More in depth analysis of bills that have have unlimited calls within carrier
My bill beat your site by ~£10 as I make use of an unlimited o2 to o2 call bolt-on your current model does not take into account that despite having say a 500 minute contract, it could be possible to make calls either to landlines or intra-carrier in excess of 2000minutes by opting for a bolt on at contract sign up. O2 for instance offer between 1 and 2 free bolts on many of their contracts.
This was completed a long time ago – our system now has the capability to model these kinds of bundles.
