Ordinary cell phone service works so that the unique serial number in your phone (its ESN) is used by the cell phone service provider to identify who you are. The wireless service 'knows' that a particular phone's serial number is your phone and knows to send phone calls to that phone when someone dials your phone number. A GSM phone is not directly linked to you. Instead, it has a removable account card, called a SIM (subscriber information module) and this SIM has a unique serial number on it.

Your SIM card contacts will be automatically downloaded to your Personal Address Book when you use the SIM Phone Book Backup service. Any edits on the SIM card entries in your Personal Address Book will also send the updates to your SIM Phone Book Backup. In fact you can also change a non-SIM contact to SIM entry (up to maximum of 250 SIM entries) to have it uploaded to the SIM Phone Book Backup.

The SIM (Subscriber Identity Module) card (SIM Chip) is the brain of your handset. The SIM card is approximately the size of a credit card.

When inserted into a GSM handset, the SIM when activated by Cable & Wireless facilitates mobile service on a particular GSM network.

There is a whole process around this.
