I'm being harassed with private calls. The police & my cellphone company said they cant help me. I heard about *57, tried it, doesnt work. I also heard about adding an application on my phone that can trace private calls, but I dont know if there are requirements needed on my cell to make it work. I have a blackberry but I do not have a data plan (dont know if thats what I needed to begin with). Does anyone know ANY WAY POSSIBLE for me to trace these incoming private calls to my cell? I refuse to change my phone #. I want proof of who's doing this so I can legally file for a restraining order.
