Nexus 6P - No HD Voice and Wifi Calling

These are carrier features.

Wifi calling is not available for phones other than the iPhone 6 and 6S

 I hate to burst your bubble, but it's up to the FCC to approve use of these features

HD voice will have to be answered by @GLIMMERMAN76.

AT&T why NO HD Voice support on the Nexus 6P when the device supports it?  

 

Why do you only enable it on AT&T branded phones?

 

I don't want your phones with bloateware. I shouldn't be forced to buy an AT&T phone to use VoLTE, HD Voice, and WiFi Calling! Time to file a FCC complaint.

You want those features you will need to buy a ATT branded phone.

ATT is not giving google the code for HDvoice and they wont give it for WiFi calling

For Wifi calling the phone first has to be HDvoice compliant.

ATT is using different protocols than other carriers to implement there solution.

My ATT branded nexus 6 cant get HDvoice so there you have it.

You can file a compaint till your blue in the face your phone works and ATT does tell you on the BYOP page that not all features may work.

there is no carrier that offers coverage like ATT in this area.  well there is verizon but I dont want cdma.

At&t recently received a FCC waiver and does now allow wi-fi calling, Although currently at&t only allows Wifi Calling on iPhones 6, 6s, and the pluses (devices running iOS 9) with eligible rate plans.

Although Both the Motorola Nexus 6 & the Huawei Nexus 6P support Wifi-calling (as will most mid & high end phones coming out soon with Android 6 Marshmallow and above).

Currently Wifi-Calling on devices other than an iOS9 iPhone is supported only by Google Project Fi, Tmoble, Verizon and Sprint (Okay everyone except at&t).

AT&T handles Wi-Fi Calling a bit differently than others providers, with no or only limited handoff capabilities when going from Wifi to cellular (unless you are in a 911 call)

As far as HD-voice,... HD voice should be working dependant on your rate plan and the coverage in your area. See the HD voice coverage map: http://www.att.com/maps/wireless-coverage.html

Keep in mind as far as the HD-voice and true HD-voice service goes... ... We are talking about at&t, a company that called (rebranded) 3G HSPA+ a 4G service (they lied) and that in actuality was only half the throughput of every other providers true 4G. So if they actually have HD-voice or have "better than before" voice service and are just calling it (rebranding) HD-voice remains to be seen.

.

I was unaware they (at&t) were yet offering WiFi calling on anything other than iOS9 devices. I remembered reading the at&t WiFi calling press release/interview in last month's FierceWireless.

VoLTE (Voice over LTE) is not the HD-Voice codec. but the VoLTE standard supports the HD-Voice codec by default. It is possible to have HD-Voice without VoLTE, And you can also have VoLTE without HD-Voice.  

VoLTE is a standard, HD-Voice is a codec (compression and decompression) software algorithm.

I was not aware that VoLTE or HD-voice is limited only to at&t branded devices.

Although we are talking about at&t... ... ... don't like, nor trust them anymore than an unscrupulous used car salesman.

The HD-voice codec has been supported on the World Edition Nexus6 (not the at&t Nexus6) since Android 5.1,

If you have LTE and your HD-voice codec is not working you can try this:

Navigate to Settings > More > Cellular Networks and enable the toggle switch for "Enhanced" 4G LTE Mode. However, if the toggle is missing then follow the steps provided below:

1. Launch the Dialer app on your phone, and dial*#*#4636#*#*.
2. Choose Phone information.
3. Enable or select VoLTE Provisioned Flag.
4. Restart the phone.
5. Go to Settings " More " Cellular networks and toggle the switch for Enhanced 4G LTE Mode, and the HD Voice calling feature should now be activated on your device running Android 5.1 and above.
