Who I have the same questioned this topic

I just had an irate voice mail call from a total stranger saying to stop sending her text messages.  I am unaware of sending her any.  Apparently my text messages sent to my daughter's phone also get sent to this person without my knowing.  My daughter receives my messages no problem.  Is this a Verizon system issue, firmware issue, or other?  I'm stumped. My daughter has a Droid Bionic, and my phone is a LG Octane.  I can't completely tell, but it may be happening when she texts me and I reply back.  Can this be a compatibility issue or something I can change on my side?  Could it be something simple like I didn't have her area code (same as my local area code) entered in my phone?
