Sorry d_fisher, but that's not correct.
First, your phone number - the one that's displayed when you make a call - is actually stored on the SIM card. I discovered this when I got a new SIM and had no number displayed. On my (then) 7100c (Cingular), under Settings --> Options --> Advanced Options, SIM Card
. There, when you click the wheel, you can edit your phone number. I don't know what else that number is used for - like if it's used for Caller ID, etc.
Second, you can have SMS Messages stored on the SIM card. Settings --> Options --> SMS
, you can set Leave Messages On SIM Card
Third, in the Address Book
, you can view the SMS Phone Book
. Click the wheel and select SMS Phone Book
. This is a good place to store critical / emergency contact numbers since they're unlikely to get wiped. When viewing a contact, go to a phone number field, click the wheel and the first item on the menu should be Copy to SMS Phone Book
. Unfortunately, the name field is very short.
