I think you would. Depending on what you're paying already the call package could be a saving anyway with the broadband chucked in for you to try. I'm giving Telewest £25 for line rental and unlimited calls so I might as well switch to CW with international calls and the broadband for £4 less.
RE: I think you would. My TW is £35 a month - £25 for Internet and a tenner for the phone with calls on top (which don't usually amount to more than a couple of quid)
RE: Dunno, but it's cheaper anyway. Could have done with it 5 or 6 years back....used to spend loads on calls to the States.
RE: Go for Cable if you can phone, telly and Broadband all in one lump, opt for direct debit and forget the chuffin bills. you soon get used to just looking at the bill once a month knowing its gettin paid when youve budgeted for it. Its worth it for the sress relief. and when weve chewed it over in the pub there doesnt seem to be BIG differences in any of em
