Unlocked 5G Smartphone with 128 GB Storage

The Samsung Galaxy S21 5G is an unlocked smartphone with 128 GB of internal storage and 8 GB of RAM. It runs Android 11 on a Snapdragon 888 octa-core processor. The device suits users who want a carrier-free handset with a triple rear camera system and a high-refresh-rate display.

Dynamic AMOLED 2X Display at 120 Hz

The 6.2 inch Full Rectangle screen (6.1 inch rounded corners) uses Dynamic AMOLED 2X technology with a 2400 x 1080 FHD+ resolution and a 120 Hz refresh rate. The panel shows 16 million colours. Wireless connectivity relies on Wi-Fi 802.11 a/b/g/n/ac/ax with HE80, MIMO and 1024-QAM on 2.4 GHz and 5 GHz bands. The single Nano SIM slot limits the phone to one active line at a time.

Straightforward Setup with Single SIM Constraint

Insert a Nano SIM and power on to begin the Android setup wizard; the unlocked firmware works with most compatible networks without extra steps. The in-display fingerprint sensor and face recognition simplify unlocking. The fixed 128 GB storage cannot be expanded, so buyers who need more space for 8K video or large apps should consider this limit before purchase.
