4Call Barring To Block Calls
The call barring facility allows you to block both incoming and outgoing calls on your phone. Call barring is a paid facility but just in case you have it enabled on your phone plan, then hers a code to activate the facility immediately without having to search for it. Enter *33*PIN# to enable the facility and again #33*PIN# to disable it. These are among the coolest codes hidden in your iPhone to improve functionality.
