Roaming on Wifi question - Samsung Galaxy Nexus

I've tried searching the web for an answer for this but i keep coming up with the GS3 wifi bug that has a different description.
What i want to know is if im still on roaming while on wifi. The "R" signal disappears whenever I connect to wifi.
Hope someone can let me know asap as im waiting for a very important call from overseas.

Assuming that the R you are refering to stands for data roaming, then no, you shouldn't be data roaming once you connect to wifi. As for signal roaming, for your reception for voice calls, then I wouldn't think toggling wifi would affect that, you will still be roaming.

Wifi Calling

Does the Wifi Calling app save more battery? I've noticed the network signal turns off when I enable Wifi Calling
Sent from my HTC Vision using XDA App
Yes, saves LOTS of battery. Big difference when wifi calling is on.

Expanding on OP:
Does WiFi automatically supersede data as well? And if so, is there battery saving in that case?

When you turn on WiFi, all data goes through WiFi assuming that there is a good signal on it (aka if WiFi is so bad there is no data throughput, the phone will turn mobile data back on). The phone will always choose WiFi and turn off mobile data. Some/most people say that this saves battery because the phone isn't always searching for mobile data. I'd say that this is more true if you're in a situation where there is poor/low 3G reception but good WiFi reception. I almost never use WiFi because I get full bars and good 3G speed at home. I see no reason to use WiFi in this situation as my phone isn't searching for better networks.
As far as WiFi Calling goes, in the settings of the app you can choose to have the phone "Prefer WiFi"/"Prefer Cellular"/"WiFi Only". Same thing here. If I use WiFi calling, I choose "Prefer WiFi" because if for some reason my WiFi goes down while I'm not using the phone I want the mobile network to come on so I can receive calls without having to toggle back. A situation I could see where "WiFi Only" would be applicable is if you're traveling and want to use WiFi for calls if you have a data-only prepay SIM, or if you're in an area with only Roaming coverage and you would want to just use WiFi to make calls.

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.

Better cell network mode management

The tmobile service in my area sucks and it will stay on 4g lte even when I have a very bad connection which drops calls and gives me really bad speeds. Is there an app that will automatically switch lte/gsm/wcdma when the signal is very low so I wont drop calls, waste battery and give me poor dl speeds? Or is there anything else that I can do? Maybe with tasker or a tweak. I would appreciate any type of solution. Thank you.
Is there any thing I can do about this?
On stock Rom go to settings>more networks>mobile networks>network mode.
Pick the one you want. Probably gsm/wcdma auto connect.

Thank you for your reply. I already know about that option. I still want to have access to lte when I have a decent connection. Is there an app or a tasker configuration that if the signal is below a certain level it will switch networks? Also, which network it used to make phone calls? I thought all of them but my friend said phone calls are made on 2g. Thank you!

Is this a problem near your home? Can you use wifi calling to help fix the dropped calls? Not sure about how to get the phone to switch from LTE to 4G when the connection is poor. I do it manually right now because my LTE has been acting a little wonky lately where it won't even connect to LTE and leaves my phone in network limbo unless I force it to use 4G. I'd like to see a solution to the LTE - 4G switching too.
Last i recall, there is no tasker or app capable of doing such a thing like switching network preferences. It goes against "policy" per say. But your friend is right about calls being made through 2g. That is how you are able to use data whilst on a phone call. The data is being used through 3G and up, while the call is being used on 2G. now i am not sure about T-Mobile's "HD Voice" calling, that is prolly LTE.
I myself have looked through every single API google has trying to write my own app to change the network preferences and could not find it. There may be an option through root though. Havent found it yet.
Correct.
Calls - 2G
Data - 3G+
TM HD - New LTE Network.

When connected to WiFi I loose my LTE singmal

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.

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.
sent from my sm-900t.
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.

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.

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

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.

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

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

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?
