When will Europe allow phones (to communicate) on planes?
There is a similar ruling since last week. 

The use of electronic equipment as long as they are in "flight mode" during all phases of flight was already allowed in Europe by EASA since November 2013.

Since last week (26 November 2014) EASA also allows phones to be on and connected throughout the flight. This allows for WiFi services, phone services and Bluetooth battles during the flight. 

Before allowing the use of these electronics in flight, airlines have to assess the impact of the signals transmitted by the mobile devices on the aircraft, ensuring aircraft systems are not affected. For this reason mobile communication will not be allowed by all airlines on all flights at once.
