Access point name settings are not available for this user / Samsung A14 5G from Tracfone

Samsung A14 5G SM-S146VL from Tracfone (part of Verizon) was bought for cheap from QVC. Phone was unlocked after 2 months of service using the code received from Tracfone. US Mobile SIM card inserted. Calls and SMS work. Mobile data does not work. When I go to the APN settings it shows "Access Point Name settings are not available for this user". "Add" option is greyed out. "Reset to default" option under three dots is greyed out. So, it seems like Verizon prohibited using their phones with other carriers even after unlocking them? Any ways to solve this issue? NO root, BL not unlocked. Thank you!
