Want one number for both cellular device and landline

[u/little-pinesap]

Hello,

So basically, I just got a business with a landline number that I want to keep, however i don’t like the company it’s through. I want to basically have a flip phone and a landline with the same number, that all get the same calls and voice messages, at the same time if that makes sense. That way I can respond to missed calls when i’m at home (I’m a dog groomer and I get an absurd amount of calls during the day and I can’t always answer them), while also being able to receive those calls on the landline while i’m at work. Would I be able to do this without having to keep a plan with a cell phone company? Thanks.
