Mobile phone for the elderly refers to a kind of mobile phone used by the elderly. With the improvement of people's health level and the extension of population life, the proportion of the elderly in the population is increasing. Mobile phones for the elderly are widely used by the elderly, which has an important impact on the popularity of telecommunications terminals in the country, allowing the elderly to fully experience modern life. In the fierce mobile phone competition market, enterprises can gain an advantage in the competition only by relying on accurate mobile phone market segmentation and designing practical and easy-to-use mobile phones according to user needs. The introduction of mobile phones for the elderly is no stranger to most people. Today, the mobile phone market is more and more subdivided, and the mobile phone market for the elderly has become more and more rampant from scratch.
