Modernisation of the mobile network

Goodbye 2G –
hello 5G

As technology advances and accelerates, the expectations of our customers grow. That is why we continue to invest in improving our network. In so doing, we sometimes have to part with technologies that have become outdated. By the end of 2020, we will therefore be replacing the old second mobile generation, 2G, with more modern technologies such as 5G. This document covers the most important information about the planned phase-out.

Everything you need to know about 2G switch off.

From May 2019, we will be contacting all customers still using an old 2G mobile phone to inform them of the impending switch off. We will help to make sure that it is as straightforward as possible to switch to a new device. Did we contact you by letter or SMS? Give us a call or visit us in a Swisscom Shop.

What is happening and when?

By the end of 2020 it will no longer be possible to use 2G devices on the Swisscom network.

What should I do?

Check whether your device is affected and replace it in good time.
