4G Data but no voLTE calls defaults 3g

Hello all,
Recently purchased this phone.
As stated in the title I get 4g but when making or receiving a call default to 3g. Immediately back to 4g as soon as call over.
I disabled region check and Enhanced 4G LTE Mode toggle appeared in Mobile Network Settings. I enabled and restarted.
Also went into phone info using *#*#4636#*#* and all flags for voLTE are on there as well.
Carrier: Consumer Cellular (T mobile sim)
Bands 2 and 4
Does anyone know how to resolve ?

"#"#86583#*#*

Have you enabled volte with your carrier?

Maybe this can help you:
Download and install 4G Only Network Mode from Google Play Store.
Modify advanced network convigoration by opening the secret settings:
Click on Open Secret Settings
Under Set Preffered Network Type, choose LTE ONLY
This will automatically force your phone to exclusively connect to the 4G LTE only network.

I called them, they did something on their end so now calls start in 3g but go the 'H" after a few seconds.
Probably still not volte but an improvement.
My understanding is that volte calls have an "HD" for this phone

volte carrier check needs to be "disabled" btw
try switching to airplane mode and back. also make sure you have your sim in sim1!
what country/carrier are you on?

Yes, you're right. When volte is enabled you should see an HD icon next to your signal strength icon. Just like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After your carrier enables volte you should reboot if you haven't already. Volte is used only with 4G, so after the reboot you should get the HD icon when you're connected on 4G. To test it out (or if you are still on 3G/H) do the following:
Press *#*#86583#*#* on dialer until carrier check is disabled. If it says enabled, just type it in again.
Then press *#*#4636#*#* on dialer to start the hidden menu. Go to the first tab, I believe it's called phone information, and scroll down where its says preferred network type. Note down the default value (it should restore on reboot and flight mode, but just in case) and select LTE (or 4G if it's called that) only. You will lose signal for a moment, and then you should be back running in 4G. Obviously, you need to be on a location with good 4G coverage.
Then, just make a call. If it gets through without dropping the data connection (4G symbol stays on), you're on volte. Go back to *#*#4636#*#* to restore your preferred network type, and enjoy

I tried everything posted so far but no luck.
I have a nexus 5x on with an identical sim on the same network/towers that shows me lte over the bars.
This phone only shows me 4G ..... is the phone capable of displaying lte ?
When selecting preferred network type lte only. It will drop the call.

LTE is 4G. Each phone uses different symbols, but it's the same. The fact that it drops the call probably means that volte is not enabled... weird. Have you contacted your carrier about it?

https://forum.xda-developers.com/mi-a2/how-to/guide-volte-t-mobile-yes-actually-t3869677
I just figured it out. Just follow the guide.

Thanks for the post Daha3ker ..... I will see if anyone else tries it before giving it a go.
I am quite sure at this point its a network issue as it is also happening on my Nexus 5x (LTE then H during call)

Confirmed it is a network issue. They are sending me ATT sims to try.
The tech support wasn't the brightest bulb, she kept trying to convince me I need to be on wifi to place an LTE call.
After some passive aggressive attempts to convince me she finally told me T-mobile does not support volte with them.

VoLTE depends of the carrier, it has to be enabled on his network equipments.
Some carriers enable it per phone line (they have to enable it for your line)
Moreover, some carriers restrict VoLTE for specific devices. Here in France, Orange enable VoLTE only for Apple and Samsung devices...

What if you just use a Samsung or Apple device to enable it?
Here in Greece, Cosmote also enables VoLTE only for specific devices, Samsung, Apple and Huawei. The Mi A2 isn't one of them. But I managed to... side-enable it. I just inserted my sim card in a Huawei device and sent the text to enable it. They enabled it in my sim, and of course it still works after I moved the sim back to the A2

Orange say that it is available and automatically enabled on Apple devices, and on Samsung devices which were purchased in Orange stores. So I think there is something special in phone rom.

Problem resolved. Was a carrier issue.
Required an ATT sim and add a new Access Point
* Note if using Consumer Cellular you will need the ATT sim for Volte.
Tmobile does not support Volte on CC as relayed by tech.
Thanks to all who posted.

