Most unlock codes for phones are found by accessing a database where most of the unlock codes are kept. These codes get added to the various databases by the manufacturer after the phone is locked.
When an order is placed with us we conduct a search through our network of suppliers of the available databases, looking for the code(s) relating to your phone. This is done by using the IMEI of the phone (found by typing in *#06# on the phone itself), and sometimes the name of the network that the phone is locked to. Therefore, it is vital that the IMEI of the phone is entered correctly on the order form to avoid receiving an unlock code for a completely different handset.
There are instances when an unlock code cannot be found for a handset. The most common cause of this is that the unlock code hasn’t yet been uploaded to the databases by the manufacturer and therefore we aren’t yet able to supply it. If this happens we automatically refund the customer once the searches have been completed, notifying them that no unlock code could be found. At our most recent reading, we were able to supply unlock codes for 94% of orders that came through to us, highlighting how rare this is.
Some unlock codes are however created by using programmes designed to understand what the unlock code for a phone would be. Unlock codes for BlackBerry handsets for instance are often found by plugging the phones information (IMEI and either PRD or MEP) into a software that then displays the code for that particular handset. For ease of the customers, we initially only ask for the PRD of the BlackBerry handset because this is easy for them to find. However, sometimes the software doesn’t recognise the PRD and the MEP is needed instead. When this occurs we send out the instructions to find the BlackBerry MEP easily, so the absolutely correct unlock codes can be found and supplied.
