My phone: Samsung Unlocked variant running on AT&T
Using a dialer code I've found an app "Testing" that shows options to enable the VoLTE, Video Calling, WiFi Calling & I'm able to pick network type (GSM, UTMS, LTE, ect.) Some options work and some don't. Maybe somebody smarter than me can look into this and possibly enable 4G LTE on AT&T, as well as the other features?
Code: *#*#4636#*#*
Awesome..thanks
have you tried calling at&t and asked about adding your imei for them to enable those on your device.
Thats what i have read online that tech support from at&t can make this service works with unlocked note 8.
Im still waiting for my Unlocked Note 8 and wondering how to enable Volte (HD voice). i dont use wifi calling that much though.

Changing networks does change my connection from 3G to HSPAP to no connection, depending on the option. The VoLTE, Video Calling & WiFi calling are temporarily enabled but then turn back off. Likely provisioning issue but that's all i can tell.

I have and they advised there's no issue. They can't seem to figure it out but I've spent several hours and multiple calls trying to determine if it's an issue or the way things will be.
The only interesting thing they advised of that there's no device description on my account. (Typically it'll at least say Samsung Note8 got example but they see nothing) IMEI and SIM were updated upon activation.
unless something has changed recently, you have to have an ATT phone for all of these features to work. i can only get HDVoice (VoLTE) working on my Note Fan Edition and my wife's S8+, both of which are Exynos devices. I had to call ATT and (a) have them assign the IMEI of an ATT phone (S7 Edge and S7 Edge +) to each account and (b) by flashing an ATT CSC (from a Snapdragon ATT S8+) to the Note Fan Edition and the S8+. The ATT CSC's enable options for Wifi calling and video calling, but these features aren't working on either phone.
Hows your data speed? Do you get 4G LTE speed data?
coz you said your connection is going from 3G to HSPA+

I average just under 5 Mb/s (Megabits, not megabytes which is about .5 MB/s) on H+ Latest test was 4.6 Mb/s
I do not get LTE, but am in a heavy LTE area (Phoenix, AZ) and get solid consistent LTE on my Note 5

WOW thats totally sucks! Im now worried about my preorder.
I might have to cancel my order from samsung and get an At&t brand note 8. I hope this is only a temporary problem with unlocked note users.
Thanks for all the info! good luck on getting all those at&t services.

I have an unlocked note 8 with an AT&T sim. I get great LTE speeds. In the city I get 100 plus Mbs at home or in the country I still get about 20 with only 2 bars of LTE i am only missing VoLTE and wifi calling
I'm hoping it's a setting issue on their end or something. I'm continuing to find a knowledgeable AT&T rep with some info. Good to know the unlocked version gets good LTE speeds. I'll get a new SIM and continue to look for a resolution. Worst case I'll flash radios as that looks like it's a developing option.
I gave up trying to jump through hoops to get WiFi calling and VoLTE and just bought the dang AT&T version when I preordered... If someone could come up with an easy way to get it all with an unlocked version...I'd be tempted to jump on it but until then, I'm stuck with the AT&T load.

That I wanted to be able to use wifi calling and it doesn't work. The went through and made sure all features were enabled.
I have spoken with multiple AT&T reps and after speaking with someone ('ha-seen' is how it sounded) who said that they were with the Level 3 team I was told that video and wifi calling are all proprietary to AT&T and that you have to have a branded phone with their build and that the unlocked version would not have access to this.

I got the same answer. I am calling and complaining to Samsung, I mean I pay to use the AT&T network and the features and the phone is capable of both volte and wifi calling there should be an easy way to fix this.
Just picked up the Note 8 U1 for use on AT&T, switching from a S8+ that was AT&T unlocked. I don't use WiFi calling, advanced messaging was cool but not having it won't hurt, I think. VOLTE is the big question, I know it's voice over LTE but how will that effect me talking and surfing the web at the same time?

