Change of Mobile Telephony Operator

Following a call for tenders issued in 2014, CERN has agreed a contract with Swisscom for the provision of mobile telephony services from 1 July 2015.

The Sunrise equipment on CERN sites will therefore be switched off from this date and people with a CERN mobile subscription will need to exchange their Sunrise SIM card for a new one from Swisscom, with a new mobile number (the last 4 digits will remain the same). We cannot give further details at present as we are still finalising arrangements for the deployment of the new network with Swisscom, but detailed information on the steps to be followed will be given well in advance of the changeover.
