GSM Mobile Phone Guide

Mobile phones have become an inherent part of our lives. The market is flooded with thousands of mobile phones offering various benefits and features. It is however important to know the technology platform you are willing to choose you buy a phone.
GSM (Global System for Mobile Communications) is the leading mobile technology, which is renowned for its reliability and multi-tasking features. GSM offers high-end functions and tasks like express speed data transfer and instant fax & voice mail. You can also use features like paging and short message service. GSM technology offers customers seamless call privacy and full-proof secure communication.

The best part about buying a GSM enabled phone is that users can call anywhere around the world as long as they are connected to a GSM network. Nevertheless, there are few points to remember while buying a GSM handset. GSM operates in different bands and frequencies around the world. For example in Europe, Asia, Africa and Middle East, the mobile phone networks operate in 900MHz and 1800MHz frequencies. For other countries like North America and South America the GSM networks operate in 850MHz and 1900 MHz band. So, before you travel inabroad just ensure that your phone is capable of operating in the band available in that particular destination. Mobile phones operate under the following bands:

Dual Band – Dual band phones only operate in 900MHz and 1800MHz bandwidth, which means if you are travelling to North America, these phones will not be operational as the service providers do not provide this specific bandwidth.
Tri Band – Tri Band phones are equipped to operate in 900MHz, 1800MHz and 1900MHz band, which means you can use these phones in selected areas of North America except areas, which require 850MHz.
Quad Band – This is the best mobile phone to buy as it capable of working under any band therefore you can travel anywhere around the world on any GSM service providers or networks.
The SIM in the GSM

The SIM (Subscriber Information Module) card is like the heart and soul of your mobile phone. It includes the personal information of a subscriber and the user’s customised phone settings. It gives the identity to the subscriber in the form of a phone number, and data transfer in order for the subscriber to use the phone. This card is completely transferable from one phone to the other without changing the settings of the phone.
GSM is a revolutionary technology, which has led to other innovations in mobile technology like Bluetooth and EDGE services. The latest mobile handsets offer GPRS or Global Packet Radio Service, which enables high-speed data transfer in a matter of seconds.

No matter how important mobile phones are, one must ensure to have basic knowledge of what they are getting into. Therefore if you plan to pick up a GSM handset keep all these factors in mind.