I have MetroPCS Sim in miA2 does it support VOLTE ?

Thanks bro best solution

Is my 5G actually 5G?

Am on Vodafone Ireland. Phone purchased direct from carrier.
VF Ireland released this in early November, I think. It wasn't up until the December Pixel update that 5G actually started working and, until this point, Google had 5G support for the network down as pending on their support page (since updated). So far so useless from Vodafone.

The thing is, I'm not actually sure they've (being Vodafone) correctly enabled 5G for the device with Google. I understand that speeds can be spotty but a speed test when on (what the Pixel reports as) 5G are identical to those performed on LTE.
So, I have the Pixel displaying 5G in the status bar but NR frequency in *#*#3646#*#* is showing UNKNOWN (not sure if expected), Data Network Type is LTE (again, potentially expected?) and speeds are identical to 4G (I know there's a chance this is just the cell I'm connecting to, but little opportunity to test otherwise at the moment).
I'm not rooted; is there an app or website that will give me a cast-iron, low-level look at what type of connection is actually being made? Or any other thoughts?
Many thanks!

When you're on 5G go to settings -> about phone -> sim status, mobile data network type should be NR NSA
Which is sort of a hybrid between 4G and 5G where you (supposedly) get 5G speeds but not all the other 5G features.
5G SA isn't really rolled out many places yet and I don't think the pixels support it if it was

Yeah, it is NR NSA. Certain speed/performance test apps are identifying the connection as LTE, though, which is why I was looking for something that I knew could be relied upon to give an unequivocal read (if such a thing can be done).
I can't help but be suspicious that VF have messed this up somehow and whilst the phone is identifying a 5G signal, it's not actually what's being used.

This may or may not help.
If you go to settings, network & internet, advanced, adaptive connectivity and turn it off then the phone wont use 4G if it thinks that is all you need when a 5G signal is present.

Have had that turned off since update, thank you, though

I note that if I manaully try to connect to a network, I am shown as connected to a 4G one, where the network "3" have a distinct 5G one. Anyone on Vodafone IE (whether a Pixel 5 or otherwise) able to confirm if they see a distinct 5G network for Vodafone, if they try the same?

NR Status: NOT_RESTRICTED = not connected to a 5G cell, but not restricted from doing so either. It will say "CONNECTED" when actually connected.
NR Frequency may not work properly. On an old patch it erroneously reported "HIGH" for T-Mobile USA which means it thought I was on 5G in the 3-6GHz range which is not possible for my carrier. On a new patch it now just says Unknown always.
"5G" shows in the status bar because many carriers want their phones to show the icon when you are connected to a tower that "supports" 5G NSA connections - which effectively means there could be a 5G cell somewhere in the vicinity.
I use CellMapper as a quick way to look at the NR Status (AKA 5G State). If you're connected to a 5G cell it will also list a NR NSA item near the top, or say LTE-A+NR NSA.

That's very informative, thank you!
So, if I'm seeing the attached with CellMapper, I'm on a 4G cell but there is a separate 5G cell for my network available?
Should note as well that I am now seeing CONNECTED for NR Status but am still not getting anything above 4G region speeds.

I'm actually kind of confused by the screenshot. My Pixel 4a 5G has never shown a "NR" item, and you're missing the all the 5G info on the LTE line. However, I know the 4a 5G is not compatible with my carriers 5G Standalone yet. I wonder if you are on Standalone? I would suggest opening CellMapper then when you see the info like in this screenshot, go to Settings>Send Debug Info and use the email option. The devs might be able to figure out what's going on. Send them a screenshot of the main app window, too.
Re: speeds...it depends. I can sometimes get faster and more consistent speeds when I disable 5G. But that's because one of the main 5G bands for me is only 15*15mhz wide, and there are some modem limitations when aggregating in a 5G band with LTE (NSA mode). For me, I have to find the mid-band 5G cells (N41) that have 60mhz of bandwidth to see a bigger difference. And then there's mmWave which is the ultra fast 5G but very limited range.

