    Hi everyone,

    I am new to Blackberry & have bought a unlocked 9900. When I put my SIM card in it keeps saying please insert SIM card.

    I have checked the SIM card details in advanced settings & it says that Identity & Associations are all Disabled.

    Is the phone working?

    many thanks

    Is the SIM card put in correctly? Take out the battery and there is a little picture showing you which way the SIM card should be put it. Also what is your carrier? Depending on your carrier you may need a 9930.

    What carrier are you trying to use it with? Bizarre is right. It may just be placed incorrectly in the sim slot.
