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 specific carrier. If the mobile phone is unlocked, it will recognize a SIM card from any carrier.

From the viewpoint of the consumer, the practice of carriers locking phones and using proprietary settings defeats many of the benefits of SIM handsets. Ideally phones should be left unlocked, or at least unlocked after the initial contract expires..

The Unlocked Mobile phone Advantage:

The Solution is to get an Unlocked cell phone from Global Roaming, the advantage is that the third party unlocked phone should work equally well with any carrier that uses SIM cards.
