Samsung Galaxy S II I777 4G 16 GB, Factory Refurbished, AT&T branded, GSM unlocked
Factory refurbished Samsung Galaxy S II I777 4G, 16 GB, AT&T branded and GSM unlocked. This is the member repair shops and parts dealers pick for working I777 boards and Super AMOLED Plus panels, and the one exporters use when the destination market wants a tested rather than sealed unit. Color is not stated.
AT&T's Galaxy S II, the SGH-I777 of 2011, is the thin 8.89 mm version of Samsung's second Android flagship: a 4.3-inch Super AMOLED Plus display, a 1.2 GHz dual-core processor, 16 GB of storage with microSD, an 8 MP camera with 1080p video, DLNA streaming, and HSPA+ data on AT&T's network. It shipped with Android 2.3 and reached 4.1. Today it is a legacy GSM handset, and TG Wireless sells it in new and factory refurbished condition to exporters serving UMTS markets, to collectors of the Galaxy S II family, and to repair shops and prop buyers who want complete, working examples.

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. Color is not stated in the listing; confirm the lot sheet with your account manager.
Network and compatibility
The Galaxy S II I777 is AT&T's HSPA+ version, marketed as 4G, with no LTE radio and no VoLTE. US 3G networks closed in 2022 and T-Mobile's 2G GSM network followed on August 3, 2026, so it gets no service on any US carrier. Lock state is per listing; see the network status line in the table. The source describes the units as AT&T GSM unlocked, so GSM and UMTS markets abroad, Wi-Fi use, collectors, props, and parts are the realistic outlets.
Resale fit
- Export to GSM and UMTS markets where the Galaxy S II is still a recognized, serviceable model.
- Collectors who want AT&T's thin Galaxy S II in new or graded condition.
- Repair shops that need Super AMOLED Plus donor units.
- Film and TV props and Wi-Fi-only roles.
