I used worldsim for a few trips and I also used to sell a few of them.
I have a few left and you are welcome to have one.
It can be activated and tested on line and while in Australia, generally calls are free to receive in most European countries and it comes with a UK number eg you can call the UK number from Australia at your rates and they will receive the call, say in Italy.
Have a look at worldsim.com
I have not checked for a while but I assume the calling rates have dropped a bit. I found them good for receiving calls but a bit expensive to make calls (a few years ago) but they were good for making bookings and as security. Most international roaming cards are the same tho.
They are really good as they cover all of Europe without having to change your number of chase up local prepaid cards.
They also have 5 pound credit when activated.
You get an online account for topups and so on. If you get one, activate from Australia before leaving, test by ringing UK number and it will divert to Australia. Your phone will need to be unlocked and preferably on the 900/2100 gsm 3g frequencies.
Data is a killer on all this types of accounts and I would definitely make sure that data is disabled on your phone before leaving, especially iphones.
If you want one after checking out the site whim me you mobile number and I will give you a call to answer any questions that I can.
