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 The outdated mobile technology was switched off for good in early April.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.
