Insert a fingernail, or a sharp object such as a pen, into the hole in the label
tray, then drag the tray outwards to view the IMEI number.

SIM card protection
The SIM card lock only protects your subscription. Your device will still work with a
new SIM card. If the SIM card lock is on, you have to enter a PIN (Personal Identity
Number). If you enter your PIN incorrectly more times than the maximum number of
attempts allowed, your SIM card will become blocked. You need to enter your PUK
(Personal Unblocking Key) and then a new PIN. Your PIN, PIN2 and PUK are supplied
by your network operator.
