Ones where the credit rolls over and you don't have to make a regular
calls to keep them alive, aren't quite as common as you claim. The
networks hate them because they tend to get used in "glovebox" phones
were they have all the costs of maintaining the number and the billing
records, for virtually no revenue.

Oh come on, its costs them precisely Â£0.00 to maintain a number, its simply

data in a database.

Ah, the marginal costs fallacy rears its ugly head.

The only cost involved in an unused number is the cost to the user when the
phone company disconnects the SIM. The rest of it costs nothing because the
infrastructure would be needed regardless and linking a phone number to a
SIM id is probably a few hundred bytes or less in a DB. You could store the
entire UK phone book and every cellphone IMEI number on a USB stick with room
to
spare never mind a fully fledged datacentre.

Let me know when you need a new spade, if that one wears out.

Ok Mr Telecoms Expert, exactly how much disk space does all the relevant
information about a single cellular phone number take up then? Obviously you
have the figures to hand so please share them.

Nah - whilst I do know the exact figure (or more to the point I could
look it up), it's getting more and more amusing to see you getting
irate when you seem to truly believe that the only cost is the disk
space - something that if it makes up 0.01% of the cost would surprise me.
