There are several databases are connected at here, through which you can generate the unlock code of Sony and Sony-Ericsson devices. Before placing the order, check that the device is asking for unlock code and attempts are left to enter the unlock code.
Since, the code comes from the database, we only need correct 15-digits IMEI. You can find the correct IMEI in settings or by just dialing *#06# as a phone number.
Before proceeding with payment, choose the correct service to unlock. If you need any help, let us know.