So I was bored and wanted to play around and try to get this to work. So far I have been successful to get data text and mms working on 3G. Now I have noticed that when I boot the phone that it connects to LTE with a strong signal then it reconnects back to 3G its almost like its possible but something it blocking it. Has anyone had success getting further?
UPDATE: I have gotten FULL LTE on Verizon working. Currently trying to figure out a way to allow CDMA as well for calls
Ya good luck I had same issue as you . Talk text 3g working good. Or LTE only working .Never could figure out how to get them both going
Yea I know after hours of messing around lol and two sim cards wasn't satisfying enough I like the phone enough to jump off big red to try T-Mobile. I honestly like this phone better then my Pixel XL
I ditched my Verizon unlimited data plan for cricket unlimited and have no regrets. Best choice I ever made

It won't work it's one or the other. You are wasting your time
The city I live In has Verizon's xlte network and if you upgrade to advanced Calling then voice calls and messages all use 4g LTE data instead of CDMA, so I would only need LTE data to work, I was able to get the 1+1 to get Verizon's signal but after 5 mins they noticed and intentionally blocked me off their Network a message popped up on the 1+1 saying I had been blocked

Just curious how you have "LTE" activated on the phone. I turned on "only LTE", but I get absolutely nothing. I am only interested in LTE on t he phone, I do not need to make voice calls of SMS
Force LTE provisioning
I know that people had the same issue on the ZTE axon 7 but we're able to force LTE provisioning by going into the dialer and dialing *#*#4636#*#*. This brings up a hidden test menu and under phone information there is a switch for LTE provisioning. It takes a few tries but eventually sticks on the axon. Can someone try this on the one plus phones to see if it works?
I know this has been rehashed many times, but I thought I'd share a my experiences of how to make the 3T usable on Verizon. Main reason I have the 3T is dual SIM and OEM bootloader unlock. Fantastic device. Switched from Verizon to AT&T just for the phone. The problem is my work uses Verizon. I refuse to carry two phones. So what I've done to solve this is bought the GravityBox app, which has a feature that allows, (among many things!) you to add a custom quick setting shortcut for Network Mode. It lets you decide which SIM the setting applies to, as well as any network modes to cycle through when pressing the shortcut. I of course pick the Verizon SIM. And only select two network modes: 1 CDMA only and 2 LTE only. CDMA only allows calls,text and 2G to work perfectly. When a sending or receiving a MMS on Verizon SIM, or needing to use Verizon LTE, I toggle to Verizon LTE only. This does kick AT&T offline for some reason, but beings that I rarely need to use Verizon data, it's not that big of deal.
So sorry if this was common knowledge but I haven't seen anything on this yet so I thought I'd share. I decided to try setting up AT&T's number sync between my new mate 10 pro and my LG Sport and it worked. What makes that amazing is this is the first non att branded phone I have ever been able to set up directly between the phone and a att smartwatch that didn't require me using a att branded smartphone in the middle. You can't find the ability to do it through the my att app or website but if you initiate through the watch, it will open the browser on your phone and then give you a number sync code, once you log in through the browser, you put in the code and then accept terms and it will successfully link. This phone also seems to work well with the LG Sport. Battery life is waaay better then when it's paired to my Att Note 8.
FYI, Att number sync allows multiple devices to receive a phone call or text message from the main line they are tied to. That way every thing is seen from one number. One of the requirements is that the phone must be Att branded.
So that tells me between this and VoLTE working on att with this phone, this phone was all but ready for att network and only thing missing was the att branding on the phone before att backed out.
Sorry if long l, just wanted to share to maybe help other att users.
Have you been able to get/verify that VoLTE is working on your mate 10 Pro? If yes, how did you verify it works? I have a Dual Sim 10 Pro rebranded to the US 10 Pro (did at Best Buy) with the Enhanced Voice and VoLTE options enabled. Thanks.

I didn't use the default apn that sets up when I had my att sim inserted. I used the settings from att's support page: https://www.att.com/esupport/article.html#!/wireless/KM1218306
If I remember, there were a few subtle differences. Honestly, I didn't notice if VoLTE was working before the new apn settings but I see that it works for sure with the new apn settings. My status doesn't change from LTE whether on call and/or browsing.

