I have an unlocked Galaxy S8 that I've used with Tracfone for some time and just switched to Verizon.
Everything works (phone, text, data) but I have two messages that won't go away.
The first is: "Phone not activated".
The other is: "Wifi calling, tap here to confirm or update emergency location information for wifi calling".
I have seen some suggest tuening wifi off and trying to activate with just data but this didnt work for me.
