When connected to WiFi I loose my LTE singmal - T-Mobile Samsung Galaxy Note 3

I have the Note 3. And everytime I connect to WiFi my cell signal goes from full LTE signal to nothing. If I turn the WiFi off my cell signal comes back.
I have WiFi calling turned off - Can someone please help me with this.
Thanks

Some phones do this and some do not. Mine did it on stock but when I flashed Jedi it no longer did that.

You can install the X posed framework with Wanamaker module and enable the 4G let icon all the time. That's what I do.

I would have to assume the radio goes into a lower power mode when WiFi is on. Do you really need your radio to tx/Rx full blast when on WiFi? Just because no bars are showing does not mean you don't have signal. I have wondered about this myself, because often this phone and others have exhibited the same behavior. Checking your signal manually always assures me that my radio hasn't shutdown. You don't need LTE anyways as there is not voice over LTE and I would rather have it downgrade to umts which I am sure it does. I do wish there was an option to over ride this for those rare moments you are expecting an important phone call but at the same time I am not that insecure nor do I let technology rule my mindset like that.

Forgot to add that when you do not have any signal you get the no signal circle which is rare when I am in a place I know I have good signal.. And when you see no signal in a place you think you should have full signal often times there are the other variables to consider.

I had the same problem and people made fun of me on here and said I didn't set my wifi calling preferences properly. Well, I did, and I'm sure you did too. The only thing that fixed it for me was flashing a custom rom. Both custom roms I've tried fixed it (MyRom and Wicked). Bug in the T-Mobile Rom if you ask me...

I'm on Tmobile and I'm having the same problem you have. I lose 4G LTE when my wifi is on. Wifi calling is off because of the caller id issue with oli or ;63, but that still occurs even with wifi and wifi calling off. It's hard for me to make a call on wifi since it will keep trying to redial with no reception. I always have to turn off wifi just to get my bars back and go on 4G to make a phone call.
It's pretty irritating if you ask me; hope either Samsung or Tmobile will make a software update asap.

Why do you want LTE on if WiFi is on.
When both networks are enabled then you are attached to two IP networks.
How are you going to make your IP traffic route if it is attached to two different networks?
I'm not saying it can't be done, I'm just saying that is the way it would be designed to work I would think.
There are definitely tools out there that show that they are not both active at the same time

I'm going to interject on this subject because it is annoying as hell. First of all I have the same problem, but when I'm connected to wifi, my cell signal drops to nothing and if I'm on a call I hear nothing but choppy voices and the calls always drop within 2 minutes. It may put the cell radio into a low power status but it also makes making or receiving calls unbearable or even impossible on wifi. I use a data on off widget and when I'm not using my phone I turn the data off, so this is not remotely an issue with me. My ability to talk on the phone is a huge issue and cell signal drop for me has caused me to never connect to wifi on my G-note3.

Sounds like the WiFi calling bug. My cell signal is terrible at my apartment on WiFi so I have low signal issues regardless. I have no problems in other places when connected to WiFi and making phone calls. I am on at&t though and do not use WiFi calling.

I had the same issue with my first note 3. I went back to tmo and argued It the no signal issue. It showed no signal when wifi was on but the cell was preferred over wifi calling. Turned off wifi signal, on no signal. Then after a few minutes the bars appeared back with wifi on. The manager came and told me that's normal for the bars to disappear. I said No Way Because they were there yesterday. But she said it's normal with wifi on I said I don't use wifi calling be I have good signal in house, But Need It on for browsing. She that's how it is I said bs, so I looking at my phone and I see no signal bars unless I turn off wifi or use wifi calling. Don't think so. And they only way I can check for signal is when I'm on wifi is to call.. No way. She said it's not a phone issue but a tech issue. I said it's the phone why was it on for the last 13 days ago now gone with wifi on. Finally she said she would exchange it. All this bs and she is my friend too. Now my phone doesn't have the issue but has rebooted by itself once again. I knew it was coming because the phone just froze on the flip app. I like Android and it's features, but damn I mess ios's stability.

Have you all checked your status when on wifi?

It's not about LTE and attempting to use data, it's that you lose all cellular coverage so you can't make calls. Even if I'm getting 100% of my data from my wifi, I still need to maintain a connection to the mobile tower to route calls (with wifi calling disabled, which I immediately do because it's unreliable and sucks).

