Performance and Memory
Performance-wise, the Sharp 904 operates with network technologies, including GSM and UMTS, allowing 2G and 3G connectivity, capped at a speed of 384 kbps. With an internal memory of 20MB, it may seem quite limited by today’s standards. However, for the time, it accommodated basic applications and contact storage efficiently, with the option to expand via a miniSD card slot. The phonebook features support photo calls, and it can keep a log of 10 dialed, received, and missed calls, giving users essential call management tools.
