Memory and SIM
When it comes to memory, the N331i offers storage for up to 500 phonebook entries with a photo call feature. Call records are stored efficiently, maintaining logs for 10 dialed, received, and missed calls each. The absence of a card slot highlights the era's limitations in expandable storage options, meaning users had to manage phone memory judiciously. The phone uses a Mini-SIM, which was the norm at the time.
