Memory and Storage
The Sony Ericsson Z600 offers limited internal storage of 1.5MB, which was relatively common during the early 2000s, sufficient for a few photos, a modest number of contacts, and text messages. Lacking a memory card slot, the storage could not be expanded, which necessitated efficient space management. The phonebook could hold up to 500 entries, complete with eight fields each and support for photo call, giving users a practical way to personalize contacts despite the storage limitations.
