What is that a cell phone is unlocked?

An unlocked cell phone can be used with any company, without having to be tied to a specific plan. You can unlock your phone to use it with another company, or you can buy a cell phone unlocked on the Internet if you want to change your phone without having to go to the Agency. The purchase process and the use of a cell phone unlocked is legal and relatively simple in United States. Unlocked phones are more common in Western Europe.

You also have the freedom to use any unlocked phone with the phone company that is compatible. These phones can be used internationally to replacing the SIM card with a new one from the country you’re visiting, allowing you to reduce the costs of international calls when you are abroad.

Unlocked phones tend to be more expensive than people shopping with a contract of a company phone, sometimes two or three times more. Due to the few companies that use GSM, even with a cell phone unlocked, your options are relatively limited in the United States. Some phones have features that are only available with some telephone companies, and may not work when the phone is unlocked and used with another company.
