Storage and Connectivity
The Ericsson GF 788e was a device built for the essentials; hence, it featured a phonebook capable of storing up to 99 entries. There was no support for expandable memory via card slots, WLAN, GPRS, EDGE, or even USB connectivity, which aligns with the focus of mobile phones of that era on voice communication rather than data services. The absence of a 3.5mm audio jack or Bluetooth further emphasizes its strictly utilitarian design.
