first smartphone,
children questions,
Parents' worries Q&A

As children reach the upper grades of elementary school, more and more families are thinking about getting a smartphone soon. We will introduce Q&A about children's questions and parents' concerns about the first smartphone.

children's questions
(1) A friend once asked me, "Don't you have a kid's mobile phone?"
② What is the number one reason why you want to have a smartphone in elementary school?

(1) According to a survey, 35.9% of elementary school students own smartphones (annual government survey, 2018 data).
(2) As for the reasons for wanting to own one, many girls want to communicate with their friends, and many boys want to play games.

I like to look up various things on the Internet, but my parents are worried that I will use my smartphone too much if I have one. Any solution?

First of all, let's talk with the whole family. As one solution, there are cases where a rule is made that children should be used within the reach of their parents at home and not brought into their own room. Also, there are families where the usage time is set and the parents take care of the rest.

parent's worries
① Please tell us the timing and reasons why parents want to give elementary school students smartphones.
(2) I can't help but think about game addiction and adverse effects on my eyes. In addition to making rules at home, is it possible to restrict usage?

① The first thing is to be able to contact your child at any time when you go to cram school and act alone. Also, there are many reasons to "know where you are".
②There is a function that shows the usage status of apps and the Internet, and it is possible to restrict usage with this. Parents and children should decide on a rule, such as playing games for one hour a day or not using email after 10 pm, and using it based on that. I think the important thing is to discuss and decide what, when, and how you will use your smartphone before you own it. Just saying "no" is enough to make you want to quit.

① I am concerned about the safety of smartphones. They worry that they might get into trouble by connecting with strangers they don't want.
② I have three children, and when each of them has a smartphone, I am worried about the price.

① There is a function to block calls and emails from strangers and unregistered people. It is safe to register only those who are approved by parents in the phone book.
(2) Not long ago, the monthly usage fee for one smartphone was quite high, but now service companies like ours, which are collectively called "cheap smartphones," have appeared, and low-priced plans have also appeared. increase.
You can check it easily from the smartphone charge simulation, so please try it.

J: What are the features of COM MOBILE?

We prioritize safety and low cost, so we offer free "filtering" that restricts access to sites inappropriate for children, lower monthly fees, and more. The following points can be mentioned. For families who are unsure about the initial setup, we can come to your home and provide peace of mind support if you wish, and of course support is also available at each J:COM store.
