    What provider do you have?

    Does your SIM card work in other phones?

    Is the carrier network enabled to begin with?

    Hmm... Possible scenarios:

    1) You didn't unlock your phone but you think you did.
    2) Mobile network not activated.
    3) Wrong GSM band.
    4) SIM Card error??

    Even if BIS is not activated, you should still be able to make calls / send messages. If you can't even do these two, you are not even connected to the carrier network.
