Answer:
YOU CANT!! I figured that out today.. Even though Im getting harassing phone calls, because the number is restricted. I would have to change my phone number. Why do I have to do all this when someone is harassing me!? Im pissed off.. and no cell phone service has the ability to just block restricted calls. so pretty much my only option is to change my cell phone number. There should be no privacy act for phone numbers..!! lets just hope this creep doesnt come try to do something to me.
Answer
Customize your phone system.Create a preset list of contacts. Numbers not included in your list will be blocked or directed to your voicemail. This will help you limit incoming calls.
