Welcome to Vodafone Community
I see your post has been moved to the Pay Monthly Board.
May I assume your definitely a Pay Monthly Customer ?
Can you then please confirm your account type and mobile phone model.
Have you looked in your myvodafone to toggle on Wifi calling and looked in your phones connection settings.
Calling Over Wi-Fi would only kick in if your network signal fails.
Some further help below.
Calling Over WiFi Set up.
Phone customer service on 191 or Live Chat.
Ask the agent to force the phone via sending an OTA configuration update that should provision your phone for Calling Over WiFi.
"Register for Vodafone Wi-Fi Calling.
Text the word CALLING to 97888
This is a free text which will add the service to your account.
You should receive the following confirmation text:
Thanks. We’ll add Wi-Fi Calling to your account in the next 24 hours and will let you know when you’re all set up.
If you’d like to discuss this with us, or if you have any other issues, you can find more info here or contact us
Once you receive the confirmation text, switch on Wi-Fi Calling in your settings
Go to Settings, scroll down and choose the Application icon
Choose Phone and scroll down until you see Wi-Fi Calling – select the box beside this option
A pop-up will appear asking you to confirm if you want to enable Wi-Fi Calling – tap OK"
