Bye bye 2G
After almost 30 years, 2G has finally had its day. The outdated mobile technology was switched off for good in early April. It has made way for new technologies that are much more powerful, reliable and sustainable. For four years, Swisscom has been helping its customers to switch to new devices, to ensure that they can continue to use the best network in Switzerland.
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.
The most common questions
Here you will find the most important answers for the renewal of the mobile network.
Why was Swisscom's 2G network switched off?
2G mobile technology, which is almost 30 years old, is no longer up to date: it can no longer handle customers’ increasing data demands, the more modern mobile technologies provide much better voice quality and the newer mobile technologies are much more energy efficient.
When did Swisscom switch off the 2G network?
Swisscom's 2G network was finally switched off at the beginning of April 2021. Since then, it has not been possible for any device to access it.
Do I need to change my device (mobile phone/machine application)?
If you have experienced a loss of performance for basic functions such as telephony, data transmission or SMS, we recommend switching to an up-to-date device that is at least 4G-capable.
My device (mobile phone/machine application) has not been working as usual since was 2G switched off. Is it sufficient to insert a new SIM card?
No, replacing the SIM card won’t change anything. We recommend switching to an up-to-date device that is at least 4G capable.
What will happen to my old mobile phone?
Swisscom promotes various projects for sustainability. If you wish, you can donate your old mobile phone to Mobile Aid at a Swisscom Shop, for example. Find out more at: www.swisscom.ch/mobileaid
My 3G device does not run any more or is restricted, why is that?
Up to now, some 3G devices only used the 2G network, as they do not technically support the 3G 900 MHz frequency. The fact that 2G is switched off means that these devices no longer have a network and will need to be replaced.
My 3G/4G device no longer works, what could the reason be?
Please check in your device setting whether the network selection is fixed to 2G. We recommend setting this to "automatic network selection".