Thanks once again. Going to throw it up on the CellMapper Reddit first, I think. See if they can interpret it for me.

normal behavior for 5g. right now it's basically LTE speeds with a layer of instability on top.
mmWave is never going to happen. we just have to wait until 5g (sub-6) is stable and speeds improve.
personally, I've disabled 5g on my device. not worth it.

Hmmmm.....maybe where you live. Here in Canada I get about 60/70mbps download speeds on LTE. When I get a 5g connection the speeds can go up to over 200mbps

@xunholyx That is insane speed. You know where I can cross the border?

I am on Verizon prepaid and live in a rural area. I bought upgraded 5G Sim from Verizon for the Pixel 5. I have the low speed 5G coverage that Verizon calls nationwide. It's really a glorified 4g lte that is often slower than lte. Phone shows 5g at the signal bar and setting show NR . BUT speed test app and opensignal app shows that I am actually getting lte signal and speed when testing. I have found out that in my yard standing away from power lines I get 4g lte speed and signal but if the phone is held higher I connect to the tower with 5g protocol and speed test reflects it with double to triple bandwidth.result page of speed test and opensignal show 5g connection.

Can CellMapper show me all 5G bands supported by my phone? Or it is showing only actual connections to the nearest cell?

VoLTE, WiFi calling with the upcoming 3G shutdown

Visiting the US and trying to find more information on this upcoming 3G shutdown.
From what I have learned from calling/chatting with T-mobile, AT&T, Sprint, Mint Mobile, Boost Mobile, Straight Talk and Consumer Cellular (** all this info is not guaranteed completely accurate as not all cell tech support people actually know everything - not a knock - how could they know everything about 1000 different handsets just saying)
Following anything you see below is certainly without warranty. I am not responsible for bricking your phone or turning it into a coffee maker.
Okay so enough disclaimer. Here is what I think I have learned:
For reference my phone is a V40 ThinQ LM-V405UA. It was manufactured for Sprint - bought it unlocked and refurbished.
AT&T has already shutdown 3G calling and all voice calls are now on VoLTE... but maybe not in all areas??
T-Mobile and it's MVNO's still have 3G operating and plan to shut it down in July.. ish...
Mint Mobile and Boost shows my IMEI to be compatible.
Consumer Cellular show my IMEI to NOT be compatible.
The AT&T store told me in person that I would NOT be able to enable VoLTE on my phone with the network since it was made for Sprint
AT&T Chat - escalated to Technical Support - confirmed that there was no way to enable VoLTE and that it would not function on their network.
Chatted with T-Mobile, Sprint and LG - they could not tell me any service codes or techniques to enable VoLTE. Each did kindly tell me I should check with LG, T-Mobile, Sprint...
*#*#4636#*#* brings up the Testing Menu
Under Phone Info you can switch on "VoLTE Provisioned"... (YES!! - right? ...not sure this does anything)
Below that is a toggle for "Wifi Calling Provisioned" . Mine is grey'd out in the off position
You can set the preferred network type - and mine is set currently to LTE/CDMA/UMTS auto (PRL) - not sure what that means but...
You can enter the "HiddenMenu" by dialing *#546368#*405#
I clicked all around and found only one thing
Click SVC Menu
Scroll down to VoWiFi (Ahaaa!! right??)
Click on Wi-Fi Calling Toggle and change the value to 1 - on
I rebooted and... no change.
I currently have a Mint Mobile sim (T-Mobile towers) and it currently works. Gleaning from what I read somewhere - if you truly have VoLTE activated and configure correctly you should be able to have data to load a web page DURING a call (with WiFi switched off). Mine fails to load during a call.
If you have VoWifi configured and activated correctly you should be able to make a phone call having Cell data switched off and attached to WiFi. Mine can not make a call.
My wife's Xioami phone does all of this and even has little VoLTE symbols at the top of the screen.
Hopefully all of this information helps someone else - but even better yet - hopefully someone can tell me if I will still have cell service in July when T-Mobile is shutting down their 3G service. Are there other tests I should be doing?
Also for fun - pulled my LG-V20 from the drawer and messing with it. It shows that WiFi Calling is WORKING... Battery is bloated but I think I had a successful test with it.
Anyway - that is where I am at. All tips, tricks and ANSWERS are appreciated.

