Audio and Connectivity
Beyond essential sound functions like a loudspeaker and polyphonic ringtones, the Samsung M130's audio capabilities are rudimentary, lacking a 3.5mm headphone jack. This reflects its primary purpose as a communication device rather than a music player. Connectivity is extremely limited by today's standards; it doesn't offer technologies such as WLAN, Bluetooth, or GPS, and uses a proprietary USB connection, making data transfer somewhat challenging and reducing compatibility with contemporary accessories.
