Connectivity
Connectivity on the Sagem my400V is minimal. It operates on GSM 900/1800 networks supporting GPRS Class 10 for basic data capabilities. There's no support for EDGE, wireless LAN, Bluetooth, or USB connectivity, which limits its interaction with other devices and confines it to being a standalone mobile phone. The presence of an infrared port is a nod to older methods of device communication, primarily for transferring contacts, but lacks practicality in modern contexts.
