Smartphones are heavily dependent on the internet and consume much more Data than the traditional mobile phones (push e-mail option, download of the whole email with attachments, free applications etc.). Please note that the roaming charges for Data transfer can be expensive depending on the country, especially outside neighbouring countries (France, Germany, Italy, Austria). More details on tariffs are available here: Communication and Data transfer tariffs.

The best way to avoid excessive and accidental Data usage is to disable the Data Roaming AND location services and unblock it only if needed:

iPhone

Go to Settings -> General -> Cellular-> Data roaming: OFF

Then go to Settings -> Privacy -> Location Services -> OFF

You can control your Data transfer usage in the menu: Settings -> General -> Usage-> Cellular Network Data

Samsung

Galaxy : Go to Settings -> Connections -> More Networks -> Mobile Networks -> Uncheck the option ”Data Roaming”

The printed copy of this request is given for signature to the representative of the COMPANY and the EDH request is sent by the CERN person in charge for the contract.
