LG G4 IMS problems - solved

All,
I, like others have had a living nightmare with repeated 'Unfortunately LG IMS has stopped working' which keeps popping up every few seconds. I noticed it happened after wifi lost connection, and the network switched to mobile data. Most annoying as I was having to press it up to 20 times when in car as I was driving along!!! I was so desperate I even asked LG for help, and at one point considered reading the manual
I tried everything - even factory reset and nothing worked.
Mine is a LG 818N dual sim model imported into UK, (running on Sim1 - three and Sim2 o2) so not sure if this is factor.
I think I have found a solution at last.
Go into the hidden menu - on phone dialler, dial 277634#*#
When in the menu, select Field test > Modem settings > VoLTE on/off > Subscriber and untick IMS to disable it. I restarted the phone, and the annoying messages were gone.
I believe IMS can be turned off without any major loss of functionality - if anyone knows the effect, please post here for others. So far I can't see any difference other than I can use my phone again

HEY, I was searching for an answer these days too, and just 10 mins ago I flashed back to ver.10b hoping that it will help...... anyway thanks for your tip there.

VoLTE is an improvement over GSM and WCDMA voice service and is the 'wave of the future'. As such LG and the associated operators who use LTE and VoWLAN, voice over the WiFi, Wireless Access Network should be fixing this sooner rather than latter.
This is mostly LG's problem but the buck has to stop with your service provider because that is who you pay for delivering service that is not crapola. The network service operator must arrange their network to use VoLTE and switch from voice over WiFi to VoLTE. Both of these are IP based, using the same basic set of protocols as a common web browser. The advantage of that is voice can be embeded into and between applications including integration into social networking, picture posting and exchange, video conferencing apps, etc. VoLTE is much more agile and should be made much more seamless, ie. without drops, and poor quality. VoLTE is able to pack more calls on the network at higher fidelity than all other voice. '3D'+ multiplexed voice and software voice cancellation, for example, can be done, potentially using multiple devices watching an event, for example. This can be be the direction of evolution or it can stick with the old glitchy voice networks of the past.

LG IMS has to do with the WiFi-Calling feature.
There's a safer way to fix this problem. In the hidden menu, rather than disabling VoLTE, scroll down a bit (in the same menu "VoLTE on/off") to "IP Version." Change this setting from "IPV6V4" to "IPV4V6." If the problem persists, change it to "IPV4," and the problem should vanish.
A LOT of networks don't support IPv6 yet.

airplane mode
the "Unfortunately LG IMS has stopped working" sometimes keeps popping up before you can set up the hidden menu options.
by setting your phone to [ airplane mode ] -- this will help you get through the hidden menu settings.

In india it must be ON for VoLTE services . and i never dealt with the this kind of ims stopped problem

How to enable VoLTE on Pixel?

Hi guys.
Let me elaborate my question.
1. I am totally aware that VoLTE on Android at the moment generally requires the handset to be from the carrier, or from the same region as the carrier for it to have the correct VoLTE (and VoWIFI) settings.
2. I am also totally aware that since Android 6.0, there actually has been a provision to allow carriers to send carrier settings to the user. I also know that this isnt being widely used.
After my ownership of my Pixel XL, I moved to a HTC U11, which I have flashed a custom ROM. This custom ROM managed to have the carrier settings for VoLTE for my carrier baked in.
I am keen on getting a Pixel XL2, so Im keen to see what the Pixel community is doing to enable VoLTE on networks that arent stocking the Pixel or Pixel XL.
Here in Australia, both generations of the pixel seem like they will be Telstra exclusives. and I am not inclined to go on their network!
Thanks for any assistance!

I use it with T-Mobile, only Verizon stocks it in the States. Volte works fine for me. Nothing i needed to do other than to setup the phone with the Sim card in the device.

Same here, got it with my T-Mobile SIM card.

This worked for me. Go to dialer and dial
*#*#4636#*#*
Phone Information
Turn on VoLTE
Turn on Video Calling
Turn on Wi-Fi Calling
Exit

I'm on Oreo 8.1 on my P2 XL, looks like it's already enabled. I'm on AT&T.

Change carrier. AFAIK you'll never get enhanced LTE services using a non-AT&T branded phone on their network. Once I switched my pixel xl to T-Mobile things like that and wifi calling worked fine.

My condolences to your Pixel XL 2. I was in a Verizon store the other day just to check out PXL2. The blue tint when turning the phone horizontally - horrific. Also, barely faster than my Pixel XL, even if you care for that kind of thing (speed.)

Same problem in Argentina, Pixel is NOT SOLD here so.... out of luck, but I tried this (already knew of the menu) and all my options are blacked out -can't enable any of them-, advice?????
Thanks.

If you can get root on your phone, flash magisk and there is a module in there to install that can enable VoLte and Wifi calling, worked for me on AT&T.

the module only changes the settings to allow for toggling but does not provide needed ims libraries.