Do you have a screen shot of it?
I assume when on Wifi and Wifi calling off, 4G LTE is not on because it's primarily on Wifi but you have signal bars.
With Wifi on and Wifi calling on, again the Wifi icon over takes the 4G logo. But the signal bars are down to zero because your using Wifi signal due to Wifi calling.

Just because it doesn't show signal bars doesn't mean you don't gave signal. Your dBm and asu trump bars.

I see his pic in the first post now.
I also see how I misread it.
There are 3 separate Radios at least that we are talking about here.
I think the OP should check this setting.
Settings >> Connections >> More Networks >> Mobile Networks >> Network Mode
Then tell us how it is set

Same issue here with Wi-Fi calling off and Wi-Fi on. I think it's just a bug with the signal meter.

Not sure what I am supposed to be looking at? The mobile network state? Mine also says disconneted when Wi Fi is on. Although my cell bars do not go down when I turn on Wifi is still says "disconnected". What does it mean? I tried calling my number it still receives calls.

Do you have any trouble making phone calls when you turn on wifi?
You may want to install "Network Signal Info" or some of the Network info tools and examine your signal levels with and without Wifi to see if these is any change.
"Network Signal Info" is a little buggy BTW

Airplane mode + WiFi calling

Where I live there is -50 bars of cell service, so when WiFi calling drops it starts searching and absolutely murders my battery life. Is there anyway to hack the system to allow WiFi calling while in airplane mode? I've heard certain phones can do it. Are there any devs on here that have the know how? I know we have some very talented people in the community so I'm hopeful. It seems like it should be pretty easy because while on WiFi calling the cell radios get shut off and WiFi works in airplane mode, so?
I'm just not convinced WiFi calling will ever be more reliable and only getting 9-12 hours on a charge really sucks! Anyways, here's to hoping for a fix!
If you go to WiFi Calling Settings -> Conection Preferences -> WiFi Only.
I think that would do the trick.

^ Tried it out of curiosity because it would be useful to me, but that does not work.
I wonder if it would work if you used a program like Tasker to cut only the cell radios without explicitly entering "airplane mode". Although I'm not 100% sure that is possible or if some other work-around is needed.
Maybe there's something that can be added to the csc feature.xml? Not sure what it'd be but theres already these listed:
<CscFeature_Settings_Airplane_Wifi_Dependency>false</CscFeature_Settings_Airplane_Wifi_Dependency>
CscFeature_Web_Bool_StartWIFISettingInAirplaneMode>false</CscFeature_Web_Bool_StartWIFISettingInAirplaneMode>
You could check other devicrs that have wifi calling and see if theirs is listed. This may not even work, but could be worth a look.

Also, there's an app in the store called Bobsled Calling (also a Bobsled Messaging app) listed under T-Mobile top picks. Don't know how good it really is, but I was thinking bout giving it a shot on my old phone that has no cellular service at all.
One of the only ones I've seen where the people you call don't also have to have the app.
Maybe it'll allow you wifi calls under airplane mode?

You can try going to your Phone app and typing in *#*#4636#*#* -> Device information and then hit the 'Turn off radio' button. I used it before when Hurricane Sandy knocked out the cell towers and I was left with just random WiFi hotspots, but this was back on ICS. Though I don't see why it shouldn't work with JB.
If the code doesn't work, go to the Play Store and download an app called 'Phone info' (Author: [email protected]). The app should take you to the Testing menu.
Instead of constantly typing all those numbers (*#*#4636#*#*), download the app, Phone Info in the Play Store and there you go....

That app doesn't work because when WiFi calling is working the radio is idle. Service menu is a no go.
Sorry I didn't post it as a Q but I didn't have a clear question. I wanted to discuss the topic. I thought about yet where to post it before I did, thanks.
WiFi calling with Cellular Radio turned off
I am trying to accomplish the same thing but was approaching it from a different angle. The service menu idea doesn't work.
We are both trying to accomplish the same thing. Use WiFi calling while having the Cellular radio turned off. Airplane mode turns off all radios and you can re-enable the WiFi radio. However the Galaxy S III will not allow a call to be made while the phone is in airplane mode. This is a low level system issue and not related to the dialer (I tired three different dialers).
Does any body know of a way to do this??? PLEASE??? I'm leaving for Brazil in 4 days for a month and I would like to be able to do this in Brazil.

