Memory and Storage
The Siemens S75 comes with 20 MB of internal memory, which was somewhat limited even at the time of release. However, it includes an RS-MMC card slot, accepting up to 1 GB of expandable storage, with a 128 MB card usually provided in the box. The phonebook can store up to 1000 contacts with multiple fields and supports photo ID for calls, a handy feature back then. Additionally, it can save records of 100 dialed, 100 received, and 100 missed calls.
