    Dear Mira,

    Make sure to insert the code in the right place. I suspect that you are using the codes received from us instead of the SIM Pin. 

    The SIM Pin is a user-defined four-digit passcode used whenever you turn on the phone to access the network. This will prevent someone from making calls with your SIM without your permission. Some carriers provide SIM cards with a default SIM PIN already enabled. Each network has a default SIM Pin (e.g. 1111, 1234, 0000). You can change this default SIM Pin anytime.

    Normaly after you insert the right SIM Pin your phone should ask for the network unlocking code.

    Please contact our support department via for more info.