According to Samsung & T-Mobile the only official way to turn of the cellular radio is to enable Airplane mode.
Here is the procedure that I tried:
Enable Airplane Mode
Turn on WiFi
Connect to a functioning WiFi hotspot
Enable WiFi Calling
Wait for the WiFi Calling Icon to appear in the status bar
Make a WiFi call
At this point the dialer sits at the dialing screen for more than 10 minutes (I bailed at 10 minutes). As soon as I abort the dialing attempt a dialog box pops up saying you cannot make a call while in Airplane mode.
Is there any way to completely disable the cellular radio without putting the phone in Airplane Mode?
Is there an app that will do this?
Is there a hidden that will do this?
Please don't use bandwidth by asking why I want to do this or suggesting that I use Skype or some other app. My goal is to be able to make and receive VOIP calls while the cellular radio is completely disabled.
Thank you for your help...

I think maybe the phone HAS to ping a cell tower in order to make WiFi calling work. For your purposes just set the WiFi calling connection preference to WiFi only.

I have zero reception at my house and wifi calling works.
Setting it to "WIFI only" doesn't allow it to work the way that's wanted - it just tells the phone to only make calls over WIFI - but that doesn't open up the ability to do so when the radios are off. From what is described I agree that this sounds like a conflict with the low-level integration.
Did anyone try that Bobsled app I mentioned earlier?
It claims that I could put it on a tablet or my old phone that has no sim/data, and it would work.
If it were to work is that something that could get you by for a while? I understand not wanting to go 3rd party, but it could be the only option for now. It is a tmobile app btw.

I meant for the guy going abroad. Although he needs to also make sure data roaming is off, I think.
Doc I did look but my problem is I want to use my tmo number. I have a house phone but it's really frustrating to tell people they have to try me at two different numbers. And not being able to text.

There's also a Bobsled messaging app. Pretty sure its the same deal and works via wifi.
Also, I could've sworn it said that you have the option of using your current cell number. Maybe I'm mixed up on it...
Anyway, its just a suggestion for looking at. I have no idea how good it really is... just don't have many other ideas for you guys at this point.
I wonder if there could be a build.prop value that would disable cellular only. Or set its scan frequency like you can do for wifi.

I have done some more research.
I was able to turn off just my cellular radio by using the phone info application to enter the service menu (Phone Info App->Device Information, scroll down and select Turn off radio).
With the cellular radio turned off I tried to enable Wifi Calling (Settings->More Settings->W-Fi Calling).
The phone says "enabling", turns on the cellular radio (without any messaging saying that it is doing this) and then says "Ready for Calls".
I also tried enabling WiFi Calling first and then turning off the cellular radio (using the method outlined above). But the cellular radio would not turn off as long as WiFi calling is enabled.
I don't know if this is a bug or a "feature" but for WiFi Calling to work on the T-Mobile SGH-T999 (4.0.4 Firmware) the cellular radio must be enabled. Though I'm sure T-Mobile has a reason for this the logic of it escapes me. WiFi calling should not need the cellular radio for any reason. I use Skype all the time and it doesn't need cellular service to operate on WiFi.
If anybody out there knows how I can make and receive phone calls using my regular cell phone number exclusively via WiFi (with the cellular radio disabled) please let me know. Many thanks to the person who figures this out
As long as you are connected to Wi-Fi, with Wi-Fi calling activated (blue icon showing), it should automatically disable the cellular radio. If you are connected to Wi-Fi, but no blue Wi-Fi calling icon, then it will turn on cell radio and start searching for towers.

Duh.. the reason to use it in airplane mode for me is that WiFi calling disconnects every few minutes and when the cell radio is searching since I have 0 coverage it absolutely kills my battery.

Sorry but you're not making any sense. You're complaining about your phone's search for cell towers killing your battery because your Wi-Fi calling keeps disconnecting? Let's say you find a way to disable your cell connection. Your Wi-Fi calling still keeps disconnecting and you still can't receive or place calls. What's the point? Longer lasting "iPod"? Maybe start looking for a way to fix your Wi-Fi calling problem would be a better solution, ie. Flashing a different ROM until you find something more stable. Duh!

