The subscriber identity module (SIM) card identifies a phone to a Global System for Mobile Communications (GSM) network. Most mobile phones companies use GSM networks, and therefore most mobiles phones use SIM cards. A SIM card can also be used to store a relatively small amount of data, including phone numbers from your address book. This can be useful if you are switching handsets because you just have to transfer the phone numbers to your SIM card and then place the SIM card in the new handset. In a BlackBerry phone, transferring phone numbers to a SIM card must be done one at a time and through the address book menu.
Instructions
1. Insert SIM card into your BlackBerry device by removing the back panel and the battery from its compartment. Slide the SIM card holder the unlock position and lift the latch up. Position your SIM card so that the gold contacts are face down and the notched end is facing right. Press the latch down and slide the SIM card holder to the lock position. Replace the battery and the back panel. Turn your BlackBerry phone if it doesn't automatically start up.
2. Press the menu button to go to the applications page. Click "Contacts" to open your BlackBerry address book.
3. Highlight the address entry that you want to transfer to your SIM card. Press the menu key. Click "Copy to SIM Phone Book" to finish the transfer. Repeat for each address book entry you want to transfer.
