This number differs by plan and by the underlying network provider — there is no single figure that applies to every plan. Always check the specific plan page you bought.

Yes, it has. The system does not distinguish an intentional connection from an accidental one — the moment the phone successfully connects to the destination network for the first time, the usage period begins.

Yes, as far as usage time goes, since it does not start until first connection. But you must make that first connection within the activation window stated on the plan page, which may be shorter than you expect.

Possible in some cases, but the detail depends on the existing plan's status and the underlying provider's terms. Talk to us before deciding to buy again.

Yes. Each plan may come from a different underlying provider, so each carries its own separate window. Note each one's expiry separately rather than remembering one combined figure.

Message us right away with the order number. We will check that plan's real status against the underlying provider's terms and let you know what options exist, rather than assuming nothing can be done at all.
