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,

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.
So I followed this guide (http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Rooting_the_G2) to root, S-OFF, etc. my HTC Desire Z which is on Bell's network with a data plan and everything, and everything was going pretty well. Then I downloaded this ROM (http://forum.xda-developers.com/showthread.php?t=822908) to de-brand my phone and it worked as well and everything is fine, except for one thing. The mobile network isn't working. My Wi-fi and normal cellular network that handles phone calls and SMS works, but I can't access the internet when there is no Wi-fi. Normally, when I would connect to the network, an icon would appear in the status bar showing when it was sending out and receiving information and what kind of connection it was (3g, etc.). Now, it doesn't appear when I turn on the Mobile network and I can't connect to the internet without Wi-fi. If anyone could help me fix this, I'd really appreciate it. Thanks.
Is it enabled in the settings and did you choose the right network type to use?
I recommend setting it to automatic.

Yes, and yes. The network is set to bell and the network selection is set to automatic.
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. can anyone help me please?
i have recently updated my sgs2 to android version 2.3.6. i noticed that network data mode doesn't seem to be working correctly. even if i have enabled it already still no connection. The notification icons are not even showing. Already enabled the "use packet data" setting under mobile network settings but still not able to connect. also tried resetting the apn settings still no luck GPS icons are also not showing when trying to enable via the notification bar.
Is't possible to insert a "data switch On/Off" in those already present in the ICS system tray notifications?
Dont think so. The closest thing is probably airplane mode.
Airplane mode is valid choice but i want preferably option for turn on/off mobile data connection only
Well i dont have a 3G device, so I cant confirm this but... You can turn on wlan while airplane mode is active, without disabling airplane. Doing that should keep your mobile connection off, while still allowing you to use wlan.
Its possible some custom rom have a 3G setting you can add to the toolbar. EOS got a lot of different options you can add, but as far as I can see, no 3G.
