We have two skype 3G moblies and have gone from £65 to £20 per month you can only use it to and from Oz, Ireland, Italy, the UK at the moment but other countries are being added to the system, to use skype free on payasugo you have to add £10 per month to get free skype to skype service but the £10 never expires you also have the internet, tv, plus a 2.0 meg camera with phone.
I paid £80 for the two on a deal from a 3G shop better than £49.99 each service is great too.
