NMS sensed that there was a SIM card change when there was no such activity. then I was given a message that I could retrieve a passcode by going to https://mobilesecurity.norton.com. Unfortunately I have Norton's VIP access and the six digit code is sent to my locked phone. I went on the Norton's chat support line to see If they had a solution, if they could call someone tho authorise a one time use passcode or VIP access code that I could retrieve the passcode.. No go. I know that I am not the first who have had this happen to.
