Wi-Fi calling billing

[Giraffe]

How is this service charged?

My mobile service is with Smarty. My broadband and landline calls are with TalkTalk.

Thanks

This should make it clear:

All calls are listed and charged according to your package with your smartphone provider. 

You should see a list of itemised calls with your billing from Smarty, @Giraffe.

Not with Talktalk.
