If we ignore number ranges which whilst regulated are not charged for
(yet), but Ofcom or whoever they are these days are encouraging
operators to make better use of the ranges they have.
To keep a pre-paid mobile on the network you almost certainly need to be
taking up entries in the operators CRM, HLR, AuC, VLR and IN platforms,
all of which have a finite capacity and are often licensed and/or
supported on a per-entry basis. This is not necessarily cheap, and it's
certainly not free - particularly as very few pre-paid customers really
tell the operator when they leave the network (porting aside) and hence
the operator carries that cost liability for the last 6 months of every
subscribers lifecycle regardless of any credit.
One final point from a business finance point of view is that if they
keep the account going indefinitely they will not be able to recognise
the revenue from the voucher as they continue to have a liability to
provide service. From an accounting point of view if they had done this
initially it probably makes no odds, but a wholesale change at this
point would involve a severe skewing of accounts.
Do you see the overhead now?
