Samsung Galaxy S4 I537 Active Grey 4G LTE, Factory Refurbished
Grey (Urban Grey) units of the Samsung Galaxy S4 I537 Active, Factory Refurbished per the SKU code and the old heading, which described the lot as AT&T GSM unlocked factory refurbished stock. Grey is the low-key color for industrial Wi-Fi use and props. It is the IP67 version of the 2013 Galaxy S4 with a Full HD LCD and physical keys; LTE without VoLTE means no US service today.
The Galaxy S4 Active SGH-I537 is AT&T's 2013 water- and dust-resistant version of the Galaxy S4. It swaps the S4's AMOLED for a 5-inch Full HD TFT LCD under Gorilla Glass 2, adds physical navigation keys and a sealed body rated IP67 for one meter of water for 30 minutes, and keeps a 1.9 GHz quad-core Snapdragon 600, 2 GB of RAM, 16 GB of storage with microSD to 64 GB, an 8 MP camera with an Aqua Mode for underwater shots, a 2 MP front camera, and a removable 2,600 mAh battery. It shipped on Android 4.2 Jelly Bean and reached Android 5.0.
TG Wireless offers graded S4 Active lots to collectors, outdoor and industrial Wi-Fi users, prop houses, and exporters; its LTE has no VoLTE, so it gets no US service today.

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 S4 Active I537 is a GSM phone with 2G, 3G HSPA+, and 4G LTE data, but no VoLTE. All three US national carriers retired 3G in 2022 and T-Mobile closed 2G GSM on August 3, 2026, so this phone gets no US cellular service today. The old heading describes the units as AT&T GSM unlocked; lock state is per listing, so see the network status line in the table. Realistic uses are export to live UMTS markets, rugged Wi-Fi-only use, collectors, props, and parts.
Resale fit
- Exporters supplying markets where 3G UMTS or 2G GSM service remains live.
- Outdoor, marine, and industrial Wi-Fi-only use where an IP67 phone with physical keys is handy.
- Collectors and prop houses that want the S4 Active in Orange Flare or Urban Grey.
- Parts stock for displays, batteries, and sealed housings.
