T-Mobile Wi-Fi Calling Issues - Nexus 6P Q&A, Help & Troubleshooting

Anybody else having issues with T-Mobile Wi-Fi Calling? Mine connects after a reboot, stays connected, but after a while it disconnects from WiFi calling and more often than not it doesn't want to re-connect again until I reboot the phone.
I suspect it may have something to do with the Doze mode in Android M, but I'm not sure. It feels like once it gets in doze mode it doesn't want to connect to Wi-Fi calling again.
Any known ways to force it to reconnect to WiFi calling, without rebooting?

Not sure what's happening, but I'm not receiving incoming phone calls when connected to WiFi calling. I've turned it off at home (have decent enough voice service) for the time being.

I've seen that too, it's definitely flaky.

Came here just to get more info on this issue. Flaky on mine as well. I'm on T-Mobile. Sometimes users will hear me well, sometimes they cannot. It's typically most flaky when I'm right on the cusp of getting a tower signal. I'll receive a WiFi call and all will sound fine, but as soon as I move close to a window the call quality drops and users on the other end can barely make out what I'm saying. Almost like it has a hard time deciding between WiFi or the cell tower.

Do you have it set to prefer wifi calling?

First day in office tomorrow on a 6p, will test this.

I've had it set to both at different times in the past few weeks. Right now it's set to prefer WiFi because I have poor to non-existant celluar coverage indoors (both at work and home). My wife's old LG G2 has flawless WiFi calling at home.

I have mine set to "Wi-Fi Preferred". It's worked without any problems that I know of both at home and at work, for both calling and text messaging.

This has also been my experience, Connects instantly and stays connected. This is also the first phone I have had that actually hands off to mobile network when leaving a WiFi area without dropping the call. The galaxy s6 advertised this but never once did it work. I get pretty good service at my house and honestly didn't know that I would be able to use WiFi calling when I bought my 6p. Pleasantly surprised.

After a few days, text messages won't send. I get an error -1 code. Had to turn off Wifi=preferred.

See whether this helps:
Dial *#*#4636#*#* as a "normal" call from the stock phone dialer
You should see a menu
Tap Phone information
Scroll down
Tap "Turn ON SMS over IMS" button (make sure that after the button actually says "Turn OFF SMS over IMS" -- this means it's currently ON)
Based on info from this thread: https://www.reddit.com/r/Nexus5/comments/1vahlr/fyi_if_youre_on_tmobile_your_sms_is_sent/
I would not touch any other settings in that menu and if it doesn't help, you should probably revert it back.
Now I'm not sure where these settings are persisted and if they get reverted back when a new radio is flashed for example. Does anyone have more info?

It works but I've found that it causes my phone to stay awake, so I've turned it off. I'd rather lose 1-3% overnight and not 8-10%.

Gave it a try and re enabled wifi calling preferred. I'll post an update, but the error usually takes a few days before showing up.

My Wi-Fi calling was working fine, then I flashed the update to 6.0.1 and it doesn't work at all. It's enabled in settings, strong WiFi signal, but it never indicates Wi-Fi calling.

I had the opposite experience, I updated to 6.0.1 and now WiFi Calling is a lot more reliable than before. Still not perfect, but much better.

"Ready to connect when network quality improves"

Hi guys,
Getting this message upon connevting to virtually every wireless network sinse rootibg my phone, is there a root tweak to disable betwork quality checking ? On a G900F
Thanks
Anyone?
You should be able to turn off smart network switching under wifi settings that will solve it.
Nice one thank you! I will see what happens!
turning off smart networks helps, but if the wifi signal is too poor it will not connect anyway

