Samsung Galaxy S II I777 4G QX 16 GB, New, AT&T branded, GSM unlocked
The Samsung Galaxy S II I777 4G QX is a second new listing of AT&T's Galaxy S II, 16 GB, GSM unlocked, with a SKU that indicates black. The QX suffix is carried as it appears in the listing. Collectors wanting a boxed black I777 and exporters filling UMTS-market orders are the buyers for this one.
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: New
Brand new units in the original box with the original in-box accessories as listed. Nothing has been activated or reconditioned. If your channel needs sealed retail packaging rather than open-box new, say so when you request a quote so the account manager can confirm how the lot is packed.
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.
