SIM card
The SIM (Subscriber Identity Module)
card, which you get from your network
operator, contains information about
your subscription. Always turn off your
phone and detach the charger before
you insert or remove the SIM card.
You can save contacts on the SIM card
before you remove it from your phone.
See To copy names and numbers to the
SIM card on page 19.
PIN
You may need a PIN (Personal
Identification Number) to activate the
services in your phone. Your PIN is
supplied by your network operator.
Each PIN digit appears as *, unless it
starts with emergency number digits,
for example, 112 or 911. You can see
and call an emergency number
without entering a PIN.
6 Getting started
If you enter the wrong PIN three times in
a row, the SIM card is blocked. See SIM
card lock on page 59.
You may be asked to register your phone
at Sony Ericsson. If you accept to
register your phone, no personal data,
such as your phone number, will be
transferred to or processed by
Sony Ericsson.
