I have a Samsung Note 3. it was tested with both a Verizon and AT&T sim cards to make and take calls before I bought it. I received my sim from Verizon and was unable to make or take calls, but did have data and text service. I worked with support on the phone and they determined it was likely a problem with the sim card, so they sent me another one. I inserted that card and it would not activate on it's own, as I was told it would. I called support again they were able to activate, and again, data and text worked, but no phone. They looked on their back-end and said the phone was still not registering for some reason, even though it said activation was successful. They troubleshot with me for about 40 minutes with safe mode, and even a factory reset to no avail. We opened a ticket with tier 2 on the 27th, and was told I would be contacted within 24 hours. I did get a text, on the 28th that the ticket was being worked on and to expect an update within 24 hours. I got a text today, 24 hours and 5 minutes later, that I should wait another 48 hours for an update. This is going on 9 days with the same problem. Does anyone have anything they can suggest? I have also done all steps in the Verizon troubleshooter, from the site.
