Video calls
To be able to make a video call, you need to be in the coverage
of a UMTS network. For availability of and subscription to
video call services, contact your network operator or service
provider. While talking, you can see a real-time, two-way
video between you and the recipient of the call, if the
recipient has a compatible mobile phone. The video image
captured by the camera in your device is shown to the video
call recipient. A video call can only be made between two
parties.
