Galaxy Note20 Ultra 5G and inability to connect to Wi-Fi calling

[BS2020]

When I try to connect to Wi-Fi calling I get the error message "Invalid Token".

I tried the forcing by turning on airplane mode, I have smart Tudor loaded on my phone, and followed other suggestions.

I have no idea what Smart Tudor is tbh, but what you need to do is speak to your network provider and have them take a look. You can't force/hack wifi calling.

Firstly check if WiFi calling is available on you network, if yes then speak to you network provider and ask them enable it on your account.

Then have the send the latest config/apn to your phone

If you think you can lack a network provider in to giving you WiFi calling them you live in the movies not reality

Speak with your network provider as they have to enable it for you to use it, it's not something you can switch on yourself. Your provider will send you a code.
