Thread: Unlocked iphone doesn't work with O2?

    Default Unlocked iphone doesn't work with O2?
    hi guys, i tried asking in the other forum but no getting much headway. (http://www.modmyi.com/forums/unlocki...t-another.html)

    just hoping to see if any of you guys have similar situation.

    i've a 1.1.2 OTB 8 GB (AT&T) iphone that's upgraded and unlocked with various pieces of software (ziphone, iliberty and winpwn) to 1.1.4

    it works with a SIM card from a Singapore carrier (Starhub) but when I insert an O2 Pay-as-You-Go (basically a prepaid SIM card), it says No SIM card installed no matter what I do. I tried all those unlocking software and it's jailbroken but just won't recognize the SIM card.

    If I re-insert the Singapore SIM card, it recognizes and works. Also, if I put the O2 SIM card to a Nokia phone, it works too. Just won't work when I insert the O2 SIM card into the iphone. Any help is greatly appreciated!

    Default Me too
    My prepay O2 sim didnt work in the iphone 1 my dad gave to me so i did all the unlocking and it still didnt see it - said NO SIM. I tried my sim in my dads Iphone 2 and it did see it. I then noticed that the shape of the chip on my sim and the shape of the chip on my dads sim was different, mine was kind of oval, his was square; maybe this is somethin to do with it ? Did you get yours sorted yet ?

    i upgraded my iphone to 2.1 from 1.1.4 3 months ago.I was reminded that when restoring from backup in itunes after unlock that you dont let itunes activate your iphone, as soon as restore is done from back up you exit itunes at the point where itunes says something like" leave iphone attached it will restart in 10 seconds".Dont let itunes restart iphone.Now any sim can be used.

    No.

    Boost mobile is not GSM. They operate on the Nextel Network which is IDEN.

    Or so I believe.
