Purchased Note8 directly from Samsung Jan 2018 and used on Verizon Prepaid network with access to all features till about May of 2019. Now phone works however I can't make changes to my account online, or access the app, add Travel Pass, it says SIM Card and Phone are not paired on website and app. I understand that as an unlocked phone it may not have access to all features but phone is performing poorly on Verizon network. Corp stores refuse to help pre-paid customer. One rep says you need a new SIM (already got one, issues remain), and another rep says that Samsung must not have reported my IMEI # to Verizon so my phone is not compatibile with network. Online checker says "Note8 is no longer compatibile with network, would you like to upgrade to a newer device?"
