I noticed there isn't an option like on the HTC devices that let you choose WIFI ONLY or MOBILE + WIFI. It appears they took that out completely on the Samsung Roms? Is there anyway to disable DATA all the time? I'm in a wifi access point 24/7 literally. Sorry folks, only thing im curious about.
I would like to know also. None of the apps I have tried have worked yet.

Did you try to remove AT&T APN in Settings? It will not be able to connect to 3G without APN.
If you do not want to lose your APN nsettings, create new one, dummy, without any real data inside, and make it default one. Same results.
Another thought, if you have your Wi-Fi turned on all the time, your 3G connection should be switched down automatically. At least it works like this on N1. I am just thinking of bying Captivate, if it will have good custom ROM with Froyo, not taking it with all AT&T bloatware on board and Android 2.1
in the market check out the apps APNdroid and quick settings. Both have toggles for data connection
You can also put it in airplane mode and them just turn wifi on.

Thanks dude I picked that up works Great on Captivate. I'd rather use something like that than enabling wifi 24/7 to eat more battery etc.
I've tried downloading a number of free apps (including APNdroid) to turn off mobile data on my Captivate, but none of them seems to work. All the widgets give the impression that it is off, but I can still open the browser and navigate to websites. Am I doing something wrong, or is it just not possible to fully disable mobile data access on a Captivate?
Yeah you're right
@alobotnad
Hey you're right, APNdroid does nothing it doesn't even shut down the 3G icon on my device now and yes it still connects either way like you said.
Apndroid works fine on my captivate!

You see the 2G icon when you run it?
On my Captivate APNdroid only partially works. Let me explain. If WiFi is on I can disconnect 3G using the APNdroid widget (then if I turn off WiFi and try to surf the web I can't.) However turning 3G back on is more complex. I can turn it back on using the widget if I m connect already to a WiFi network and it will turn 3G on when I turn off WiFi. HOWEVER you must be connected to a WiFi network to turn 3G back on not being connected to a network means the APNdroid button doesn't work. The only solution I found to turn on 3G if I wasn't connected to a WiFi network was to turn on 3G through the APNdroid widget and then restart the phone.
On the other hand I am currently using Juice Defender and their 3G WiFi widget works without having to jump through all those hoops.
@icedfire101
Thanks for the info. I downloaded the free version of JuiceDefender today and so far I am happy with the results.
Samsung Captivate 3G Toggle Solution
After all the digging and searching around, I found two apps that work perfectly on Samsung Captivate for toggling mobile data (3G)
- Juicedefender (it has a widget you can use to toggle 3G quickly)
- SMODA Widget (It doesnt have too many 5 star ratings but works fine on my samsung captivate).
My phone is rooted but I believe it is not a requirement of either of the above apps. Hope this info is useful for other captivate owners.
Most of the other APN / 3G toggle apps on the market try to put a suffix on the APN names in settings. On the samsung captivate this works only with a restart/reboot. Meaning if you disable 3G using the app it would put a suffix like 'disabled' or something to the APN name. But your phone still has the 3G connection using the original APN settings. Only after you restart the phone does it see the 'disabled' APN name and is not able to use and hence no 3G. Vice versa when you want to enable 3G back - needs restart.
I dont know what process the above 2 apps use but they work instantly on my samsung captivate. No need to restart or click a bunch of other settings. They work perfectly and as simple as it should be.
Concepts behind Reliable 3G Toggling on Captivate
First time poster, hope its not immediately dismissed as TLDR.
For the quick-and-dirty just read the “Reliable Data Disabling”.
I am an advocate for understanding concepts. Solutions, hacks and work-arounds have their place, but, if we can understand more about how and why those solutions work, we might be able to repurpose those ideas and use those ideas to make better applications.
Upload and Download of data coming from the cellular network (as opposed to wifi) is likely determined by which network adapter the network connections are making use of. This might be determined by the android sub-system, by looking at the details of currently open sockets; or by lower-level processes looking at the addresses associated with Rx/Tx data. There are several other ways this could be achieved, and I am sure there are countless people who know exactly how that little 3g icon gets on screen; I am merely laying the groundwork to point out that the Captivate (and possibly the Samsung ROM specifically) is apparently more adept at retaining these residual 3g connections than other Android ROMs.
Let’s assume background data opens a series of sockets to communicate with all of the servers that a person’s phone will sync with. By obfuscating the APN like APNDroid does, we are changing the source of the configuration settings, but connections which are "kept-alive" would not check for new settings. This is why those connections remain open after we activate APNDroid. From this idea we derive at least two strategies that work:
Reliable Data Disabling:
Once an APN obfuscator has effectively disabled 3g by spoofing APN information, you can follow up the data-shutdown with the one-two punch of either disabling the cellular radio, or by intelligently terminating connections that don’t match the current APN paradigm. My understanding is there are no apps that take advantage of the latter.
Disabling the radio: Those who have a shortcut-to-activity application, one might feel compelled to use the “Testing” activity to disable the cellular radio, but, the contents of Testing can be dangerous. It is possible to cause problems with your phone using the Phone Information section of "Testing".
The Captivate is nice and fast, enabling flight-mode and disabling it after 10 seconds terminates all residual data-connections 95% of the time.
1. Activate APNDroid (or other APN Obfusctor)
2. Activate Flight Mode (or disable cellular radio some other way)
3 Disable Flight Mode (or reactivate cellular radio)

