I am considering dumping my present ISP for o2.i am currently with BT and have been with them for 5years.i feel the option 3 bt broadband is expensive im paying £39 per month for broadband and telephone line rental.i am also getting annoyed of the cold calling of bt's indian call centres. with o2 as a mobile customer i can get broadband from £7.50 up to 8 meg and up to 16 meg for £10.
