Condition: C Grade
C Grade units are fully tested and working but carry heavy cosmetic wear, such as deep scratches, dents, or screen marks. They suit repair, refurbishment, and value channels where the device is re-housed or sold as clearly used.
Network and compatibility
Every S20 Ultra is a 5G phone with full 4G LTE and VoLTE; the listings that say 4G LTE describe the LTE service, not a separate LTE-only model. The US 2G and 3G retirements do not affect it. Lock state is per listing; see the network status line in the table. GSM/CDMA unlocked US units cover AT&T, T-Mobile, and Verizon bands; GSM unlocked lots may be international G988B units whose US band and VoLTE support vary, so confirm the variant and carrier acceptance before buying for activations.
Resale fit
- Premium prepaid and MVNO activations where a 6.9-inch 5G flagship with 10x zoom is the top of the shelf.
- Marketplace and storefront resale of graded 128 GB units in Cosmic Gray and Cosmic Black.
- Refurbishment operators and repair shops buying C Grade and carrier-return lots for reconditioning or parts.
- Export to LTE and 5G markets where the Snapdragon or Exynos variant matches local networks.
