Although there are several types of “locks” that can apply to a phone, the most talked-about type is a carrier lock, also known as a SIM lock or subsidy lock. Many phones sold by carriers come “locked” to that carrier. A “locked” phone can only be used with that carrier; it cannot be used with another carrier’s service. (Not counting roaming.) This lock can usually be removed by entering a special code or numeric password. In some situations, some carriers will supply this code upon request by the customer; not all carriers will do this. There are also third-party companies that sell such codes, or other types of unlocking services.
