Performance and Memory
Internally, the OT-V670 offers 10MB of storage, which was suitable for the phone's expected usage, considering its main functions and limited application support. The device allows for microSD expansion via a dedicated slot, an appreciated feature for those needing additional space for contacts or multimedia. The phonebook supports up to 800 entries and includes photo call functionality, a useful feature that was ahead of basic caller ID systems. The call records are equally well-organized, recording 20 dialed, 20 received, and 20 missed calls.
