Key Findings

Japan, the Netherlands and South Korea ranked at the top in our group video calling analysis

In our group video calling analysis — which included 75 countries — Japan, the Netherlands and South Korea shared the first position scoring 68.7 points, 68.6 points and 68.2 points, respectively. In our analysis, the results represent the likelihood that all smartphone users participating in a group video call of between two and eight people will have an adequate experience that will allow the call to run seamlessly, considering real-world measures of both the video and audio components of all the users on the call. We quantify group video calling on a 0 to 100 point scale, where the higher the scores, the higher the likelihood that all smartphone users in a group call had an adequate experience.

European countries dominated the top ranks

Europe accounted for twelve out of the top 20 countries, although none of the “big five” — France, Germany, Italy, Spain and the U.K. — figured in the top 20; by contrast, Russia was the only European country in the bottom 20 countries of our analysis. Of the remaining 8 countries in the top 20 list, six countries were from the Asia Pacific region — Australia, Japan, New Zealand, Singapore, South Korea and Taiwan, and only Qatar and Uruguay came from the remaining regions.

Group video calling scores were up to 42.3% higher on 5G than on 4G

We compared our group video calling scores observed on 4G and 5G networks in nine leading 5G countries, including Australia, the U.S. and South Korea. Our group video calling results measured on 5G networks scored between 7.3 points and 20.2 points higher than what we observed on 4G networks in most countries — which represented a relative increase of between 11.9% and 42.3%.

Congestion at busy times of day hurts the group video calling experience

Opensignal analyzed how our group video calling measure varied across the hours of the day. Our data showed patterns suggesting that congestion was indeed a factor affecting the likelihood that all users participating in a group video call had an adequate connection. We observed this fluctuation occured across most countries, but we also observed that countries achieving higher group video calling scores generally had a more consistent experience across the day compared to countries with a lower score.
