ZTE S158 TD-LTE Dual SIM

The ZTE S158 feels compact in the hand, measuring 63 mm wide, 145 mm tall and just 12.5 mm thick while weighing 220 grams. Its front is dominated by a 3.5‑inch colour TN‑TFT LCD screen that delivers a resolution of 320 by 480 pixels, offering a modest but clear view for everyday tasks such as messaging, web browsing and media playback.

Running Google Android 5.1.1 Lollipop, the device is equipped with 0.5 GiB of RAM, which provides enough memory for basic apps and multitasking on a budget‑friendly smartphone. Power comes from a 2000 mAh battery intended to keep the phone active through a typical day of use, and connectivity is handled via a single SIM slot, keeping the design simple and straightforward.
