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
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.
