Yes. The phone is 'locked' using a computer program - by the carrier that the phone was originally supplied by. They only do this - so they recover the manufacturing costs of the 'free' handset from the first user. However - there are ways to unlock the phone so that it can be used on any network.

What is the purpose and benefits of an international cell phone?

Some cell phones are designed to use a Subscriber Identification Module (SIM) card, or microchip that stores subscriber data. The SIM card is issued by a carrier and provides cell service by activating any phone into which it is inserted. A locked phone, however, will only recognize a SIM card from a particular carrier. If the cell phone is unlocked, it will recognize a SIM card from any carrier. The "lock" is a software setting that keeps the cell phone "loyal" to one carrier.
