List of own numbers (Menu 4-5-3)
This function is a memory aid, which you can use to check your own
phone numbers if you need to do so.
Within this menu you can store, erase, edit, send, and print via IR
the the phone numbers assigned to your SIM card, if this is allowed
by the card.
The edits that you make here do not affect in any way the actual
subscriber number(s) of your SIM card.
