Samsung Metro 313 (SM B313E) (Blue)

Durable, budget-friendly, and user-friendly feature phones designed for straightforward, reliable communication. These phones typically feature a 2.0 to 2.4-inch TFT or QVGA display, traditional alphanumeric keypads, and a compact, lightweight bar-form factor that fits comfortably in the pocket. Designed for efficiency, they usually include Dual SIM (GSM+GSM) functionality, 16MB-64MB of RAM, and up to 16GB of expandable storage via a microSD card slot for music and images. The devices are equipped with 0.3 MP to 3.1 MP rear cameras, and often include a built-in flash/torch, FM radio, and Bluetooth v2.1 for data sharing. A major selling point is the long-lasting 1000 mAh to 1200 mAh removable battery, offering up to 12-13 hours of talk time and multi-day standby, making them ideal for seniors or as secondary "rough and tough" work phones.