I don't know if flashing it to the AT&T or open market version rom would do the trick but probably would. Note, since it's refurbished you sure it wasn't already reflashed to the open market version rom? If so it should work!
AT&T might have gotten confused by your description...
AT&T whitelisted phones:
{
"lightbox_close": "Close",

}

My understanding, and it could be outdated, but maybe not, but at&t (supposedly) checks imei, and if it's not one of their phones, there's nothing you can do to make it work. From your description, it *sounds* like they are still doing this.
For VoWifi to work, with my mint mobile sim at least, you have to go to your mint account and turn on VoWifi ability. So not only does the phone need to be capable, the sim needs to be provisioned for it. Many people overlook this part.
There are numerous indicators of VoLTE working. Many times when you bring up the dialer there's a little HD symbol on the talk button. Other times it will give you a little LTE symbol on the status bar when making a call (and it doesn't change to 3G during call), etc.
The VoLTE situation is where 'what rom are u running?' becomes very important. The lte bands that the rom is capable of need to coincide with the carrier you want to use. The 'Open US' roms have the most bands available, and is usually a great choice for T-MO (and mvno of t-mo). Even has band 71 (which is only used by t-mo).
Lastly, for those that may not be aware, after market roms, like lineage, aren't capable of VoLTE (or VoWifi), for most LG phones. that's because LG (and Sammy) both use a 'proprietary' IMS stack, which means those Vo technologies only work on their phones with their roms.

AT&T doesn't care about who's phone it was as long it's imei isn't blacklisted.
What is important is the hardware which can't be changed or the firmware which can be changed.
My guess is the issue is the former. The carrier variant phones can have slightly different hardware configurations.

Thanks gang for the notes.
I'm running stock rom. I'm not rooted nor bootloader unlocked. I'm a bit resistant as this is my daily driver phone plus there doesn't seem to be clear confirmation that cross flashing something will really result in better performance. Add to that I won't be able to reinstall whatsapp nor my banking app etc - since my home country sim and phone number (Colombia) won't receive a confirmation text until I return there in October. Tough situation.
But I've got more test results
@AsItLies - thanks for that - I was able to enable wifi calling in the Mint app. I also called consumer cellular to confirm that my sim had volte and wifi calling enabled on their end. This was all done before testing below.
I found some exciting new settings inside the hidden menu.
Dialing *#546368#*405# choosing: Field test / GPRI VoLTE+VoWifi / IMS / Slot 0
VoLTE was enabled (possibly from steps done above in my first poat?) But I was also able to enable VoWifi ViWifi and ViLTE. I enabled them all.
After making that change I dialed the Testing menu - *#*#4636#*#* - Wifi calling Provisioned and Video calling Provisioned are still greyed out in the off position. VoLTE Provisioned is still on.
Testing - I can make a call using a Consumer cellular (At&t mvno) sim. I can not get cell data during the call though- same results as with my Mint mobile (T-mobile) sim.
I was told that At&t has already shut down all 3G calling so my phone MUST be using VoLTE if the call worked?
I have read unconfirmed reports that not all 3G calling has been shut down since some of the cell towers have not been upgraded yet... so could be I just get lucky.
My wife's phone can make calls with either sim AND get cell data during the call. (so does that prove that the nearest tower must already be upgraded?)
My wife's phone has nice symbols and setting sliders for wifi calling and volte calling - all enabled
I tried running tests with airplane mode on and wifi enabled - but it wont make a call that way on my phone or the wife's phone.
So basically it seems like nothing has changed. I'm still not convinced that I will have a working phone in July ish... Any more tips on testing and verifying that are appreciated.

It's likely running on 4G VoLTE.
This is how my Note 10+ is configured, no changes were needed.

