All you have to do is take your SIM card, insert it & restore the data. In this way, your names & numbers are ready to be used in a matter of seconds. Also with the SIM Tools the user can edit the details of the data via the LCD screen. Once the SIM Tools has downloaded the data into its memory the SIM card can then be removed.
