The expansion of our 4th and 5th generation (5G) mobile network has advanced significantly. The Sunrise 4G network covers a much larger area than the 2G network, with over 97% coverage. Furthermore, Sunrise already provides over 1,000 towns and cities in Switzerland with high-speed 5G (up to 2 Gbit/s) and over 96.7% of the population with basic 5G (up to 1 Gbit/s).

The technically outdated mobile communications standard of the 2nd generation (GSM, GPRS, EDGE, HSCSD) is currently still in operation, but is practically no longer used. Therefore, the 2G network will be deactivated as of January 3, 2023. This will have the following impact on your Sunrise Business product:



  • Calls

  • National emergency call service 112

  • SMS: Sending and receiving

  • Data transfer (GPRS, EDGE, E-EDGE, HSCSD)

The aforementioned services will continue to operate via 3G, 4G and 5G from January 3, 2023. Devices that only support 2G must be replaced with devices with a modern mobile communications standard (4G/5G).

The second-generation mobile communications standard (GSM, GPRS, EDGE, HSCSD) is technically outdated and practically no longer in use. Compared to more modern technologies (4G and 5G), 2G is characterized by relatively low efficiency and uses more resources, such as bandwidth and electric power, per transmitted data unit. Given that mobile Internet usage and demands for increased data rates are constantly growing, carriers are relying on modern mobile communications standards such as 4G and 5G in particular.

2G is currently only supported by Sunrise. Sunrise will continue operating the 2G network until January 3, 2023.

We recommend that you switch to a newer technology such as 4G or 5G. This will allow you to stay technologically up-to-date and be well equipped for the future.
