Memory and Storage
Internally, the J630 was modest, coming with 40MB of storage. This space was practical for storing contacts, messages, and a few photos. However, its storage limitations could be mitigated with a microSD card, thanks to its dedicated slot, allowing users to expand memory capacity for additional song files or images. The phonebook had a reasonable capacity, supporting up to 1000 entries, and diligently tracked up to 20 records each of dialed, received, and missed calls.
