An old friend said they received a text message from me, which I did not send. When I asked what number it came from, they gave me the number of an old land line that I had disconnected 3 or 4 years ago.
I called the number and it is still out of service. I texted the number and received an error message stating that the message could not be delivered to the non-wireless number.
The message they received was pertinent to our friendship, i.e. not something others would know about.
Is it possible the old number was hacked or more likely that they are not being truthful about the message they said they received?
