own terms. Activating one does not affect another's validity.
What should I do if the plan page's terms are still unclear?+
Ask before deciding to buy, via LINE or email. Do not guess and purchase before being sure.
