Good Morning Lisa-m-evans87,
Thanks for your message on our Community Forums and a very warm welcome to you!
Sorry to see you've been having issues with calling your home number from your Vodafone mobile.
Can you tell me if you've discuss the porting of the landline number with Sky at all? Can you also advise me if any other Vodafone mobile phones struggle to connect to your landline service, or is it just yours?
Kindest regards,
David_Bn
