Samsung Galaxy S25 Ultra 256GB Titanium Black cell phones - unlocked

What the S25 Ultra delivers

The Samsung Galaxy S25 Ultra is an unlocked Android smartphone with a 6.9 inch Dynamic AMOLED2X display running at up to 120 Hz and a peak brightness of 2600 nits. It ships with 256 GB of UFS 4.0 storage and 12 GB of RAM driven by the Snapdragon 8 Elite for Galaxy chip. The quad-camera array pairs a 200 MP main sensor with 50 MP ultrawide, 50 MP periscope and 10 MP telephoto modules. IP68 sealing and Gorilla Armor 2 glass protect the titanium frame.

Sustained performance under load

The 3 nm Snapdragon 8 Elite for Galaxy processor maintains high clock speeds during extended gaming or on-device AI workloads thanks to a vapour-chamber cooling system that spreads heat across the chassis. The 5000 mAh battery supports 45 W wired charging, Qi2 wireless charging and reverse wireless charging, keeping the phone running through a full day of heavy use. Adaptive 120 Hz refresh drops to lower rates when static content is shown, conserving power without user intervention.

Who should consider a different device

Buyers who need expandable storage via microSD will not find a slot on this model. Shoppers requiring dual physical SIM cards are limited to a single nano SIM plus eSIM support. Users who prefer a more compact handset may find the 6.9 inch footprint too large for one-handed operation. Anyone tied to a carrier that does not support the listed 5G n1 band should verify compatibility before purchase.