@blackhawk - My screen looks very similar.
My preferred network type is set to - GSM/WCDMA/LTE (PRL).
I am not sure if that was the default or if I fiddled with that... I am going to dink around with that and see if changing that solves my problem. But
But I did some more testing. I was away from the house at the grocery store. I dialed my phone with Mint Mobile sim in and my 4G symbol changed to 3G and the call went through. I did have data during that time - but painfully slow.
Grabbed the wife's Xiamoi phone with her Consume Cellular (AT&T Mvno sim). Dialed and the 4G symbol stayed on and she had data of a reasonable speed.
So - I am believing... not proof... that my phone is still dropping to 3G to make calls and is skating away on the still operating 3G system of T-Mobile. Evidence that I might be without calling in July.
I should test the reverse - and pop the sim out of the wife's phone and try my phone with an AT&T sim and see if I had no calling service.... but she doesn't really like when I pop open her phone in the grocery store. She puts up with a lot - but I didn't have any "geek credits" in the bank so I will have to plan for that later...
Anyway - that is the latest.

Set it to that setting I'm using.
Clear Sim toolkit data.
Network reset and a reset on AT&T's side too.
The APN profile should ATT Nextgenphone I believe.

@blackhawk - thanks. I have an AT&T sim to fiddle with now (Straight talk this time).
AT&T only gives me 1 bar here in my house.
It seems no matter when I chose as my Preferred network type - I get
Out of service area / Mobile network is unavailable
SIM not provisioned for voice
But I don't have a SIM toolbox on this phone. Can I get that installed without root? Can you point me in that direction. Because maybe that is what I need to do next is clear that - especially since I keep popping in random sim cards.
Thanks again

Oh - skip that - brain dead. I got the sim toolkit cleared...
On with the testing!

Did some testing again with my Mint SIM - i get 4 bars here...
Did you know that you can have the dialer, Testing menu and Sim Toolkit settings page open/split screen or background screens at the same time? Well that saves some time... By the way the HiddenMenu won't stay open as a background page... Just so you know.
So here is my testing sequence: Wifi switched off. Dial the local automated weather number and then switching to the Testing menu to watch the reported "Voice Network Type" . Record results. Enable Airplane mode. Got to Sim Toolbox and clear data. Disable Airplane mode and try a new "Voice Network Type".
Basically all of the settings for "Set preferred network type:" that include UMTS or GSM will work. But the Voice type drops to GSM or UMTS. Data drops to UMTS , HSPAP or sometimes EDGE. 5 seconds after the call ends the Phone Info page reports "Voice Network Type" and "Data Network Type" as LTE.
Any settings like LTE Only or something that doesn't include UMTS in it - the calls just fail. Actually - if the "GSM Service" inside Testing Menu/Phone Info reported "Emergency Calls Only" under "GSM Service" - then you can bet the call failed. Despite really wanting to do complete testing - I did not dial 911 to see if it would work. Just seemed wrong to potentially interrupt a real emergency - even in nowhere USA.
I found some more interesting settings inside HiddenMenu / IMS Setting / GPRI VoLTE / Slot - 0 / Roaming
Inside there are VoLTE and VoWifi - I enabled all the roaming options inside each.
But - alas no change to my tests so far.
I tested the Wife's phone on Straight talk and the Mint sim = VoLTE symbol
So that is one AT&T and one T-Mobile MVNO
Preferred Network Type: LTE/TD-SCDMA/UMTS
Worked great. Testing page showed that the voice call stayed on LTE. I enabled Wifi and tried getting it to transfer to a VoWifi call but - even with 1 bar it wouldn't go. If you have 0 bars it won't initiate a call. Probably a security thing as they don't know if you are a real subscriber??
Anyway - I think that proves?? that my phone is still not doing any VoLTE nor VoWifi calling and will likely fail or have extreme problems as the 3G network fades away.

