Unlocked Android 13 Smartphone with 256GB Storage

The Samsung Galaxy S23 Ultra arrives new and unlocked, running Android 13 on 8GB of RAM with 256GB of internal storage. Its 6.8-inch display provides a large canvas for media, productivity and the integrated S Pen. This configuration suits users who want flagship camera capabilities and pen input without carrier restrictions.

5000mAh Battery with Super-Fast Charging

A 5000mAh battery powers the device through extended shooting sessions and heavy multitasking. Super-Fast Charging replenishes the cell quickly when needed. The adaptive 120Hz refresh rate scales dynamically to conserve energy during static content while maintaining smooth motion for gaming and scrolling.

Upgrade from Smaller S23 Models for Night

Compared with the 6.1-inch S23 and 6.6-inch S23+, this Ultra model adds a 200MP main camera, Nightography low-light processing and a built-in S Pen for precise annotation and remote shutter control. The jump is worthwhile for creators who need maximum sensor resolution, superior night video stabilisation and pen-driven workflows in a single handset.

Questions about this item

How do I insert the nano-SIM into the Galaxy S23 Ultra, and which way up does the tray go?

Power off the phone, push the ejector pin into the small hole on the bottom edge, pull out the tray, place the nano-SIM with the gold contacts facing down and the notched corner aligned, then slide the tray back in until it clicks flush.

What part will need replacement first on the Galaxy S23 Ultra, and how can I tell?

The 5,000mAh battery will gradually lose capacity; when a full charge no longer lasts a typical day or the device shuts down unexpectedly, the battery should be replaced by an authorised service centre.

What limit appears first during long 200MP recording sessions on the Galaxy S23 Ultra?

The phone will throttle performance and may stop recording once internal temperature reaches its safety threshold, protecting the processor and battery from overheating.
