by the way my sisters cell has some kind of app on it and she can see whos calling and block the number so you can probley find out what that is and use that :)
you can also set it up to where you can't recieve phone calls from blocked numbers..i know alot of my family done that..
do you mean *67? I dont think you can find out who is calling you just ignore whos calling you.
There's an app you can get where the number comes up as their actual number(:
i don't think you can , just ignore the call or screw with them back lmao.
