The change of mobile network coverage on the French part of the CERN site will take effect on 29 August and not on 11 July as previously announced. 

From 29 August, the Swisscom transmitters in France will be deactivated and Orange France will thenceforth provide coverage on the French part of the CERN site. 

This switch will result in changes to billing. You should also ensure that you can still be contacted by your colleagues when you are on the French part of the CERN site. Please consult the information and instructions in this official communication.
