Swisscom Mobile has become the latest European operator to enable HD Voice technology. From today the operator is offering HD Voice over its UMTS network, potentially reaching 93% of the population.
Customers need a compatible phone, with Swisscom proposing the the Nokia 800 Lumia, HTC Sensation XL and Sony Ericsson Xperia arc S as “particularly equipped”.
If both phones are on Swisscom’s UMTS network, then the conversation will be automatically transmitted in HD Voice. No extra charge for the service will be made. .
