Connectivity
In terms of connectivity, the Ch@t 527 offers basic options for its users. It includes WLAN capabilities via Wi-Fi 802.11 b/g/n, Bluetooth 2.1 with A2DP, but lacks modern GPS positioning features. The inclusion of a microUSB 2.0 port facilitates charging and file transfer, which was standard for devices of its time. The presence of SNS (Social Network Service) integration reflects its emphasis on staying connected socially, even without a sophisticated mobile operating system.
