The internal phonebook is able to save multiple phone numbers per contact name; however, your SIM card is only able to save one phone number per contact name. When you copy contacts from the phone book to the SIM card, one number is stored for each contact. If you want to store all numbers for a contact, you need to make three separate entries in the phone book before copying to SIM. For example, if you have 100 contacts and 2 numbers stored for each contact, the SIM card must be able to store 200 entries. When you copy contacts from a SIM card to the phone book, each position on the SIM card is saved as a separate contact. You have to re-edit your contacts in case you want to have multiple phone numbers under one name.
