I don't know what your circumstances are but I am of the same opinion as "gengiscant" with regards to "dial-up". There are some very reasonably priced "Broadband Packages" about these days which you should consider. Life will be a lot easier with Broadband and within a very short time you will wonder how you ever managed without it.
You are already with BT - there is a current offer of £6.99 (for first 3 months) then £13.99 after that. - View details here - but offer due to end soon. (This is advice only - I am in no way connected to BT - But I do have BT Total Braodband myself) click here
