I am interested in signing up for your fibre broadband at £25 per month, but it is asking for a landline number and I don't have a landline because I use my mobile, I want to swap my sky broadband to yours.
If you have Sky broadband you have a phone number for the line. Its on your account details at sky.com. I have Sky and dont use a landline phone, but i still have a number. Its that number they need.
