• NTT Communications China provided training to Sony personnel in China to facilitate a smooth introduction.
• Schedules were fully managed in countries where the service would be offered in cooperation with local carriers.
• Close coordination with vendors helped to accelerate the introduction of compatible devices.

• Flexibility to launch new businesses quickly.
• Reduced network TCO.
• Unencumbered communication for close, group-wide collaboration.
