At one time you could download the code from the Internet free and do it yourself.Worth a look.If not there is usually a local market with a stall that sells or repairs mobile phones.they usually do it for £10.but worth searching the Internet for a free Code so that you can do it yourself.
Try a well known marketing site on line Several sites there. Got my RAZR unlocked via email for £5. They send the 'subsidy code' code to you to enter once you have the new card in, but they need the EMEI number for your phone that comes up when you press certain keys. Don't post any EMEI numbers on here though.
