NTT DoCoMo Inc. unveiled a new smartphone Thursday designed to shield young customers from hazards lurking on the Internet.

The new SH-05E smartphone, produced by Sharp Corp., prevents the user from accessing harmful websites, limits calls and email messages to sources on a preregistered list, and restricts the types of applications that can be downloaded.

As the smartphone boom expands, the trend is expected to pick up younger consumers as well, many of whom use conventional mobile phones. The new Sharp model addresses those concerns, said Takeshi Saito, director of DoCoMo's marketing division.
