[Q] T-Mobile WiFI Calling unreliable - One (M7) Q&A, Help & Troubleshooting

Hi all,
has anyone else seen an issue with T-Mobile WiFi calling being unreliable? Its enabled and the icon in status bar present, but calls immediately go to voice mail. As soon as I disable WiFi calling and it switches back to cell network, calls work fine. Switch WiFi calling back on and it either works again or doesn't , its hit or miss. When I place a call during this time it just immediately drops. Since its so unreliable, I just turned it off completely, but I am curious if others have the same issue.
I am on ARHD 9.0 , but same issue was also on 8.1. I have not been on stock ROM since I got the phone.
Thanks

No 2G/3G while on calls...

I've noticed recently that I can't seem to access 2G/3G while on calls. I remember being able to do this with unrooted phone. Is there a feature or service I need to disable for this to work? I have wifi, gps, bluetooth all on at once, most of the time. Any advice would be greatly appreciated. Thanks!

Never ever seen edge/3g on my mytouch or my old g1 my g1 wasnt ever rooted the mytouch is and like I said I've never seen the data icon on while in a call are 100% certain that it used to be on?
I have 2/3g while on calls on my rooted g1. I think the issue is if you're on call, and hit a blind spot where you get disconnected from your data connection but not voice (this happens to be often). It will not reconnect the data connect edge or 3g until I end the voice call. I also get into this problem if i'm connected on wifi while i'm on call and leaves the wifi area, it'll not connect to 2/3 g until i end the voice connection.
you cannot use 2g + voice at the same time. only 3g

Tmobile wifi calling issues when in airplane mode and on Delta flights with gogo

I recently purchased a brand new XT1103 64gb N6 and was hopeful to make this my daily driver, but having nothing but issues with this phone ever since I've started using it...in fact, it has been so horrible I went back to the LG G4 that I was using before the N6...my issues:
#1. Wifi calling - I have gotten this feature to work at home, but it won't work if I put the phone in airplane mode and connect to a wifi network. For example, on Delta flights that have internet they offer free tmobile texting...by following the directions and prompts, it says that I'm connected, but when I try to send a text it tells me to enable cellular network. On my LG G4, if I do the same procedure, it enables the wifi calling feature and displays the wifi calling icon and I'm able to send/receive texts. On the N6, this feature does not work. I have yet to see any discussion on XDA about using the N6 to text inflight on Delta flights. In addition, I was recently in Paris and tried to enable a wifi call and it gave me the same error...."please enable cellular network to make a call"...when I take the phone out of airplane mode and enable wifi calling (when connected to the hotel wifi), it thinks for a period of time then will allow a wifi call, but only if the cellular network is enabled...never in airplane mode with just wifi enabled. Is there something that is wrong with the N6 in regards to wifi calling? On my LG G4, if I put my phone in airplane mode and turn on the wifi, it will enable wifi calling if I connect to a wireless network. Overseas it's imperative that I'm using a wifi call since TMO charges 20 cents/min on the cell network, but having to enable the cellular network forces me to initiate a call before I see that it's making a wifi call. I am not happy about the wifi calling implementation on the N6 and wish it was more like every other TMO phone I have used in the past...
#2. Signal quality and battery life - as noted in many posts, the signal is horrible and continually bounces around. I've followed several recommendations and have done the following when I received the phone - opened the box, flashed TMO 5.1.1 rom and rebooted with my TMO sim...phone did several updates, then updated to Marshmallow...signal was extremely weak anywhere I used the phone (I live in central Iowa and they only have HSPA+) TMO has not turned on LTE in my area of Iowa...I went to Chicago and experienced the same issues...fast battery drain and poor signal....I flashed Pure Nexus 6.0 and TMO 5.1.1 radio and experienced the same issues so instead of getting a headache messing with the phone, I just went to a local tmo store and got a new sim chip for my LG G4 and have been using it without issue for the last couple of days...It worked much better in Paris and maintained a better cell signal in Paris and I was able to make several wifi calls in airplane mode at the hotel there...
Can anyone share their thoughts and help me improve my experience with this phone? I really like the camera, screen, and feel of the N6, but I can't have a phone with poor signal, poor battery, and faulty wifi calling. Thanks in advance. Nick
wifi calling has never worked for me in airplane mode.. is it supposed to, i dont think so? and it sounds like you live in a small city or in the country? it sounds like it when youre talking about your signal. i live in nyc, and am on tmobile, and i am always connected to lte. my signal never changes, except on one spot on a highway near the ocean. other than that, my signal is perfect. anyways, you can flash and try different n6 radios. some work better for some and worse for others. and you dont need root to flash radios, but you do need to use fastboot.

