Samsung Galaxy A31 A315 128 GB Prism Crush Black, New, GSM unlocked
Offered here is the Samsung Galaxy A31 A315 in Prism Crush Black with 128 GB of storage, brand new and GSM unlocked. The 128 GB tier is the one to put in front of marketplace buyers and export customers who want the larger storage without a microSD card. The listing states the Data field as 4G LTE and Wi-Fi and the Status as GSM unlocked.
The Galaxy A31 is Samsung's 2020 mid-range A-series phone, model SM-A315. It pairs a 6.4-inch FHD+ Super AMOLED panel with a MediaTek Helio P65 octa-core chip, 4 GB of RAM, a quad rear camera led by a 48 MP sensor, a 5,000 mAh battery with 15W charging, an in-display fingerprint reader, and a dedicated microSD slot. Samsung shipped it on Android 10 and carried it through two major OS updates.
Dealers take the A31 from TG Wireless as an affordable unlocked Samsung with a large AMOLED screen and a long-running battery, the two features that sell at a prepaid counter. The A315 is an international dual-SIM variant, so exporters and marketplace sellers are its steadiest buyers.

Condition: New
Brand new units in the original box with the original in-box accessories as listed. Nothing has been activated or reconditioned. If your channel needs sealed retail packaging rather than open-box new, say so when you request a quote so the account manager can confirm how the lot is packed.
Network and compatibility
The Galaxy A31 is a 4G LTE phone with VoLTE, so the US 2G and 3G shutdowns do not affect its data or calling. Lock state is per listing; see the network status line in the table. The A315 carries LTE bands 1/2/3/5/7/8/20/28/38/40/41, which cover Europe, Latin America, and Asia well, but it lacks several North American bands and is not carrier-certified in the US, so AT&T and T-Mobile acceptance and VoLTE provisioning must be confirmed with the carrier before volume activations. It takes two nano-SIMs.
Resale fit
- Export lots for Latin America, Europe, and Asia, where the A315 band set and dual-SIM slots match local networks.
- Marketplace and storefront resale of an unlocked Samsung with a 6.4-inch AMOLED screen under the Galaxy S price tier.
- Prepaid and MVNO dealers who confirm GSM band coverage with their carrier and want a 5,000 mAh Samsung for budget plans.
- Repair shops and refurbishers sourcing graded A31 units for parts matching and resale.
