There is usually an emergency button that will give a small credit in
the event of you running out.

I have heard that yes (and believe daughter is aware of it).

You still have to pay as it will be
deducted from the next credit added.

Make sense.

I think you can only use it once before adding credit.

That also makes sense. ;-)
