Unlocked 5G Smartphone

The Samsung Galaxy S21 SM-G991UZAEXAA is an unlocked 5G smartphone with a 6.2 inch Dynamic AMOLED 2X display running at 120Hz. It ships new in Phantom Gray with 8GB of RAM and a triple rear camera system rated at 64 MP, 12 MP and 12 MP. The handset supports a wide range of CDMA, GSM and LTE bands for broad carrier compatibility.

Best for single-SIM users wanting 8K video

Buyers who need a Nano SIM slot, 8K video capture at 2400 x 1080 resolution, and a 10 MP front-facing camera will find this model fits. Hybrid Optic Zoom at 3x and digital zoom up to 30x suit photography enthusiasts. Users requiring dual SIM support, expandable storage or a headphone jack should consider other devices.

Simple setup with SIM insertion

Activation requires inserting a Nano SIM and following the on-screen carrier setup. The in-display fingerprint sensor and face recognition configure quickly for biometric unlock. Common issues include forgetting to enable 5G in network settings after activation and overlooking the Zoom Lock toggle for stable telephoto shots.
