Memory and Phonebook
Storage capabilities of the Siemens SL10 were reflective of its time. Without a memory card slot, the storage was limited but functional, with the ability to store 50 phonebook entries. Call records were also minimal, maintaining logs of only 10 dialed, 10 received, and 10 missed calls. While this appears meager by modern standards, it was adequate for the phone's primary function of communication.
