VoWiFi (Wi-Fi calling) Moto G 2015 Osprey

Hello All,
In my new home is very low T-Mobile signal strength.
As i know from carrier official page, T-Mobile supports VoLTE and VoWiFi (Wi-Fi calling) in my country.
Now (6 july 2017) i have installed newest LineageOS build. There no option to enable Wi-Fi Calling/VoWiFi, but regarding to official Qualcomm site Osprey's processor (Snapdagon 410) supports Wi-Fi Calling/VoWiFi:
Next-generation Calling Services
Voice over Wi-Fi (VoWiFi) with LTE call continuity
HD Voice over 3G and VoLTE
It is posible to enable Wi-Fi Calling/VoWiFi on Osprey?
This solution does not work. When i make Wi-Fi Calling enable it going back to off.
Device: Moto G 2015 (XT1541)
Country: Poland
Carrier: T-Mobile
ROM: LineageOS 14.1 build from 6 july 2017

FYI For U.S. prepaid T-mobile accounts: T-Mobile may require address and other information to be entered on their website into the account profile for that phone #. If that information is entered on-line and the account has WiFi calling properly enabled it should work when the device has wifi connection and no cellular connection. This is not dependent on any settings on the phone and should work even if you don't see any settings there. You might want to contact your provider about this.

No, it doesn't work, not with T-Mobile. It won't stay on, no matter what you do.
I have MetroPCS/T-mobile USA, and I have had the exact same issue. I've had no problems using wifi calling on my same account with other phones, but not this one (they do require you to register your full info here, as the last poster said). T-mobile support themselves have told me, however, they only allow wifi calling on phones purchased directly from them, and that's why no go, at least not in the USA. I'm assuming that's their policy in other countries, too?
I don't know if there is a hack/workaround.
Side note: When I go to Europe, which is often, I re-register my old, official t-mobile phone with t-mobile usa, leave my US sim in it, and I use that phone thru wifi calling to still have a US phone while there. I throw a UK sim in my Moto G to use every day.

From what I understand, I could be wrong though, T-Mobile open sourced their WiFi calling and anybody can implement it but LineageOS haven't done it yet. It's a matter of adding the code (just like VoLTE) I think. I don't think T-mobile checks if it's their phone or not, the right software need to run, that's all. The problem is that the software is very low level and needs to part of the kernel, you can't just install some app and make it work. This is what I found when I did my search for LineageOS and WiFi calling a few months back. from T-Mobile forums. Of course anybody can post anything in those forums so it's not official or anything but a few users provided the same answer (some seemed quite knowledgeable) so I believe this is it (probably better than talking so some phone rep reading off FAQ's haha)

It's not unheard of for mobile providers to do just what I'm suggesting t-mobile does. In the UK, for example, Vodafone limits WiFi calling even further than that, to only a few select Voda-sold models (or at least it was like that when I was there recently).
I would very much appreciate being pointed in the direction of guidance by anyone who's been successful in getting it to work on any non-tmobile handset, custom ROM/kernel or not. Thanks much x

Hi IronTechmonkey, at first I took it as a fact but later I thought about it and now I'm thinking how would WiFi calling work without LinageOS having code for it. Once you're outside of their network and T-Mobile (others too of course) can't get to your phone through SIM card the only way for anything to work is if the software on the phone through the internet first contacts the provider, correct me wrong but how would the provider get to you? This is just my thinking about it so I'm not sure but what common sense tells. I have the address on T-mobile and everything setup but since I'm not NJ where coverage is everywhere it's not easy for me test it but I'm scared without LineageOS actually getting on top of it and implementing the code it's not going to work. I'll test it once I go somewhere with no coverage but haven't had a chance yet.

Good question. I wasn't being quite clear enough in replying, and was speaking to whether or not there would be settings in the ROM if the feature exists, but was not speaking to whether or not the code is present. To the point of your question, from general web searching this seems to be device/ROM-build specific but when I search specifically for Lineage OS Osprey wifi-calling I find this thread. LOL. Apart from that this jira ticket for a different device is all I can find: https://jira.lineageos.org/browse/BUGBASH-508.

Thanks, so I'm confused now, and thanks for your help. I know with VoLTE it was such a big deal we had whole posts about removing it and then bringing it back etc... all the updates and drama we need while nobody mentions even once if this device has wifi calling or not, haha, weird

I want to reopen this thread, I tried to ask in the official development opsrey thread but was sent to Q & A, so I'm reopening this thread. Anybody knows anything about Wi-Fi calling for osprey and LOS? Will it be implemented? Can I make a request somewhere? Maybe just switch to LOS 15 when it's official, will it have it on the arrival? I traveled outside of the US and did different tests and couldn't get Wi-Fi calling to work? Here's my post from the official osprey development thread with more detailed, thanks you, https://forum.xda-developers.com/showpost.php?p=73769962&postcount=5299
BTW, I made all necessary changes back in the USA with T-mobile to make Wi-Fi calling work, thanks.

So, WiFi Calling is unavailable as default option on any of ROMs for our devices.
BUT
For example, in Poland everybody who has Android higher than 4.1 can use "WiFi-calling" on "Orange" carrier. This carrier offers some application which realy works:
https://play.google.com/store/apps/details?id=pl.orange.vowifi&hl=pl
Functionality of this app is same, but i think it drains more battery than "wifi-calling" implemented as driver in kernel.

