Connectivity
Connectivity options on the Plum Caliber are somewhat sparse, lacking Wi-Fi and GPS capabilities that are standard on modern devices. However, it does support Bluetooth 2.1 with A2DP for wireless connections and a microUSB port for charging and data transfer. The stereo FM radio is a useful addition for media enthusiasts, requiring just wired headphones plugged into the 3.5mm audio jack to function as an antenna.
