Sometimes you need to use a local SIM card when travelling in order to avoid roaming charges when making or receiving calls overseas. GeoSIM has introduced an easy and cheaper way: just use their product called the “SIM PIG“.

The “SIM PIG” is a SIM Card like chip that bypasses the network lock on mobile phones, and enabling any SIM card from any network to be used. This product can unlock the latest smart-phones such as iPhone, Windows Mobile devices, HTC, Nokia, Sony Ericsson, Blackberry and many more.

Unlike the traditional methods of unlocking a mobile phone is specific to that handset, with one SIM PIG you can unlock any number of handsets.
