Simple operation

Old people don't need complicated mobile phones. It is best to use some commonly used functions. If old people have operated them before, they are familiar with them. Old people who haven't had surgery are easy to get started.

Health and environmental protection

After middle age, with the decline of physical function, there will be phenomena such as decreased vision, decreased hearing, shaking hands, physical fatigue and poor sleep quality. Therefore, the elderly mobile phone has the characteristics of large font, big ringtone, big buttons and loud voice (or hands-free support). In addition, the mobile phone radiation value (SAR value) is low (the national mobile phone radiation value is 1.0, and the elderly mobile phone radiation value is basically around 0.5). Because the elderly are more sensitive to mobile phone radiation than young people, long-term exposure to mobile phone electromagnetic radiation will lead to headache, dizziness, insomnia, dreaminess and hair loss.
