Unlock code by IMEI

     This is by far the most well unlock method, and involves sending the IMEI number to unlock code supplier and by using your unique IMEI number the unlock code will be found in an unlock codes database. You will receive the unlock code along with instructions how to insert it into your mobile phone and after inserting it your phone will be permanently unlocked.


The pros

-is a pretty easy method for most of the phones, just need to get your phone IMEI by typing *#06# and to insert the code for most phones just need to insert a sim from a different carrier and will ask you for the unlock code

-for some mobile phones like Blackberry, Lg, Alcatel, Pantech can be received in less than 12h hours and is not expensive also

-you will only need the mobile phone and maybe a sim from another carrier to do the unlock


The cons

-the unlock success rate is about 90% depends on phone and network (if a code is not working will be refunded after presenting a proof)

-will not work on hard locked phones, on which the unlock code has been inserted too many times or which have a software problem and do not accept the factory code; also you will not receive a refund if you receive the unlock code but cannot insert it because the phone is hard locked

-for some phones or networks, the unlock can take more than a few days and also have big prices
