a question for the girls?

this has puzzled me for a while now. why would a woman assign a ring tone to a text from what appears to be the cell carrier? the ring tone assigned is ***** alert
now why would a woman do that?

TO GIVE SOMEONE A RING TONE IS JUST TO MAKE IT EASY WHEN SOMEONE CALLS OR WITH ME I GET HAPPY WHEN I HEAR THAT SONG COME ON AND ITS THAT ONE CALLING