No problem. I was thinking, you said you rebranded to us but I wonder if by a slim chance there is some hardware difference that is dectected? Like maybe a certain band att uses. I haven't looked at the differenceces in bands between models.

Cellular bands are the same as US version; when not in a call I connect to LTE+. I can achieve cellular download speeds of 98 Mbps. Main difference between US version and mine is my phone is dual SIM Mate 10 Pro. The second SIM connects to 4G when I make a call. If I use only 1 SIM, connection drops to HSPA+. I see an option to enable VoLTE on the second SIM, but it's disabled. Have you to find a way to enable it. I appreciate your feedback, thanks again.

i have the same setting/option and it's also enabled; see below. will contact at&t again tomorrow.
So I spent an extensive amount of time about this whole VoLTE situation with this phone with both At&t and ASUS. My question is how do you know if you are actually utilizing the VoLTE connection?
I am able to make clear voice calls while browsing the internet or downloading an application. My speeds vary anywhere between 60 and 100 Mbps with no connectivity issues. The phone has no indicator of LTE connection but is constantly 4g++. Asus and at&t both stated that is the LTE connection. So I went into the phone settings via the image in this and it shows the VoLTE setting not toggled.
So the next question is, what indicator is there that this connection is NOT VoLTE other than this toggle? The speeds appear faster than Hspa+ but nobody I spoke to had the technological knowledge to be able to explain this. Also what speeds down and up is everyone else receiving?
From what I have read, this phone doesnt support VoLTE. And what worries me is that all the carriers are transitioning to VoLTE starting in 2020. Some are saying phone calls will no longer be possible on this phone. Which confuses me as it just released.
You can tell by making a voice call and seeing if the phone stays on 4G++ or drops to 2G/3G. I am 99% sure we will not get VoLTE on this phone. TMobile rep suggested tweeting TMobile on Twitter as the marketing team there might help, but I just don't care anymore. I'll stick with my pixel 2 xl for now.
Is ANOTHER thread on this necessary? Wtf? No volte. Not now, not ever. Get your money back. Asus are idiots for releasing this phone in us with no volte. 2020, no phone calls. Enjoy!

I know VoLTE is 100% possible on this phone, however not in the USA. It has something to do with the USA companies and At&t told me VoLTE is definitely a possibility as well as WiFi calling in the future but that has to be certified by the US companies. This phone supposedly works with WiFi calling as well as VoLTE in the European market as they don't have the same issues with the companies controlling the way it operates. I am moving to Norway on the 23rd but honestly the connection has been fantastic and I do like the phone quite a bit. During my phone calls I remained at 4g+ or ++ while surfing the web or watching Netflix with no issues during the call or the film itself.
I have messed around with it to see if there was anything that seemed off about it but so far it has worked just as well as My note 10+. Also the phone is operating on 4g so saying that it can't be used is silly. The 4g band will be around for quite some time while some companies like Verizon are removing 3g as it operates on the cdma versus gsm. At&t will continue 3g operations until 2022 and 4g will take years to completely phase out from 5g and by then another phone will replace the ROG 2.
I will however annotate how this phone operates on the European networks once I arrive. As per my previous post I can obtain 40mbps up to 100mbps which is definitely 4g speeds. 3g can not obtain those types of speeds. The bands available are key to the operating network for sure though. I think at&t seems to offer the best fit here in the USA.

I am currently using this phone with AT&T. So should I be good for calls through 2020 and 2021? Reason I ask is because I literally just got it a week ago, and then read this news about the whole VoLTE thing and was just devastated thinking I have to now find a way to sell it and find a new phone.
Also, since I got the phone, I am only ever on H+ for the signal. I thought it was LTE capable? I came over from Verizon, so the H+ was something new to me. I know I am in a LTE area. Do I need to do something to activate it?

