First, it is not relevant 3G or Wifi - HD Voice is a cell support feature, it is not using you data connection.
Nexus 4 supports HD-VOICE: http://en.wikipedia.org/wiki/List_of...using_HD_Voice

Anyway, there is not a simple answer. Your provider needs to support HD Voice on Nexus 4 (in particular.)
Orange Israel, for example, support HD Voice on Nexus 4 with Android 4.2.2 at maximum. If you upgrade to 4.4x
it will stop working and there is no option to enable it.

BTW, just saw that in local forum we have an official reply from LG:

"Officially and Originally, Nexus4 does not support the AMR-WB even though it was worked well in previous version.

AMR-WB has not been supported by H/W but by S/W and it makes performance issue during PTCRB test that’s why we cannot pass the PTCRB test with enabling AMR-WB.
But, Nexus4 needs a PTCRB certificate for Global market and we decided to remove the AMR-WB feature from the S/W side."
