Most carriers only supply service to a particular country or area; when traveling outside the coverage zone, the mobile phone user will have to "roam" on another carrier's network, which often comes with a high fee.

To avoid roaming fees, a person can buy a SIM card from a local carrier at his destination and insert it, preserving all his existing phone settings but getting a new number and a local calling plan.

This contrasts with a locked phone, which is bound to a specific cell phone service provider (or carrier) network with software settings, and is typically offered with a contract when someone starts mobile service.

One advantage to buying an unlocked cell phone is the ability to buy almost any GSM (Global System for Mobile Communications) phone, rather than being restricted to a limited selection offered by a specific carrier.

No matter which carrier makes the card, the phone will be able to recognize it and send voice and data over the network.One way to get a phone without proprietary settings is to buy it new from a third party vendor in its original, unlocked state.Third party services are also available to unlock a person's cell phone for a fee, usually by attaching it to a special piece of hardware specially designed for this purpose.For example, in South America, the 850 MHz band is in common use, but others may not be available.It is advisable to check on which bands the phone uses, and which bands are available in given travel destinations.
