Does it work with a flip phone?

Basic calling works, but voice dialing and keypad dialing from the home phone do not. A cheap smartphone gives you everything.

Some features Basic calling works with a flip phone. The extra features do not.

On an old flip phone, the basic parts work: your home phone rings for incoming calls and the sound works. The extra features, like voice assistant and dialing from the home phone keypad, may not work.

You can answer an incoming call on the home phone, but you may need to dial from the flip phone itself, then pick up the home phone to talk.

Keep the flip phone on its own power and awake, not asleep, or its Bluetooth turns off. For every feature, the maker suggests a cheap iPhone or Android smartphone instead.
