Connectivity
Connectivity options on the K500 are reflective of its time. It operates on the GSM 900/1800/1900 frequency bands but lacks EDGE capability, relying instead on GPRS Class 10 for data services. The absence of Bluetooth, WLAN, and radio facilities indicates a focus on basic calling and messaging. An infrared port is included, providing a means for short-range data transmission with compatible devices. The phone also features a proprietary USB interface for data and charging purposes.
