Samsung Galaxy A51 (SM-A515), Quoted per lot, lock state quoted per lot
This page covers the Samsung Galaxy A51, the 4G LTE model SM-A515, as a model-level listing: storage, color, grade, and lock state are quoted per lot by your account manager. Dealers use it to request a mixed or single-configuration quantity of the A51 for prepaid, MVNO, and trade-in programs when the fixed color and storage pages do not match the quantity they need.
The Galaxy A51 is Samsung's best-selling mid-range phone of 2020: a 6.5-inch FHD+ Super AMOLED Infinity-O display, the Exynos 9611 octa-core chip, 64 or 128 GB of storage with a microSD slot up to 512 GB, a quad camera led by a 48 MP main sensor, a 32 MP front camera, a 4,000 mAh battery with 15 W charging, an in-display fingerprint reader, a headphone jack, and the Prism Crush finishes. It shipped on Android 10 and received updates through Android 13.
Dealers buy the A51 from TG Wireless as the volume Samsung for prepaid and MVNO activations, trade-in replacement pools, and marketplace resale, where a large AMOLED screen and a recognizable Samsung name sell at a mid-range ticket.

Condition: Quoted per lot
TG Wireless offers this model in the grades available at the time of your inquiry, which can include new, A+ Grade, A Grade, and B Grade. Every quote states the grade, the storage, and the color mix. Ask the account manager for packaging status (original box, accessories, or handset only) and for the activation-lock and carrier-status checks TG performs on used units before they ship.
Network and compatibility
The Galaxy A51 is a 4G LTE phone with VoLTE, so it is unaffected by the US 2G and 3G retirements. Lock state is per listing; see the network status line in the table. GSM unlocked units register on AT&T, T-Mobile, and their prepaid brands; Verizon and other carriers accept the model only in specific variants, and the regional model number (US SM-A515U or international SM-A515F) sets the band list, so confirm the variant and VoLTE provisioning with the carrier before volume orders. It takes a nano-SIM.
Resale fit
- Prepaid and MVNO activations where a 6.5-inch Samsung AMOLED phone at a mid-range ticket is the volume Android.
- Trade-in replacement and insurance pools that want one model in consistent grades across four colors and two storage tiers.
- Marketplace and storefront resale of new and graded units sold by color.
- Export to Latin America and other GSM markets where the A51 was a top seller and remains in demand.
