(2026年 6月 29日 20時 14分 追加) [ULTRA RARE / Early One-Seg Mobile TV Era] au by KDDI W33SA by SANYO Store Demo Hot Mockup Mint Condition & Functional
This is an extremely rare collector’s item: an au by KDDI W33SA by SANYO store demonstration “Hot Mockup,” believed to have been used for live in-store demonstration purposes around the time of the model’s release in December 2005.
The W33SA is a historically important model in Japanese mobile phone history, widely known as one of the earliest and most symbolic One-Seg mobile TV phones. It represents the moment when Japanese mobile phones began integrating terrestrial digital TV reception, FM radio, music playback, and multimedia functions into a single handset.
Unlike ordinary non-functional dummy phones, often called “Cold Mockups,” this unit powers on and operates as a live demonstration device. It is a highly unusual surviving example of a functional store demo handset from the mid-2000s Japanese mobile phone era.