These are the following options available (all of these options have the cellular radio enabled and working at all times):
1. Make calls using the cellular network only - WiFi Calling disabled.
2. Wi-Fi Preferred - Make calls using WiFi Calling if a valid WiFi network is available and connected. Cellular network calls are made when a WiFi network is not available.
2. WiFi Only - Makes only WiFi calls. Cellular calls are not made when a WiFi network is not available. Note: This does NOT disable the cellular radio.
3. Cellular Preferred - Makes cellular network calls are made if a cellular network is available. WiFi calls are made if a cellular network is not available and a WiFi network is available and connected.
When enabling WiFi Calling the cellular radio is briefly disabled and then re-enabled..

I've tried multiple ROMs and multiple routers so.....
My only "solution" would be to not use my phone at all at home and just turn it off. I'd rather have a longer lasting iPod than a paperweight.

When on Wifi, cell signal switches from 4G and I lose all bars

So when I'm on wifi in my house, my phone appears to switch to edge or something and I lose most connectivity (goes from 4 bars to none). Enough to initiate a call, but simple head turning will cause me to drop. If I turn off wifi, I get 4G back and full bars and no dropped calls.
Wifi calling is too inconsistent to rely on, and this basically makes my phone unusable. I don't want to keep wifi off, as it's a lot faster and I only get 2.5Gbs of high speed data to use a month.
I'm also in the middle of a major city with great coverage 4G coverage, as long as I'm not on wifi....

If you go into your wireless settings, you can uncheck Wifi Calling so that if you do connect to Wifi, you will retain your regular amount of calling bars.

I appreciate the response, but I've already had wifi calling off.. because that feature was basically useless (could not rely on it ever).
My wife Note3 got the same problem, set cellular network preferred and then turn off wi-fi calling. Lose all cell signal bars. When no cell signal, caller ID became funny, like 718-123-4567;oli=63 212-123-4567;oli=00, had no idea.
My own note3 had the same setting, but everything fine. full cell signal bar. Try to google it, no glue!!!
Then I returned my wife note3 and get another one, everything fine.
I had the same problem. When I was on wifi I had no signals. I got a new sim card and the problem is now gone.

Uhh... it certainly doesn't switch back to t-mobile without issue. I drop the call. I haven't had a single call work the entire time while leaving my wifi on in my home.
Clearly, when it's on wifi, even if you have wifi calling turned off, it switches to some other network specifications, which appear to barely work where I live. The problem likely lies in the fact that when you turn wifi calling off, it does not switch your cellular network preferences back to normal properly, Instead, when wifi calling is off and you're still on wifi, it just doesn't route things through wifi, but doesn't actually change your mobile network settings back properly.

well here's a question do you leave mobile data on even though you're connected to WiFi? As i have no problem because i have bars even when connected to WiFi because i leave mobile data on and have WiFi calling turned off. even if WiFi calling is turned off, and i turn WiFi off it switched to T-Mo network in seconds and i'm able to call someone so yeah no issue. you clearly have a problem with something or its the network where you live.
i'm not trying to be rude but it just doesn't make sense to me that you're having issues with something that shouldn't be a problem.

This doesn't actually work currently on the Note 3. there is a bug where any time you have wifi on the cellular entenna turns off regardless of the state of your wifi calling on a very large number of Note 3's. Lost Soul clearly hasn't been reading on the threads here. there are many on this topic. We get that you don't have the issue LostSoul, but that doesn't mean it isn't an issue.

Thanks Hughes,
I have found that when it enters that state, that if I go and turn wifi calling on and then set it to mobile-network preferred, it turns the cellular modem back on, at least for a little while. Can you point me in the direction of a more robust thread where others are discussing the issue?

I've flashed a rom as well and it appears as it might be fixed... hope so.. my phone is useless if it can't function as a phone while on wifi.
I had same issue. Called TMo and had them unregister my wifi calling, and got bars back immediately. I had wifi calling turned off, but it seemed to be the default regardless. I could only receive and make calls with wifi turned off...but it all works fine now.
That didn't work for me

I called Tmo four times and asked them to unregister wifi calling. They said that it wasn't even turned on for my account then that it doesn't matter what is or isn't turned on. The phone is going to run calls, text over whatever wireless connection it thinks is appropriate. When you have a strong wifi connection, it chooses that connection regardless of wifi calling being turned off or on. I set the wifi calling preference to cellular networks and it still does the same thing.
I'm pretty pissed off about it. Anyone fix this?
Not true. I shut off Wi-Fi calling on T-Mobiles site and bars came back. Had the exact same problem.

