Irish firm launches ‘global’ mobile phone

Hmmm… Cubic Telecom have come up with a SIM (called "MAXroam") that will be accepted as a local one where ever in the world you use it. They’re using SIP (VoIP) to back haul the call from the caller’s area to the destination, avoiding international call rates, so the total cost is that of a mobile call from the caller to a local number, and from a local number at the other end to the destination.

They’re also going to have phones with wi-fi, which, in conjunction with a free hotspot, will avoid one of the calls, instead connecting directly to their international SIP infrastructure.