On my N10+ the hidden menu stays open until I close it. Makes things easier.
Get the carrier advanced tech support to troubleshoot it if possible. You probably know more about than me at this point.
I can highly recommend a Note 10+ N975U1, they run great on Android 9 or 10; Android 11 and especially 12 not so much so. I have two, just bought another new one about 5 months ago.
It's a better flagship Samsung than the ones Samsung released after it in my opinion.
New factory sealed ones are available still for $800 and used ones in "excellent" condition for half of that. In a good case they will easily last 3+ years with only battery replacements. The one in my hand is 2.5 yo and looks/runs like new with zero display degradation. It's heavily used. Current OS load will be 2 yo in June, still fast and stable with minimal maintenance. Supports up to 1tb expandable storage.
Both the N975U (AT&T variant) and the N975U1 (unlocked) run seamlessly on AT&T. There's a 5G variant but it will likely eat more battery.
It's display is one of the best, maybe the best in any smartphone even today It's gorgeous with an exceptional color rendering index and white point. Being 60hz means less power consumption and better color rendering/calibration, great for vids.
It's just a snappy fast fun work horse of a phone that has excellent build quality.
Lately Samsung and Google Android have been subpar... dropping balls.

That is a smoking fast phone! I may have to give this phone up and move on. But that has issues of it's own as I will still have to keep this phone around because there are a bunch of apps I won't be able to install on a new phone because I can't get my sms confirmation until I get back to South America. But not a whole lot of other options.
Thanks again,

You're welcome.
It's a true pain migrating to a new device. I hope you get that one successfully running on VoLTE.
If you like that large of a display, it's form factor is still the best. Better display to bevel ratio too. Lighter and thinner the S22U with better SOT.
Watch this vid where the N10+ literally smokes the S22U after both rams get loaded up with apps. wtf? I'll take the dinosaur Note...

Question Origin OS and enabling 5G outside of China

Hello guys,
So I've imported a Vivo X Fold from HK and I was wondering how do I enable the 5G bands? I've seen this thread for Samsung, is there perhaps a similar method or something else to do for Vivo?
(Of course, I checked, my carrier is using bands supported by the Vivo X Fold)
Thanks!

I've just imported the Vivo X Note from HK and it has the identical Origin OS Ocean firmware and the same radio hardware and frequency bands as the Vivo X Fold. I just plugged in the Sim Card I had been using in my Samsung Galaxy Note 20 Ultra, and voila, I had 5G service. I had the same question as you, because sitting in my study at home my phone displayed 4G+ at the top, but the other day I put it in the car cradle and as I drove down the street it switched to 5G. I then realized that my house is not within transmitting distance of the local 5G tower, but many other areas of the city I live in are. As a brand new technology 5G coverage is not as broad as 4G.

Not sure if this helps you but I ordered mine from China. I live in the Netherlands and 5G worked "out of the box".

There is actually a setting on the phone that is off by default. Settings/Mobile Networks/Sim has a toggle for 5G. I toggled it on and had a 5G connection (Canada) right away. The options that appear in that Sim submenu, however, are activated by inserting your carrier's Sim card. If your carrier supports the Vivo X Note or Vivo X Fold for 5G, VoLTE, and WiFi Calling, you will see three toggles there - one for each. In my case I only have the toggle for 5G, no VoLTE or WiFi Calling settings because my carrier will only provision those services for phones that it sells. If you go to that submenu and don't see the toggle to turn 5G on, then you may need to get a new Sim card from your carrier. Some carriers require the use of a new 5G Sim card, others allow 5G with an ordinary LTE Sim card.

I am using the X Fold on T-Mobile USA, while the 5G icon is showing when I go into System management≥ Status Info≥ SIM 1 Status it's only displaying my phone as connected to LTE and shows as having no signal for NR. From running speed test I can confirm I'm getting the same speeds as my Xiaomi Mi 11 Ultra which only runs on LTE. I have T-Mobiles 5G home internet where I get 400+ download speeds so 5g coverage isn't an issue in my area.

T-Mobile's "5G Home Internet" uses a Wi-Fi Gateway (combination modem and router) that connects to T-Mobile nationwide XR (extended range) 5G towers which broadcast on 5G frequency n71. The Vivo X Fold can't connect to these towers. It can connect on 5G frequencies n1, n2, n3, n5, n7, n8, n12, n20, n28, n38, n40, n41, n66, n77, n78, and n79, but not n71. T-Mobile has put up a few Ultra Capacity (UC) 5G towers in big cities and if you are range of one of these your Vivo X Fold will connect on 5G n41 and display "5G UC" when it connects. These new towers also broadcast on 5G n258, n260, and n261, but the Vivo X Fold won't connect on those frequencies. So long story short - your T-Mobile Wi-Fi Gateway will connect to 5G n71, but your Vivo X Fold won't, and unless you are within range of one of the new 5G UC towers your calls will connect on 4G.

