Samsung's long-rumored tri-fold smartphone has surfaced again — this time in the Bluetooth SIG database — suggesting the device may be closer to an official debut than many expected.
Bluetooth listing sheds light on global plans
The Bluetooth SIG entry lists multiple model numbers: SM-D6390, SM-D639N, SM-D639U, SM-D639U1 and SM-D639B. That variety is telling. When Samsung files different SKUs, it typically signals regional variants tailored for markets such as North America, China and Korea, rather than a narrow, limited release.
Why the model codes matter
Tech enthusiasts will recognize the pattern: the suffixes usually correspond to carrier or region-specific builds. The SM-D639B tag, in particular, is often used for Samsung's global SKU — which doesn’t guarantee availability in every country, but does hint that Samsung expects demand beyond a handful of test markets.
Does Bluetooth certification mean a launch is near?
Certification in the Bluetooth SIG doesn’t equal a launch date, but it’s a strong signal that technical validation is underway. Imagine the development checklist: prototypes, regulatory approvals and partner tweaks — Bluetooth sign-off is one of those milestones that typically precedes wider announcements.
- Multiple model numbers = broader regional support
- Bluetooth certification = hardware verification step
- Global SKU ("B") suggests an international rollout is planned
That said, rumors have floated that a U.S. release might land next year. With the device shown publicly in late October but still unannounced, Samsung may be timing a coordinated reveal or a staggered regional launch. Either way, the Bluetooth entry raises expectations that the tri-fold won’t remain a niche prototype.
What to watch next
Keep an eye out for further regulatory listings (FCC, TENAA) and any carrier certifications. Those filings often fill in gaps about connectivity bands, battery specs and shipment timing. If you’re tracking foldable innovation, this tri-fold could reshape expectations about screen real estate — and Samsung seems to be positioning it for a wide audience.