I had to toggle VoLTE off then on, restart. It's working for me now

"Turn on Video Calling"
Option is disabled, couldn't turn on

Depends if you're on Verizon or straight talk or what. I'm on straight talk and they don't offer VOLTE even though they use Verizon towers.

Using *#*#4636#*#*, the VoLTE provisioned option is greyd out. Anyone has a solution for this?

It means your operator is not offering VoLTE, or, as in my case, Pixel XL is not approved by the operator. I have VoLTE on my SIM enabled and working with operator approved devices but network rejects Pixel as not compatible one.

Operator offers VoLTE and it doesn't filter IMEI like in some cases. Other not approved devices (e.g xiaomi, oneplus) managed to enable volte via shortcuts. I am asking for a similar workaround. --thanks

Of you're on Straight Talk you're SOL. They don't offer it even if you're using a Verizon SIM

If you had geryed provisioning options you need to use magisks voenabler. a did it right now on december pie update. Now I have all enabled. Just waiting for operator to enable volte for my number. I wonder it will active.

Hi, my carrier does support VoLTE but the Pixel is not on its whitelist.
When dialing *#*#4636#*#* and going into phone info, the switches for "VoLTE Provisioned" is off and greyed out, but at the top of this screen I see "Voice Network Type: LTE". Does that mean I am getting VoLTE? I cannot see any other sign or symbol when calling. (I know some devices have a VoLTE symbol either in the status bar or during a call)

Wifi calling

So is it possible to enable wifi calling and/or VoLte on stock 8.1 rooted or any firmware of the pixel without being on Verizon? I am on AT&T so just wondering if there is a mod or something I can do to enable it.

Magisk has a module that can do that; VoEnabler .... this module will enable access to the features in the pixel, in Dialer, settings, etc. * but that doesn't mean you can actually use them;
First, check that your carrier/service actually supports the feature .... You can check with a secret code though; in Dialer;
*#*#4636#*#*
Then navigate to "Phone Information"... from there scroll down;
you should see the stuff for VOLTE, Wifi Calling, Video Calling, etc. If it's enabled then you may be good to go..
but if your carrier doesn't support it - enabling it via VoEnabler will do nothing to change that.
Also, I don't know about the US, but in Canada - some carriers (under some plans) do charge extra for this stuff.

It is all carrier dependant, i got my XL from Verizon and I'm on TMO and wifi calling and volte is working but I don't think att supports the pixels for volte and wifi calling

Sort of this. Basically AT&T will not support VoLTE or WiFi calling on any unbranded unlocked devices brought onto their network. Never worked on my T-Mobile Note 4 nor my Google purchased Pixel XL. I was a long time subscriber to their service but once my dependency on MMS messaging increased I had no choice but to switch to another carrier. I wound up on Verizon after a brief time with T-Mobile. Both support full functionality of these devices.

Before installing magisk I dialed that number and they were all greyed out, I installed magisk installed the module and now VoLte and Wifi calling are both enabled in that menu and in the settings menu. I tested wifi calling and it worked. So maybe just need the module installed and it will work. That's what worked for me.

Cool. glad to hear my advice helped... but also using the secret code in the Dialer would've verified if your carrier supports it on their network, beforehand; that's why I posted in that step...
also, just as a reminder; I'd make sure that there aren't any hidden fees associated with using those features, I don't know much about US carriers; aside from that they are (generally) against Net Neutrality.... But I know with my particular carrier, in Canada; If i wasn't using the plan that I am on; they would be charging me extra - and it would add up quick... so best to double check, maybe.

I came to this phone from a s7 edge that had VoLTe and Wifi calling on it never got charged for anything, would it be different with a non carrier phone?

I have no idea: I live in Canada and have never dealt with US carriers ~ that's something that you will need to verify on your own. Some may allow it; some may not... you guys do things quite a bit different south of the border, so I just don't know....
You should be able to find that out in the support/QA area of your Carrier's website ~ if not there, you can ask them directly.
but yeah, obviously, if it was working on your S7 - then your network supports it....

Hello, I am on Vodafone UK, recently my area is getting poor 4G coverage so the vodafone tech guy asked me to shift on wifi calling inside the house. He enabled it from carrier perpective but I have to enable it on handset as well. I struggled to find the option. Now using the secret code above I can see I have wifi calling option greyed out. btw, I am on stock android 8.1. What is the best and least intrusive way to get the wifi calling working on my handset.
I am not a developer but have experience with root on previous devices. If I have to install Magisk( is there a non-root option?) what module etc I need to install to get this working please..

Flash magisk and get the module called VoEnabler just sear h VoLte in the search bar it should pop up then after it installs restart phone and you should have the options.

