Great Potential, page-6

I may have missed something in the presentation, but essentially what this means is that you can roam in another country like the USA for example and keep your Telstra sim card in your phone. Once you hit the ground you are automatically assigned a roaming number etc..

However does this not mean you are required to be on some kind of roaming internet connection as well. Im sure most of us know with players like optus and telstra that aint cheap to roam your 3g/4g anywhere. ( yes im just basing this on australian corporates )
Sure if you are connected to wireless somewhere like your hotel or office that becomes a non issue as its all done over VOIP. Surely the 3g/4g international roaming costs out weigh the charges for just roaming your mobile number ?

Cheers