In the past 2 weeks I have discovered that when I re-enable my data, the 3g icon comes back right away but my phone makes no attempt to create new connections using the restored settings. The only solution I have found (so far) is to reboot the phone which only works about half the time. I have not stepped through the problem with the android debugger.
Has anyone else noticed this?
i use smartbar , it turns on/off data and does much more.
Best way to turn off 3g data in samsung captivate
To disable data connection.
In phone menu type *#*#4636#*#*
a menu will appear. In that click "phone information".
click the option button (which is the bottom left button you have in phone).
In that go to "more" option.
inside that click "disable data connection".
Thats it 3g icon will not appear up there in phone. but you can use wi-fi.
To enable it .
do the same thing above . but at the final moment you will be shown a menu with option "enable data connection".
clicking it wont immediately enable data connection. you have to restart your phone.
If you dont want to restart your phone .
then go to settings->wireless and networks->mobile networks->access point names.
there should be apn called "ATT WAP".
Click the more option button at the bottom left and click "reset to default".
Thats it. Now your 3g icon will appear at the top (provided wi-fi is turned off).

Good post. You are correct that the captivate will indeed hold onto the valid connection even after modifying the APN. Flight mode toggling will sever the connection forcing it to use the modified settings which should prevent it from reconnecting to data.
The way I disabled my data connection before froyo (all hail froyo data power- button toggle) was to make a shortcut to my APNs and I made a "disabled" APN that was just called disabled. I would have to select it and then toggle flight mode to disable, but reconnecting was as simple and just selecting the real APN and it would immediately reconnect. Never had to restart phone to reconnect, except when using programs from the market.

So how well does this work?
I'm going to Europe tomorrow and I don't want to be eaten alive on roaming data.
Thanks,
Super
Quick Settings in market, works great on my captivate.

