Captivate Turn off Mobile Data?

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.

Disable 3G/ Use EDGE Only

For all the people that need their battery for a day or more I wanted to add the instructions on how to disable 3G.
Go into the dialer and type in *#*#197328640#*#*
Select "Debug Screen" on the menu
then hit "Phone Control"
then "UE State Control"
"Change RAT to GSM" will turn off 3G access and will leave your DATA on 2G.
This will save lots of battery especially for those who have low 3G signals.
Please note that rebooting the phone or even turning on "Airplane mode" will reverse these changes.
This means you will have to change the settings again (this is also the fastest way to cancel the changes and go back to 3G).

Thanks a ton for this. I'm sure it was in another thread, but I always saw mixed reports and hadn't tried it myself.
I have a 3-4 bar EDGE signal in my office, but only a 0-3 3G signal, so this will be a lifesaver.
However, as soon as there's a ROM that adds the force 2G option that should be there back into settings (and removes any other locks AT&T put in the software), I'll probably go that direction just because it is a pretty clunky way to do something that should be an option as is.

I have something to add to this. If you use a reboot or airplane mode to turn 3G back on, the next time you go to turn 3G off, you may need to re-enable 3G (WCDMA) before changing back to GSM. Apparently, the setting didn't get changed in the debug menu even though I got switched to 3G, so I had to put it back on 3G first.

Is this still the only way to disable 3G but leave 2G enabled on the Captivate? The apps in the Market are still all or nothing (3G or no data connection at all).
Thanks!

3G, 2G disabling?
Is there a way to disable the 3G/2G altogether but still use wireless?

You can always put it in airplane mode and then turn WiFi on if you don't want to use the AT&T network at all.

flight mode mod?

Is there a way to configure the flight mode?
Actually the flight mode turn off GSM signal - wifi - bluetooth
I would like to have the choice of what I turn off (or at least only turn off the cell signal and keep my wifi active)
any idea?
Thanks a lot

Root your phone and install cm7 which has settings to choose when wifi enabled then disable data
CM7 SkyRocket

thanks but CM7 is still in alpha and I rather wait for a stable version

One option: Menu.... Settings... Wireless and networks... Mobile networks... and uncheck "Use Packet Data". This will shut off your data connection. Also, take a look at JuiceDefender Ultimate in the Market.... tons os settings to control WiFi and data automatically.

Thanks but in fact it's not my data connection I want to shut off, it's my voice connection. Where I work I have no signal but they have a good wifi, I use Groove IP to receive and make call with google voice.
I want to be in airplane WITH wifi just to keep my battery

Disabling 3G on a TF101G to save battery

G'day all...
I have a TF101G and I have noticed that the mobile broadband seens to be consistently at the top of the battery usage list even when I have mobile data disabled and (get this) even when I have the SIM card removed.
My TF101G spends most of its life within WiFi range and I only need the 3G when it's out of the house.
Does anyone have any idea how to disable the mobile broadband transmission? Maybe I'm mistaken, but it seems dumb that it's still using battery to check in even when I tell it not to use the 3G.
Thanks,
Alex.

How have you disabled it?
I've seen many widgets/apps that say they're capable of disabling APN connections but the only thing they do is modify the APN connection name, so the 3G is still active but it never connects due to APN's changed name. The problem is that since 3G is not disabled at all, it might still use battery.
If you disabled from System > Wireless and Network > Mobile Network > Use packed data then 3G is turned off for sure. Also any system app that could manage that should be able to enable/disable that option.

Thanks for the reply.
I did actually try changing the APN as well as removing the SIM card. I still see continuous battery usage for Mobile standby at the top of my usage graphs in Aplications > Battery use.
I don't actually have the "Use packed data" option under System > Wireless and Network > Mobile Network - I only have Data enabled, Data roaming, Access Point Names, Use only 2G networks and Network operators.
I can always to to flight mode for no connectivity, but I can't for the life of me figure out how I can make the TF101G WiFi-only. Surely there must be some way of doing it. Maybe the forthcoming ICS update will fix it - we live in hope.

Sorry, I was refering to "Data enabled". If "Data enabled" is toggled, 3g is enabled despite the APN name's. Maybe you could try to disable "Data enabled" and see if it doesn't consume more battery.

First thing I tried!
No joy there.

Problem solved.

It's simply a matter of putting it in flight mode and then manually enabling WiFi. It works a treat!

I have now TW 9.2.2.4 FW and still if i do flightmode and then wifi on, i see cell standy as the biggest power consumer . to me it seems somehow the modem hardware is not properly switched off. anyone knows what modem chipset it is? or what could be the reason why this behavior?

If i do reboot with 3G modem off (so flightmode but with WiFi on), i get 'cell standby' as big power consumer after few hours. But reboot with 3G on (but no mobile data enabled) and also WiFi connected, then goingto flightmode + WiFi does not show 'cell standby' in battery chart . I had many problems and reboots with first ICS {9.2.2.3}, hopefully now i can get long and controlled battery life and no empty battery beeps in middle of night.

How to disable just the cellular network?

Does anyone know if it's possible to disable just the cellular network on Windows Phone? I've got an Omnia 7 and all I can do is disable everything or disable 3G. Sometimes I want to be able to ignore all calls and texts but keep Wifi on. Anyone got any ideas?
Thanks

The easiest way is to disable everything (Flight Mode: on), and then enable Wifi...
Hope this helps,
Stephen

@sermann is correct. Enabling the Flight Mode will turn off everything, but you can then manually re-enable things like WiFi. The cellular radio will stay off until you exit Flight Mode, though.
