LTE+ How to enable!

LTE+ The Easy Way!
I've been pulling out my hair trying to get LTE+ and root at the same time. I was doing something differently two days ago and couldn't figure out what it was. And then BAM! :laugh:
If you follow the BlueFox721 Carrier Switch Guide and go with unlocked firmware, let's say Att or Tmobile, you at a certain point "Echo" in the sales code for that company... like ATT or TMB. I changed mine to TMB for UNLOCKED Tmobile, but TMB is ALSO the code for LOCKED Tmobile. Basically when I would reset for SamFail, (Nearly identical to PwnFail but for Note 8) the system was seeing a US based phone, asking for a TMB setup, so I got LOCKED TMB 4GLTE
All I had to do after rooting to achieve LTE+ was:
Go through the phone setup process
Install Terminal Emulator, run TE, type SU for Super User (You have to grant it Su access, and if the SU command works the $ symbol in TE will become a #)
Then type the following:
echo "XAA" > /efs/imei/mps_code.dat
Then press return!
And then type
Exit (followed by return)
And finally
Exit (you guessed it, return again!)
(The first Exit gets you out of SU, the second one closes Terminal Emulator)
That changes the sales code to US unlocked. Then reboot into recovery, do a factory reset, and when your phone boots it will probably show H for signal. After setup if it isn't LTE or LTE+ just toggle Airplane mode on and off and Voila! You should be now able to get LTE/LTE+ !!!
Hopefully this can save people some headaches and provide faster internet to the masses!
(I had max download speed on speed test 103mbps)
If you need the carrier apps like visual voicemail, Verizon or other carrier app, check PLAY STORE, or try the method below:

The "Carrier Aggregation" has to be enabled in your area by the phone carrier. If it is then I believe it will, but this just enables it on the phone, not in the towers

On my phone I only connect to band 2 on TMB. When I boot as XAA I get 2 and 12, and the LTE gets a Plus. You can use *#0011* to see your bands. It'll show the LTE you are on, and below that the CA line will either say 0 0, needs configuring, or show the 2nd band of your CA.
I never use Wificalling and Google Duo is at least as good as tmobile video calling so U1 firmware is best for me.

How did you do it? I'm always stuck on the screen where it says, "Restart your phone to configure the features supported by your new SIM card. This will reset your phone to its factory default settings, erasing all data, including files and downloaded apps."

Mi A1: WiFi Calling does not work on T-Mobile in US

Just got off a multi-hour chat with T-Mobile tech team in US: they confirmed that they can't make WiFi Calling work on my Xiaomi Mi A1 (Global). Regular calling (Band 4) works fine.
Quote from out chat:
I have reached out to the highest level of Specialized Tech Care, and worked with them on the provisioning issues. With the Xiaomi MI A1 being a non-T-Mobile non US based phone, the option may show as available, but the device itself will not actually operate on, or use the wi-fi calling options. We can absolutely help you get into a device that supports the feature, but there is not a way to activate it on that device.
The provisioning failure is on both sides, we cannot activate the service, nor force an override to update the IMS.
The plan is setup and good to use it, but the systems are giving us an error saying that the feature is unsopported.

Symptoms and details:
Phone is a Global version with Oreo 8.0.0 and the latest security patch (Feb 1, 2018), not rooted, fully stock.
I tried enabling WiFi Calling in the Phone dialer app to no avail (Hamburger menu → Settings → Calling Accounts → T-Mobile → Wi-Fi Calling)
T-Mobile tried re-provisioning the phone. Their system was sending a special sms to enable WiFi Calling. It was understood by the phone, so I was seeing it as a regular text message:
FREE T-MOBILE SUPPORT MSG. Q's? See <REDACTED LINK TO TMOBILE SUPPORT SITE> WQGxYT92fBTCECnvS4QOiu7gzm4NPHiWMYoeXEs5riY=:WFCn|414b7f5b

Debug menu (*#*#INFO#*#* in the dialer) is still showing IMS Service Status → IMS Registration: Not Registered.

It sucks that voLTE doesn't work on T-Mobile US as well. It's what I expected when I got the phone anyways, so I can't complain too much.

yup sucks. regular calls is alright but to make up no VoLTE or wifi calling I just use google duo calls to my friends and it sounds excellent. only downside is I can only use it with people who only have duo installed.

VoLTE works great with this device.
Ps from India

It's so weird that my mobile company supports VoWifi and VoLTE but the phone doesn't seem to understand that. No option to enable and when i force enable it via shortcutMaker it disables itself. I double check that it's enabled by calling the company and they say that if my smartphone supports it, it sould be enabled by now...

Volte works fine here in my country

VoWiFI doesnt work in Greece, too.

