Samsung A157 3G, Factory Refurbished, GSM unlocked
Samsung A157 3G is a factory refurbished SGH-A157 clamshell, GSM unlocked, on quad-band GSM and UMTS 850/1900 with no LTE. Refurbished units at this price suit exporters who sell voice-and-text flips in markets with live 3G, and small-business buyers who want a working offline or spare device; the unlocked state saves an unlock step before shipping abroad.
The Samsung SGH-A157 was AT&T's GoPhone prepaid flip of 2012: a compact clamshell for people who wanted calls and texts with a basic browser, speakerphone, and 256 MB of storage, running on quad-band GSM and AT&T's UMTS/HSDPA 3G network on 850 and 1900 MHz. It has an 800 mAh battery rated for five hours of talk, a micro-USB port, and no camera. It never had LTE, which is the fact that defines its market today.
TG Wireless offers the A157 new and factory refurbished to exporters building lots of simple 3G flips for markets where UMTS and GSM remain live, and to prop and collector buyers.

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 Samsung A157 is a 3G UMTS and quad-band GSM phone with no LTE, so it has no service path on US carriers today: the national 3G networks were retired in 2022 and T-Mobile's 2G GSM on August 3, 2026; see the network status line in the table. Its UMTS 850/1900 and quad-band GSM still give it voice and text in export markets where those networks remain live, and AT&T-locked units need an unlock first. Domestic uses are collector, prop, offline, and parts.
Resale fit
- Export to markets with live GSM or UMTS where a compact, low-cost flip for voice and text sells to prepaid customers.
- Prop houses and collectors who want a recent-era AT&T GoPhone flip.
- Parts and refurbishment stock for the A157 line.
