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.
I have a WP7 phone and I have access to wifi except while I'm on the road. The phone automatically connects to the wifi. I have noticed that the data usage is ALWAYS going through my T-mobile account rather than wifi. How can I make sure that the phone uses wifi whenever available, and T-mobile when there's no wifi connection?

It DOES switches to WiFi when available and automatically switches to data Connection when WiFi isn't available. I confirmed it few days ago by installing Counters app for my Lumia 710. It tells you your mobile data usage. It stopped when I connected to my home WiFi and Data Connection was still ON.

Maybe the Lumia is better built than my Samsung Focus. I swear the Focus cannot automatically do this. Maybe it's because it was made for AT&T and not T-mobile.
I recently bought a Moto G US GSM Unlocked and a Straight Talk Unlimited plan. I put Cyanogenmod 11 on the phone before installing the sim card, then installed the sim card and set everything up. I had to use the AT&T card for my area.
The problem I'm having is connecting to mobile data (HSDPA and HSDPA Plus). When I turn the phone on it takes several minutes for it to get a data connection. I have full bars (or some bars, depending on where I am) but no H or H+ icon, no internet connection. The same thing happens after turning off WiFi, it takes some time to get the data connection. Then after it does get the connection it cycles between H and H+ randomly.
I have researched the APN settings I should be using, and found a great thread on androidcentral with a bunch of people trying different settings. The settings I am using now let me send and receive texts and mms, and use internet. But it still takes a long time to connect when the phone first starts or I turn off WiFi.
Is this normal? If not, what could be causing this? It's frustrating because I plan on using WiFI almost exclusively while at home and turning if off when I leave. I don't really want to wait several minutes after leaving for the phone to get it's internet connection back.
Thanks
Need help guys. Hopefully this is okay since I'm using the S6 regular Dual-sim Philippines model. I'm using 2 sims (Globe and Sun network) and I always use my Globe network for mobile internet since it's faster. Now, when I use the LTE capable network for mobile internet for a couple of minutes (possibly hours as well), both of my sim cards would suddenly shut down (their mobile icon turns hollow, mobile internet disconnects. Sorry I can't provide the screenshot since i forgot while making this post). After a while, both networks will have their signal back and I can resume browsing again. This usually becomes a problem when i play online games since the game constantly checks for a working internet connection and it cuts me off the server if i'd lose my internet for a few seconds. What i've tried is that I'd turn off the other sim card (Sun sim card) but since I also use this sim for communicating with people, I can't turn the sim off permanently. Can someone please enlighten me on what to do or what might be the problem? Is this supposed to happen to the dual-sim variant of the S6? Hope you can help me out guys.. Sorry for the long post though.
TLDR: Using dual-sim variant of S6 (Philippines). Using two sim card networks (one for internet, one for texting/calling). When using mobile internet (LTE mode) for a couple of minutes or hours, both sim networks would suddenly shut down and I would lose my internet connection. Turning the non-internet network/sim off somehow fixes the issue but I need both networks on since people would call me at the non-internet network sometimes. Is this expected from a dual-sim variant or is there anything i could do to fix this. Thanks guys!
Is VoLTE activated?
Loving my Urbane 2nd Edition since I got it and upgraded to AW2.0. However, noticed that the watch doesnt "kick" into LTE mode as well as it should at times when I am out of range of my phone's BT or home WIFI. Works better when rebooted. Anyone else having a similar issue where the watch almost refuses to automatically switch to LTE without the phone BT or WIFI?
Mine had never got cellular connection worked, the LTE and wireless signal are showing, but the little cloud with slash is displaying too, never got real connection, no matter if the phone is on/off or in/out of range.
Since 2.0 only calls are available via LTE, but no data streaming
I tried several times with/without roaming, choosing carrier or auto, I can't receive data via the sim card of the watch. Can you please approve or i have a sim issue /watch issue?
If you're using an MVNO's SIM that requires special APN settings, it won't work. Forget about using FreedomPop or Straight Talk or such - it'll have to be the MNO's own brand or APN settings to work. There is no APN editor in Android Wear / WearOS.
