Coverage
Our Guinea-Bissau RDD sample connects with 1 million individuals for your research.
In Guinea-Bissau, mobile phones are more frequently used than landline numbers. The country has a limited infrastructure for fixed telephone lines, and as a result, mobile phones have become the primary communication device for the majority of the population. According to data from the World Bank, mobile phone penetration in Guinea-Bissau was at 69% in 2019, while landline penetration was only at 0.3%. This stark contrast between mobile and landline usage further emphasizes the dominance of mobile phones in the country. Due to the ease of accessibility and affordability of mobile phones, they have become the go-to choice for communication for both personal and business purposes in Guinea-Bissau. With the increasing popularity of mobile phones, it is unlikely that landline numbers will see a resurgence in usage in the near future. Mobile technology continues to advance, making it even more convenient and versatile for users, solidifying its position as the primary communication tool in the country.
