Memory and Storage
Internally, the BenQ-Siemens A58 housed 6.5MB of memory, which was modest even by the standards of its time. This limited storage was primarily designated for contacts, allowing up to 500 phonebook entries, and maintaining records of recent calls with a list of 10 dialed, received, and missed calls. The lack of a card slot meant users had to manage this space carefully, focusing on essential contacts and messages.
