This message normally means that the unlock code (also known as network unlock code, network PIN or NCK code) has been entered incorrectly too many times and has therefore blocked the phone from being unlocked.
Most network providers such as EE, Vodafone, Three and O2 only provide you with an network unlock code and can not provide the code needed to unblock the phone if this code has been entered incorrectly.
