Unlocked Android 15 smartphone with S Pen

The GAMAKOO G25 Ultra ships factory unlocked and runs Android 15 out of the box. It is aimed at buyers who want a single device that handles two Nano SIMs and still leaves room for a MicroSD card. The 6.8 inch display and included S Pen suit note-taking and media consumption on the go.

Dual SIM flexibility with expandable storage

Two Nano SIM slots let you separate work and personal lines or add a local data plan when travelling. The hybrid tray accepts a MicroSD card instead of the second SIM, so you can grow the 256GB internal storage without giving up dual-SIM capability. 5G, 4G, Wi-Fi and Bluetooth keep the phone connected in most environments.

6000mAh battery for extended daily use

A 6000mAh cell powers the Snapdragon 8 Gen2 deca-core processor and 8GB of RAM through typical mixed workloads. The large capacity reduces the need for midday top-ups while the efficient chipset keeps thermals and fanless noise in check during normal operation.

Questions about this item

How long does the 6000mAh battery last under sustained use?

The 6000mAh battery supports all-day operation, though exact screen-on time varies with brightness, 5G signal strength and background apps.

Does the Snapdragon 8 Gen2 Deca Core processor run hot or loud during continuous load?

The phone uses passive cooling; it warms under heavy tasks but has no fan, so it stays silent while throttling to manage temperature.

Must I already own a Nano SIM card to activate service on this unlocked phone?

Yes, the dual Nano SIM slots require active Nano SIM cards from your carrier; the phone ships without any SIM installed.
