Can you use Pinwheel phone without subscription?

I'm curious, is it possible to utilize the Pinwheel phone without having to sign up for a subscription plan? It's a question that's been lingering in my mind, as I'm always looking for ways to save on monthly costs while still enjoying the convenience of a smartphone. So, could you please clarify if Pinwheel offers a subscription-free option or if there's a workaround that allows users to bypass the need for a subscription plan? I'd greatly appreciate your insights on this matter.
