Add Wi-Fi calling?

How can I add wifi calling to a ROM? I remember back in my G2 days it was an APK I could simply install... but now this is more baked into the ROM.
I REALLY need it and have been dealing with their tech support to reset the "iHLR" settings. I've switched out my SIM but the TM number doesn't match what I've researched works best with Wifi calling. I've done a good bit of forum searching for anything and every single result didn't have one instance of even the word "calling".
And now my favorite ROM doesn't have wifi calling :crying: lol

WiFi calling on TMobile is terrible. I'm not sure if that was fixed in the latest update. As for porting the WiFi calling feature to other ROMs, it has not been done yet since TMobile has integrated it into the framework (and it works horrible so there is no incentive).

I've never had a good experience with it either, but I need it so bad Stupid feature

It's more than an apk now, it's a couple of lib files.
Wifi in the latest release seems a lot better than the older.

Does Venom's Rom support it? It comes up when I do a "Wifi Calling" forum Search. I don't see it where it usually is, but I did de-sense it so I'm not sure if that effected it or not.

Mi band and OnePlus

Can somebody make unlock function of mi band in cm11? Any idea how is possible port this function to the OnePlus?

I'm curious too. I currently own a MiBand and everything works fine.
I think we'll have to wait for Android L which supports Bluetooth LE unlocking.
Currently, it works with a Tasker profile, though it's often a bit slow and can take up to 5-10 minutes untill it realises that the Miband is there / not there. On the other hand, if it's security you're thinking about, it may be a solution.

can you link where u got the mi band from? and what price you paid?

I got mine from ibuygou and paid 30$ for it. Though there are other major Chinese sites that sell it (like Banggood, ...)

For now there's no solution for truly proximity-unlock as in MIUI.
But for other phones only near solution is Xposed-module No Lock Home (all other apps non-functional for reasons).
It will to enable secure lock-screen if no connection with bracelet e.g. you lost phone = distance over 10 meters.
When Mi Band connected in module settings once tap "plus" icon > Bluetooth (MAC address)
This will fill MAC-address in field below and auto-locking will work.
Experiment with other settings too and don't forget to donate to author of module.
Maybe sometime he will add unlocking based on signal strength from band as in MIUI: I posted feature-request.

Did no lock home work for you? I thought it didn't support bluetooth le?
Currently i'm using tasker profile but it's sloooooow

Will this work if we use MIUI ROM?

Just Wondering if this will work if we use the MIUI rom for oneplus?
I havent got mine yet. Waiting for it to arrive.

On cm12 (android 5.0), smart lock with miband actually works!

works on OnePlus CM11s

Wi-Fi calling - HELP

I recently got a Xiaomi Mi5, the stock ROM does not support Wi-Fi calling, so I needed to flash it since I work in a basement...
I now have Resurrection Remix installed, and Wi-Fi calling is available and toggled on, but it does not actually work!
I know it is enable on my sim because I have been using the feature for a year on an iphone... and the provider confirmed they did not lock anything up or needed to reset anything.
Any ideas out there?
I can't think of any way to even debug this issue, apart form flashing to different ROMs, but that takes a while and I like RR.
Thanks

VoLTE and VOWiFi not working on Xiaomi.eu

In the first week of having my Note 10 Pro, I was using the global ROM that came with it, and after foricng volte and vowifi on with the dialer codes they were both working, I still have call logs in my phone showing it was working.
But, after the week when I was able to unlock, I unlocked the phone and moved to miui 12 on Xaiomi.eu, and both these functions no longer work, IMS status shows unregistered.
Does anyone know if this is a fault of Xaiomi.eu or the Chinese ROM? I haven't had much time to bother with switching around ROMs as I've had to be using my phone, but if someone already knows this will only work on global I'll probably switch back.

Updated to Xiaomi.eu 20.5.14 and the issue persists.

