I have both a Galaxy S4 and S4 Mini on Verizons network. Neither can send or receive texts. I have an unlimited everything on both phones. Do I need to turn anything on on the phones and if so how? Both have access to wifi and 4 G. Process - Open a contact phone number, type in a message and hit send. Everytime it comes up and tells me send failed would I like to try again. I've tried from a number of different locations around the state (MA) and it's always the same. Send Failed.
