Best single member Unlimited Phone Plan

Hello, I am curious to know what you guys think is the best single person unlimited data phone plan.

I have a paid off iPhone 14 Pro Max and depending on the trade in won’t be opposed to trade in for the new iPhone. I need reliable service and of course unlimited data. I heard vision by Verizon is good but figured I’d ask the sub there thoughts! I am currently with AT&T on a family plan but shopping around I see that there are much better single person plans that can be cheaper than the portion I pay with the family plan.

Thank you 🙂
