Connectivity
Connectivity options on the Haier Z100 are minimal, consistent with early feature phones. It operates on the GSM 900/1800 bands, without support for GPRS or EDGE, focusing on voice calls and SMS services. The absence of advanced connectivity options like Bluetooth, WLAN, or USB means the device sticks strictly to its core communication roles, devoid of internet browsing or media transfer functions beyond WAP 1.2.1 for basic internet access.
