What is the best way to try to get working Wi-Fi Calling and VoLte on this model phone? Just ordered it yesterday so I don't have it yet
Thanks
I am not a developer but experienced user.
There is MUCH confusion about VOLTE .
To get VOLTE in the past on 99% of phones you needed 2 Things .
1] A VOLTE capable phone .
2] Network SOFTWARE on that phone to enable VOLTE ( and often WIFI calling ). This means you only get VOLTE on Tmobile , for example with a Tmobile BRANDED [ or Metro OCS phone ] with the preinstalled software from the Manufacturer for that specific NETWORK.
Android was supposedly going to ADD this into their system but I don't think it's possible technically or legally.
A friend as recently as a week ago on SPRINT had an S9 with a VOLTE On/OFF setting and when he engaged VOLTE is affected call quality negatively - I heard it.
This is one of the reasons Sprint is merging with TMO , IMO.
I have heard rumors of 'generic ' or AT&T Iphones having VOLTE on Metro PCS/Tmobile for example but real VOLTE stays on LTE always and you never lose Internet due to a call - simultaneous STABLE voice and data is the benefit - not some little trick on /off thing.
If the F/DS is an Exynos you may have issues however someone pointed out in another thread that the Exynos should work with T-Mo WiFi calling.
I am using the firmware for the 965U1, it is generic software for US Based Snapdragon phones. When I flashed and put my SIM in, it detected T-Mobile and set up WiFi calling automagically. The VoLTE also works with no adjustments or settings.
So I am thinking at a minimum you should be able to get WiFi calling. Hopefully.

Can you link the other thread? I plan on buying Samsung Galaxy S9 Plus (SM-G965F/DS) for use with T-Mobile US
How was your experience with stock?
After noticing no one on the internet has a fix for this and after countless failed attempts the answer is simple it is the country code and area code causing the issue. I was also able to fix my wife's mi note 9 pro the same way make sure you have roaming for area codes and remove any country codes from your contacts.
To test, dial a number local to you that is not in your contacts. Make sure VOLTE is turned on and only dial the 7 main digits of the number (no country code exe. +1 and no area code exe. (202) only exe.555-5555) the call should now work.
I believe as long as call roaming is on you should be able to use area codes and for out of state you will probably have to turn off VOLTE for now until Xiaomi realizes American dialing is different from Europon and they mass fix this in all those phones. Soon all the carriers will be VOLTE only and if they do not fix this they will be losing a lot of customers
Hope this helped you guys

Thanks! I turned on data roaming and now VoLte and VoWifi is working perfect on my X3 on T-Mobile here in the states. Good work.

Never mind. It had nothing to do with data roaming. But you were right all you have to do is call a 7 digit number and VoLte will work. Also wifi calling is not working. I jumped the gun.

Roaming fixed my wife's and mine phones to use the area codes and check your settings for wifi calling mine works perfectly...
My phone has been HD with WiFi calling ever since I discovered this no issues at all.
T-mobile says No VOLTE, no service soon to come if your phone does not have VOLTE it won't work there other phone carriers follow as well like At&t
If your T-Mobile phone doesn't have VoLTE, you could get kicked off the network soon
Metro by T-Mobile will also be affected, along with MVNOs like Google Fi, Mint, and Ting (Update: T-Mobile statement)

