Coverage
Our Serbia RDD sample connects with 7 million individuals for your research.
In Serbia, landline numbers are still being used but mobile phones are more frequently used. According to the latest data from the Serbian Regulatory Agency for Electronic Communications and Postal Services (RATEL), the number of mobile phone users in Serbia has been steadily increasing over the past decade. In fact, mobile penetration in the country reached over 150% in 2020, indicating that there are more mobile phone subscriptions than there are people in Serbia. On the other hand, the number of fixed-line telephone subscribers has been declining in recent years, as more and more people choose to rely solely on their mobile phones for communication. This trend is not unique to Serbia, as many countries around the world are experiencing a similar shift towards mobile telecommunications. While landline numbers are still in use in Serbia, it is clear that mobile phones are the preferred choice for communication for the majority of the population.
