📱 What is a Feature Phone?

A feature phone is a mobile phone that sits between a basic phone and a smartphone.

• It offers core functions like calling, SMS, and sometimes limited internet access.
• Unlike smartphones, feature phones usually have physical keypads (T9 or QWERTY), smaller screens, and simpler operating systems.
• They may include some “smart” features (camera, music player, basic apps), but not the full app ecosystem of Android or iOS.

🔑 Key Characteristics

• Physical keypad: Numeric or QWERTY.
• Small display: Non-touch or limited touch.
• Lightweight OS: Proprietary systems, or modern lightweight OS like KaiOS.
• Connectivity: 2G/3G/4G, sometimes Wi-Fi and Bluetooth.
• Battery life: Much longer than smartphones (days instead of hours).
• Durability: Often more rugged and affordable.