I am aware, I am in NYC my TMo gateway is connected to N41. The tower is across the street from me. Here what I see on my phone.

Odd that your phone is displaying the 5G symbol (as well as VoLTE 'HD') when your Sim Status signal strength shows 0 for NR (5G), but is showing a strong 4G signal. I wonder what triggers the 5G symbol when you clearly aren't receiving a 5G signal. Have you used a signal diagnosis app like OpenSignal to see what is broadcasting in your neighborhood?

Everything except mmWave. If you have the phone and T-Mobile service are you running into the same issues?
I'm leaning towards following this tutorial as this is a Chinese phone and 5G might not be configured to work in the US.
Modify OnePlus 7 Pro 5G, 8 and 8 Pro, 9 and 9 Pro NR/LTE-A band combos - MT-TECH.FI
On this instruction we will modify OnePlus 7 Pro 5G, 8 and 8 Pro band combo profiles with Qualcomm software. OnePlus has limited 5G access and 4G+/LTE+ Carrier Aggregation combinations and this instruction help you to unlock. However this instruction doesn’t unlock hardware defined combinations...

I think you have hit the nail on the head. Countries and telecom carriers had the choice of deploying 5G NSA (not stand alone) or 5G SA (stand alone) technology. 5G NSA provides a 5G signal that piggyback's on a 4G signal and actually relies on an already established 4G infrastructure (towers, servers, switches, etc.). For a 5G phone to work on a 5G NSA network, the phone must have both the radio bands for the 5G frequency, and for the underlying 4G frequency that is necessary for the 5G NSA to work. Most American carriers opted for mmwav 5G NSA technology. On T-Mobile, therefore, your Vivo X Note or Vivo X Fold are 5G SA and 5G NSA compatible, but because T-Mobile uses 5G NSA the phone must not only be capable of connecting on T-Mobile's 5G frequency, but also on the 4G frequency that its 5G frequency piggybacks off. That 4G frequency for T-Mobile is LTE 71, which the Vivo X series doesn't have. I'm in Nova Scotia where my carrier (Rogers) built a 5G SA (stand alone) network, so as long as I can connect on one of its three 5G frequencies (I can connect on two) then I don't have to worry about the phone also connecting on an underlying 4G frequency. But unlike T-Mobile, my carrier won't provision VoLTE for my Vivo X Note, so all my voice calls drop to 3G. If T-Mobile followed my carriers policy you wouldn't be able to place any phone calls because you have shut down your 3G towers. So I have 5G for data (downloads, streaming, etc.) but 3G for voice calls, and you have 4G for data and voice, but no 5G.

Are you able to manually turn VoLTE on with the code *#*#86583#*#*? There is also an option to turn on VoNR in developer settings.

Thank you for sharing this. I used the dialer code and it gave me the option to enable VoNR (although it didn't give an option for VoLTE). I enabled VoNR but while my phone shows I'm receiving 5G, when I place a voice call it still drops to 3G or H. I phoned my carrier, and they told me they have added the IMEI of my Vivo X Note to the line and have provisioned VoLTE, but I don't believe them. When I called them the other day they told me if I wanted VoLTE I would have to purchase the device from them. After enabling VoNR with the dialer code I can go into developer settings and there I see that it is toggled on, but the Settings/Mobile Networks/Sim 1 submenu still just shows the toggles for "enable 5G" and "enable data roaming", both of which are turned on. I just don't have the "enable VoLTE" option there. If I was rooted I would force the option to appear by editing my build prop, but I don't think anyone has figured out how to root the X Note or X Fold yet. Someone is working on root for the X70pro and they have successfully flashed FunTouch on the CN Origin OS Ocean model, but trying their experimental method on my new Vivo X Note is a bit to adventuresome for me.

I'm sure you've probably tried this already, is VoLTE greyed out in the *#*#4636#*#* service menu?

