There's also just an absolutely bonkers number of functional second hand devices out there. A lot of them make their way to Africa as phones people use (and the Chinese repair and refurbishmenr business is huge and a volume business).

There are charities which will also give away phones because for a homeless person a usable phone is quite valuable because it makes it possible to do things like apply for jobs, find services etc. (even if you're just surfing cafe wifi).
