I'm curious to find out if there's a way to know for sure if/when HD Voice is actually working during a voice call apart from sound quality or coverage map. I think it should be and maybe it is but it doesn't really sound like it. We have an iPhone 7 and an iPhone SE both with LTE Voice and Data ena

Does the Samsung Galaxy S4 SGH-I337 support VoLTE  aka  HDVoice ?

[Subject edited for better exposure] Okay. I am just a 14 year old child. I got an iPhone 6 plus just a few days ago. When I went to settings on my iPhone, I saw a feature that allowed me to use LTE for voice calls. However, I have no idea if it would count against my data usage or my minutes becaus

Hi, I have an iPhone XR purchased about a month ago (by my dad)there are four phones on our account, me, mom, dad, grandmaum a few days ago someone reported an iphone X that was "stolen" in our account and locked me and my grandmas phone from accessing the networkhowever we resolved it and now data

I don't expect an answer here, I mean I've gone back and forth with ATT "support" for a while on this one and I am at the point where I'm done.  But, I wanted to state this in the public forums because I know (based on threads here) that I'm not the only person annoyed by the ignorance set forth by

Has anyone had success with tier III support enabling these features on a compatible (just not AT&T sanctioned) device? I'm a bit preturbed that the AT&T BYOD page, when putting in the IMEI of my new Sony Xperia Z5 (E6653) says "Congratulations, your phone is compatible" in big bold letters .... but

When upgrading from a unlocked phone to an ATT branded phone, do you have to do anything besides swap the SIM?  The ninth and tenth digits of my SIM card are 27 which means it should be VOLTE capable.   Will the system automatically update the IMEI to enable advanced features?  I know there is a por

I understand the initial roll out of AT&T HD Voice supported only the Galaxy S 4 Mini, and that additional AT&T LTE phones may received firmware updates to add Voice Over LTE compatibilty. My questions relate to non-AT&T phones.  I currently use a Sony D5803 Z3 Compact.  This phone was designed by S

We have an AT&T branded S9 and an unlocked/non-branded S10e U1. The S10e doesn't list Wi-Fi Calling, Video Call and Real Time Text. Based on another thread I thought these features were just enabled on U1 versions. So why don't I see those settings on the S10e? Is there a way to enable it?

Hello, As we are approaching 2019... is there any plans for VoLTE/Wifi Calling coming to prepaid anytime soon?  Thanks, Tom

This month I had a lovely adventure with a Lumia 950 XL that almost melted due to overheating. That's my problem, and the 950 XL is being replaced. Along the way I somehow lost call forwarding and voice over LTE registration on my original Lumia 830; one I bought from an AT&T corporate store (not an

HTC claims that the U11 device supports AT&T network but a simple but useful feature is VoLTE which was supported by last year flagship HTC 10 even when AT&T didn't carried the device themselves, I have been back and forward with AT&T support and every time they update the IMEI on the system with my

My Questions is why is at&t the only provider that does not support VoLTE or HDVoice for non at&t branded Phones. I bought the Google Pixel XL from the google play store and a LG Sport Watch from at&t. I can not use at&t's NumberSync Service because they will not support my Pixel with VoLTE and HDVo

I have a iPhone 7 Plus of Model A1785 and when I tried to enable wifi calling on the iPhone, it shows the following error:"We can't turn on WiFi calling for your account. Think this message is a mistake? Ask the person who can make account changes to call us. The number is 800.331.0500. (EDS0008)". 

I am currently on ATT's prepaid multiline plan. I am considering purchasing a previously used iPhone SE and putting it on the plan. I need to know the following:1. Is the iPhone SE model capable of VoLTE, wifi calling, number sync, and call protect on a prepaid plan?2. Is there a difference in softw

Hi all, Does anyone have an Eta for when GoPhone subscribers could expect VoLTE support, Wi-Fi calling and access to the My Att app? Currently the My Att app redirects to the mobile site of paygoonlie.com. Thanks

Someone help! I have brand new s8+.  I can't get my account to let me use hd voice/enhanced LTE at all, Blocks outgoing calls from happening (voice recording can't make a call at this time when I try) .  I'm waiting for level 4 tech with customer support for 2 weeks and haven't called me. Will list

I've spoken to 2 AT&T Reps and 2 differnt AT&T corp. Retails stores and so far no one seems to even understand HD voice. Its not working on my iPhone 6+ even though the coverage map for Portland,OR confims HD Voice coverage. I've concluded that AT&T is advertising HD Voice in Portland, OR but its no

I have two questions about my Galaxy S5 from AT&T.1: When will AT&T relaease Android 5.0.1 Lollipop for the S5?  Can I at least have a ETA of the update?  (See http://bit.ly/1xhPpCu) 2: The Galaxy S5 is capable of doing HD Voice (VoLTE), will AT&T's Lollipop update enable this feature for S5 users?

So I bought a Xiaomi MI 9 Global after ensuring it will work with AT&T. Although it does work, including LTE I've clocked in the 100Mb range, I have no voice and data simultaneously, no VoLTE and I cannot get Visual Voicemail to be configured. A support rep said that the only reason LTE is working i
