Coverage
Our Brazil RDD sample connects with 220 million individuals for your research.
In Brazil, mobile phones have become the preferred method of communication over landline numbers. With the rise in technology and accessibility to mobile devices, landline usage has been steadily decreasing in recent years. According to data from the National Telecommunications Agency (Anatel), in 2019, there were over 228 million mobile lines in Brazil, compared to just 35 million fixed lines. This significant difference highlights the shift towards mobile phones as the primary means of communication in the country. The high penetration of mobile phones in Brazil can be attributed to several factors, such as the affordability of smartphones, widespread coverage of mobile networks, and the convenience of having a portable device for communication. Additionally, mobile phones offer a variety of features beyond just calling, such as messaging, internet access, and social media connectivity, making them more versatile and appealing to consumers. Overall, the prevalence of mobile phones in Brazil demonstrates the changing telecommunications landscape and the increasing reliance on mobile technology for communication. As mobile devices continue to evolve and become more advanced, it is likely that the trend of mobile phone usage will continue to grow, further overshadowing the use of traditional landline numbers in the country.
