If you have contacts stored on your SIM card, you can copy them to your device. You can add more details to contacts that are stored on your device, such as alternative phone numbers, addresses, or a picture.
Select Menu > Contacts.
Select Options > SIM numbers > Copy all to phone.
Tip: If you now have a contact twice in your contacts list, select Options > Settings > Contacts to display, and clear the SIM memory check box.
