Change Your SIM card PIN
Setting a SIM card PIN helps protect against unauthorised use. This is different to your device lock code, which provides another level of security.
The default pin is 0000. For help to change it, see the ‘basic function’ menu in our device guides.
If your SIM PIN is entered 3 times incorrectly your device will ask you to enter your PUK (Personal Unlocking Key). You’ll find PUK help here.
