Can I use my old iPhone to take/make calls like iPad does?
Not sure exactly how to ask the question because I don’t know what the technology is called.
I have an iPhone 13 that I use as my primary phone. I’d like to use my old iPhone 11 to take and receive calls much like I use my iPad does. I don’t want to activate the iPhone 11 I just want to use it like extension of a landline. Not even sure where to start.
