Video sharing requirements
Video sharing requires a 3G connection for both parties. For more information on the service, 3G network availability, and fees associated with using this service, contact your service provider.
To use video sharing, make sure:
You have the correct person-to-person settings defined, and you have accepted a video sharing invitation, or are in an active call
You have an active 3G connection and remain within 3G network coverage. If you move outside the 3G network during a video sharing session, the sharing stops, but your voice call continues.
Both the sender and recipient are registered to the 3G network. If you invite someone to a sharing session and the recipient’s device is not within 3G network coverage, does not have video sharing installed, or person-to-person connections set up, the recipient does not receive invitations. You receive an error message that indicates that the recipient cannot accept the invitation.
