Polycom RealPresence Mobile is for business professionals who want to extend their enterprise video collaboration capabilities beyond the office and conference room to their mobile devices.  You must not be in violation of your wireless data service agreement, if any, when using Polycom RealPresence Mobile.  RealPresence Mobile is an easy-to-use video app that provides premium quality audio, video and content sharing.  IMPORTANT NOTE: For optimal use, Polycom recommends provisioning and management through Polycom RealPresence platform.  Cloud-based deployment gives users access to enterprise directories at the swipe-of-a finger.  Users simply highlight a name, connect, and then collaborate.  Because some mobile network operators may prohibit or restrict the use of Voice over Internet Protocol (VoIP) functionality over their networks, such as the use of VoIP telephony over a cellular network, and may also impose additional fees, or other charges in connection with VoIP, POLYCOM recommends that you check the terms of your agreement with the operator prior to any use of the RealPresence Mobile.
