You run out of space because you cannot use an SD card. Solution:

In the mid-2010s, the smartphone industry bifurcated into two philosophical camps: the "minimalist" (removing features like the headphone jack and expandable storage) and the "maximalist" (integrating every possible utility). The Honor 8X belonged firmly to the latter. While reviewers focused on its 6.5-inch FHD+ display and the Kirin 710 processor, the engineering triumph lay in its hybrid Dual SIM tray.

Despite its strengths, the Honor 8X Dual SIM system had flaws:

The Honor 8X has a sleek and stylish design that is sure to turn heads. The phone features a 6.59-inch Full HD+ display with a resolution of 1080 x 2340 pixels, providing a crisp and clear visual experience. The screen has a 19.5:9 aspect ratio, making it perfect for watching videos, browsing the web, and playing games. The phone's body is made of durable materials, with a metallic finish that gives it a premium feel.

In Western Europe, professionals used the 8X to carry a corporate SIM (roaming locked) and a personal prepaid SIM. Unlike flagship iPhones (which only introduced Dual SIM with the XS Max at triple the price), the Honor 8X allowed users to physically disable one SIM via software without removing the tray, effectively "clocking out" of work.
