Memory and Storage
Internally, the Samsung X900 came with 128MB of storage, which was quite generous for that time when phones typically had limited onboard memory. However, the lack of a card slot for expandable storage meant users had to manage this space sensibly, accommodating their contacts, call logs, and multimedia files. The phone could store a reasonable number of call records, maintaining details of 20 dialed, 20 received, and 20 missed calls, which was sufficient for keeping track of recent communication.
