When I installed my ROM, and on first boot I was given an option for when to use data.
Wifi only, or WiFi and Mobile Networks.
Now, I am going on holiday in a week and wanted to switch it to WiFi only to avoid data roaming charges.
Can anyone help, I cannot find it in the settings.
Settings > wireless and networks > mobile network.

Obviously I looked there first. There doesn't seem to be a "WiFi Only" option.
If I just deselect Data Roaming, will that essentially do what I want?
Yes, just turn off mobile network and turn on WiFi.

In the widgets > settings widgets you can choose mobile network and wifi network (as well as gps and bluetooth) screen widgets so you can toggle them on and off.... when not wanting to use mobile data, its good to have those widgets on one of your screens (as the dashboard widgets are usually missing one or another of those 4 essentials)
saves time from going into the settings repeatedly just to turn something on or off.

It is stated in the setting that it enable/disable data packet usage over mobile network. It has absolutely nothing to do with your phone call whatsoever. What makes you think that way?
Just kidding. In extreme cases, to prevent data on moblie network, one uses firewall to block access to any applications that try to access it.

All you need to do is deselect Mobile Network. Even the description says its used to connect to the internet.
a question really easy
So when i am home i have my WiFi on, which means my 4g is off. Now when the WiFi is on, i can not receive or send pictures. Also cant use the web or do anything like that but just send and receive text/calls.. and reason to this? maybe i have certain settings on that i don't know about? If i remember right, my wifi worked properly a few days ago.. but i cant remember exaclty. Help please? Thanks
no one knows?
Power cycle your router?
I've been having a different wifi issue. at home I have only edge coverage but I have petty good cable internet so obviously I want to use my wifi but for some reason the phone connects to wifi yet still uses the mobile network unless I turn off mobile data. My wifi sleep policy is set to never btw. Any ideas?

Also if I turn off mobile data while connected to wifi then turn it on while still connected it stays on wifi fine. Its like the mobile radio is preventing the wifi connection from fully initializing or something
Same issue!

I am having the same issue. I have to go into airplane mode, then turn on wifi to actually be able to use it... otherwise seems to default to mobile radio...
I have the same issue..this is what i do to work around it though:
1. Go to Settings>Wireless and Networks>Mobile Networks
2. Uncheck packet data, and then check it again.
Once i do this, my wifi works again, let me know if it works for you.

Got this from the battery thread. This actually fixes the wifi issue on my SG2
The program is called Llama and can be downloaded from the market. I deleted all the default events and just added these 2. Hope this helps for all of you with this issue.

-- Add action: Toggle Mobile Data (off)
- Add another event called WiFi Disconnected
-- Add condition: WiFi Disconnected (any network)
-- Add action: WiFi Sleep Policy (sleeps when screen turns off)

Try freezing "my account". It toggles data even with WiFi is on. Try it and let me know.

Actually saw this tread and had Llama installed with these 2 profiles added and was till getting this issue... Going to try Freezing My Account to see if that helps... I know it helped with my wifi issues on my G2x.
Update: Nothing seems to work now. Can't have Wifi and cell radio on at the same time... can get calls but nothing else...
I've seen it occasionally as well. I haven't needed to reboot though. It usually recovers after I toggle WiFi on and off and mess with some other things.

Yes, either return or warranty exchange for a new one, I have not noticed this issue with my device at all.
I've been having the same issue and it definitely causes excessive battery drain. Sometimes toggling wifi off then on works. Other times it requires toggling mobile data off then on.
I had it happen just now and tried freezing 'my account' in titanium backup as suggested and my 4g indicator immediately turned off. Sweet! It seems that 'my account' is the culprit!
Edit: I really wish this topic wasn't merged...I think there were a couple 'wifi problem' threads talking about different issues. To clarify, my problem was that while on wifi my 4G indicator would sometimes turn on and consume more battery and (sometimes) force all data to use 4G instead of wifi. Really annoying!

[Q] WiFi not working properly? 3G/4G stays on
My mobile data doesn't always turn off when wifi is on. Any ideas?

What is the difference between LTE and Mobile Data?
Lte is a type of mobile data hspa+ is another type
Mobile data is data streaming over your carriers network. It what you use to browse the internet, check emails pretty much everything on your phone except calls and texts.
LTE is the speed of your mobile data connection, currently the fastest. There are different mobile data speeds, 2g/edge, 3g, 4g/lte.
Hopes this clears this up foe you.
Edit--> beaten to the punch lol
Thank you for the explanations. While I am at home or work I was trying to decide what items to turn off. I can turn off the GPS, LTE, & Mobile Data and use just use wi-fi.
I believe mobile data already turns off/disconnects when you are connected to wifi. If you go check your "about" screen while on wifi, it will show the mobile network at disconnected.

This ^^^^^
The difference is when your Wi-Fi signal depreciates (for whatever reason), if you still have Mobile Data enabled, your carrier's data will pick up right where Wi-Fi left off.

Yep you are correct. I turned on/off the wi-fi and the mobile network state turned on/off accordingly. Does turning off mobile data help extend the battery?

The reason I ask is because I am setting up some NFC tags and I wanted to know what services are OK to turn off.

Yes it does. WiFi uses less battery. Mobile data is right there with display for the two biggest battery consumers.

I noticed mine seeming to drop from wifi when the screen is off for a while, even though I have it set to leave wifi always on.
When I would turn the screen on, it would show LTE, then LTE and wifi, then just wifi and give me the message that it connected to wifi. I also noticed the icon for the preloaded AT&T Smart Wi-fi. My assumption is that this app is causing me to drop from wifi when it shouldn't be.
I disabled AT&T Smart Wi-Fi and haven't had the problem so far today.
Jrockttu, thanks for your suggestion, it was driving me nuts. I've just picked up my Note II yesterday and UNFORTUNATELY I enabled the AT&T Smart WiFi app (and then forgot about it, of course). After that I couldn't stay connected to WiFi, the WiFi radio kept cycling on and off, it was maddening. Luckily I found this post, and after disabling the stupid app, now I can stay connected to WiFi.
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.
