This lock only protects your subscription. Your phone will
work with a new SIM card. If the lock is on, you have to enter
a PIN.
The PIN2 is required to access some network services, and
your SIM card must support these services.
If you enter your PIN incorrectly three times in a row, the SIM
card is blocked and you need to enter your PUK (Personal
Unblocking Key). Your PIN, PIN2 and PUK are supplied by
your network operator.
To unblock your SIM card
1 When PIN blocked. Enter PUK: appears, enter your
PUK and select OK.
2 Enter a new four-to-eight-digit PIN and select OK.
3 Re-enter the new PIN and select OK.
To turn on the SIM card lock

management > Security > Phone and SIM card > PIN
request > On.