I had the same issue using GoGo on the first flight.
At home, make a few calls when connected to WiFi. In settings/More, Switch from WiFi preferred to Cellular preferred, and go back to home (clicking ok as needed). Then, switch back to Wi-Fi preferred, (toggle the on/off slider at the top as well). Make a call again while connected to WiFi (make sure it shows WiFi calling).
Now, on your next flight, (in airplane mode, enable WiFi) connect to the gogo internet (use the initial splash page to select T-Mo texting/WiFi, captcha etc). Then, try texting - it should work. (it did for me)
I haven't tried WiFi calling from overseas, so can't comment - but I know I'd just use hangouts (or skype) to call.
I'll give that a try when I get home from my trip...I did try making a few wifi calls at home, but I didn't cycle the wifi calling feature...I will roll back the update to the stock TMO 5.1.1 and see how it works...
Quick question, is there a way to not install the 6.0 OTA from tmo? I'm guessing that I can just ignore it...N

Signal issues?

Is anyone having signal issues with the axon pro? My phone keeps going in and out of signal, and while my status bar says that I have "no service" I will have full bars, but only when connected to WiFi. When not connected to WiFi, all the bars are lost.
Is anyone else experiencing these signal issues or bug of this sort? Just trying to determine the root of the problem.

When did you start having problems? After the latest update?
I think it is a problem with the Wifi calling feature. After trying wifi calling and having problems (the other person couldn't hear me), I decided to turn it off.
After turning it off I started having crazy issues - the wifi calling would turn on even though I had turned it off. After turning off wifi completely, data wouldn't work so I rebooted the phone. After rebooting the phone, I couldn't get a signal at all. I tried rebooting the phone multiple times but the signal wouldn't come back. I switched SIMs and it still wouldn't work. At this point I was thinking there was a hardware problem with the phone so I was considering calling ZTE to get a new one. But I tried one last thing - I turned wifi back on and made a wifi call - the signal came back! So it is a software problem.
So I turned on wifi calling again but configured for "cellular preferred". It seemed to work well for a while, but then a few days later went crazy notifying me every few seconds that wifi calling was turning on/turning off.
To keep the phone stable I have now unfortunately had to setup the phone with "Wifi Calling Preferred". Thankfully soon after I did this I started getting error "REG09: Missing 911 address" so it doesn't try to use wifi calling anymore.
No point calling ZTE support because their phone support is appallingly bad. They won't understand the issue, they won't give me a ticket number. All they will say is either "reset the phone" or try to send me a new phone which will just make me lose time and lose data. They had a website where you could raise tickets for a little while...but it looks like it has been blocked now as it could have been too useful .

Trying posting to their Twitter account and report the issue, that is how i got their attention. Also when you call them (here in the USA) tell them that you have already done a reset on your phone and that did not resolve the issue!!!

I got some signal issues too I only get 2 to 3 tower usually but at time its completely dead and until I reboot my phone signal doesn't Pop up ...and at times even though I have like 2 signal tower it shows emergency calls oly...I don't use WiFi calling as am on straight talk.but the WiFi calling feature suddenly pops up in the notification bar giving an error message u can't swipe that off the notification bar too u gotta go to MORE in settings and switch on and switch off the WiFi calling feature to remove the error msg from the notification bar .
Signal keeps fluctuating call clarity is a lil bit poor comparing it to my old lg g2 . macro focus doesn't work at all u can't focus a thing that's really close in auto. I dono what to do with this phone.it just doesn't satisfy the basic need of a phone voice calls and message(messages take a long time to send ).

Again, not worth my breath. If you check the new thread someone called up ZTE about the issue and they blamed it on T-Mobile (which is complete and utter BS). When I called about the camera issues they tried to blame it on Google. Why waste my time to be told lies? The support is completely s***.

Well hopefully ZTE will come out with a fix really soon, I don't think that they want to lose the users they have.......
Loss of at&t signal
In one location that I frequent I always sit there without a cellular signal while people around me are using their cell phones
LTE signal strength sporadic
My Pro shows a few bars for a couple seconds,then NO SIGNAL for a few seconds. ZTE is not fixing this problem? It has been going on since January. Now is September.
For those with this issue, does a factory reset change this behavior, or at least the frequency of it?

