Hi guys, How do i create a password for that stops other sim cards being used in my phone? Obviously i have a sim password that i need to enter whenever i turn on my phone but iam looking for the option to create a password so that whenever/if another sim is put in my phone, the user will need a password ? This is NOT the same as the password locked to the actual sim!! I had this on almost every past phone but cant find it on the htc one, I can create a password for my own sim but thats it!!
