Samsung Sidekick 4G SGH-T839, A Grade carrier return, T-Mobile branded
Listed as Sidekick-4g-cr Carrier Returns A-stock, this is a Samsung Sidekick 4G that came back through a carrier channel and was tested and graded A Grade by TG Wireless, with light use and at most very minor marks. It is the T-Mobile Android 2.2 slider with a 3.5-inch touchscreen and five-row keyboard, which makes it a fit for collectors and prop houses rather than activation.
The Sidekick 4G is the 2011 Android revival of the Sidekick line, built by Samsung for T-Mobile as model SGH-T839. It pairs a 3.5-inch WVGA touchscreen with a five-row slide-out QWERTY keyboard, a 1 GHz Samsung processor, Android 2.2 with Sidekick Group Text and Cloud Text, a 3 MP camera, Wi-Fi, and HSPA+ data on T-Mobile's AWS band with quad-band GSM. The listing is a carrier-return lot graded A-stock, with no color stated.
Collector shops, prop houses, and parts dealers buy the Sidekick 4G from TG Wireless as a tested, graded example of the last Sidekick, since its GSM/UMTS radios get no US service today.

Condition: A Grade
A Grade (A-Stock) units are lightly used, fully tested, and working, and may show very minor nicks or scratches. Units are supplied as graded; ask your account manager about packaging (original box, accessories, or handset only) when you request a quote. Carrier-return units are graded by TG on receipt; color, packaging, and accessories are not stated, so confirm with your account manager.
Network and compatibility
The Sidekick 4G is a GSM/HSPA+ phone whose "4G" means HSPA+ data; it has no LTE radio and no VoLTE. US 3G retired in 2022 and T-Mobile shut down 2G GSM on August 3, 2026, so it gets no US service. These are T-Mobile units and the lock state is not stated; see the network status line in the table. Realistic uses are collectors, film and TV props, Wi-Fi-only Android use, parts, and export to markets where UMTS 2100 or GSM service still runs, if unlocked.
Resale fit
- Collector and nostalgia resellers who want a graded Samsung Sidekick 4G slider.
