Memory and Storage
One of the J210’s limitations by modern standards is its storage capacity. The phone comes with 600 KB of internal memory, which may seem minuscule today but was average for devices of its category at the time. This space accommodates up to 50 short messages, ensuring users could keep a concise message history. However, the absence of a card slot for expandable memory means users are confined to the built-in storage for all their contacts and messages. The phonebook is capable of storing up to 200 entries, and the feature of picture call, while basic, added a personalized touch to contacts.