ready to connect when network quality improves
We have two Galaxy 5s in our home (AT&T and T-Mobile). Both just started getting this message last night. "ready to connect when network quality improves"
Its multiple access points, multiple networks. Eating battery like crazy. Dropping and reestablishing connections to WiFi every 15 to 60 seconds.
Pain in the @zz
Turn off "smart network switch"
I also started getting "ready to connect when network quality improves" messages constantly as the network connected and disconnected. Turning off the "smart network switch" option fixed the problem. I also leave the annoying Samsung Connections Optimizer turned off.
Smart Network Switch Off?
I just got my S5 about 6 weeks ago. I have had NO issues until this week. A few days ago, even though wifi notifications were turned OFF - I kept getting this "connected to network name" message on the bottom of my phone. When I went into wifi settings this morning, I noticed it would switch from connected (very strong signal strength) to "waiting for signal quality to improve". It constantly goes back and forth - 5 seconds or so on each. This is not an issue on any other device connected to the wifi router at my home and I just tried it at work - happens here too.
I checked to make sure wifi notifications were off - they were - but the pop up still appears over and over. I think that's another issue separate from this because if notifications are off you should not be getting any!
I have done as suggested here and turned off the smart network switch, however, does that now mean that I will be switched back and forth every 5 seconds from data to wifi? That defeats the purpose of connecting to wifi to save on monthly data plan charges.
AFTER noticing this problem this morning, I went to see if there were any software updates - there were (Lollipop). I did download that, but no change.
How does turning this off affect where my phone pulls from? Uses data or wifi?
Thanks for any help!

+1 with exact same timelines/symptoms and upgraded to Lollipop and no diff too.
I started getting this message on my S5 last night! The connection will hold for about 10-15 seconds before reverting to LTE.
Tried resetting router settings, playing with different wireless settings - changing channel width and turning the visibility on and off.
Then "forgot" the network and readded it again.
It seems to be holding a stable connection without it dropping and was able to download a few items from the play store without dropping.
Will update if it changes.
Same here S5 900F

Me too - I've been searching for weeks to figure this out - tried every known fix .... nothing has helped. I've even reset/changed/updated my wifi settings on my router. Nothing has helped. My S5 is the only one that has this problem. Other phones in the house have no problem - S4 and others.... I just don't know whats going on. I maxed my data avoiding this issue - but I really need a fix for it.

This problem was driving me insane......I had it and managed to fix it (hopefully been going ok for three days now) I have a samsung Galaxy S5 on EE.....I backed everythingh up and did a factory data reset. Hope this helps.
I have a Galaxy S6 and have the exact same issue. I have called Samsung, my carrier (US Cellular), and tried a local place to get it fixed, but no one has ever heard of this issue. Amazon Photos was hogging a lot of bandwidth and backing up on wifi only so I stopped using that. Still not much of an effect. Using FB or a video is almost impossible because they won't load or refresh. I've tried all of the suggestions, but don't see a final fix. Can anyone help? This is my second S6 with the issue.

Wifi-Calling T-mobile?

Hello Everyone,
Does anyone know if this phone supports Wifi-Calling via T-mobile?:cyclops:
It does. I tried it last night. Turned to airplane and turned back on wifi, made a call just fine over wifi on T-Mobile.
I had no idea it could do that, but since my house is a bit of a Faraday Cage my G5+ starts the call as a provider call (T-Mobile) & jumps over to WiFi as soon as the connection is made. Totally threw me for a loop, I've wanted this feature on an OON phone for several years... way to go, Moto... oops, I mean Lenovo
Dave in San Jose
I might be missing something but it doesn't say WiFi call when set to WiFi preferred and I'm on WiFi. I try turning airplane mode on and WiFi on and get a message that I have to connect to a network. In TMobile.

Did you enable it in settings? I've found it to be a little finicky sometimes, but it usually works pretty well.
It works but for me caused SMS/MMS delivery issues with the wifi router i was on. So i turned it off. I can turn it on when i need it for now, no need.
Get an sms app that supports forcing sms over cell even if you are on wifi like textra.
Sorry to bother, but it doesn't work for me. I have wifi preferred and wifi calling enabled, but it doesn't work when I do airplane mode-with-wifi on.
Any chance this could be due to APN settings? Can someone with this working share their APN? I know on my previous phone (Nexus 6), the T-Mobile APN settings were confusing and tricky. Thanks in advance!
Turning on airplane mode got wifi calling and SMS to work for me no problem. I have "wifi-calling preferred" selected in settings - is there any good way to get it to switch over automatically when cell service is poor? would like to not have to hit airplane mode every time.

