Memory and Storage
In terms of memory, the Siemens CF75 offers basic functionality. It does not feature a card slot, so users are limited to the 10MB of internal storage. The phonebook can hold up to 1000 contacts, each with up to 20 fields, and supports photo calling. Call records cover a modest amount of data with the ability to store details of the last 10 dialed, 10 received, and 10 missed calls. While this might be restrictive to those accustomed to the limitless possibilities of current phones, it served the needs of many users at the time adequately.