VoLTE not working

Hi, I had Poco F1 before with working VoLTE, so I know that my carrier and current Sim card is supporting it. All I had to do on the F1 was typing in that code *#*#86583#*#* and activating the new volte setting.
I tried that with the X3 but it's not working. Whenever I receive/make a phone call my connection will switch from 4G to 3G.
Is there a workaround or is it a hardware limitation? I could imagine because the X3 just has an entry level SOC that the modem has some artificial restrictions to differentiate from the flagship SOC (845/865).

Did you get a volte carrier check disabled message after dialling that?
For me both volte and vowifi are working fine

Yes I got that. Are you telling the phone your real location or do I have to chose India or china? I remember with my Poco F1 I had to chose India to get features like call recording...btw I'm in Australia.

Changing regions
Anyone know if I do a factory reset and change to a different region like Europe will that make the phone operate on different Verizon bands possibly allowing me to get service? Just a thought ?

If you got the VoLTE was disabled message after entering the code, go to SIM settings and there will show the option to activate VoLTE. If not appears, try to enter the code again and check the SIM settings.

I think using different bands it's more about regional ROMs construction (Global, India, Europe etc) than changing region in ROM settings. Alternative, you can flash a different regional ROM using MiFlash and see if it helps with your problem.

After entering that code I get the switch, to turn on volte, but that doesn't change anything.

Can't you see the specific VoLTE symbol near mobile signal in the upper right corner of the screen? If you can't see it, you can try to make a phone call and see if the google dialer shows it's a VoLTE call (or check the dialer history calls if you use Xiaomi dialer....you'll see there if it was a VoLTE call or not).

Same here with my Poco x3 NFC global I am on Vodafone UK my carrier support volte and vofi but I can't enable it , I have no settings . What I found when I flash custom ROMs the volte works , the sound in voice calls is super crisp and I got the icon always there vote on sim and vofi on WiFi . I need an option or a menu or a trick to show that option in stock ROM to enable it .
I remember back in the days when I had OnePlus I had to go in the ingineer menu to tick on a toggle " enable volte" and "enable vofi"
And later on the OnePlus 7t pro I had to install an apk to force that toggle so I can enable it .

On my Mi Mix 2s it shows volte when enabled. This one no. Poco needs to fix this before a number of users get dumped for lack of volte.

Did you try activate it using this codes in Dialer? VoLTE: *#*#86583#*#* and VoWIFI: *#*#869434#*#*. After that go to your SIM settings and you'll get the option to activate VoLTE and VoWiFi.

I have tried those and I left it on enabled both of them . Still not working

If you have an locked bootloader I'm not aware about a method to flash another regional ROM. I had read that many Poco X3 users have problems getting mobile data connection with Verizon (especially in USA).

Hello anyone has managed to operate the volte on both sim cards simultaneously on his POCO X3? thank you

Same here in Italy, no volte, it switch ti 3g. With my previous 8t all was fine

I am using the stock room and used the dial codes got the settings but everytime I tried to make a call it wouldn't work I went to setting all specs and tap internal storage 5 times then choose the sim you are using then you have to turn the top switch off then back on. This is how I got mine working I also have extended my storage by using root explorer and cut everything under sd card and move to storage.

LG velvet 4g volte on Tmobile?

I have LG velvet 4g dual sim LM-G910EMW, is there any way to enable volte for use on t-mobile?

im having the same problem with my carrier (simple mobile). they are saying my LG Velvet 5g is not compatible with their network upgrade to VOLTE. The specs for my model, do indeed show that it is compatible. They keep trying to get me to "upgrade" to a new phone. Whats going on here?

So I followed the below directions from reddit and it worked great and I now have Volte, however phone still drops to 3g when it makes a call any thoughts on how to fix that?
There is a way to force enable VoLTE on the "LG Velvet 4G Dual Sim" specifically your version which is the "LM-G910EMW".
By default the feature is disabled on this model variant for who knows why.
Follow the steps below: 1. Click on the "Phone" app and dial "##4636##" -If done correctly it'll automatically bring you to the "testing" settings menu.
Click on "Phone Information" -you should see a list of VoLTE settings however by default they are disabled and greyed out but don't worry there's a way to reactivate VoLTE. (You Will Come Back to this Menu later)
Go to your file app and create a file named "enable_ue" -thats all you need to do just create the file, nothing more nothing less.
Go back to the "Phone" App and dial "#*462633*#910#" -This code is specific to the variant and will not work on other non LM-G910EMW Phones. Dialing this should bring up the "Hidden LG Menu"
Select Field Test>Universal Enabler>Create New Config -a menu with check boxes for VoLTE options appearing
Select the boxes as follows "VoLTE" "ViLTE" "VoWifi" "ViWifi" And finally hit "Confirm" -a prompt will appear stating "Vo Services Updated"
Immediately restart your phone to allow the settings to kick in
After your phone has restarted go into your Settings>Network & Internet>Mobile Networks -If done correctly the VoLTE option will now be unlocked and available.
Switch on the "VoLTE"
Now to double check that your phone now truly has VoLTE enabled, repeat steps 1-2. If done correctly the menu should now say "VoLTE Provisioned Video Calling Provisioned Wifi Calling Provisioned " -if these 3 are all switched on then you have successfully force enabled VoLTE on your LG Velvet 4G Dual Sim LM-G910EMW, congratulations!

