I am using an Iphone 4 originally bought and used in the USA on At&T. I jailbroke and unlocked the phone (using redsnow and ultrasnow) and am trying to use it during my few months on business here in New Zealand.
I bought a 2 Degrees data microsim card and have been unable to use it. When I have my phone on it will either say No Service or Invalid SIM. I have changed the APN settings but this did now fix the problem. Any other suggestions? Your help is greatly appreciated.
