This is the featurephone (S40) and dumbphone (S30) set of operating systems that Nokia owns and uses on their many, many other devices. Despite zero technical relationship between these and Symbian/S60/S^3/etc. there is much overlap in documentation. It is worth looking at the Symbian section as well.

Nokia Asha is not an OS at all. It's a marketing name (like "Lumia") for "high end" featurephones. At launch, this was also sorta, kinda discussed as though it was an OS or GUI layer, but there was little difference between that and "normal" S40, and over time this has entirely disappeared of course. I think that it just evolved to what they now call Touch & Type.
