Lufthansa will soon bring inflight mobile phone capability to passengers, after receiving certification for AeroMobile’s “eXPhone” GSM connectivity system…The German carrier says it has started “testing the performance” of the eXPhone system in-flight.

A total 71 Lufthansa aircraft now offer the Internet service, which is branded as FlyNet by the airline…Lufthansa previously said that passengers would be able to use inflight GSM for text and data use, but not voice. The carrier already tells passengers not to use FlyNet for VoIP services.