Just got a note 3 for tmo, currently my device is unrooted and fully stock. I noticed that my wifi being on, it works great but cell signal is near gone...sometimes even wont let a text get sent. as soon as i turn off wifi cell signal is perfect same as on my note 2 or that G2 i got rid of.
i noticed the following....
Wifi signal switching feature on or off, cell signal still is gone.
Wifi on, wifi calling on or off signal still suffers, in fact i even disabled wifi calling from the application manager for now. (never did like wifi calling)
Wifi on, make a phone call signal still stays low.
Wifi off, cell signal strong
Wifi off, make a call all is even better.
So, whats the deal? is there a fix? A search only came up with a thread about turning off the wifi switching thing in advanced features, but like i said it dont matter or work. any other search talks about wifi and it dropping and or about wifi calling dropping calls....
edit, i looked in the system setting, and noticed that the signal in my house right now says -90. turn wifi on, network says unknown from LTE, and sits at -90.
turn wifi off, network says LTE and signal still stayed at -90 (it did change a little but stayed at average of -90)
it seems as if the signal bars just dont show up with wifi on. like it cant walk and chew gum at the same time (cant show wifi bars and cellular signal bars at the same time)
what threw me off was when i couldnt send a text until i turned wifi off.
i also disabled wifi calling from my account level as well. didnt change anything.
do these phones need the sim that came in then box? my sim came from a note 2.
It is odd, but I have the same behavior. When I'm on WiFi, I have no bars for my mobile signal despite there being no change in the signal related parts of About Device->Status
So, no real answer, but you're not the only one seeing this.
Turn on Wi-Fi calling. Make a call to ur vm. End call. Go to setting click Wi-Fi calling and then connection preference. Then click prefer cell network. Wait 5 seconds then shut off Wi-Fi calling. Should be fixed
TWEAKED 2.0 NOTE 3
I have no idea why, but this worked. I already had the 'Prefer mobile network' option set and Wi-Fi calling disabled, but this little dance corrected the problem. Thanks for the tip!

amazing, i didnt make a call, all i did was turn wifi calling on, then off and all the sudden cell signal worked with wifi on. but for some reason, my phone app FC when i tried to look at the connection preferences. not that i care i dont use WIFI calling as it sounds like crap or is choppy for some reason. (well in the past it was) thanks! now i can actually use wifi!
I called someone the other day i had wifi on, and the person couldnt hear me half the time. next phone call was wifi off and everything worked perfectly. very odd bug, im shocked that it hasnt been corrected yet.

Only default text app (Hangouts or any from the Play Store can't) can send MMS and SMS through WIFI.

Mobile data sticks even on Wifi

I'm having this strange issue that I've never before seen on Android. Whenever I'm connected to Wifi, the phone seems to maintain a mobile data connection. Also, I'm on T-Mobile with wifi calling enabled, and it seems to stick to the cellular network even with wifi on. Am I the only one?
Ive got something similar, my battery stats show Wi-Fi is on even though its off. Rebooting the phone sorted it out.

Oh that makes sense. Thx

My M8 does this, so I would expect the M9 to do this as well. However the mobile data is not used; the icon for mobile data just stays up. It passes data on WiFi when a WiFi connection is available. The WiFi icon is the only one that comes and goes.
I have unlimited calling so I don't use the WiFi calling, can't comment on that.
My mobile radio stays active even while I'm on WiFi calling. Which, I'm pretty sure the mobile radio should completely turn off..
Mobile data icon stays on as well even without wifi calling, same as you.
I think the stickied mobile data icon is a non-issue, but the fact that it sticks to cellular network, pointlessly draining excess battery (especially in a region with poor network connectivity) when Wifi calling is enabled, is seriously annoying.

