SIM & PIN
To gether with your sub scrip tion you will ob tain a 3- volt SIM
(Sub scriber Iden tity Mod ule) card. The SIM must be a dual
mode SIM card to op er ate as a dual mode phone. A sin -
gle mode SIM will only ac cess GSM 1900 net works.
The SIM card con tains a com puter chip that keeps track of
your phone number, the serv ices you have or dered from your
net work op era tor and your Phone Book in for ma tion, among
oth ers.
Your SIM card is sup plied with a se cu rity code or Per sonal
Iden tity Num ber (PIN), which you need in or der to gain ac -
cess to the net work. Your PIN may also be re quired when
you want to change set tings in your phone. Fur ther more,
some op era tors may have serv ices that re quire a sec ond PIN,
the PIN2. You will find your PIN (and PIN2) in the in for ma -
tion from your op era tor.
When you turn on your phone you may be prompted to en ter
your PIN if the PIN is activated. If the PIN is en tered in cor -
rectly three times in suc ces sion, the SIM card will be blocked.
If this hap pens you can un lock it by us ing your Per sonal Un -
block ing Key (PUK) code, which is also ob tained from your
op era tor. See chap ter " Se cu rity" .
You should be care ful with your PIN, since it is your pro tec -
tion against un au thor ized use of your phone and sub scrip -
tion.