I live in USA, i removed the 1+ from each contact, and works perfectly. I tried calling myself from one of my contacts phone, and i got the call through, but i can't call my voice mail. I tried turning on roaming always, but didn't work. But i'm still worried some calls might never come through. I'm on xiaomi.eu 12.0.7
So I finally got voLTE working here in the states. We just need to figure out how to remove country code when it comes to voice calling. The phone works wonderfully with Straight talk. I wonder if purchasing an international plan would fix the incoming call issue.
I have At&t and just got the Oppo Find N, chinese version. When i got to make a phone call, it pauses and sometimes doesnt seem to even connect before the call goes through. Data and texts seem to work fine with no hesitation. Anyone else having this problem or any advice? Thanks!
I had the same thin happen while in the office at home is working well.. not sure will test again tomorrow.. are you still having the issue ?
Sorry lads, i was on the same boat as you just a few days ago. My Find N also stopped making and receiving phone calls. Turns out AT&T shut down its 3G services hence you're unable to make phone calls. You'll need to switch to Tmobile if you want to continue using the phone. Tmobile is retiring 3G in July but I believe it handles phones differently than AT&T so we'll still be able to use it after July.
Not sure if that is the case I am on ATT and my Oppo N is on 4G able to make calls…
and might have spoken to soon.. unable to make calls any more.. The weird part is that SMS and 4G internet works..

It is pretty much the case. If youre able to make phone calls currently, it means ATT hasn't shut down the 3G towers in your area. They have plans to complete shutdown by Feb

Right..... You didn't speak too soon. The towers in your area were just shut down. You'll have to switch to Tmobile now.
Since folks here are talking about T-mobile, I have a question.
Does 5G work with it on T-mobile (I'm in the US)?
I saw that it supports n41 which is one of the band supported by T-mobile. But just wanna double-check.

I'm on T-Mobile, and have not had working 5G.
That doesn't mean it doesn't work somewhere... But not here in LA.

I guess 4G LTE speed wasn't too bad?
I've been on both and honestly my 5G UC indicator shows up but the speed difference is not perceivable.
Suggest trying to manually change the band preference using a utility such as '5G LTE' by Rudra Green on the play store. This allows lots of different LTE and 5g options to be selected. The only problem is that the setting is lost after the phone is restarted. I have been using this to enable 5g in the UK.
(US ATT and T-Mobile)
I have this phone, but only by way of ATT telling me my non-VoLTE 4G LTE phone would not work after ATT shuts down 3G.
I move over to T-mobile recently. All works ok. I then activate VoLTE on the Mi. All works ok.
But I had to call a T-mobile rep regarding my iPhone, in that conversation I asked if VoLTE was even needed, and he tells me no, that T-mobile will still do voice data w/o VoLTE enabled.
So, VoLTE is a feature of LTE and implemented on 4G/5G, and really has nothing to do with 3G being shut down.
There's so many sites stating you "need" VoLTE to keep making voice calls after 3G is gone. This is not true.
"As 3G is switched off, you need VoLTE or HD Voice support to make calls on 4G networks."

As I understand it you need 3G for voice.
You may be able to use internet service but without VoLTE, no phone service.
If the device is not white listed it likely will not be able to have phone service as your link states.
I have straight talk with AT&T sim, I was using my Black Shark 3 pro which has volte and all of a sudden Friday at midnight, no data or phone service. At that time my bs3pro has been having heating issues, so i moved everything over to my redmagic 6 which has volte. I noticed my sim was locked in apn, totally different apn info than my bs3pro, so i called support, since everytime I tried to make call it blocked calls and sent me to support. The CS person did something on their end, had me restart phone, then service was back to normal and been fine since.
If your service provider only provides 4G infrastructure like mine... then you need VoLTE otherwise no phone calls. They are new and never had any 3G and below infrastructure. I tried making calls .... it doesn't.
My service provider annoyingly doesn't provision volte for my volte capable handphone (this makes my eyes swivel) but does provide an app to support phone calls without volte.. but it chews up battery
@roger_rex
But T-mobile (US) runs 4G and 5G, but # of towers with 5G not as plentiful as 4G. I connect 4G LTE most of the time, voice & data works just fine. T-mobile rep told me it will work w/ or w/o VoLTE enabled on phone. The APN used is the "fast" APN one.
A 5G connection does not negate any benefits from using VoLTE.
Was on phone again today with a T-mobile "tech team supervisor" for a service issue (they accidentally turned off one of my SIM cards). I then asked about VoLTE, he tells me it's no longer needed on T-mobile 4G or 5G LTE, but using VoLTE will still work. He seemed to suggest VoLTE not needed at all on 5G because the speed of the wireless can carry both voice and data fast enough. He also hinted their 4G can do the same.
If you have a fast pipe then you really don't need a side channel for the voice.
But duly noted, everything technical that I have read about on VoLTE, using that feature gives better voice call on any LTE that supports VoLTE. The supervisor also mentioned that "VoLTE" will basically go away at some point.
Pretty sure on 4G LTE you need either VoLTE capability or a 3G connection for voice calls.
Redirect Notice
4G VoLTE will likely be here for a long time as 5G is distance/obstacle limited, the former is very hard to overcome due to the wavelength's physical properties.
@blackhawk
I am not disputing how online info says it's required, I am just copying what T-mobile has told me.
T-mobile store rep tells me VoLTE is not really needed, then their online support supervisor tells me the same thing. So it is for sure confusing.
Call a T-mobile support # and ask.
Why would a 3G/4G-LTE phone have an option to turn off VoLTE?

