Samsung Infuse 4G I997 16 GB, Factory Refurbished, AT&T GSM unlocked
Here the Samsung Infuse 4G I997 comes Factory Refurbished and GSM unlocked: 4.5-inch Super AMOLED Plus, 1.2 GHz, 8 MP camera, 16 GB storage, and HSPA+ data on AT&T bands. Unlocked refurbished Infuse units suit exporters who need a working big-screen Android for UMTS markets and repair shops that want tested donors.
The Samsung Infuse 4G, model SGH-I997, was AT&T's thinnest and largest Android phone when it launched in May 2011: a 4.5-inch Super AMOLED Plus screen, a 1.2 GHz processor, Android 2.2 Froyo, an 8 MP camera with 720p HD video, a front camera, 16 GB of internal storage with a microSD slot, HDMI output over microUSB, and AT&T's HSPA+ data, which AT&T marketed as 4G.
Dealers buy the I997 from TG Wireless for export to markets with live GSM and UMTS service, for collector and prop use as a landmark early big-screen Samsung, and as a Wi-Fi media device or parts donor.

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
Despite the 4G name, the Infuse uses HSPA+ on 3G UMTS bands and has no LTE. US carriers retired 3G in 2022 and T-Mobile closed 2G GSM on August 3, 2026, so the I997 gets no US service. Lock state varies by listing; see the network status line in the table and confirm with your account manager where it is not stated. Abroad, it works on live GSM and UMTS networks, and Wi-Fi, media, and HDMI output work anywhere.
Resale fit
- Export lots for markets where UMTS/HSPA service continues.
- Collector and prop buyers wanting the first 4.5-inch Super AMOLED Plus Samsung.
- Repair benches sourcing Infuse screens, batteries, and housings.
- Wi-Fi media and display units.