I just had an interesting argument with a service tech for my carrier just now. Each time I call I get a different tech and a different answer, but his guy gave me the stock "if you didn't buy the phone from us those features won't work" line. I told him I know people who have non carrier purchased phones and VoLTE and WiFi Calling works on their phones. He said: "that's because they are using a model we sell ourselves". Knowing that none of the Canadian carriers sell Huawei devices I aske him if that would apply to a non-carrier Huawei purchased in Hong Kong. He said "of course that wouldn't work". I then asked him to look up the account for my wife's line, which he did. I asked him what information his screen was telling him about her line. He said "I see her IMEI was registered on May 17th". I told him that was correct because on that date I swapped SIM cards between our phones and when I put her SIM back into her phone it would have registered again on their network. He went on to say: "it says in bold letters here 'non-carrier device' and VoLTE enabled NO, WiFi enabled NO.". Her phone is a Huawei Mate 20 X which I bought at Trinity Mobile in Hong Kong three years ago. VoLTE and WiFi Calling both work great on her phone. I can toggle off VoLTE on her phone and her 4G signal drops to 3G when placing a voice call, or I can toggle VoLTE on and place a voice call and it stays on 4G and displays the HD Call symbol as well. Weird science!

I tried to check if volte is greyed out but *#*#4646#*#* doesnt work with the phone. how can i go to that menu?

I have tmobile and live in illinois and my 5g and volte is working. Can confirm if you need pictures.

Same but i had to force root to get VoLTE working

Maybe it is Operator dependent as here in the UK (on Three.UK) I have 5G everywhere where other phones have it and also I have HD Calls icon and VoLTE enabled (have not done anything specific for those to work). Pretty soon Three.UK will be shutting down their entire 3G network so there will be only 4G and 5G...

Hi Guys, Just sharing my experience with you . I'm in Australia with Vodaphone. % g works as well as volte, haven't done anything special. I've travelled to the US this week, and 4g is ok, as well as Volte.

Question 5G not enabled by default

Hi there,
I apologize in advance if the question has already been answered. I searched but found nothing.
And I apologize for my English, I'm French Canadian.
I bought a OnePlus 10 Pro 12gb/256gb, model NE2213 last week.
Everything works fine except for 5G. I only have 4G (LTE) by default but with the 5G settings app I can select the NR option to enable 5G. Everything works fine and I can use 5G without any problems.
When I restart my cell, I again come across the 2G/3G/4G option only, no 5G.
The option seems to be there and functional but it does not seem to be activated by default.
Is there a solution for this?
Thanks a lot !!

Besides your APN there's not a huge amount you can do.
Is your phone an actual NE2213 or has it been converted?
If it's the latter then that could explain things..

Thanks for your answer!
This is an original NE2213 model purchased from a Canadian website. It was 30% cheaper than the North American model and I read on the internet that the bands were compatible with 5G.
It's not the end of the world because 5G is not really deployed here in Canada but I don't understand why I can activate it via the 5G settings app but when the device restarts it seems to be desactivate.

No, I live in Canada and I'm on the Bell Mobility network which uses the n66 and n78 bands for 5G.
This website sells different cell phone models less available in Canada (OnePlus, Xiaomi, etc.) but sells Chinese or international versions.
Like I say I can live with it, 4G is as fast as 5G here for now, but I was wondering if there is a solution to enable 5G directly on boot.
Fun fact, when I set up the cell for the first time, it was showing 5G in the top right but when I was done with my setup and turned off the wi-fi it was rendering 4G and i can't choose 5G in the network options.

Just out of curiosity, what's your expected speeds on 5G and what are you getting on 4G..I don't use 5G on purpose. I simply don't need it as 4G gives my 250Mb +
Anyone who needs more then that needs a PC

I did a live test...
5G: 69/3 Mbps (d/u)
4G: 56/5 Mbps (d/u)
I'm at home and wifi is off.
Basicallyt, not a big difference, I'm going out today and redo a test to see if the speed is really different.

Do another test outside of my home...
4g : 61/24 Mbps
5g : 141/44 Mbps.
Big difference this time!

Can you force it with the engineering code?
