Samsung Galaxy S4 Active SGH-I537 16 GB Gray 4G LTE, A Grade, GSM unlocked
Gray Samsung Galaxy S4 Active I537 handsets, 16 GB, 4G LTE, sold as Carrier Returns A-stock: returned through a carrier channel, tested by TG, and graded A for light wear at most, GSM unlocked per the old listing. Urban Gray is the neutral finish that prepaid counters and export buyers prefer when the phone has to sell on price and the rugged build rather than on color.
The SGH-I537 is the AT&T version of the 2013 Galaxy S4 Active, Samsung's first water- and dust-sealed flagship: IP67 rated, with a 5-inch full HD LCD behind Gorilla Glass 2, physical front buttons, a 1.9 GHz quad-core Snapdragon 600, 2 GB of RAM, 16 GB of storage plus microSD, an 8 MP camera, and a removable 2,600 mAh battery. It carries AT&T's LTE bands and Android 4.2 as shipped. TG Wireless sells the I537 to buyers who want a rugged-style LTE Android at a legacy price: fleet and field-service accounts, prepaid dealers on GSM networks, exporters, and repair shops that need complete units.

Condition: A Grade
A Grade (A-Stock) units are lightly used, fully tested, and working, and may show very minor nicks or scratches. Units are supplied as graded; ask your account manager about packaging (original box, accessories, or handset only) when you request a quote.
Network and compatibility
The I537 is a 4G LTE phone on AT&T's GSM bands, so it survived the 2022 3G retirement and the 2026 2G closure on paper; in practice an activation depends on whether the carrier still whitelists this 2013 model for VoLTE, which must be confirmed with the carrier. Lock state is per listing; see the network status line in the table. Unlocked units also serve GSM export markets whose LTE bands overlap AT&T's.
Resale fit
- Fleet, warehouse, and field-service buyers who want a sealed Android at a low unit cost.
- Prepaid and MVNO dealers on GSM networks that still accept the model.
- Exporters supplying LTE Samsung handsets to GSM markets.
- Repair shops stocking complete donor units.
