Design and Build
At first glance, the NIU Niutek 3.5B presents a compact design with dimensions of 113.6 x 62 x 13.8 mm and a lightweight frame, weighing 92 grams without the battery. This compactness makes the phone quite comfortable to hold and easy to use with one hand. The phone supports dual Mini-SIM cards, which is advantageous for users needing separate service plans or traveling across networks. Available in classic black and white colors, it maintains a minimalist aesthetic, suited for those who value simplicity.
