    Hi all,

    I was wondering if somebody could please help me.

    I got an iphone 4 nearly 2 years ago in the UK, I then changed companies whilst over there, so I know it is not locked to a network.

    I have recently moved to Australia with my iPhone 4, but when I put an Australian sim card in the phone will not work and tells me to take the phone to my carrier. Unfortunately this is in the UK.

    I called a mobile phone unlock company that stated he cannot do it as it is different software.

    Is there anything I can do to unlock my iphone until I upgrade as I cannot do this for a few months until I am settled in with employment but love my iphone and would be lost without it.

    Any information would be muchly appreciated.

    Thanks :)

    Call the carrier the iPhone is locked to and ask them to unlock it.

    You said you changed carriers in the UK and used the same phone then it should be unlocked. Which carrier did you change from and to?

    If the phone is unlocked it should work with any carrier. I have never heard of a message on the phone that says take it to the carrier. If the phone was locked and you put a foreign SIM in it says Sim not recognized, or no SIM.

    I moved from 02 after some issues with them. I then used lebarra for a few weeks, then used 3 mobile for over a year.

    the message says,

    only compatible sim cards from a supported carrier may be used to activate iphone. Please insert sim card that came with your iphone or visit a carriers store to receive a replacement sim card.

    I do not have the original sim but and cannot visit their store.
