SMS on MY PC

I have done that several times but I just did it again. I sent a SMS text to my laptop (Rickhart@cox.net) and also to my desktop (Rickhart@cox.net.) I also sent it to my laptop to my Google Mail (1easyputter@gmail.com) and neither my laptop or desktop received anything. I then did the same thing with my wifes iPhone with the same results, not received on laptop, desktop, and wifes iPad.

Hopeless cause…..It isn't going to work no matter what I do. I never realized just how much I used it, until it stopped working. Sort of buying all new phones to the tune of $1000.00, not going to happen, I have tried everything. I stopped at COX and Verionand  they both sent me a SMS from their e-mail computer like I have been doing and received them all fine. 

So it looks like it will either be COX or Verizon since T-Mobile doesn’t work and no viable answers
