The “mimamori keitai 005Z”, or the “protection cell phone” (my translation) is set to be released in March 2011. The phone has a crime prevention buzzer built in, and only has 1 button on it.
The display is a tiny 1.2 inches, and was designed with young children in mind. It will also be equipped with a GPS locator that parents can use to find it. In addition to the buzzer, if something happened, the phone would also automatically dial the emergency number programmed into it, presumably that of the guardians or parents of the user.
The phone can be used to make calls, but only calls to pre-approved, pre-programmed phone numbers. Softbank will offer a special monthly plan for the phone, expected to be about 490 yen (US$5.85) per month with a 2 year contract.
