How do I Copy Contacts between my Samsung S425G and the SIM Card?
Your mobile device utilizes a SIM card that can hold up to 250 contacts. To copy all your contacts to and from the SIM card press Menu > Contacts > SIM Management and select Copy Contacts to SIM or Copy Contacts from SIM. Check off which contacts you would like to copy or select All and select Copy. When copying from the phone to the SIM card some information may be lost.
Note: When viewing contacts, by default you are viewing them from the phone. To change viewing options, press Menu > Contacts > Contact Settings > View Contacts from > All. A SIM card icon to the immediate right of the contact name denotes that it is saved on the SIM card.
