I have had a crazy time both with wifi calling remaining connected (suffered sudden drops), and further SMS over wifi seemed spotty at best.
Part of this was caused by either a bad SIM card, or deletions of stock apps and/or services...which now have been fixed.
At the moment everything is working fine. Don't know if this will affect anyone, but I thought I would just add to the library of knowledge.
First, once I got wifi-calling working (meaning the status bar icon was no longer red), I started to read the log files and realized that every time the wifi was reset, wifi calling would not consistently restart.
What I have realized is that wifi-calling and SMS are dependent on TMOs mobile network via wifi. However, any internet connection is simply that...and any apps you have like FB or Google Voice will work with that wifi internet connection. Conversely,the TMO wifi-calling service/app either connects on a different layer (such as the IP layer) or uses some unusual node-based connection to traverse the 802.11 frequency, over your ISP's and other networks to arrive at the TMO servers which then are linked into the mobile network. You can see this by downloading an app that triangulates and provides tower locations nearby or gives you other mobile network data (i.e., CID, etc)... That data is either not decipherable by the app trying to get this data, or one gets unusual info when compared to non-wifi calling. Bottom line is that there are two separate signals being carried by the wifi: "data" and "mobile wifi calling" and they are completely different.
Another example of proof: if you are having difficulty with SMS using your wifi internet connection, try sending the SMS via Google Voice. If you have an internet connection, it will go through immediately. But regular SMS has problems if wifi-calling is not working correctly.
And one of the biggest culprits of this is wifi fixer or other similar wifi connection apps. Although it's only a guess, the "scan" these apps do are likely a simple ping to determine status of the DATA connection.
I shut off wifi fixer (but left it as a widget to use as needed), and I have perfect wifi calling and SMS.
Whatever criteria wifi fixer apps use when deciding to reset or reassociate the wifi connection is not reflective of the integrity of your connection using wifi calling. In fact wifi calling may partially interfere with your data connection which will typically trigger a reset by wifi fixer.
From now on, if I am planning on simply surfing the web and my wifi signal is less than optimum, I will turn on wifi fixer. Otherwise it just tears down wifi calling connection.
Hope this is of use.

Thanks for sharing your experience. I have an issue where over time Wifi calling disconnects even though wifi is still working. I have to re-toggle wifi to get Wifi calling back. It's very annoying.
Talk to NRGZ28... I think Energy ROM had a fix for that I'm the Amaze 4G Energy ROM

Although there have been occasional exceptions, it's unusual for a wifi call on my H1s to last longer than about a minute before dropping off/disconnecting. When this happens, the call time counter changes back to say "Dialing." Of course, there is no dialing, just dead silence. There are no other signs of a problem, no error messages, no indicator icons, etc. On the same wifi network I can make long uninterrupted calls with our older MyTouch 4G - no issues at all with wifi calling.
I'm running unrooted, locked, stock ROM (for now). I don't think I've removed any apps and I think the only wifi-related app I've used is Wifi Analyzer. Could you offer suggests on how to debug this? The firmware update didn't give any improvements. Should I ask Tmo to provide a new SIM card?
Thanks -

Well the first thing I would suggest is a factory reset. This being the most simple option given your phone is not rooted and on stock. The strange part of this is the "Dialing" instead of the normal keypad (which typically reverts when a call is disconnected).
As far as a SIM card, do you ever get any SIM card errors? Like "ER05" or "REV99"?
These are typically the errors of faulty cards or a bad wifi signal. Check out an app called Network Signal Info....it will tell you the strength of the wifi signal compared to the mobile network (although its not always reliable).
Let me know what a factory reset does. All of your apps will be restored by google (and their are apps to modify this restore as well).

Didn't reset yet, want to test a little more.
I've never gotten a SIM card error. The unexpected "Dialing" with the End Call button still showing is the only indication something is off.
Tonight I ran a few tests calling between our 2 Android phones in the same room, same wifi. 3 calls 1S to MT4G: 2 were perfect and lasted several minutes, while the middle call disconnected after less than a minute. 3 calls MT4G to 1S: all 3 went directly to voicemail, the 1S didn't even ring. Now I recall that's been a complaint before - that calls to me go straight to voicemail when I've been on wifi calling.

