It’s possible to get a landline when you have a fibre broadband package, even if it’s full fibre and doesn't use a phoneline to transport your data.  Getting a full-fibre broadband package that includes a landline may be a lot more expensive because you’ll need two separate cables and wires for both products.  If you’re getting FTTC fibre broadband, which still uses a phone line to transport data to your home, you may be able to get a landline for a bit cheaper.
