My Caller ID show my mother's name while calling
I have my iPhone under a carrier (T-Mobile) account which is under my mothers name. Whenever I make a call to someone that does not have my contact, it shows my mothers name along with my number as if she was the one calling. We have nothing tying our phones together besides that we are under a family plan with the carrier. Why is this and how can I stop it?