Was this a ported number? When I went from Verizon to at&t there was an issue when I ported the same number back to at&t. They were able to get it resolved by calling Verizon having them refresh the port and then re initiating the LTE from their end. And that was with my Samsung. I did speak to at&t again today about the LTE and they may have to make sure your Sim is "LTE" and also making sure they unlock it on their end. Supposedly the LTE and volte have to be activated from them. Also ensure you have the appropriate APN setting as sometimes with unlocked phones those setting do not carry over.
And the phone should be working fine until a minimum of 2022 even with 3g or H

I did bring the number over from Verizon. I may have to go in to AT&T to resolve that from what you're saying then.
Dealing with the APN setting, I am good with tech, but this part has me a tad confused. What should I be looking for on the phone? I see under APN, it says AT&T is selected. There are other options like tracfone, but I assume its fine then if it has AT&T selected?

That's interesting, but I would recommend going to at&t and confirming that LTE is good to go on your phone. They can also verify nothing is stuck in the system and your appropriate APN settings
Would like to know if these features are supported for the major US carriers. That's the only thing holding me back from pre-ordering.

I know U.S. T-Mobile supported the XZ3 for VoLTE, which was the FIRST Sony unlocked phone it did that for. Your best bet to find out is prob to go check out other like 2019 or 2020 unlocked phones that people have VERIFIED to offer both on AT&T as well. But if that's an issue, then you may wanna consider T-Mobile then. I noticed on the XZ3 that in Call Settings there no longer was the option to turn VoLTE on or off, but during calls it REMAINED in 4G LTE (vs. just 4G), thereby proving VoLTE was in fact enabled.
The US Xperia 1 supported voLTE on T-Mobile, but not WiFi calling. So I'm assuming the mark II would at least do voLTE on T-Mobile. Not sure about the other carriers, but I feel like it would have to since carriers like Verizon are starting to not allowing non voLTE devices to be activated. And the mark II is supposed to work on Verizon.

How is this a solution? Switching carriers lol
I want to preorder, but really need WiFi calling. Going to wait until regular users start to receive theirs. Right now with Xfinity Mobile we are paying about $30 per month for 5 lines. The service is as good as when we were Verizon postpaid. Not willing to switch just for this phone.

So my Xperia 1 ii arrived today, I'm finishing-up set-up. This is the US model, which I'm using with ATT. The deep dive *#*#7378423#*#* on the software info page states: "Current modem config: VoLTE-ATT "
But have yet to find any configuration for VoLTE or Wi-Fi calling. I'll try a call with one of the other lines in my family, who have ATT branded newish phones, to see if it "sounds" like an HD Voice call (there's not notification bar indicator of HD call, right?).
Update: Tried the other *#*#4636#*#* and the options under Phone Info are all grayed out (sigh)

You have to call ATT to whitelist your new IMEI for VoLTE provisioning. Then you need to make sure a new sim that supports VoLTE. This is what they told me but I'm missing the new sim, going to get one tomorrow
Thank you.,I'll give that a try. My SIM is the supposedly latest, about 2 years old, i. e. "A compatible SIM or eSIM card will display 25, 26, 27, or 28 in the ninth and tenth digits spots." Is there a newer SIM for ATT?
So had the following chat with ATT tech support:
"... Calista : To confirm, was the device purchased through AT&T?
Me : No, this is an unlocked phone, US model of Sony Xperia 1 ii
Calista : Thanks for the confirmation.
Calista : I have successfully activated VoLTE on the new device.
Calista : I have also checked and see that Wi-FIi calling can only be provisioned only on the device that are purchased through AT&T. However, AT&T will soon activate WiFi calling on the device that are not purchased through AT&T as well. You will be notified about this. "
However after power-cycling my phone and reprovisioning via Testing/Phone Information and on that page the steps of Refresh to get the SMSC number then tap Trigger Carrier Provisioning"--nothing, not VoLTE live switch. Remains gray. Still, interesting comment by tech support about upcoming Wi-Fi calling on BYOE.
Anyone know about VoLTE on Verizon yet? Just ordered my phone today and hoping that it will work.

