Have a Samsung S20 FE 5G on Vodafone (UK) with WiFi Calling enabled at network provider end but no option is showing up for me to enable it on phone. I have tried all the guides I can find online but no matter where I look the option is not there. I have reset network settings, turned it off and on again at network end and done same with phone. I'm losing the will to live with these now. Please someone help.
Update: I have changed my wife over to BT mobile. WiFi calling came up straight away. Its therefore a Vodafone problem in my opinion. They're not interested in any help. So I soon will also be leaving.
