Truphone, a very useful and effective mobile calling service I’ve written about many times before, is announcing the availability of their Truphone Anywhere service in Australia.  The new partnership and availability down under is via a partnership with Optus, a Australian mobile network operator.

Truphone Anywhere is a unique service where a person can buy a SIM to use their unlocked mobile phone in more than one country, without expensive mobile roaming fees.

With the addition of Australia, Truphone Anywhere now works in the United States, United Kingdom, and Australia.

This is good news if you’re an international traveler or business person.  I would keep an eye out for more announcements soon – probably centered around adding more western European countries to the list of Truphone Anywhere geographies.
