#129: Emergency calling credit

Parents can easily get hold of emergency-only phones, but try insisting that your fashion-conscious teenage offspring carry one. Danger-conscious parents, on the other hand, (sometimes maligned as “overprotective”) would all like a way to use their child’s existing mobile phone as a tool by which their scared, lost or soaking wet progeny can call home.

My problem has been that the credit on phones is not partitioned: it can easily be exhausted by chatting to a boyfriend for the required three hours.


Today’s invention is therefore to arrange that each phone plan incorporate a reserved calling credit partition, linked to a single emergency number. This will probably be charged at the ultra-ultra-premium-eltonjohn-diamonds-and-platinum rate, but at least it will never run out of calling credit.
