Step-by-step explanation:
Text messaging is a significant component of mobile phone usage in emerging economies, despite the assumption that most people in these countries cannot read or write. In developing countries, such as those in Africa, mobile phones have revolutionized communication and provided access to banking services, internet resources, and market information. In fact, there has been a fivefold increase in mobile phone access in Sub-Saharan Africa, and more than a third of people in the region can access a mobile phone.
Additionally, the rise of newer communication methods, such as texting, has resulted in the replacement of older ones like phone conversations. Text messaging has become the primary way to communicate for many people, especially young individuals, due to its convenience and ease of use.
