We have had verizonwireless for the past 20+ years. Within the last 2 months my husbands phone will not make or receive calls while he is here at home. I have no problems making or receiving calls with my phone. At the time this started he had a Samsung Galaxy S5 and I have a Samsung Galaxy S9. I called for tech support about a month ago and re-did all the troubleshooting over that I had tried before the tech call and still the issue with his phone remained and was told the phone possibly needed a new SIM card. I made an appt at our local Verizon wireless store, went in and the person who helped me told me that a SIM card would do nothing and I just needed to upgrade the phone and was told "that's an old phone". They did swap out the old SIM card with a new and the phone did not perform any better. So I went online and ordered a refurbished Samsung Galaxy S8 for my husband to replace the S5. Got everything set up, went back to the store to have his number switched over. We thought this would be our answer and we are back to square one. My phone has no problem with making or taking calls and his will not even call my phone when I'm standing next to him. This is really frustrating. His phone worked perfect 2 months ago........what changed is what I would like to know?