Thanks mrViZhy, actually I'm traveling from USA to Poland too. What I would like to do is keep the US number and receive text message (and pick up phone calls too) from US. I'm assuming your solution requires getting Orange number, if that's the case it would break the connection that I have with the US.
Thanks again for your help

Wifi calling UK?

Does anybody know if the OP6 will support Wifi calling? More specifically in the UK?
I think someone once mentioned to me that the OP5 had Wifi calling on Three UK?

I would also like to know this answer.

I'm with three UK, and had WiFi calling on my Note8.
Unfortunately nothing has come-up on the OP6.
Will keep you updated.

WiFi calling on O2UK

You see WiFi calling as an option on OP6?

Is the option there? User above has shown Wifi calling option is certainly there and works with O2.
I have Wifi calling on my Honor View 10 and that works with Three.
As OP6 doesn't appear to need special firmware to have Wifi calling, unlike say a Samsung S9+ - I would assume it's there?

Odd. I would have thought the option was available to everyone - as the OP6 isn't carrier specific and doesn't have special firmware.

its up to your mobile operator which devices to support

Not the point we're trying to make. The option for Wifi Calling in menu will be there regardless of whether the operator supports it. Some phones need a firmware from the operator to see it. But shouldn't be the case with the OP6 as there are no other firmwares, it's independent.
Nokia 3/5 - has Wifi calling option (as does iPhone) whether operator supports it or not.

That's worrying, I rely on WiFi calling in my flat right now since I get no signal at all (very thick concrete walls).
WiFi calling works flawlessly on Three on my iPhone, so if it turns out Three doesn't support it on the OP6, I might have to switch to O2/EE, both of whom have WiFi calling that works with OnePlus.
I actually went on live chat with Three a few days ago to complain about the lack of signal and WiFi calling not working on some Android devices - they first said to just use the Three inTouch app, to which I said it is garbage and barely works half the time. Eventually they caved in and gave me a £3 discount on my monthly bill. When I didn't accept that, they gave me £4... and then £5. Eventually they sent me over to the complaints team who gave me credit on my account equivalent to 2 months worth of bills and said I can cancel the contract free of any charges whenever I want.
Point is, if WiFi calling doesn't work on the OP6, go and complain to live chat, you'll get a discount on your contract or even better... and do not accept the initial offer they give you.

spoke to soon, they have waived my upgrade fee of about £120 and are referring me to the upgrade teamn (sim only contract) as my contract runs out in a few months, i can also cancel without the fee right now if wanted aswell. can anyone confirm if EE has working wifi calling on OP6

By default HD must be on to make and receive calls.
I don't know about WiFi calling. Never had a desire to use it or a need.

I do alot of work in a deep basement that has wifi but cannot get a signal from outdoors.

No VoWifi
I can confirm no vowifi. I'm on VZW. HD voice does work tho.

Yeah, VoLTE works but not VoWifi. Even when manually adding the option to turn VoWifi on, it doesn't work. I get crap service in my house but great service outside my house. I asked tech support about Wifi Calling and if it was provisioned on my account, but I was told if the phone can do it, the option will appear. I told them it can and it was working for another carrier. They said they don't know why it's not working. I didn't have time to stay and troubleshoot the issue though. Luckily the tech support person offered me an LTE Network Extender 2 for free. I have to wait until 10/16 for them to get more in stock though.

I really want this phone but I cannot buy it if WIFI calling (VoWIFI?) isn't working with Verizon>
Thanks again!

Verizon does not allow Wifi calling on devices it does not sell. So a Note 10 from Verizon has Wifi calling but an Unlocked Note 10 does not.

Wi-Fi Calling

New to this forum. Just got my Motorola One Hyper today. Am I able to make wi-fi calls on this phone? When I go to my Settings, Wi-Fi Calling is grayed out. If I long press it, Wi-Fi Calling comes up, but again, the screen is grayed out. It will not allow me to enable it. I am connected to my home wi-fi network, so that is not the problem. Thanks in advance.

It depends on your carrier, call customer service and ask if they use wifi calling. It works for me on T-Mobile on both stock and omni out of the box.
Beyond that, make sure you are updated to the latest stock firmware. The last update fixed volte and vowifi.

Thanks for the response. After the phone went through all of its updating, the wi-fi issue solved itself. But I have another question. This phone was labeled as "International version" when I purchased it. I discovered that it's actually (RETLA), thus the instructions only came in Spanish. Will this be an issue using it in the USA?
Thanks

What's the model number?
Mine is xt2027-1
If it's xt2027-3, you might be missing some lte bands...

Go to the link below, it compares the bands different models of our phone operate on. If more bands are compatible with your network, your network reception will improve.

Wifi Calling in pixel 3xl

Hi,
I have pixel 3XL and i want to enable Wifi calling.
I have searched in my phone setting ( system settings>network and internet>mobile network), as well as in the phone app, and this option does not appear to me.
My carrier has this feature and i want to use this feature, but i don`t have this option.
I also looked in the secret menu(*#*#46...) of phone info and i see the VoLTE provisioned and wifi calling provisioned are on grey.
Can anyone help me how to enable this feature ?

There appears to be known issues with Pixel phones not able to use WiFi calling with AT&T out it's MVNOs.
For example red pocket AT&T service and cricket wireless both don't seem to allow WiFi calling unless you do some tricks like updating IMEI in their records.
Hope to hear from other members since I'm experiencing same issue.

I have spoken with the carrier.
They support only Samsung and Iphone, but he said he enabled this option for me, but he said he does not believe it will work.
Does anyone have an idea if there is an option to enable it via the phone with some kind of bypass ?
