Mobile market shares in Switzerland
At the end of 2025, Swisscom had 6,438,000 mobile customers in Switzerland, up 1.7% or +107,000 year-on-year. It gained 185,000 new contract customers (postpaid plans) but lost 78,000 prepaid customers.
Sunrise also recorded slight growth of 0.9% over the same period. This operator had 3,159,000 mobile customers at the end of 2025, gaining 82,000 customers in the postpaid segment while losing 55,000 in the prepaid segment.
Salt, meanwhile, recorded a significant increase in customer numbers, now standing at 2,254,000 customers (+6.3%). It added around 110,000 postpaid contracts during the year, plus 24,000 customers in the prepaid segment.
The figures from OFCOM’s Statistical observatory indicate that Swisscom had a market share of around 53.1% at the end of 2024, while Sunrise had 23.6% and Salt 17.7%. The market share for other operators was 5.5%.
For over ten years now, the market dynamic has been driven largely by the contract segment. Users of prepaid offers have increasingly been switching to postpaid contracts, with the proportion of contract customers thus increasing from 62.9% in 2015 to over 84.5% in 2024. The proportion of contract customers has continued to rise at each of the three network operators in recent months, and now stands at 90% at Sunrise, 86% at Swisscom and 82% at Salt.
In this segment, at the end of 2024, Swisscom held some 54.2% of the market, Sunrise 24.7%, Salt 17.3% and other operators 3.9%.
