By signing up with Rebtel via easyMobile, users will be able to make cheap international calls over mobile VoIP using “any mobile phone, over any UK network”, according to the companies. Those signing up will pay for a local call through their operator and then a per minute charge on top for the Rebtel service – 1.3p a minute if you’re calling an Aussie landline, for example, and 10p a minute for a mobile Down Under.

The service looks a distinctly promising one – more than anything else, it looks simple to use and there’s no sign up or software downloads to put people off. We’ll be watching this one with interest.
