Switching on your mobile phone while travelling , is that possible?

I have recently read that du the new  telecom operator in UAE will be introducing a new service that enabels its clients to use thier mobile phone during the flight ! isn't that geat ?

So you will access your mobile  and  instantly start making and receiving calls in addition to sending and receiving text messages.

And don't worry using du's service  has no impact on any of the aircraft systems.
