That seems to be good news... Can we expect old days to come back when 0870/0845/0844 were a part of inclusive allowances? Maybe to begin with, retentions would be able to offer such deals if you threaten to leave...
It may be good news Nik, but it's not as rosy as you may have assumed.
If you opened the hyperlink I posted, you will see that, although these numbers are inclusive in the tariffs, they still cost 40p / min. of your credit.
That is not as bad as it sounds, as even on their lowest £35 tariff, you get 5 times as much credit as you paid - which makes the effective charge 8p / min. ( or better on higher tariffs ).
However, that is hardly as good as the old 'inclusive' O2 allowances for 0845 / 0844 / 0870 calls.
