One of the biggest costs of being online is the call charges. This was omitted from your article on Internet Service Providers (NCE 9/30 December 1999).
Virtually all ISPs offer an 0845 number with local charges (the BT daytime rate is 3.36p per minute). Some companies may be using lines provided by cable companies. Most of these will have arrangements with ISPs at local cable-to-cable pricing (around 1.7p per minute daytime).
BT is pushing its low-end ISDN service (Business Highway), but this can prove expensive for basic e-mail and web browsing. There are now other methods of getting online (like a 'permanent' wireless connection), and these may prove more cost effective.
