Hit parade of mobile network providers
In 2016, comparis.ch conducted a survey on customer satisfaction with the mobile communication providers in collaboration with the market research institution, GfK. A total of more than 1100 persons from all linguistic regions of Switzerland were surveyed. They rated the following criteria: the quality of calls, the satisfaction with the hotline and the mobile internet, the comprehensibility of customer information, the network coverage, and the price.
Rating scale: 5.5-6 = very good, 5-5.4 = good, 4.5-4.9 = satisfactory, 4-4.4 = adequate, below 4 = poor
All answers from one respondent about a provider are taken to calculate the total rating from the same respondent. A provider's final rating corresponds to the rounded mean value of all these total ratings. The final ratings as given by comparis.ch are based on the Swiss school grading system. )
