Credit in the pool does not expire, so some families add it once in January and stop thinking about it. How to size that payment, and what happens to whatever is left.
Pause is the quiet switch in the Family page. It stops new SIMs for one person without deleting anything, and it is the right tool more often than a lower limit.
A country list turns a family pool from money anyone can spend anywhere into money for the trip you agreed. Setting it takes a minute per person.
A travel eSIM gives a phone data but not a new number. Once that is clear, most of what works and what does not follows from it.
The technology is the easy part. The harder part is doing it in a way that still makes sense to them on day three of the holiday, when you are not in the room.
A limit works best when it is agreed before the trip, sized to the holiday rather than the worst case, and never used as a way of watching.
The difference is not only the price. It is when you find out what things cost, and who is left holding the bill.
Installing takes a few minutes and a reliable internet connection. The departure lounge rarely offers either.
Hand-me-down phones are where family trips come unstuck. Ten minutes at the kitchen table, a week before you go, settles the question.