Actually, you shouldn't need to turn on airplane mode. That seems to just be a way to confirm it is actually using wifi since it ensures cell radios are turned off. It will automatically switch if you do not turn on airplane mode. If you look at the phone when a call is connected, it will confirm that it is a wifi call. This is a small drawback to the Moto G5 Plus software. Unlike other phones that actually tell you that the phone will use wifi in the notification area, this phone only acknowledges the wifi calling after the call is made or received. It would be nice if they would change that.
However, I am having a problem with mine not working properly on wifi. It seems that calls will not always go through to my phone. The phone will ring, but won't let me answer the call. It will quite often show the same call repeatedly even though I cannot answer the call. The caller tells me they hear nothing the entire time it should be ringing and eventually gives a busy signal. It doesn't even go to voice mail so they can leave a message. Sometimes it works perfectly, but there is no way to know when it's not going to work. I used to be able to get it to work again if I switched off wifi and connected to LTE, then made a test call before turning wifi back on. Now I can't seem to get that to work any more. Anyone have any idea what could be causing this?
Hi brothers,
Please, can you share some screenshots of these VoWIFI options in settings?
I feel the "reteu" (european) version doesn't have enabled VoLTE and VoWIFI.

Wifi calling - inconsistent with 8.1 Oreo - T-Mobile

I'm finding that WiFi calling stops working randomly. A reboot gets it to work properly again. I have my advanced call settings on Global and Wifi Preferred as my option.
Anyone else having this issue with Oreo 8.1 and T-Mobile?

I've had this issue since I upgraded to 8.1. I've been planning on doing a factory reset to see if it fixes the problem, but I really don't want to go through the hassle of setting everything up again.
I have no cell signal at my desk at work, so I use the WiFi calling often. However, I have noticed something rather strange. If I try to make a call or send a text, it will sometimes say something like "No WiFi network available". There have been a few times after it has done this that I have received a call on WiFi, and then it will work fine for a while. Otherwise, a restart fixes it.

Another thing that I noticed is that when on Wi-Fi calling, sometimes the phone will only ring once before a call goes to voicemail. Seems like there may be a delay in the call coming through. I generally have a good Wi-Fi connection, but like any Wi-Fi connection, it can come in and out occasionally.
I want to avoid a factory data reset as well.
I have the same problem Essential on Sprint
I am also experiencing this since the 8.1 upgrade, 8n T-mobile. Multiple networks that had WiFi calling pre-update are no longer functioning on either of our phones(wife and I both have them). I often work in a basement, so this is an important function for me.

Wi-Fi Calling T-Mobile USA (SOLUTION FOUND!)

SOLUTION AT BOTTOM
Seems like over the last day it doesn't want to stay connected to the Voice over Wi-Fi. If I toggle it it'll stay on for a few seconds and then the icon will disappear.
This is on both mine and my wife's OnePlus 8 Pro.
I've tried to restart device.
I've toggled airplane mode on/off
I've manually entered the APNs per T-Mobile's website even though the auto set ones by the phone were the same.
I went into *#*#4636#*#* and it shows I'm provisioned for Vo-WiFi.
I'm stumped. Is the network just being glitchy right now or is there something I'm missing on two different phones?
SOLUTION: Well in short OnePlus needs to send out a patch to fix this. How can you report a bug to them to fix?
Here's what I found out. Someone feel free to change your own router settings and see if the same thing happens:
My WiFi is set to WPA-PSK [TKIP] + WPA2-PSK [AES]. It doesn't work on that. If I set it to WPA2-PSK [AES] it works fine.
There are plenty of hotspots out there that are set up to one and some to the other. There's no reason it shouldn't work on either. Regardless, I changed the setting on my router and it's "fixed" but OnePlus needs to send out a patch or something.

That's definitely interesting. My friend down the street got the OP8P the same day as me. He seems to see VoWifi more than I do. If I toggle airplane mode, I'll get VoWifi for about a minute before it eventually switches back to VoLTE. I also am having some stability issues where the wifi signal is there, but goes bad... and the cell signal disappears altogether. If I toggle airplane mode, it goes back to normal (see attachments).
(EDIT: Not sure if both screenshots are showing, as the XDA app seems to be acting weird)
Okay this is DEFINITELY a OnePlus software bug I sent them an email via their customer support.
If I connect the wireless bullet z, wifi calling works and maintains a signal. I disconnect from all bluetooth devices and within a minute bam wifi calling icon goes out.
Updated original post found the "solution" myself. In short, how do you report a bug to OnePlus?

Wifi calling not working.

