Only three mobile service providers in Switzerland – Swisscom, Sunrise and Salt – operate their own mobile networks. But there are numerous additional mobile service providers that offer their own mobile plans, but make use of the physical networks from the three network operators.
Many mobile service providers are subsidiaries of either Swisscom, Sunrise, or Salt. Some are joint ventures between major retailers and mobile service providers.
Some mobile service providers operate largely independently of the three network operators, but use the mobile networks from Swisscom, Sunrise, or Salt. These service providers include Digital Republic, Galaxus Mobile, Spusu, and Quickline.
