Yes, I believe there is one in development by these guys: https://www.cloakedwireless.com/

Fixing mobile networks is phase 1 of their journey. The next phase will be to replace Helium by allowing residential users to provide 5G connections and get paid in lightning.

Linked to this will be the ability to route those connections over lightning in a similar way to Tor.

I'm rooting for them!

I'd also like to see an app where you can share your bandwidth to anyone in the vicinity, anonymously, and get paid in sats.
