Коды разблокировки мобильных телефонов: законность и методы

The term, Subsidy Password, is used by Motorola and other handset manufacturers to refer to the 8 digit code (or 16 digit code for phones such as the Motorola K1) unlock code necessary to remove the operator lock (also known as subsidy lock) from cell phones. This code is randomly assigned to individual cell phones by the OEM on request of the mobile service operator and prevents the use of a particular phone on a cellular network other than that to which the phone was originally sold.

As a result of the lack of open access to the Subsidy Password database, a number of online services have grown around providing alternative unlocking software. The methods used to unlock cell phones vary although most involve reading the code from the phone and resetting it.

Network carriers will sometimes agree to unlock their customers' phones upon request. While one could consider that the Digital Millennium Copyright Act brings the legality of such applications under question in the United States, recent legal cases such as Lexmark Int'l v. Static Control Components have confirmed that the use of software to reprogram such phones is not illegal. This is particularly true since unlocking applications increases compatibility with alternative networks, promotes positive competition and allows customers with greater freedom to use the phones that they own. In 2010, the Librarian of Congress exempted unlocking phones from the DMCA.

There are no legal prohibitions to unlocking in the United Kingdom or Canada.
