Samsung A777 Green 3G AT&T, A Grade, GSM unlocked
This Samsung A777 Green 3G is a GSM unlocked A Grade (A-Stock) unit from the AT&T variant: lightly used, fully tested, and working, with very minor marks at most. The units originally came back through a carrier channel and were tested and graded by TG. It serves the same buyers as the other green slider: exporters to live GSM markets, prop houses, and parts suppliers who want a clean example.
The Samsung A777 is a 2008 AT&T 3G slider, the successor to the A737, with a 1.3-megapixel camera that also captures video, GPS for AT&T Navigator, Bluetooth with stereo streaming, a multi-format music player, a microSD slot rated to 8 GB, quad-band GSM for roaming, and up to 3 hours of talk time. Its 3G radio runs UMTS/HSDPA on 850/1900 MHz with EDGE fallback, which made it one of AT&T's mainstream multimedia feature phones of its year.
TG Wireless sells the A777 to exporters serving markets where 2G GSM or 3G UMTS is still live and sliders sell at the counter, to prop and collector buyers who want a colorful late-2000s AT&T handset, and to parts suppliers. It cannot be activated on a US carrier.

Network and compatibility
The A777 is a 3G UMTS/HSDPA phone with 2G GSM/EDGE fallback and no LTE or VoLTE. Lock state is per listing; see the network status line in the table. AT&T retired 3G in February 2022 and its 2G network in January 2017, and T-Mobile ended 2G GSM on August 3, 2026, so the A777 gets no US service today regardless of the AT&T branding or the AT&T / H20 category. GSM unlocked units still work abroad where 2G GSM or 3G on 850/1900 MHz remains live, and the phone works offline as a music player and camera.
Resale fit
- Export to markets in Latin America, Africa, and Asia where 2G GSM or 850/1900 MHz 3G is still live and slider phones sell.
- Prop houses and collectors who want a late-2000s AT&T slider in one of four bright colors.
- Parts and refurbishing stock for shops supporting the SGH-A777 line.
- Offline use as a basic music player and camera where no cellular service is needed.
