Verde623, my scenario was identical to yours; text said: Hi Kay, then when I replied saying who is this, I got another message saying 'my iPhone is about to die'. Then I text back again, saying 'who is this?'. I got smart the final time and said: "My name is not Kay, so you must have texted the wrong person'. Didn't get another text from them, so I hope they leave me alone. Wish I knew how to block unwanted text messages (my android phone can block callers, but not text messages). Hate these stupid people!!!
