For those travellers that have been stung by roaming charges before, please note that Woolworths has now started to offer special global roaming SIMs at a fraction of the cost of othe providers, with coverage in 230 countries. Cost is $29 for the SIM, and call rates vary from country to country but are all pretty reasonable. They can be purchased from most Woolworths stores and activated online in a matter of minutes.
(Thank you to the chaps at Blue Zoo for coming up with this solution for me).