I am using volte and vowifi on Xiaomi.eu 20.5.14 without any problems.
I didn't change any settings, it was just active when I started the phone first time.
Using provider 3.AT
Maybe not all carrier settings implemented in the ROM.

It's definitely to do with carrier, I'm on Tmo in the US. As I said in global it worked with nothing extra, so I think xiaomi.eu or the China beta is missing some configs or something.

Volte is disabled for some countries.
It should be enabled by

I've already done the dialer codes, the build prop edits, checked the APN, tried the PDC tool, nothing works.

Issue is still present on 20.5.21, I think the Chinese beta or xioami.eu might be missing the proper modem configs for tmobile US, haven't been able to test on other ROMs (miroom, revtech, masik, etc), but I might have to stay on global on this phone once global miui 12 comes out :/

I'm on T-Mobile here in US also and it's not working. I also get a few calls that go straight to voicemail since using EU now. I might try miroom haven't heard of revtech.

I made some progress!
After flashing the firmware from here https://forum.xda-developers.com/mi...rmware-xiaomi-mi-note-10-pro-mi-cc-9-t4096347 after a first boot the wifi calling icon appeared for a split second, but VoLTE was enabled! important to note, volte icon will only show in the status bar with the control panel pulled down (right side panel).
After some testing, I was able to get wifi calling working too, but only in airplane mode. With airplane mode enabled and wifi manually turned on, after a few seconds wifi calling appeared and calls connected, but as soon as I turn off airplane mode wifi calling goes away and it switches to just volte, even starting a wifi call and then disabling airplaneode would convert the call to a volte or regular call, very strange!
If you're going to try this yourself, you can flash any firmware from the eea or global rom, but to avoid breaking your fingerprint scanner, after flashing the firmware and rebooting, make a backup of your modem in TWRP, and then flash the 2.5.14 china ROM firmware back, reboot, and then restore the modem backup. You'll probably still have to re-register your fingerprints, but it's better than nothing!
I've attached some screenshots for proof

About to try this
---------- Post added at 05:35 PM ---------- Previous post was at 04:39 PM ----------
So after I flashed global firmware, I got icon for about 10seconds after a reboot in airplane mode but it wouldn't make a call. My Google messages now allows the rcs chat option though

Do you have volte/VOWiFi force enabled? That's the only thing I can think, volte works with no extra steps whereas VOWiFi only works with airplane mode. I'll try sending you my TWRP modem backup maybe that'll help.
Edit: here's my TWRP backup of my modem https://drive.google.com/file/d/1--fGb80OjIdJpUzkgiKlHhlW9oykjyme/view?usp=drivesdk you'll need to unzip it in /sdcard/TWRP/BACKUPS/<random letters and numbers>/

So I just did a reboot again before doing anything else and it works.

Awesome! Now we just gotta figure out how to get wifi calling consistently working.

Mine was on for about an hour today

I'm going to make an educated guess based on your signal being very poor in that screenshot; It's possible there's a change in MIUI 12 causing wifi calling to only be enabled in poor or no reception areas, which would line up with me only being able to see it on in airplane mode.
I'll have to figure out some testing for this myself, I suppose this change isn't too illogical, you'd probably only really need it in those cases, just kind of off-putting/misleading that the behavior changed between versions in a way that made it seem broken...

Let me test that theory, I get poor signal in the basement and great upstairs so let me see if this is indeed the case

Just a little update on this, today my phone started getting some spotty cell reception, and wifi calling turned on! There doesn't seem to be any threshold (i.e. past two bars or less, it turns on), just while the signal is poor it will arbitrarily decide to turn it on. Some undocumented miui 12 feature I'm guessing, since it didn't act this way on the stock miui 11 ROM the phone came with.
Also something maybe interesting of note, I was curious and connected the phone to the PDC tool and it said I was on a T-Mobile modem, as would be expected I suppose, it's just strange why the stock xiaomi.eu modem will not show this modem option even when manually imported to PDC.
On a slightly related note, I put my sim back in my Mi Max 3 running miui 11 still, which previously only had volte available, I tried the same process as what I did on my note 10, I flashed the firmware from the global and EU ROM to see if wifi calling would become available but no dice, so it seems this solution isn't fullproof for all devices just ours.

