Coverage
Our Angola RDD sample connects with 14 million individuals for your research.
In Angola, landline numbers are not as commonly used compared to mobile phones. According to data from the International Telecommunication Union, the mobile penetration rate in Angola was at 46.07 percent in 2019, while the fixed lines penetration rate was only at 1.63 percent. This indicates that a majority of the population in Angola relies on mobile phones for communication rather than landline numbers. The convenience and accessibility of mobile phones, as well as the rapid expansion of mobile networks in the country, have contributed to the popularity of mobile phones among Angolans. With the increasing affordability of mobile devices and mobile plans, more people are opting for mobile phones as their primary means of communication. As a result, landline numbers are becoming increasingly obsolete in Angola. While some businesses and government offices may still use landline numbers, the general trend in the country is towards the widespread adoption of mobile phones for communication.
