Managing the Phone Book

When do I use these numbers?
Group the numbers on the list according to when 
you use them. Most people call a different set of 
numbers during the day than they do in the evening 
and on weekends. You can switch One-Touch 
dialing to your phone’s memory (locations 1–9), your 
SIM card’s memory (locations 101–109), or to your 
Fixed Dial List (locations 1–9). Store your evening 
and weekend numbers on one type of memory and 
your daytime numbers on another.
Which numbers do I need to keep 
secure?
Tip: 
 If you 
have many 
entries, group 
them in 
blocks of ten 
to make them 
easier to find.
Use your SIM card to store the numbers you need to 
keep secure, like the numbers of friends and family 
members. Because your SIM card is the size of a 
credit card, you can easily keep it securely in your 
wallet when you aren’t using it. If you wish, you can 
even require a PIN code every time your SIM card is 
inserted into 
any phone. (To deactivate your PIN 
code, see page 142.) Store more public numbers, 
like business associates and travel agents in your 
phone’s memory.