Hi Praveenjohri - did you get this to work?
I too have a Pixel XL and on Vodafone UK; again the wifi calling option is greyed out.
Any layman guides as to how to Flash magisk and go about enabling this? Thanks in advance

Sprint Moto Z2 Force on Ting (WiFi Calling Missing)

I recently purchased a new Sprint Z2 Force and activated it on Ting (it has only ever been on Ting and never on Sprint directly). Both Sprint and Ting support WiFi calling on this phone, but WiFi calling is not listed under the WiFi settings or in the Call settings of the dialer. However if I search in the settings for WiFi calling, I can see a WiFi Calling Settings in the App Info section, yet there is no way to turn it on or open those settings. I have updated the profile multiple times and also did a factory reset.
Am I missing something or is there something missing in the software since it never got activated directly on Sprint?
Any help/suggestions would be appreciated.

I do the custom rom thing and i sort of remember it just being there however, if you have not already checked "Mobile Networks" - under main phone settings, select "Network & Internet" once there, select "Mobile Network" - you'll see your carrier stuff/APN there I believe if you select "enhanced 4G LTE Mode" (you may have to make LTE you're preferred network mode in order to enable and/or display that option, again this was already there on mine. But see if that opened up any new menu items elsewhere i.e. back in the dialer app settings under "calls".
Did your phone come with a sprint SIM? Do you have the other carrier bloatware on there like Sprint ID? I know what you meant earlier about a possible software bypass, but all of that stuff is deff on the phone somewhere like you observed in App info, it may just be a matter of popping in a sprint SIM card to unleash it..

I continued to look into this for you. Sprint's name for Wifi calling is, well was -"Calling Plus". I found this article that advises one of the recent update removed the feature;
https://community.sprint.com/t5/Buz...alling-PLUS-Service-Decommission/ba-p/1017775
Since you got the sprint version you still have lots of software modification options. I also have sprint z2 foce, but I get better coverage on a GSM netwrok so my device is half sprint\half tmobile and I can deff say the wifi calling works. There's tons of information on here I can always help direct ya, but at least you're not crazy it WAS there.
lastly just to be sure, this has to be done prior,
"Log into your Ting account online and go to Device settings. Find the device you want to enable Wi-Fi calling for and click the edit icon in the Minutes section."

Thank you for all the info so far! Here are some answers and additional info:
My phone did come with a Sprint Sim in it and that is the one I am using. Also there is not any of the Sprint Bloatware on the phone. If I search "Sprint" in my settings area, there is a My Sprint Launcher that is listed as Disabled and there seems to be no way to enable it, which is similar to the WiFi Calling Settings that shows up when I do a search for it in the settings. Also if I look at the Apps and "Show System" apps, Mobile ID is there which is the Sprint ID software I believe, but again it is Disabled with no option to enable it.
The WiFi calling is turned on in the Ting account.
The Calling Plus feature was disabled by Sprint in that link you shared, but that just disables WiFi calling over LTE. It does say regular WiFi Calling should be available.
On my phone when I go to Network & Internet > Cellular Networks> I see my Preferred Network Type which was Automatic, I switched it to LTE/CDMA. That does not seem to have opened any additional settings for me in the dialer or elsewhere.
Thanks again for all your support. If you have any other suggestions, let me know, but you have offered a lot already.

Question How to change preferred network type?

I'm on EE UK but the preferred network type setting doesn't appear to be present in SIM options?

It appears that some providers suck hard and don't want to allow you to switch networks. That's not a phone thing-y, it's a provider thing-y. Which means that your phone will of course still change networks, but only if the "higher" one is not available, ergo your phone will only connect to 4G, if 5G is not available - if the 5G connection is bad, that will probably cause problems for you, because your phone will probably not want to connect to 4G automatically.
I can easily switch preferred network types
Settings -> Network & Speed -> SIMs -> (scroll down, between 4G Calling & Carrier settings version) -> Preferred network type (5G, 4G, 3G, 2G).
It that's not available, your network carrier sucks. No more to say here.
I'd suggest you either switch providers, or contact your provider to see if they are willing to change this. It's definitely on their end, cuz people like me can change the settings easily.

Or you could just make sure Adaptive Connectivity is enabled and not worry about it.
You would have to drag me away from EE (BT Mobile) screaming and kicking given the coverage and speeds they have, to say they suck over one menu option missing is absolutely laughable.

When the Note 20 first came out a lot of carriers wouldn't let you change network type but there's an app in the play store that was working on the notes.

Crashes or alternately just disappeared for me when I click on the first option "4G LTE with only one SIM". Reported the crash. Thanks, though. Maybe they'll update it.

An alternative to the dialer code is to boot into safe mode, and the preferred network type setting will appear in: Settings -> Network & internet -> SIMs between Data warning & limit and Carrier settings version (at least it does on my Google Fi Pixel 6 Pro).
