Always one for a bargain, I decided to plunk down some dollars and give cellular callback a go. If you're not familiar with the concept here's roughly how it goes.

You initiate a call by making a request of a service centre... you do this by either using a piece of software if you are on your PC, or by txt messaging the number you want to call to a certain short code or phone number. Here's the slide deck...

The 'system' then rings you back on your mobile and, once you answer, rings the other party to the conversation for you... A few hoops to jump through, but, talk about CHEAP phone calls. US 5c per 30 seconds to all of the major countries.... and that's from your mobile. Voice quality is excellent- if it's using VOIP it's certainly not problematic for quality.

It's sold via some pyramid scheme, but, to be honest it makes for cheap phone calls so it got my $$$. Come join my pyramid- http://www.1cellnet.com/cauld - well it's not a pyramid it some other sort of cell based, unlimied level paying... blah blah blah.... I've never been much of a fan of multilevel marketing (Away and all that garb) but it does make for cheap airtime, something I go through a lot of! Hopefully I might be able to move down a Vodafone Daytime minutes plan or two.... I think @ US10c per minute it works out just under 50% of the normal Vodafone price per minute.
