Reports are additional security measures which prevent the phone being used normally and are not removed by unlocking the phone. If your Alcatel has been reported stolen, lost or due to outstanding bills, you should contact the network provider to which the phone is locked to remove the blocking. You can still unlock your phone, you just won’t be able to use it until it has been removed from the blacklist.
