Dealing with Spam Email and Nuisance Calls

We continue to strengthen anti-spam email measures and functions to ensure customers can use i-mode Mail with total peace of mind. These measures are being carried out under a basic policy of not allowing spam email to be sent, blocking mail with unknown addresses used to collect mail addresses, and providing settings to prevent spam email from being received.
For example, in fiscal 2009 we began selling phone models with functions that allow receive/block settings for spam emails. The number of settings was also increased from 40 to 120. In addition, on 13 models launched from winter 2010 to spring 2011, we added a spam email reporting function. The user just needs to select the spam message, select Report Spam on the submenu and then press the send button. This makes it possible to provide spam email information to DOCOMO.
Anti-spam email measures that DOCOMO has implemented have had some success, but spammers' trick and spam patterns are becoming increasingly diverse and sophisticated on nearly daily basis, so we continue to receive inquires and questions from customers. We plan to continue strengthening measures that make using mail a more pleasant experience for customers.

The Nuisance Call Blocking Service is provided as a countermeasure against nuisance calls and prank calls.
When a call comes in from a number preregistered as a nuisance caller, the service responds with an automated voice message that states it is not possible to connect to the person being called. This automatically ends the call without the call being registered in the user's call history.
