SIM Card Lock

This extra bit of security allows you to lock your phone’s SIM card (the little card that lets you connect to your mobile phone provider).That way,no one can make phone calls without the PIN.

If you’d like to set this up,tap the Application tab,tap Settings,tap Security & location,and then tap SIM card lock.

The settings are rather basic:

• Enable Lock SIM card locks the SIM card.

• Change PIN code changes the PIN code.

Don’t you wish everything was so clearly labeled?

If you don’t know your SIM card PIN,you need to contact your mobile phone service provider.You can’t lock your SIM card without that PIN.

Note: You’ll still be able to make emergency calls (such as 911 in the United States).

Locking your SIM card won’t prevent anyone from accessing documents stored on your phone,so don’t rely on it to secure all your data.If you’re worried about someone accessing your data when you’re not in possession of your phone,use the screen lock function,discussed next.
