My boss is taking a trip to the US with a colleauge(both from Australia). They will be taking their mobile phones with them. What calling code would they need to use within the US to call each other on their Australian numbers? Thanks
Thanks for your inquiry.
They would basically place calls as if calling from the US to Australia which is what happens in this case. Calls of this type are routed back to the country where the phone is registered and then redirected to the actual location of the phone.