I saw only this code
This is for WiFi calling
*#*#869434#*#*

I disabled using *#*#869434#*#*
After that I could go to my sim card and enable it, and choose if I prefer wifi or mobile network.
These options have not been availble if i enable using *#*#869434#*#*

hello guys i put the xiaomi.eu rom on my 10 with the android 11 global rom and MIUI 12.2.0.6 i had the icon voLTE ene call log marked me call HD or want to know if a bug because I don't see plus the voLTE icon in the status bar and neither the HD and voLTE icon on the call log

Question Anyone having issues with VoWiFi NA version?

I just got the NA version of the ROG Phone 5 and sadly I cannot get VoWiFi working on TMobile. Sadly I'm in an area where I don't get the best signal and it's extremely important for this feature to work. Especially considering I spent 1k+ for this phone... Any help/guidance would be appreciated.

Have you enabled it in settings and then tried a reboot?
I've also noticed that it may not work until the SIM is installed BEFORE initial setup (or before a factory reset)

I confirmed with other people too. US version doesnt have Tmobile wifi. If it would, I would have bought one

Yeah I tried that but didnt work so i manually enabled it using the phone dialer and after i toggle it on or off it will turn on but it turns off after reboot so need to root it so i can make the settings stick.

Yup just have to manually enable it Everytime it boots up but if you root it you can set the props and it will be permanent. In the process of doing that atm.

You should be able to copy and paste if that doesn't work try pasting but delete the last * and add it manually. If that still doesn't work just manually type it in. But I tested it out a few times nd it works even turned on airplane mode and it works. Wi-fi calling was a deciding factor for me lol was about to return it until I found out I could get it to work properly.

I'd like to add that after running the dialing code you have to enable wifi calling in the settings app.
Aswell as that, at least for me, I need to disable and re-enable it within settings after re-running the dial after reboot, for it to actually reconnect
Just to avoid any confusion.
This does work tho! Kva is right!

I agree, but idk if they need some authorization from T-Mobile to enable it by default and we're just the end user working around that.
Otherwise, I'm not really sure at all why the functionality is developed but not enabled by default.

Yeah it's stupid I ended up talking to advanced tech support and the guy has never heard of ROG phone 5 and said I should return it cuz it seems like it's a hardware issue.... I'm like dude it's your system not giving me proper access's and authorizing my phone... He's like I guess you know more about phones than I do... The idiot even made me reset my phone to try and fix it even though I told him several times that has nothing to do with it.... I swear I have no idea how some of these morons get jobs as IT... At least have basic IT understanding....

They're not in IT. They're customer service reps. They read from a script.
Check out the movie The Internship. It's just like that.

Well, when I'm talking to the advanced Technical team I am not talking to customer service reps... I talked to a customer service rep and they forwarded me to the IT team. Considering they are called advanced technical teams I would assume they are in IT. whereas the initial person I talked to was and clearly stated she was a customer service rep.

The only difference between the two people you spoke with is that one had access and authorization to suggest more "advanced" solutions. I'm not saying they shouldn't have better training, but legitimate IT professionals rarely work the call center as more than a summer job.
Anyway, the point was that they're a waste of time unless the issue is the SIM card or your plan. It's unfortunate.
Dial codes typically trigger an intent. If you can track down the intent, you can have it launch automatically on boot. Once that's taken care of, it shouldn't be too hard to automatically enable the setting. That is assuming you called because setting the prop didn't work.
Another alternative if you do have a property and can't write to system is setting it with a magisk module, since the system is read only on a firmware level.

How would I set that up using magisk module? One Issue I have noticed is the wifi calling turns itself off after a while. sometimes it works for several hours other times maybe a day but then turns off and I have to restart the phone and run the command again.