Are you sure wifi-calling is on? Do you have the blue icon in the status bar?
Sometimes this isn't on, even though wifi is on and you are making a call.. Not sure if that is intentional or not.
Just in case... The switch is in settings> more (under wireless and network buttons)

Yep, it's on.
Just to be clear, the H1S has received calls when wifi calling is on, it's just sometimes that they go directly to vm. For example, as I'm typing the phone just received a wifi call and is handling it fine, hasn't dropped after 3 minutes.
NO CONSISTENCY, BUT USUALLY DOESN'T WORK.
A factory reset did not fix the problem.
So, whenever I made a call on my N5, the Wifi gets turned off and it switches into 3G/HSPA+ mode (no LTE). When I end the call, it will connect to LTE and then enable Wireless again and connect like normal. This is on T-Mobile if that means anything.
Is this suppose to happen? Is there a way to prevent it from disabling Wifi during a call?
EDIT: The issue was with Tasker, since I use Cell Towers to tigger Wifi, and I guess calls uses different towers.
Anything? Even when receiving a call, before the call actually "comes through" the Wifi will be turned off; THEN the call comes through.
I just tried calling my ATT phone in a good LTE area with good WIFI. It did not drop wifi. I'm stock non-rooted 4.4.2.
There is a setting in the wifi page which prevents the phone from connecting to poor wifi. Is it possible that you're in a borderline poor wifi area and when a call is received your wifi drops just below that threshold and phone then falls back on 3G/LTE ? I noticed my phone at home when I go far from my AP I get 1 bar on the wifi but the phone says it is connected. But then wehn I try to access a web page, the phone would drop wifi and connect to 3G. I don't have LTE at home so I can't say if it would've connected to LTE straight away after wifi drop off
I have recently switched from Straight Talk to an AT&T 10 GB Mobile Share Plan. Since then my mobile data will randomly be turned off when i'm connected to wifi. It wont turn back on when i disconnect, nor when my device receives (or attempts to receive) an MMS message. Is there some setting i may have accidentally accessed since the activation? I don't have any programs that are capable of changing my device status like that (nor is my phone rooted).
Dont get me wrong, i'm glad something is trying to help me conserve battery haha, but it does get annoying since i only notice it when i get a notification that my device is unable to send/receive a picture message, or that i have no data once i leave the wifi network.
Its just weird since it has only started happening since switching to AT&T Postpaid.

Which ROM are you running? That is strange. It could be something with the APN as well. Are you on LTE or stuck on 3g? Maybe your phone is stuck in one and tries to switch from LTE to H or vice versa? I know when my phone chooses H instead of LTE (I use Cricket, but same towers) it takes quite a few seconds to get a data connection to load, but LTE is pretty quick to load.
It doesn't actually save battery to have data off when using WiFi since that is already happening behind the scenes. Not sure why yours is toggling the setting on its own but perhaps a factory reset would fix it.

Everything is stock. I had a APN automatically assigned from AT&T that caused me to constantly switch from HSPA+ to LTE. I found a better one online and now get LTE most of the time. I never really gets "stuck".Its not that the data isn't loading, its that it is literally set to "mobile data off" on my device, and i have to manually turn it back on in the settings. I wasn't aware an APN setting could change other settings on a phone?

it could be an app doing it, and you not knowing that it can.
My Nexus 5 is running Android 5.0.1 (Lollipop). Unlocked, not rooted. My carrier is Cricket. Here is what happens:
1. If the phone is connected to a WiFi network, I am unable to send text messages. The message will attempt sending for a while and then basically timeout. The app will report that the send failed. This will happen no matter what application I use (Hangouts, Google Messenger, chompSMS...). If I'm on the cellular network, texts send find. EDIT: Actually I'm seeing that's not actually true. Even when I'm on LTE, there's no guarantee messages will send. I can't actually detect a pattern here.
2. I am unable to switch from WiFi to cellular data by turning WiFi off. If I'm on WiFi and I disable Wifi in the Settings panel, the cellular indicator will change to show 2 or 3 bars of service with an exclamation point (!), seemingly indicating that I'm either not on the network or that I don't have data. If I reboot the phone I'll have full LTE.
I first started noticing the issues with text messaging back when I was running CM11 nightlies. Everything was fine and then a few weeks ago it started happening. I figured something had gotten messed up in those builds so I flashed to stock Lollipop but the problem persisted. I flashed to 5.0.1 and the problem remains. I also tried switching carriers from Cricket to T-Mobile, but T-Mobile service was so bad in my area that I had to switch back the next day; I didn't really get a chance to put it through its paces.
I know this is a weird one, so any ideas would be greatly appreciated. Thanks!
Hello, I am traveling internationally and have decided to use Wifi Calling to avoid getting charged for international calls.
I turned on wifi calling in the settings and went through the automated setup, and in settings it shows that wifi calling is on, however the wifi calling symbol in the top notification/pull down bar shows that wifi calling is off.
Obviously this makes things very confusing, and I don't know how to tell if calls being made are being made on wifi or if I am being charged per minute on the calls that I make?
Thank you for any help you can provide.
Notes: so far I have restarted the phone, used Sprint's reset to factory settings, updated PRL and Profile multiple times, however the symbol still shows that wifi calling is off while settings state wifi calling is on.
You'll get a little telephone icon in the bar across the top of the screen to the right hand side. When you see that, wifi calling is active and calls are going through that.
The thing with wifi calling is that it can be enabled, but it'll only fully turn on when signal drops below a set point. On earlier firmwares you could just go into airplane mode and enable wifi to force it over, but the latest firmware broke that workaround.
