PIN
You may need a PIN (Personal Identity
Number) to activate the services in your
phone. The PIN is associated with your
SIM card, and not with the phone.
Your PIN is provided by your network
operator. When you enter your PIN,
each digit appears as *, unless your
PIN starts with the same digits as an
emergency number, for example 112.
This allows for emergency calls without
entering a PIN.
If you make a mistake while entering
your PIN, delete the number by
pressing .
If you enter the wrong PIN three times
in a row, the SIM card is blocked and
the message "PIN blocked" appears.
To unblock it, you need to enter your

more frequent re-charging. If talk time
