Started Texting my baby mama saying I was dating someone else now. Totally don't know why considering my baby mama has a boyfriend for over a year now. Apparently anyone can get a hold of fake numbers and text from them

This person has problems... They text my ex husband all the time saying I'm with someone else.

do you have any affiliation with gwinnett county?

My daughter has received text messages both personal and bullying in nature from 770-203-1187. The carrier is BellSouth Telecommunications, which appears to be linked to AT&T. Both my carrier, Verizon, and AT&T have not found a solution. When the number is called it states "Your party is not answering. Please try your call later." The numbers I have tried for Bellsouth do not answer. Is there a way to find out who sent the messages?

Might consider a call-blocker and do not pick up on calls you do not recognize.
