Locking and protecting your device

IMEI number

Every device has a unique IMEI (International Mobile Equipment Identity) number. You

should keep a copy of this number. If your device is stolen, your network provider can

use your IMEI number to stop the device from accessing the network in your country.

To view your IMEI number

1

Detach the cover of the micro SIM card slot.

2

Place a fingernail under the right or left edge of the label tray, then drag the tray

outward to view your IMEI number.

You can also open the phone dialer on your device and enter 

*#06#

 to view the IMEI number.

To view your IMEI number in the device

1

From your Home screen, tap   .

2

Find and tap Settings > About phone > Status.

3

Scroll to IMEI to view the IMEI number.

SIM card protection

You can lock and unlock each SIM card that you use in your device with a PIN (Personal

Identity Number). When a SIM card is locked, the subscription linked to the card is

protected.
If you enter the PIN incorrectly more times than the maximum number of attempts

allowed, your SIM card will become blocked. You then need to enter your PUK (Personal

Unblocking Key) and a new PIN. Your PIN and PUK are supplied by your network

operator.

To lock a SIM card

1

From the Home screen, tap   .

2

Find and tap Settings > Security > Set up SIM card lock > Lock SIM card.

Enter the SIM card PIN and tap OK.
