Samsung Exhilarate I577 Black QX, New, GSM Unlocked
Black and GSM unlocked, this new Samsung Exhilarate I577 is the 2012 AT&T LTE-era Android smartphone, listed here as the QX stock line. The source gives the name, color, and lock state only, so buyers should treat it as a brand-new unlocked I577 and confirm packaging per lot. It suits exporters and collectors of AT&T-era Samsung Android handsets.
The Samsung Exhilarate, model SGH-I577, is the 2012 AT&T Android smartphone that AT&T positioned as an eco-conscious 4G LTE handset with a casing made partly from recycled material. It is an LTE-era Android touchscreen from before VoLTE, so its LTE radio handled data only and voice ran over the now-retired 3G network. The listing for this black unit gives the name, color, and GSM unlocked state only, so detailed specifications are not repeated here.
TG Wireless offers new, GSM unlocked Exhilarate I577 units to exporters serving live GSM and UMTS markets, to collectors of AT&T-era Samsung Android phones, and to Wi-Fi, trainer, and parts buyers.

Condition: New

Network and compatibility
The Samsung Exhilarate I577 is a GSM / HSPA / LTE phone from before VoLTE, so its LTE radio carried data only and voice calls depended on 3G. US carriers retired 3G in 2022 and T-Mobile closed 2G GSM on August 3, 2026, which leaves it without US voice service today even where its LTE bands match. Lock state is per listing; see the network status line in the table. Abroad it registers on live GSM and UMTS networks.
