I’m on Freeserve Anytime which seems to auto-disconnect every two hours in spite of them claiming in writing that this does not happen. It’s still happening. I’ve also been charged by BT for connection to one of their 24/7 free (as far as BT is concerned) anytime numbers, but in defence they did re-fund 75% of the charges which came to over £100.00p. I used to use AOL which appear to update their software on a daily basis as it’s so full of bugs. I’ve also subscribed to MSN who provided the most reliable service a few years ago.
Most now are only bolt on additions to Explorer anyway (56K) except for broadband, which I will be upgrading to shortly once I can find (any) supplier that’s not on the verge of bankruptcy like Telewest, NTL and others.
