So long, 3G
Around 20 years ago, the third mobile generation, 3G, heralded the start of the mobile Internet age. What was once a ground-breaking mobile generation is now 20 years old and no longer efficiently meets the needs of today’s customers. By the end of 2025, therefore, Swisscom will switch off 3G completely, freeing up mobile network resources for more powerful, state-of-the-art technologies and ensuring that our network is fit for the future.
Good reasons for the 3G shutdown
A mobile phone journey through time
The first mobile phones hit the world almost 30 years ago. Within a short time they became the smartphones that have become an integral part of our everyday lives.
Free SMS enquiry offers clarity
There are 4G mobile phones around which still use 3G for calls, even though they are 4G-enabled. These devices will no longer work after the shutdown. By sending a free SMS with “3G” to 444, you can easily check which technologies your phone supports.
