GSM technology can work with 4 frequencies: 850/900/1800/1900 Mhz.
Some GSM phones support all the bands or frequencies, or just a couple. A dual band phone supports only two, usually 900/1900 or 850/1900. A tri-band phone supports three bands, either 850/1800/1900 or 900/1800/1900. A quad-band phone supports all GSM bands. Quad-band phones are able to work with any and all GSM service providers.
On the other hand, GSM service providers support just a subset of all the GSM bands available. Before buying a GSM phone, make sure the phone supports at least one of the bands that your GSM service provider supports. Contact your service provider Rogers, Fido, Cingular, T-Mobile.

The competing system is CDMA (Code Division Multiple Access). GSM and CDMA are not compatible systems. If a phone is designed for GSM, it will not be compatible with CDMA and vice-versa.

Q:
My GSM service provider does not have sim cards, why?
A sim card is a small flat rectangle plastic that contains a microchip. This microchips is the heart of your phone, it contains your phone number, your address book, and the necessary information for your phone to work. All sim cards look the same, but the microchip inside is different for every GSM service provider.

My Motorola’s dictionary is displaying a different language, how can I change it?
Bluetooth is a short-range wireless protocol that allows your phone to 'speak' with other devices in range, such as wireless headsets, hands-free car kits, and computers. It can be used for a wide array of applications- take a look at www.bluetooth.com for more information

The easiest way is to try and put a SIM card from a different service provider in your phone to see if it will accept it. If you get a message saying wrong card, enter subsidy code or SIM disabled then likely it's locked. For CDMA phones it's a little more difficult to tell.
By unlocking your phone you have the freedom of using your phone with other network providers as well as saving tons of money using a pay as you go card when visiting other countries.
