eXDee: I'd love to see a breakdown of roaming charges.
What percentage gets put down as the roaming providers cost, the local provider back home's cost, and then how much goes in their pockets each as straight profit.
I imagine the large charge and the majority of the money goes to the overseas provider providing the roaming service.
You forgot the 3rd party sitting in the middle (in many cases) - the provider of the roaming hub.
