What is a Locked Phone?
If a phone is described as locked, it can refer to several things. A keypad lock prevents a user from accidentally pressing the keys; for example, while the phone is in a pocket. A security lock, on the other hand, typically refers to the security that prevents an unauthorized user from using the phone, such as a 4-digit number or a pattern. Typically, when people talk about a locked phone, however, it means that you can only use it with a specific carrier.
Carriers sometimes lock phones to offer their customers high-end devices at a reduced cost. The customer gets the benefit of a high-end device but pays only a percentage of the retail price in exchange for signing a contract. Such a contract typically lasts for one- to two- years. This gives the carrier time to recoup the cost of the mobile device.
Unlocking a phone allows users to take advantage of cheap deals offered by various SIM cards. Phone unlocking is a legal procedure. And while it can sometimes be tricky, it can also be straightforward and performed for free.
