Got a text from this number saying "Hello, Karrie?"  When I asked who it was they didn't respond.

Got a text saying, "hola Nickole." and then nothing else.  No Nickole here...

Received a text from this number. It said. 'hi - (my name)'. I texted back (quien es?) The person responded (my phone is dieing - sorry)
