I have a question to ask the LJ brain trust:
Can anybody recommend a good cheap UK dialup ISP that speaks vanilla PPP (i.e., works with Linux and MacOS X without special software), and is unmetered (i.e., won't blow out phone bills wherever I'm calling from)?
You're after FRIACO. This is a special flat-rate deal for Internet dialup only where you pay just for the dialup itself. Cost is typically 15 quid a month, though many places do introductory deals cheaper. We used it when waiting for our DSL to be connected.
DSL, of course, is insanely cheap. Downside is (1) BT suck worse than Telstra (2) fifty quid setup fee plus cost of a DSL modem (3) twelve-month contract that can't move house with you is mandatory (BT again). However, deals going around are around £20/month.
Which ISP you use is almost irrelevant, because just about any ISP is more reliable than BT - almost all DSL hiccups in practice are BT's fault. AOL actually do one of the best deals - slow connection (256kbps) but no download cap.
And by the way, Wanadoo (formerly Freeserve) do £7.49/month for your first three months for FRIACO dialup. They claim to be IE-only, but the IE config file actually contains everything you need to know to set up the dialup yourself. That's how we did it, anyway.
