GAMAKOO G25 Ultra 5G smartphone

The GAMAKOO G25 Ultra is an unlocked 5G smartphone with a 7 inch display running Android 15. It ships with 8GB of RAM and 256GB of internal storage. A deca-core Snapdragon 8 Gen 2 processor drives the device. Dual Nano SIM slots support two active lines.

Large-screen users and media consumers

The 7 inch HD Full Display suits people who want a big canvas for video, browsing or light gaming. The 6000mAh battery targets all-day runtime on a single charge. Buyers who prefer a compact handset, wireless charging, or a dedicated headphone jack should look elsewhere. Expandable storage requires a separate microSD card up to 128GB.

256GB internal storage

The phone provides 256GB of built-in storage for apps, photos and system files. A microSD slot accepts cards up to 128GB for additional space. If 256GB is insufficient and you do not want to manage a memory card, this model will not meet the requirement.

Questions about this item

How warm does the Snapdragon 8 Gen 2 get and how much power does it draw when the 7 inch screen runs all day?

The 6000mAh battery is designed to last through extended use with the large display, and the 5V2A charger replenishes it via USB Type-C.

Which nano SIM cards and micro SD card do I need to have ready before the phone works?

Two nano SIM cards are required for dual standby, and a micro SD card up to 128GB can be added for extra storage.

Will my existing USB Type-C headphones and 5V chargers work with this handset?

Yes, the USB Type-C port handles both audio and 5V2A charging, so current Type-C accessories are compatible.
