I had this shower thought earlier and I actually wanted to post it in that community. The name I came up with was SmartWalkman, but later I realized that Walkman is Sony specific, so I doubt other companies would’ve gone for that name, but I didn’t want to let this shower thought slip so here I am now asking you guys.
You must mean Flatrate? A term for a flat/fixed price with unrestricted volume (the default for home internet; mobile phone plans have variance).
I’m not aware of anything being called “flats” in German. Could be an abbreviation in circles though.
Yeah, flat is colloquial speech for Phone Flatrate. Flats being the plural.
