Normally we are talking about "unlocked" in regards to devices with a SIM card reader. THe device will have started out as a device locked to a certain mobile phone operator and through manipulations it has been unlocked. In essence meaning that it now can be used on any network with a SIM card from any operator.

A phone which gets free from sim lock / carrier lock is known as carrier unlocked phone .

Unlocking process:

The process of removing SIM lock from your phone is known as "Unlocking" ." Sim lock "indicates that the  current Network provider restricts our phone to use with other countries. For example: Consider you have an iPhone 4 which is locked to o2 UK . Unexpectedly, you want to switch over from UK to Australia . At that situation, your phone gets locked to particular network (o2). During that time, you need to unlock it to use your iPhone with Australia or other countries. You can get unlocking service from your Network provider/use factory unlocking method/get Remote unlocking method from any of the third-party service providers like  to unlock your iPhone 4. Not only US, all the network providers lock the SIM to work with different countries .We can't use it without unlock it. This is the process of SIM lock.