Depending on what countries you're visiting and for how long, you might consider getting a prepaid local SIM card from that country. I've done that in a couple of different countries and was able to get prepaid data deals for a $2-$3 a day. Will vary greatly depending on country and carrier. And, of course, your phone will have to be carrier-unlocked to use the SIM card.
I have the Wifi enabled on my Droid Charge so when I'm home it will use the Wifi. But when using the Wifi the 'mobile data' icon is still highlighted in the pull down tasks..
now is it trying to use BOTH the wifi AND the mobile data at the same time? I want to use ONLY wifi at home to help conserve battery usage.
then when I leave my house will it automatically turn wifi OFF and use only mobile data?
trying to keep the battery usuage as efficient as possible.
In theory thats how it's supposed to work.
hahahha in theory.. but does it actually do it?
and another thing.. in the Mobile Networks Settings.. under 'System Selection'.. you can choose either LTE Automatic or CDMA Mode... being I am ONLY in a 3g area and do NOT have 4g LTE in my area yet.. should I choose the setting for 'CDMA Mode' Will that save the battery? or does the phone try to switch from 4g to 3g...
Yes, that is how it works. If wifi is on, the phone will use wifi by default, regardless of what it is connected to for mobile data (4g, 3g, 1x). Check out http://myresolver.info from your browser to see your ip and dns server you're using.
Ok I've got a few questions about the different network types and battery usage.
As far as I know there are 4 different possible scenarios:
3G mode active
3G mode active and connected to mobile data (3G/H showing in notification bar)
2G mode active
2G mode active and connected to mobile data (E or G showing in notification bar)
Currently I have settings default with "Use only 2G networks" unchecked, and "data enabled" unchecked. I have tasker made to automatically turn mobile data on whenever I open any app that may require it, and then turn it off after the app closes, or I can switch it on from the status bar power control.
This is because I assumed having it constantly activated would consume more power. Is this true? does it consume more power having data enabled even when no traffic is going through? If this wasn't the case, I might as well leave it enabled. However with my current system I could still be saving power because if I leave data on, traffic WOULD periodically be used for automatic sync and apps randomly using network and stuff.
The other thing I was wondering about is if there was any major difference in power consumption between 2G and 3G network modes with no mobile data connected. if 2G uses much less power, I could have it set on 2G by default then use tasker to switch to 3G and activate mobile data when opening any internet requiring app. Are there any other advantages of having 3G active over 2G other than mobile data transfer speeds?
Thanks for any help!
Imho your settings are good. Mobile network is one of the battery killlers, so not using (or better using it when you really it), is very good. You are right, 3g has a higher speed on mobile network. Whereas the 2g-network has a much better network coverage. And the permament switch between 2g and 3g drains the battery very fast, too (happens e.g. when you travel).
To sum it up: Use 2g and mobile network off. If you need to use mobile network, turn 3g and mobile network on. Are you done, turn them off again and switch back to 2g.
When you say mobile network, do you mean when an active data connection is enabled?
Because just by the name 'Mobile network", you can be connected to a mobile network for calling and texting etc. without being connected to mobile internet/data.
Is there a difference in call quality between 3G and 2G networks?
Also when toggling between forced 2G only and 3G there seems to be an inactivity period where the reception icon at the top shows like 'disconnected' like it cuts all network communications, then shortly connects again to the specified network type. This delay might be annoying when trying to get internet fast on apps that need it... might not be worth the power saving, if it is only minimal power saving
battery
for the best battery duration, use GSM ONLY!
I know this is a stupid question, and I'm actually embarrassed that it's my first.. but, does 4G get turned off automatically when I connect to a WiFi network? I know it maintains a connection to the data network for other services, but what about 4G specifically?
I think I answered my own question.. In the Phone Status info page the "mobile network state" DOES toggle between connected/disconnected based on my wifi status.
Not fully, or servcies such as mms would not work. However you can enable this to happen through Juice Defender, and possibly other applications as well. I fully disable network data with wifi connected through juice defender, only drawback I see is unable to send/rec mms untill you disable wifi, allowing the network connection to estblish itself again.
edit: This is only for the data network portion, voice services can and will still carry over the 4g conenction which is just enhanced 3g
Does it go to a state that uses less power than the "usual" network mode? I'm looking for ways to conserve power while maintaining full functionality. Using Llama and JuiceDefender right now also.
Juice Defender can disable the data portion of the network which saves battery when connected with wifi. In the on the "About" screen in Juice Defender scroll down, there will be an option that says "disable on wifi" under which you can select to disable the network data
Hi there!
I've some problems with my G-Nexus 5, as wroten in title,
the Wi-Fi and the 3g connection disconnects me during utilizing it,
if i look on the icons of wi-fi or 3g i can see that i'm not receiving any data and i cant continue to surf in web or by enjoying a game online.
So the question is its a hardware or a software problem, and if another one had the same problem.
So noone had this issue?
Sounds like hardware if this happens both to 3G and WIFI.
How do you fix it? Toggle Wifi? Airplane mode? Restart phone?
After a bit it begins to surf something like 5-10 seconds
I get the same problem on my 3G, it doesn't happen while I'm on WiFi. I have to disable/enable data or airplane mode on/off to get this working again. Also I have noticed that when signal changes from 3G to EDGE and then back to 3G I don't have data working. Need to to the same trick to have that back. It's annoying and you don't know when it working or not unless you check your phone....and lose notification from Facebook Messenger or Whatsapp which i use a lot.
I wrote to google lets see what do they say....
I got realy bored about thia issue.
I would verify that your apn settings are correct. Either call your carrier or maybe google your ("carrier name" apn settings). Also... Settings/Wireless & networks/More/Mobile networks/Preferred network type, is correct. I do know that in my case as far as wifi I get better results (quicker to connect) if the "Advanced " settings for "WiFi frequency band" is set to 2.4 GHz only. Default is Auto. Worth a shot.
