High values for the crowdsourced network coverage for voice and 4G once more emphasise the good network performance in Switzerland. Also the “quality of coverage“ (how often the customers could have actually used a respective network technology) is pleasantly high. Swisscom shows somewhat higher top values for the effectively achieved data speeds. Here, Sunrise and Salt are on a par, but behind Swisscom. For „Data Service Availability“, we have extended the observation period to last from May until November 2018. Here, Sunrise shows a convinding zero observed degradations. In the Swisscom network, we identified only one event with a length of up to one hour in August 2018. In the Salt network, we recognised degradations on eight days over a total of 22 hours in the Salt network.

The overall 2019 winner in Switzerland is Swisscom – with a razor-thin lead of just one point. The market leader outperforms its strong rival Sunrise thanks to the data and crowdsourcing disciplines. However, its voice results fell marginally behind in comparison to the previous year. But all in all, Swisscom deservedly claims the total victory of this test and receives the grade “outstanding“.

As in the year before, Sunrise scores ahead of its rival Swisscom in the voice discipline. The results of the data measurements and the crowdsourcing analyses are also top-class. We especially did not observe any degradations at all in Sunrise‘s network between May and November 2018. Scoring only one point behind the test‘s winner, Sunrise achieves the second rank and also the grade “outstanding“.

Salt scores third, but shows the most distinct improvement over previous year‘s results. Both in the voice and in the data disciplines, the successor to Orange achieves better results than in our measurements conducted one year ago. Even if the crowdsourcing reveals a comparatively high number of degradations, Salt thus rises from last year‘s grade “good“ to an impressive “very good“.
