- With the improvement of people's living standards, mobile phones seem to have become their main tools. They not only use mobile phones, but also use them as social and entertainment devices to spend their free time. They use mobile phones not only at home but also at school, which seriously affects their studies and teacher courses. We know that many schools prohibit students from using mobile phones on the one hand, on the one hand for students’ learning, on the other hand, for better management of the school, and the school is in a normal system.

The advent of the 3G network era has greatly promoted access to the Internet. Users still need to rely on 2G networks to make calls and send text messages. 3G can only guarantee normal Internet access. 2G is still the backbone of voice and SMS services. The emergence of 4G allows people to watch videos smoothly, but even if they are using the newer 3g, 4g and 5g networks, users still use 2G networks when making calls and sending messages.
