Samsung Katalyst SGH-T739 WI-FI, Factory Refurbished, T-Mobile branded, GSM unlocked
Factory Refurbished Samsung T739 Katalyst WI-FI, the UMA-capable slider, T-Mobile branded and GSM unlocked, reconditioned to close-to-new working order. Collector shops that want a clean example of a 2007 Wi-Fi calling phone, and exporters who need uniform cosmetics across a 2G lot, choose this tier over carrier returns.
Samsung's Katalyst SGH-T739 is a slim 2007 T-Mobile slider built for the carrier's HotSpot @Home service: it carries 802.11b/g Wi-Fi for UMA voice calls alongside quad-band GSM with EDGE. It adds a 1.3 MP camera with video, an MP3 player, a microSD slot, Bluetooth, speaker-independent voice recognition, and instant messaging clients, and supported myFaves plans.
TG Wireless sells the Katalyst new, refurbished, and as graded carrier returns to collectors interested in early Wi-Fi calling phones, to prop departments, to exporters for 2G GSM markets, and to parts dealers. It does not get US service today.

Condition: Factory Refurbished
Factory refurbished units have been reconditioned to close-to-new working order. They are not brand new and may show light signs of handling. TG tests and grades each unit before it ships. Tell your account manager whether you need units with the original box and accessories or handset-only packs; the mix varies by lot.
Network and compatibility
The Katalyst SGH-T739 is a 2G GSM phone with GPRS or EDGE data and no 3G, LTE, or VoLTE. The source lists quad-band GSM. US carriers retired 3G in 2022 and T-Mobile switched off its 2G GSM network on August 3, 2026, so this handset no longer gets voice or data service on any US network. Lock state is per listing; see the network status line in the table. Realistic uses are export to markets with live GSM service, collectors, props, and parts. Its UMA Wi-Fi calling used T-Mobile's retired HotSpot @Home service.
Resale fit
- Collector and retro-tech shops that stock working T-Mobile feature phones from the late 2000s.
- Export lots for regions where 2G GSM service is still live and a simple tested handset sells at a low ticket.
- Film, TV, and theater prop departments that need period-correct handsets in a known color.
