The best performing voice calls, on the other hand, are concentrated in Europe, which houses 13 of the 19 best ranked countries. The list led by Belgium (82.6 points), Netherlands (82.4 points), Denmark (82.2 points), Slovakia (82.1 points) and Finlndia (82 points).

No country has achieved "excellent" or "very good" quality. According to OpensignalThis is due to limited capacity and latency of 4G networks, which causes delays and variations in the signal. The company believes that 5G will allow more users to have access to above average voice calls and less latency.

The survey was based on more than 57 billion measurements in 23.8 million mobile phones worldwide between June and August. Based on the parameters of the International Telecommunication Union, Opensignal has created indexes to quantify the quality of voice calls over the 4G mobile network. They indicate whether the link level is excellent (95 to 100 points), very good (87 to 95), good (80 to 87), acceptable (74 to 80), poor (66 to 74), very poor (60 to 66 ), unintelligible (45 to 60) or unable to communicate (0 to 45).