I never paid much attention to this and still have questions but it's back burnered for when I run across it. From what I'm reading the T-mobile reps sound like they don't understand it either.
Even if they don't understand it... the only thing that matters immediately is if it will work. Hopefully that intel is correct!
Really until AT&T implements the change I won't be 100% sure. However pretty sure I'm ok as the devices don't use the 3G band and in hidden user settings VoLTE is toggled on. The only indication other than the 4G that VoLTE is active.
Probably HD too, but no indicator or setting other than very good call quality.
To make matters even more confusing AT&T changed the format and models listed drastically 2 weeks ago from their December whitelist. So small wonder reps might be confused too. Makes you wonder if it was deliberately self serving, an oversight or ongoing system modifications?
So, I have not been paying close enough attention to cellular these days. The cell companies have amassed large sets of licensed bands, probably near 200+ bands between 2G/3G/4G LTE and 5G NR.
Interestingly enough, 5G is not LTE at all. I suspect operators call their crud "5G LTE" to signify they support 5G-NSA or 5G-NR (or both), and, the older 4G LTE.
Some airlines are worried about two cell C bands (n77 and n79) that back up onto aircraft radio altimeter that run 4200-4400Mhz.
VoLTE has a long history, but it seems 5G-NR does not even use VoLTE (because VoLTE is a LTE feature, and 5G is not LTE). Can a 4G/5G phone still use VoLTE? Sure, if the firmware is implemented to use it. Likely will use it if the device connects 4G LTE, but perhaps will not when connected to 5G-NR. It's not clear to me if a device will use both 4G LTE and 5G-NR at the same time, but I suspect not. I mean, you could technically connect a device on 5G-NR for data, and then use VoLTE on 4G LTE for facilitating voice calls.

My understanding on this is that voice was using some 3G or below service. My provider was purely 4G and above - so unless my phone was provisioned by the cell company - no voice calls. I tried & it didn't work. I changed to an older device that they did support via VoLTE and calls worked. I can download an App from the cell company that allows my pixel 2XL to work on their system.
I can only guess T-mobile has 3G and below network infrastructure still. My provider is brand new and never built any 3G stuff and have no intention of rolling out obsolete stuff. VoLTE is annoying in that the provider gets to pick and choose which cellphones they allow (to use a standard protocol)
This may not be 100% - I've been kind of forced into a crash course on this myself over the last few days

Hi all. First of all I DO NOT PROVIDE ANY KIND OF SUPPORT. YOU ALONE RESPONSIBLE FOR ANY POSSIBLE ISSUES. I wrote this post during my vacation. I know it could be quite handy, but unfortunately/thankfully my primary sources of money are...
forum.xda-developers.com
Pixel 2's all have ability for VoLTE.
A cell operator should not be blocking any phone from using VoLTE.
When you call your provider what do they tell you when you tell them your Pixel 2 has VoLTE for 4GLTE but your Pixel won't make calls on their network?
I can tell you for sure, the operators play games with their support of hardware.
My iphone XS was connecting to ATT with a "5G" icon from time to time, so why does T-mobile say 5G is a "no"? I moved the XS to T-mobile and the phone won't ever connect to 5G, and the APN settings appear to be blocked.
Tutorials | T-Mobile Support
Update: I find many sites that say the Xr and Xs do not support 5G, so now I scratch my head, my Xs would sometimes show "5G" icon for cell wireless, when it was on ATT network. Apparently AT&T supports Xs and 5G, hence the Xs does have 5G capable radio.

