Connectivity and Sound
Connectivity options were limited to GSM 2G networks, and the JAMA 101 supported GPRS for mobile internet without EDGE capabilities. Bluetooth 1.2 was available for wireless peripherals, while USB connectivity was facilitated through a miniUSB 1.1 port. As for audio, the device included a loudspeaker for hands-free use and supported vibration and downloadable polyphonic or MP3 ringtones, but it lacked a standard 3.5mm headphone jack.
