Mobile phones now have functionality and applications that provide a wide variety of communication modes. For example, a single device can now support conventional phone calls, Voice-over-Internet-Protocol (VoIP) calls, video calls, and the like. However, such functionality has not been particularly well integrated, and new users may not even be aware that such functionality is available to them.
Because users can face hurdles when attempting to take advantage of different communication modes, there remains room for improvement.
