If you loved Light Phone, you should try this android app "Less Phone". It is brilliant.

If you want both smartphones and don't want to get distracted during office hours or private time.

Some were asking where to purchase these phones... You can purchase the Nokia 3310 at BestBuy. Decent phone for $60.

I considered going retro and getting a Nokia 3310, but 2G only was the show stopper.

They have a 3G model, I'm using right now! They also have a 4G 8110 "Bananaphone" that runs KaiOS, a sort of 'inbetween' smart-and-dumb phone.
