    I have tested this feature extensively and the result is that Galaxy Nexus does support AMR-WB but I was able to make it work only when using some particular basebands. As far as I can tell it works when you use some of the korean, japanese or australian basebands. However, I ran into issues which I was not able to resolve. These issues included occasional call drops or sound dropouts as the phone sometimes had to switch from WB to normal mode because of signal quality. I am not sure whether the cause is rather low quality of T-Mobile network here in Czech republic or if it is a problem of the phone because since I bought this phone I started to experience these issues and even after I got a replacement they did not seem to go away. Because these issues happen more often when using AMR-WB I finally switched to some other baseband that does not support AMR-WB but seems more stable with my operator's network.

    What about international Samsung Galaxy S3 on TMobile network? Reply

    The Nexus S, Galaxy Nexus and Nexus 4 have the capabilities for HD Voice. WIND Mobile in Canada (my carrier) have HD Voice enabled for these devices and they use AMR-WB. Reply

    So I'm in the service mode on my Galaxy S 3 (*#0011#). Should I be seeing something in here to validate that I'm picking up AMR-WB? I do see an entry here that says:

    "SpeechVER: EFR FR not used"

    No idea if that's related or not..

    ok, I disconnected from WiFI and now I DO see "AMR 12.2 kbit/s" at the bottom of the service mode page. So I take it I'm good then?

    This does bring another question though: If I'm connected to a WiFi hotspot, am I NOT getting HD voice? If yes, I assume that means that AMR-WB voice goes over the data network? (packet data instead of circuit-switched??)

    AMR-WB is just a codec and setting for voice calls. It still has to go through your carrier's network. If you were using some SIP service then it would be able to transfer the data via wifi but this does not concern standard phone calls. Reply

    Do these calls ride on thier HSPA+ network - wht happens to two HD capable devices outside that environment; also +1 on the Wifi question Reply
