there are two packages for on-net (ntl) and off-net (bt) customers...
for
on net customers the options are...
(you must have an ntl phone line)
unlimited package - £12.49 per month
pay as you go package - 3p per minute weekdays, 2p per minute weekday evenings and 1p per minute weekends (with 5p connection charge).
for
off-net customers the option is ntl:freedom
www.ntlfreedom.com
(you must have a bt phone line)
here you can get a number of packages including
ntl:freedom unlimited 12.49 a month
so the ntl on net package would depend on your phoneline because you would need an ntl line installed
but the off net packages should not matter as long as you are on the bt network, aless he was trying to get broadband (adsl) not dial up
