Re-programming more commonly known as unblocking is an illegal activity and not to be confused with unlocking.
When it is first made each phone is allocated a unique electronic serial number, which will generally stay with the phone for its working life. When a lost or stolen phone is blocked the phone is prevented from working.
Each time you use a mobile phone the signal is checked against a database of blocked numbers. If the database recognises your phone as having been blocked it won’t allow it to work.
When a mobile phone is “unblocked” unscrupulous individuals change the IMEI number and make it work again. This practice is illegal and only the manufacturers are allowed to alter it.
Unblocking mobile phones is a criminal offence and carries custodial sentences. It is even an offence to simply offer to unblock or reprogram a phone. The legislation is detailed below:
Mobile Telephones (Re-Programming) Act 2002
The Mobile Telephones (Re-Programming) Act 2002 made provisions to prevent the re-programming of mobile telephones this involves changing the 'unique device identifier' which is the international equipment identification (IMEI ) number - i.e. the unique serial number of the phone.

- he is the manufacturer of the device, or
- he does the act mentioned in subsection (1) with the written consent of the manufacturer of the device.
Notes:
- See also section 2 which provides offences relating to the possession and supply of articles to be used for re-programming.
- Section 62 of the Violent Crime Reduction Act 2006 increased the categories of persons committing offences under section 1 of the Act. Some of the offences contained within section 1 are not dependent on re-programming actually taking place.
Section 2 of the Mobile Telephones (Re-Programming) Act 2002 provides offences relating to the possession or supply of equipment for reprogramming mobile telephones:
2(1) A person commits an offence if:
