Performance and Storage
Internally, the Samsung B510 offers only 4MB of memory, which was sufficient for storing essential contacts and messages. The phone does not support expandable memory through a card slot, a notable limitation by today's standards, but not uncommon at the time for entry-level devices. It can store up to 500 contacts and also supports photocall functionality, allowing users to attach photos to contact entries stored in the phonebook. For call management, it retains records of the last 30 dialed, received, and missed calls.
