Performance and Storage
This phone was designed with practical data storage capabilities for the time, featuring a phonebook capacity of 250 entries and support for 5 contact groups. However, it lacked a memory card slot, limiting the user's ability to expand storage beyond what was internally provided. The call records feature enabled the storage of 20 received, dialed, and missed calls, ensuring users could easily track recent communications.
