This is the conclusion of a survey of OpenSignal, which analyzed the quality of voice calls over 3G and 4G in 80 countries. In the global ranking, Brazil was in 39th position, with 77 points on a scale from 0 to 100.

The study also divided the experiences with voice calls on 3G networks, in which Brazil has 70.9 points, and 4G, 79.9 points. The assessment is that, here, calls in apps like WhatsApp, Skype and Messenger work, but have problems such as hissing, low volume and interference.

In comparison with other Latin American countries, Brazil’s overall score is only lower than that of Uruguay (78.6 points) and Puerto Rico (78.5 points). According to the survey, two-thirds of the countries in the region have a poor or very bad rating.

On the other hand, 13 of the top 20 countries are in Europe. The ranking is led by Belgium (82.6 points), the Netherlands (82.4 points), Denmark (82.2 points), Slovakia (82.1 points), and Finland (82 points).

None has quality considered “excellent” or “very good”. According to OpenSignal, this is due to the limited capacity and latency of 4G networks. The company believes that 5G will allow more users to have voice calls with above average quality and with less latency.

The survey was made from 57 billion measurements made on 23.8 million cell phones between June and August. Based on criteria from the International Telecommunication Union (ITU), OpenSignal has created eight levels for call quality.

They indicate whether the level of calls via mobile networks is Excellent (95 to 100 points), Very Good (87 to 95), Good (80 to 87), Acceptable (74 to 80), Bad (66 to 74), Very Bad (60 to 66), Unintelligible (45 to 60) or if it is impossible to communicate (0 to 45).
