Why Are Some Phones Locked And Unlocked

Executive summary about Unlocked Phones by Victor Epand and Terry Price

The term GSM means – Global System for Mobile Communications. It is the most popular standard for mobile phones in the world. Like other cellular standards GSM allows network operators to offer roaming services which mean subscribers can use their phones all over the world.

Now to answer your other question, with respect to locked and unlocked phones. A phone is locked when it is attached to network. The network it will lock unto will depend on the SIM card you put into the phone. For example if you put a AT&T sim in an unlocked phone then it will work on the AT&T network. In the same way if you put a NEXTEL SIM card in an unlocked phone then it will work on the NEXTEL network.

However if the phone is locked to a particular network, like say for example AT&T then changing the SIM card in the phone to another SIM card from another network such as NEXTEL will not work. This is because the phone is locked unto to AT&T network and as such will not work on any other network.
