Memory and Storage
Memory capabilities in the Siemens S10 were minimal, as expected for a phone of its time. It lacked a card slot, which reflects its primary design as a communication device rather than a multimedia gadget. The phone's internal memory structure could store up to 50 contacts in its phonebook and maintain a call log of 10 dialed, 10 received, and 10 missed calls. These features catered to the fundamental communication needs of users during that period.
