    • Support for Wifi and mobile networks, providing world-wide availability via your CERN fixed number
    • Low data consumption (less than 1MB per minute) for cost-efficient communications when on mobile networks
    • Minimal battery consumption thanks to app wake-ups via Push Notifications
    • In-call network handover support (resiliant to network changes)
