I thought I would let you know that my phone is fixed! The Verizon Wireless tech support person that has been helping me via phone called me today and said that the "escalated" tech support people thought it must be the Sim card. She suggested I go to a corporate Verizon Wireless store and have them replace the Sim card to see if that fixed the problem. So, I did that. The technician in the store told me that most likely it was NOT the Sim card, but that she would replace it just in case. Anyway, she replaced the Sim card and changed some settings on the voice mail and VOILA!, it works. I now have visual voice mail back and everything seems to be working just fine. I don't know what she did, but next time, I won't wait for the telephone support people to figure out a problem if they can't fix it right away. I'll go to the store and, specifically, I would ask for the same technician that helped me tonight. I know that others on this forum have not had such good luck with an in-store technician, but, perhaps they didn't go to a corporate Verizon Wireless location. I don't know if that is the key or if I was just lucky enough to get a knowledgeable technician. Good luck to anyone else with this problem, or any other phone problem.