I received a new pixel 4a 5g on Friday. I have spectrum mobile and I can't get wifi calling to work. I have called spectrum twice and have gone to the local spectrum store. I have also chatted with a Google tech. No one can get it to work.
No issues with WiFi calling. Have you tried switching to airplane mode and re-eanable Wifi only? This switches on Wifi calling quickly on my 3a and 4a5g

Yes, I had this exact issue. Fix was to reset Wi-Fi, mobile & Bluetooth. Hope it doesn't return, but we'll see.
Hello all,
I also have a 4a 5g phone that I've been trying like hell to get working. Started with just seeing if I could find it myself. Found something in the settings (gone now), but it said something about WiFi calling. It happened to be grayed out.
Next step was calling tech support. They could help me and they convinced me that I have to change the sim card. OK change the sim card for using wifi calling. Whatever, the sim card arrived today and I swapped it out. Now I don't have phone service and I still can't get wifi calling.
My question is where is the setting for turning wifi calling off and on? I follow these directions;
How to Enable WiFi Calling on Android 11 Stock OS
Step 1: Pull down the notification panel at the top and touch the “Settings gear (Cog)” icon.
Step 2: Touch on “Network and internet”.
Step 3: Touch “Mobile network”.
Step 4: Scroll down and touch on “Advanced”.
Step 5: Tap on “Wi-Fi calling” in the calling section.
I follow the steps and it states my wifi calling is on. Yet when I call, it's is calling tech support. I've spent way too much time with dodgy tech support. Not sure what I can try at this point. Fortunately I have other telephone options, but not my main.
Any help would be greatly appreciated.
Us3r_1,
I followed your steps 1-5 on my 4a5G and on T-Mobile and Vodafone it works for me.​

Sorry for the confusion here. and thanks for the reply. OK it shows that my wifi calling is on, I don't have any phone service at the moment. Regardless of what number I call, it goes to the step through for getting to different options, like activate phone, change number, and so on. It seems like I have to turn off the phone connection to get wifi calling to step in. BTW, this SafeNet which I think they use Tracpone.
EDIT: My service is not SafeNet, nor SafeLink, but is Net10 on Tracpone. Not for long though.
You're welcome.
BTW: On my 3a I had to restart the phone from time to time. Perhaps this helps in your case.
Double check with your provider that WiFi is switched on for your account.
Yeah I reboot several times through all this. Just did now too. I did see an option to preference wifi calling over phone service. I did that and still it goes to stepping through to options in the phone service when I try to make a call.
You could try switching to airplane mode and then enable wifi only. Keep airplane mode, don't switch it off. Try calling then. This forces Wifi calling.
Finally got the option and my phone working. You are not going to believe what the problem was. It ended up that the service, BTW the service is Net10 Wireless, anyways they had the old sim card number on my account and they were using the the old number! The directions on the new sim card sent, stated to put the new card in the phone and call the number provided, which I did. I gave them the new sim card number and I assumed everyone was working with the new sim card. After well over 6 hrs with "tech support", some with a roster clearly calling out in the background. At the end I was demanding upper management right when I contacted someone. Finally had this tech support go through all the records and she figured out the sim card number was screwed up with the parties.
I'm pissed, it shouldn't take over 6 hrs and 2 days to get this resolved. I pointed out that this was the stupidity of "tech support" that caused practically this whole delay and I would say this people started the whole thing! I called up to get wifi calling up and running. The "tech support" stated that I need a new sim card. Which was the start of this mess. More than 23 calls to them regarding this!
In the end, I put the old sim card in and everything works! Even wifi calling works!
Great!

Sure would like to learn and know how and why the sim card plays a roll when you are trying to get wifi calling working. In my simple world, it's a working unlocked phone, a wifi connection, and the software on your phone to get this working.
Holly crap! Been using wifi calling successfully for the last day. OK so now I want to go back to regular phone service with phone providers. And you would think you could follow the steps at #7 and stumble your way to getting regular phone service, right. Nope, following the steps laid out will not do the trick. Now I got to figure out how to do it.
Any help on this? The Mobile Network option in Network & Internet is grayed out. Also the + sign does nothing. Turning off Wi-Fi does nothing to.
(Hoping the Hotspot & tethering is easier than wifi calling. I'll be in trouble if it's not.)
i don't have wifi calling on this phone but do on my note 10 plus,is it just in usa?

All I had to do was enabling Wifi-Calling in my phone and call the phone company to enable Wifi-Calling.
As soon as I am out of reach of my Wifi, it switches automatically to GSM or LTE (my contract does not provide me with 5G).
In other words: No need to change any settings.
Same if I disable Wifi manually. The phone shows LTE the same second.
