Our baby being air flighted to the hospital was also found in a text message.
So if I call him out on that, he could say, "oh it must be mystery guy trying to mess with me!"
I could easily check to see what is a real text from him or not by using my company's resources, however, I would be fired for looking up my own information or information not related to a customer. And I like my job, so..
I could have him call into phone carrier and give me permission to talk to the rep. I could talk them into how to find the information I would need to verify who sent what text message and if the phone was cloned or not.
