It is reported that a Japanese company will sell smartphones that cannot be used at night to primary school students. It is reported that the research and development of this mobile phone refers to the opinion of the Guardian, "I hope students have a mobile phone for easy contact, but I am worried about excessive use."

It is reported that Tone Mobile, the mobile communication operator of Japanese company culture convenience club, will release this Tone M 1 7 mobile phone from August/day, with a price of 34,800 yen excluding tax.

According to the factory settings, if the initial user is under the age of 12 at the time of registration, the mobile phone will be automatically locked between 10 at night and 6 am, but the locking period can also be adjusted or unlocked according to the guardian's judgment.

In addition, the use time of major applications such as communication application lines will also be limited. In order to prevent it from being used during study, the mobile phone is also equipped with the function of automatic locking once it enters a preset place such as school.

I hope it has such good functions.
