Description
Samsung Galaxy A5 A520 Black Sky, A Grade, GSM unlocked
Listed as A-stock, this Samsung Galaxy A5 A520 in Black Sky is a 4G LTE GSM unlocked unit sourced through a carrier-return channel and tested and graded A Grade by TG Wireless: lightly used, fully working, with at most very minor marks. Prepaid stores and marketplace sellers take A Grade A520s as a low-ticket Samsung with a glass back that still presents well on a shelf.
The Galaxy A5 (2017), model SM-A520, is Samsung's upper mid-range phone from early 2017: a 5.2-inch Full HD Super AMOLED panel, an octa-core Exynos 7880, 3 GB of RAM, 32 GB of storage with a microSD slot, and 16 MP cameras front and rear. It was the first A series phone with IP68 water and dust resistance, a USB-C port, Always On Display, and Samsung Pay, and the glass-and-metal body has no camera bump. It shipped on Android 6.0.1 and later received Android 8.0.
Dealers buy the A5 A520 from TG Wireless as a compact, well-built LTE Samsung for prepaid activations, export lots where the model is still recognized, and repair-shop parts and swap stock.

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 Galaxy A5 A520 is a 4G LTE phone, so the US 3G shutdowns in 2022 and T-Mobile's 2G retirement on August 3, 2026 do not take it off the air by themselves, but calls now need VoLTE and carrier acceptance depends on the exact regional variant. The SKU on these lots points to the A520W variant, so confirm LTE bands and VoLTE whitelisting with the carrier before buying for US activations. Lock state is per listing; see the network status line in the table. It takes a nano-SIM.
Resale fit
- Prepaid and MVNO counters on GSM carriers that still accept the A520 variant, after a VoLTE check.
- Export to Latin America, Europe, and Asia, where the A5 (2017) sold widely and LTE band coverage is broad.
- Repair shops that need tested donors for screens, frames, and boards on the A520 platform.
- Marketplace resale of graded units in the four original nature-named colors.
