📰 Why this phone matters: The Nokia 6788i (RM-636) is a China-only smartphone released in 2010, designed specifically for China Mobile’s TD-SCDMA/GSM dual-mode network. Constructed around a solid metal frame with metallic accent panels, the 6788i features a premium sliding mechanism and rugged build quality rarely found in region-exclusive Nokia devices.
This model was created during Nokia’s short-lived TD-SCDMA development phase, and because the technology existed only in China, the 6788i never reached the eur;opean or international market. Production volumes were extremely limited, and nearly all units stayed within China Mobile’s distribution channels – making surviving examples extremely rare for collectors worldwide.
The phone runs a China-specific firmware package and represents a unique combination of Nokia industrial design, metal-slider craftsmanship, and a specialized 3G technology Nokia used only once.
This particular unit is BNIB (Brand New In Box) – an exceptionally difficult condition to find for any China-exclusive Nokia, elevating it to true museum-grade status within any serious Nokia collection.
