How do you secure iP4 if you put in a new SIM

[MrMister111]

Hi I'm about to change network providers. My current SIM has a code when I restart it. Great

I tested my new network providers SIM in, and my iP4 booted fine with no code required.

What I want to do is have my iP4 ask for a code if a different SIM is inserted, eg if it was pinched the SIM couldn't be used but the iP4 potentially could. Is there a way?

I know you can password your iP4 when you want to use it but I don't.

Cheers

Don't use just the sim lock!
