Advances in digital technology have made cell phones an important part of children’s lives, including as a means of communication, learning, and accessing information. However, uncontrolled cell phone use among elementary school-aged children has the potential to affect their study habits, physical activity, social interactions, sleep quality, and physical and psychosocial health. On the other hand, children’s understanding of cellular network technology, radiofrequency waves, and the healthy and responsible use of cell phones still needs to be improved. This community service activity aims to enhance the knowledge, awareness, and attitudes of students and teachers regarding the wise use of cell phones while prioritizing children’s health and development. The activity was held at SDIT Al-Firdaus in Banjarmasin and targeted sixth-grade students, teachers, and school administrators. The methods used included health education, interactive presentations, discussions, question-and-answer sessions, and reinforcement of healthy cell phone usage habits. The material covers an introduction to 4G and 5G network technologies, basic concepts of radiofrequency waves and electromagnetic exposure, setting limits on cell phone usage, keeping devices at a safe distance from the body, taking breaks from screen time, and the importance of balancing digital activities, learning, physical activity, rest, and social interaction. The program also reinforces for teachers and school administrators the importance of guidance and fostering a healthy culture of digital literacy. This community service initiative is expected to raise students’ awareness of the importance of using technology in a positive and responsible manner, as well as to encourage schools to play a role in creating an educational environment that supports children’s health and development. This initiative also supports the achievement of the Sustainable Development Goals (SDGs), particularly quality education, good health, and the development of human resources capable of adapting to technological advancements.