I think they go at least partially by number of a given model in use. My guess is it's not a painless procedure for them to configure their system for a given model.
AT&T first listed their Note 10+ variant but not the unlocked variant, a month later it was added as well. It may be a work in progress... it seems sort of helter skelter, oh my gawd get it done, whatever it takes... kind of deal
You know they are catching Berlin air raid volume flack
Before buying Mi 11 Lite 5G I went into a T-mobile store (not an affiliate). I asked if the Mi 11 Lite 5G will work on T-mobile and the rep told me all phones work on T-mobile as long as they are not locked to another carrier, and, the T-mobile freq bands ("channels") are covered by the phone.
Unless LTE or 5G-NR/5G-NSA is improperly implemented on the device, then I don't see why all phones should not work. They should all work.
Think about hotspot. The carrier can control is the device can use that service, or at least can with some devices, but why bother, who cares how the data on the data plan gets chewed up. Go over the plan and get charged. Thus far I have not seen unlimited hotspot data, T-mobile only allows 40G on their Magenta Max plan.
Good thing is, Mi 11 Lite 5G phone (model M2101K9G) works a-ok on T-Mobile USA. I did have to manually set the APN to the "fast" one, and had to use dial code for VoLTE, 4GLTE and 5G works.
Straight talk now keeps shutting off my service every 3 days, last night again, so 3 times now. Call and back working. But seems like they only care about giving me some crappy free phone and seems like they outsource. The redmagic 6 is not on AT&T list, if any more issues I will switch to T Mobile, T Mobile recognized my phone by imei and said it is fully compatible. I Noticed on my Redmagic 6, sim 1 is only 14 digits but sim 2 is 15, so I moved sim card, might be issue, but doubt it.
@Rotwiler I see you posted about the IMEI digit thing in another post/forum. *#06# should reveal a 15 digit IMEI. If it shows only 14 then the phone is hiding one digit. Put sim card in sim slot that has the 15 digit IMEI.
What does *#*#4636#*#* get you? Do some gooling around for activating VoLTE on RedMagic 6
Phone lists for carriers are mostly for support reasons. If the phone has all the cell bands the operator uses, then it should be good to go. If the phone only has some of the cell bands used, then the phone may work ok in one area, but not good in another, all depends on how the operator runs the bands in different areas. The cell operator does not want the support headache for a phone that only has partial bands, "hey ATT, my phone not working in Timbuck-too", etc.
The RM6 appears to have most of the ATT 4GLTE bands (all the major ones), so it should work a-ok on ATT (US). 5G should also work. It appears the RM6 had a firmware update about 26d ago. Make sure the firmware is updated to latest.

I am using AT&T through Straight Talk. I did move sim card to slot 2 to see if issue was due to sim one showing only 14 digits. Phone is fully updated. Odd thing is I cannot change the APN since this new Volte, there is red check mark and everything is grayed out. I have always been able to modify APN until now. My sim card is really old, used to be full size and over the years cut it down for new phones, is probably 8+ years old, had it since Android phones came out, but has always worked great.

APN settings are grayed out when the phone is locked to carrier. Can you at least see what the APN settings are? If the phone is owned outright by you then tell the Straight Talk folks you want the phone unlocked.
As for old sim card, then just go get a new one from the store for a few $, and then move your number to the new sim card via online.
Phone is Redmagic 6 global version, never was locked.