Wifi calling icon missing on phone screen

I ended up going back to stock and taking the updates. The lack of development for the Verizon S6E basically did me in. :crying: I activated the advanced calling and the wifi calling option and I took a call and noticed the icon in the top left of the phone screen. After that call, when I am connected to wifi and making a call the icon has disappeared. I have performed a cache wipe and did a factory reset to no avail. I also tried to toggle the wifi calling feature on and off and I still do not see the icon. Anyone with a similar issue or that can help? Thanks!
If I remember right, the WiFi calling will only work as needed. So I don't think it will always be on.
I may be wrong though.
Thanks, I was wondering whether it determines which route will result in better connectivity. If anyone else has an idea about this I'd be happy to hear!
Yeah it only uses wifi if you have very low signal and strong wifi, or no signal and wifi.
Thanks, I figured it is operational by just going to airplane mode and switching on wifi. Icon came back and calls successful over wifi. Much thanks.

wifi Calling problems.... (help? pls?)

First off, I can make outgoing calls 100% of the time, and never have any problem except a split-second delay (as expected with VOIP)
Receiving calls though......
First, wifi calling randomly turns off, with a note I find later about "wifi calling is not available at this location" ---- yes, I have poor reception, and I know wifi calling requires an always-active GPS signal so rain or clouds can kill it --- but it never turns back on once the storm/cloud/whatever is gone, it stays turned off until I manually turn it back on.
Second, even when it is turned on, I will randomly get no notification - no ring, no vibrate, the screen stays black, and no "miss call" notification, I just get told later that someone tried to call me and it went straight to voicemail.
Third, when it does register an incoming call, I will swipe to answer and the phone app will... kinda half-freeze... it acts like it's trying to answer the call, where the red end button appears, but all the other buttons are greyed out except message. It's in a strange limbo-like state of being answered and not... when this happens usually the other party will connect and can hear me, but whatever they say never reaches me.
Fourth, I answer the call, everything seems fine, I say hello and just hear my own voice echoing, and even though I answered the call, they never connect and end up on voicemail.
I know that WiFi calling is a "new technology" (even if we've been using VOIP for years....) and Sprint hasn't "ironed out the bugs" yet, but is there anything I can do to improve it?
I have tried doing a hard reset on the phone, updating PRL/settings/OS, changing the phone data mode from LTE to CDMA, sprint tech changed out my SIM card for a new one, airplane mode (which doesn't work because it turns off GPS)... none of it works and I still miss a good 60%+ of my calls... any other suggestions?

do u have a vpn active?
plus i dont think GPS has anything to do with "WIFI" calling.
as long as wifi is connected to a proper wifi network, that should be all you need.( other than if a VPN is activated or wifi network is congested/ to many AP ssids with overlapping channels, then it should work fine.)
I did before the hard reset (one-dot), I dont now. so it didn't seem to matter...

Oh sprint. I always had network connectivity issues with them. I wouldn't be surprised if this is something that is wrong on sprints end

You have to have an active GPS signal for "e911 services" --- yes the app claims you can set your location manually, but doing so does nothing and as soon as my phone loses cell/GPS reception, wifi calling goes off and will NOT come back on till reception is restored (also I've used two of Sprints Femtocells and both of them required an active GPS for e911 so....)

yeah.... since about the start of this year my LTE speeds have gone down (though only in actual use! --- run speedtest and magically I have like 50mbps, even though I can't watch youtube even at 144p without it buffering and asking my phone "Alexa Next Track" returns an error about connectivity) Also my reception in my home has gotten worse in the last couple months --- for the last 17.5 years I've been able to make/receive calls on sprint over normal cellular without issue as long as it wasn't raining (yes, I've been with Sprint for almost long enough to raise a child.... they started out as the best carrier in my area, believe it or not), but now even though my phone reports 2 bars (out of like 8 or 10), I recieve almost no calls, and drop outgoing ones very frequently unless I switch to WiFi Calling.
So... yeah... I figured it was actually bad implementation on either Samsung or Sprint's part, but I was hoping there was something I could do to improve it....

Switch telco's... Sprint dropped the ball. They invested in. Winax , then LTE took off. They've been behind ever since
