A subsidy unlock code allows you to switch cell-phone service providers.
A Nokia cell phone may be "locked" when a user is unable to activate the phone with another service provider. A cell phone company may lock a phone so that only its service can be used with the phone. Unlocking a cell phone requires contacting the current service provider and obtaining a subsidy unlock code. This code allows you to use the phone with any cell-phone service provider. If AT&T provides the service on your Nokia phone, call them for your unlock code.
