After a trial in June, Orange has officially launched High Definition or HD mobile phone calls nationwide.

The merger between Orange and T-Mobile has become a reality. While both companies will essentially keep their own identities, at least for the time being, the new company will be called Everything Everywhere.

If you have ever been fed up with the call quality when talking to someone on your mobile phone, then you may be interested in Orange’s new trial. The network company is to try out a new High Definition (HD) device called HD Voice.