Both settings are unchecked, like in your screenshot.
Just got mine too.
Am noticing the same problem. Mobile data stays on.
Hopefully there is a fix coming out?
Figured it out (For T-Mobile WiFi calling variants only)
Go into WiFi Calling settings (there should be an icon in your status bar)
Select the bottom "Do not use Cellular". This will disable cellular when WiFi/WiFi calling is enabled.
Cellular was enabled for calling handoffs (when you leave a WiFi calling area, the call gets handoff'd to the network)

Nah. That solves nothing. I don't want to be disconnected when leaving Wi-Fi. I just want cellular to be off when in Wi-Fi range, which was automatically managed with the same setting on previous phones.

Correct, all that setting does is completely disable cellular. Even if you leave Wi-Fi, or disable it.
On all previous T-Mobile phones with Wi-Fi calling using "Wi-Fi preferred" it would completely disable the cellular radio.
Now, when I have poor signal but am using wifi calling, my phone is constantly searching for signal. Switching between 2g/4g/lte.
Yeah, you guys are correct.
Left home this morning, no Cellular.
Well, shoot...

Poor LTE signal, doesn't switch to CDMA, WiFi calling flakey

When I am home I have little or no LTE coverage, and even though in network its set to LTE and CDMA, it never seems to switch to CDMA even though I have like no LTE coverage at home. I never have more then 2 bars, usually I have 1 or no service at all.
And WiFi calling is unreliable as well. Often it says it's logged in but it doesn't work, it it fails to login and then apparently doesn't try to login again. If I turn WiFi on and off, the WiFi calling usually then logs in.
Anyhow, if I can't get the phone to automatically switch over to CDMA or if I can't get WiFi calling to work reliably, I'm going to cancel my sprint service since my phone isn't really usable at home. I don't want to put the phone into CDMA only since I would have to reboot the phone every time I go outside to get back on LTE
BTW, I get great LTE signal right outside my house.

staying on wifi doesn't really help me since wifi calling doesnt seem to be very reliable. Right now staying on lte seems like a better option since at least i can see when i have no signal. Wifi calling half the time says it's logged in, but it doesnt work.
you may need to get an airave since you aren't having service in the house. Just call up sprint and let them know what is going on and ask for one. Hope this helps!
I'm just worried the airwave well be as reliable as the wifi calling since it's essentially the same thing.
I wonder if there's something in android I can tweak that will make the phone jump to CDMA if the 4g signal it too weak.
I've noticed that if I have one bar and make a call, it almost always jumps to full bars as soon as I started the call. I'm guessing it's jumping over to CDMA. But why doesn't it do that when the phone is idle?

I believe that the bars you see before initiating a call are the data signal strength. When you press the call icon the phone Radio switches to cell 1x signal. which is usually pretty good in most urban areas and that is why you would see the signal bars jump to full strength.
My wife uses WiFi calling at home and it works very well. Maybe disconnect your phone from the router and do a restart/reset of your router. Then reconnect.

Why would it show that if the phone is on wifi though?

I've tried turning the wifi on and off on the phone. That will usually get it to work, but I have no way of knowing if it keeps working since as I said, it will sometimes say it's logged into the wifi calling but not work.
I tend to think it's not an issue with my router since every other online activity works great, including skype or streaming 4k videos on Netflix

The Wi-Fi icon is also a signal strength indicator. When on Wi-Fi the signal bars to the right are mobile data, then when you receive or make a call they switch to cell tower reception strength. When I'm on wifi and see only one signal bar next to it I know that I'm on LTE. if I see full signal bars and I'm not ona call, I know I'm on 3G. if I turn off wifi I will see either the LTE with 1 bar or 3G icon with full signal. this is at my house so its always the same and its a easy way to check how the signal strength indicators work on your phone. make sense?

I have two signal strength indicators on my phone. One for wifi, and one for call (or data). So i don't really understand how the wifi icon is also a signal strength indicator since there are two separate icons for that. Why would the phone show an indicator of the strength of data if I am on wifi and not using the data connection? On my phone (note 4, rooted but stock) i pretty much always have full wifi signal strength, but i have have zero bars/no service on the signal strength icon and when that happens, if anyone tries calling me, it never comes through. I don't have anything in the missed call log - just no call. Can't send a txt either.
The next time the phone drops to zero bars/no service and i happen to have someone else with a non-sprint phone, i'll try calling myself just to confirm the behavior.
Same for me. The signal and data quality is ****e compare to Note 3

So on the same network you had better signal strength with a note 3 vs a note 4?
