I have a work iPhone6 thru Verizon and a personal iPhone6 with AT&T. I would like to be able to access my text message on my work iPhone from my personal iPhone. Without txt forwarding capabilities, the Verizon Messages app appears to be just the ticket. However, every time I try to input the passcode I received on my work phone, I get an error message. Literally a pop-up message box that only says "error" with an ok button to dismiss. Can anyone help?
