6 Phone Book
6.7 Copy Phone book
Use this option to copy records from your SIM card to your phone and viceversa.
Select the Copy from SIM Card to Phone book (1) option to copy the contacts stored on your SIM card into the phone’s memory. This action will overwrite all existing entries in the phone’s memory, so the phone will ask for confirmation that you really do want to perform this action. Press Accept 
to go through with the copy or Cancel 
to abort the action.
Select the Copy Phone book to SIM Card (2) to copy the contacts stored in the phone’s memory to the free spaces in your SIM card.
In both cases, the progress of the copy will be indicated with tones, and messages saying either Phone book copied or SIM copied.
