Description
Samsung Galaxy Exhilarate I577 4G LTE, Factory Refurbished, GSM unlocked
Reconditioned to close-to-new working order and tested and graded by TG, this factory refurbished Samsung Galaxy Exhilarate I577 is the AT&T 4G LTE eco phone, GSM unlocked, with a 4.0-inch Super AMOLED screen and Android 2.3. It no longer activates on US carriers; collectors, prop houses, and GSM export buyers are the realistic customers for this unit.
The Galaxy Exhilarate, model SGH-I577, was AT&T's 2012 eco-labeled LTE phone, built with recycled plastics and the first Samsung and AT&T handset to earn UL Platinum Environmentally Preferable status. It has a 4.0-inch Super AMOLED display at 480 x 800, a 1.2 GHz dual-core processor, 1 GB of RAM, 4 GB of storage with a microSD slot, a 5 MP rear camera with LED flash, a 1.3 MP front camera, and a 1,750 mAh battery. It shipped on Android 2.3 Gingerbread with AT&T 4G LTE, Wi-Fi, Bluetooth 3.0, and GPS.
TG Wireless offers the Exhilarate in A Grade for collectors, prop houses, and exporters to GSM markets; it has no US network service.

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
The Exhilarate has LTE for data, but voice ran over 2G/3G GSM. It never received VoLTE, so it does not activate on US carriers despite the LTE radio. A phone without LTE and VoLTE gets no service on US carriers today: the three national carriers retired 3G in 2022 and T-Mobile closed its 2G GSM network on August 3, 2026. Realistic uses are export to GSM and UMTS markets, Wi-Fi use, collectors, props, and parts. Lock state is per listing; see the network status line in the table.
Resale fit
- Collectors of early LTE and eco-design phones.
- Film and TV prop departments dressing 2012 AT&T scenes.
- Export to GSM markets where 3G voice still runs and the AT&T LTE bands overlap.
