WhatsApp is a popular messaging app in Mexico due to its affordability and ease of use. In a country where half of the population still lives below the poverty line, WhatsApp is one of the most economical ways for people to communicate. It is also a great way for people to stay connected with their family and friends, especially people living in rural areas where they may not have access to traditional telecommunication services. Additionally, it offers free video and audio calls, which are a great way to communicate with each other even if they are not in the same place. With its wide range of features, WhatsApp is an essential tool for many people in Mexico.
