Dubai carrier du says it has upgraded its network to support HD voice on its HSPA network. It isn’t clear if the service is commercially available or still in trials.
The August 31, 2012 Global mobile Suppliers Association (GSA) report says du was still in trials, but several recent pieces out of the region quote company officials saying its existing 3G HSPA network has been upgraded to support HD voice.
Du is also in the process of expanding its LTE network. No indication when Voice over LTE (VoLTE) will be supported.
