I am fairly tech savy. I am in the USA. I have a NEW Samsung s20 Ultra 5G, unlocked dual SIM phone, Model SM-G9880.
I want make audio calls via wifi. I am connected to 2.4GHz Wifi and can browse the internet on the phone.
Wifi is turned on in Settings > Connections > Wi-Fi Calling. BUT, I have an error message in the Wifi settings; "ER082 - Unable to connect or generic error message or T-Mobile approved vendor handling" So I googled the error message and found nothing relevant. I do not understand the error's meaning.
OS is up to date.
Wifi calling not working. I rebooted, rechecked settings. Wifi is on. Power saving is off. Data saver is off too.
Developer mode is on.
Nothing I do will allow me to make a Wifi Call. When I try to make a WiFi call it hangs up immeadiatly after dialing.
Now do not please tell me I need to use a SIM card.
I should be able to make Wifi calls. I think I am missing something.
Please help.

You may need to contact your network provider so that they can push an OTA setting to provision the use of Calling Over Wi-Fi.
If your network using a Network App also make sure it's activated in there.
Calling Over Wi-Fi usually only kicks in if there is zero network connection. Try turning Flight Mode On.

The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "

Thanks. This is more help than I got from two hours on the phone with Samsung. Samsung kept telling me to call my cable internet provider.
I have no SIM and no network provider. This is an international unlocked phone not a network phone. This is why I need Wifi calling.
Airplane mode did not help. It told me to turn airplane mode off to make a WiFi call.
