I work for Verizon but not wireless so I don't know the answer to this. Does *57 work from a cell phone? *57 is call trace and if someone is pranking you or you are getting annoying calls, you press *57 and it traces to call to the police department but you have to do it immediately after that person calls you. It works from a landline but I'm not sure about wireless and they aren't open until the morning. Was just curious. Or...can I block certain numbers from calling all together? I've been getting pranked lately from a number I don't know. they speak very little english but know what I'm saying when I curse at them to stop calling. And they call at like midnight or later. It has to stop.