Those tech support chats are useless! Took me 4 calls/chat to get to one knowledgeable one who said they have to file a level 3 tech support ticket and as she was doing it she said our internal memo said this cannot be done for non-AT&T branded phones so I'm sorry
Why not just use Google Voice for wifi calling? I use Google Voice for just about everything now as it's a nice alternative to giving up my number to random businesses.
Is it possible, to install the VoLTE/VoWifi carrier settings by an app (as .apk)?
My problem is that Sony didn't include these settings for Swiss carriers. So I am thinking about, how to add these settings without breaking the firmware.

VoLTE is required to continue to use AT&T after they sunset 3G and 4G (without VoLTE). Speaking of Google, they've confirmed to me that this phone (US version) works fine on their Google Fi, supporting VoLTE, which is interesting in that Google Fi is an MVNO via Sprint, T-Mobile, and U.S. Cellular.
So if I give ATT an IMEI for a Nokia Lumia 830 or Microsoft Lumia 640XL (both on AT&T's "good" list) to associate with my SIM in my Xperia, will my Xperia be provisioned by AT&T with VoLTE & Wi-Fi calling?
I have consistently used unlocked devices on the AT&T network OR used U1 firmware on a U-original based carrier device. In the past I have had to flash additional things to the U1 firmware to get VoLTE or WiFi Calling on AT&T. To do that I would flash the U1 firmware and then flash the U Home CSC
BUT -- good news (this is the first Samsung device to do this for me) the ATT calling features (VoLTE and WiFi Calling) work right out of the box for my Unlocked Ultra !!
Wow.! Great to hear. I was going to get the ATT S21 Ultra in 512GB but they were sold out at Samsung, so I got the unlocked version. I am glad to know I won't have to jump through a bunch of hoops to get those features. Now on to get a working Gcam and debloat things I don't need

My 5g works. When I got the Note last year my 5g didn't work. The problem was that ATT had to put me on a 5g plan to actual provision it. Were you for sure on a 5g plan?
It works on my U1 S21 Ultra for sure

you have the factory unlocked s21 ultra right from Samsung.com? I`m on the highest cost prepaid plan for 75.00 one that's the only prepaid plan that offers 5g service, so they have started service ticket to get it fixed, so we`ll see, I just switched from tmobile to ATT yesterday.

yeah I had forgotten about the APN, I use to change this before on other phones I had with ATT, my is Nextgenphone APN, I tired the enhanced one and it will not allow me to add it, so it must be something on the end of ATT network, I still haven't heard about my open service ticket to get this fixed, I`ll post up my APN in a while.

So here's what I know from prior experience. You are on the wrong plan. As so as ATT puts you on the right plan your APN will immediately automatically change and 5g will work if it's available. Check out a thread in the Note 20 forum. It happened to me and a couple others as 5g was rolling out esp to us looking term ATT users
yeah I`m on the correct plan, I think they never finished setting my service up correctly, I had just called ATT again, then he said we would

well I called ATT like 10 mins ago to find out why I`m still not getting 5G, I told him I try to enter the ATT enhancedphone APN and it wouldn`t save in my phone, so goes well lets go to the APN settings, so I went to the APN settings, low behold the the APN had automatically changed to the ATT enhancedphone APN, so as soon I saw that, I turned off my wifi and boom I had 5G, I know I had the unlimited plus prepaid plan that`s the only plan that allows 5g access, I`m thinking my plan wasn`t fully set up correctly on ATT end, but its fixed now Thanks for the info.
Do you guys actually have VoLTE working on the S21 Ultra unlocked? I don't have any options for VoLTE on mine.
WiFi calling showed up for me when I got the phone but not VoLTE. I went to the AT&T store and got a new SIM card because the WiFi calling wouldn't actually operate. This fixed WiFi calling but still no dice on the VoLTE. I also switched to a 5G plan which works as well, but that didn't resolve VoLTE either.

I agree that I didn't see the volte setting but I'm assuming since all calls will be digital in the future the setting well be superfluous
But anyway here is a call with internet usage in the background and a internet check without call. The speed and LTE indication remains the same demonstrating volte is working

I had the exact same experience. They had to change my plan to a 5g one, and suddenly I had everything 5g.

I don't have a volte setting, but volte works. Considering there's no reason for me to ever turn it off, it doesn't bother me that the option isn't there.
