Re: NOKIA 6600 UNLOCK CODE
If your phone is SIM locked and your insert a SIM from a network which the phone is not SIM locked to, you will receive the message "SIM rejected".
If this is the case, you can get an unlock code from this URL:
It is more likely that your phone is attempting to register on a network that does not allow your SIM. (i.e. trying to use a Cingular SIM to access, or roam on, T-Mobile's network).
To verify if this is the case, manually scan for networks and select the one you want. See if it is accepted (go to settings->networks->manual).
