Customers use DOCOMO services with confidence thanks to the company's network center, which monitors and controls the extensive DOCOMO nationwide network on a nonstop 24/7 basis, thereby enabling the company to respond rapidly to any unforeseen situation.

DOCOMO sets up its mobile phone base stations with the permission of the Minister of Internal Affairs and Communications. New mobile phone models are confirmed to be in full compliance with all required technical standards before sale. After extensive testing, exposure to mobile phone radio waves could not be connected with any effect on human health. Going forward, DOCOMO will continue to comply with all pertinent laws, conduct safety tests and cooperate with related organizations on a proactive basis.

To help children use mobile phones safely, DOCOMO's Access Restriction Service blocks access to sites harmful to children. Another safety service, imadoco search, allows parents to easily confirm their child's location via i-mode or a PC. Through these and other services, DOCOMO enables customers to achieve greater peace of mind through advanced mobile communications.
