Overview: iPhone 3G Unlocking
The iPhone 3G must be unlocked using a "piggyback" SIM, a very thin (0.1mm) SIM card that you simply slide over the provider SIM that you want to use. The combined SIM effectively fools the handset into thinking that the original SIM is intact, allowing you to use your phone with any SIM card from any network.
Our service is plug and play, allowing you to quickly and easily unlock your iPhone 3G from any network!