Sorry I'm not so good, can you help me please regarding this:
Go to your file app and create a file named "enable_ue" -thats all you need to do just create the file, nothing more nothing less.
I would like to know how to create this file, as I think I didn't do the job so I'm block when I enter Unviersal Enabler, it say: not supported
Thanks in advance for your help

In the upper right of your file manager there should ne three dots, click on that and it will show new folder, new file, etc.
Some file managers do not have a new file option so you may have to download a different file manager. I used 3c as my file manager.

Hi,
Can you please share the path where we need to add the file name as "enable_ue" and it will be 0 byte file right?

I just added it to the main storage and yes it was 0 byte

Will this work on the 900TM variant? I used 900 instead of 910 to get the hidden menu and it came up but i can't seem to get the volte button to enable in the menus.

If you have one variant of a Qualcomm LG Velvet can you turn on VOLTE by selecting the stock firmware for a different Velvet variant? Basically I wondere if an lmg900tm can be turned into an lmg900um. [NOTE: upon further investigation, the VOLTE feature may depend more on the SIM card and not on the firmware. There is an explanation here from Quora.com:
Is VoLTE activation dependent on the SIM card or just on the device model and the operator?​
The phone has to be VoLTE compatible, that is the hardware itself must be able to handle VoLTE in terms of what it implies: band, frequencies and so on.
Then, the phone has to be provisioned to operate with VoLTE, in simple terms that means that the phone must be enabled or allowed to work with VoLTE, this is done wither by the manufacturer or by the operator. There are phones that even while they are VoLTE capable, the manufacturer of the operator won’t provision them to use VoLTE. One such case are the Google Pixel phones that are perfectly capable of VoLTE. but, if you insert a SIM card of a country where Pixels are not officially sold and supported, then Google has the phone set to disable VoLTE (and 5G as well).
Then, the SIM used in that VoLTE capable phone and VoLTE provisioned phone has to be of the right version. Some operators won’t provide VoLTE service if you don’t have a SIM with a minimum version (and thus SIM firmware and configuration).
Lastly, you have to be physically present on the network that has VoLTE capabilities. You could have all of the above, but, if you are in the middle of a desert or in the middle of the Atlantic Ocean, probably VoLTE is not going to work…and neither 4G or 5G…
Is VoLTE activation dependent on the SIM card or just on the device model and the operator?
Answer: VoLTE activation is controlled by the device depending on the SIM and network operator. Of course the phone has to be VoLTE capable in the first place. Each device has an internal database that uses one or more of the SIM files as key to retrieve various parameters about the operator own...
www.quora.com
There you have it, that is pretty much in simple terms, what is needed to enjoy VoLTE with your smartphone.

Activating VOLTE on unlock V600TM(Tmobile)without rooting or installing whatever

I activated my VOLTE for my unlock TMObile phone V600TM running on the latest android 12 version 30f by just the below commands
enter dial, type *#546368#*600#
Field test
IMS setting
Test
PreferenceOperator put OPEN
Preference country put MY (according to your country example Indonesia would be IND or America with be the US and so on)
Tick the 2 options below
✓ Support Volte on Command
✓ Volte setting enabled
restart ims process
Once done go to the mobile network option and add the below APN(not sure if this APN is universal but it works for me in Malaysia in all the carriers so I guess you can give it a try) don't delete the existing APN
APN: ims
APN name: ims
APN type: ims
after that restart your phone and you will see the VOLTE sign appearing next to the wifi symbol and so on. Make sure your 4G signal is strong enough if not it won't appear.
Also, I notice when I use the 4636 commands to check it still says IMS is not registered and Volte is not provision but I can use Volte maybe this is the bypass as I tested the call and so on already just make sure your Sim card supports or is Volte activated as well.
Also the Volte setting wont appear in Mobile network but it will work with the VOLTE icon appearing

My TMObile V600TM phone is network locked.
How to unlock it? if yes could you please point me out?
thanks

Lg phones g8x, g8, v60, velvet Volte enable for all carriers, unlisted countries also
I will try to keep this post as small as possible. This will enable Volte for Phone ranging from Lg g8x, g8 and V60 without root or modifying the system files. Many have posted ways to get it, Iam only trying to help out the small bits missing...
forum.xda-developers.com
thanks to the OP for this thread, really pushing for these amazing devices to live on, you can follow my first steps to get the IMS option to open up.

Tried it on V600TM30C in Greece (GR) Cosmote and worked! Thank you! I have tried other ways (rooting,etc) but none worked so far.
I have also tried it on V600EA10 but I couldn't enter IMS settings menu and the johndaniel tutorial didn't seem to work, so I restored my back up to V600TM30C. I still need to find a way to have 5G.

anyone tried Lg v60 L-51a ???
