Unusual iMessage received from my mom, who wasn't aware she sent it I received a iMessage via my mom's locked iPhone 4 while simultaneously calling her.  I stated I just received a message from you. She was confused because she doesn't use or know how to use this feature.

The content said "Can't talk now - On my way.".  I sent her a screenshot of this verbage to which I was referring to.  She allowed another family with more experience of iPhone to investigate.  They had no record or proof on their end of what I had sent but the rest of the message thread was identical. 

How can I receive a random message seemingly via my mom's telephone number that she did not send?  Can we be part of someone else's spying on and unlocked phone? 

I am extremely confused.  I called AT&amp;T and Apple and neither could help me.
Check the following:


Settings
Phone
Click the third line (free translated) "Answer with text message"
The exact text you received is right there.


If you have a running phone call, your screen will turn black once the sensor will notice the darkness of your face being close to it.

Once you click on your phone during an incoming call, you can decline the call and answer with one of the messages explained above.

This has nothing to do with spying and hacking.
