From what I have googled their are apps so someone can use your number to text someone else. This person that is receiving texts from my number is texting me back asking me to stop. I traced the number of the person texting me. This person is an ex girlfriend of a friend of mine but I HAVE NEVER MET HER and have no idea who she is other than her name from tracing her number. Can I find out who has stolen, using or whatever you want to call it and how would I go about that?
