Owing mostly to TiVo's awful marketing, you've posted to the wrong forum. You're (possibly) looking for the TiVo Stream 4K forum; this forum is focused on the earlier TiVo Stream product, used for transcoding recorded and live content from a compatible TiVo DVR to mobile devices.I would like TIVO 4K. I currently have TIVO. Must I continue to pay TIVO after I set up 4K?
That said, the Stream 4K doesn't require a service plan. See: TiVo Service Plans and Policies: Essentials
