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.

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 work in midtown Manhattan, and in my particular building, ATT's service is very spotty, specifically where I sit. You'd think the 28th floor near Times Square would get great reception, but I don't. Oftentimes my network connectivity will go completely blank w/ absolutely no service, then turn back on. I've called ATT, switched to a 4G sim card, they pushed updates, rebooted my phone, etc. all to no avail. I still get very spotty service.
EXCEPT I just figured out if I have an app w/ streaming data running (run once there is an initial connection of course), it actually maintains the connection (currently using the streaming music app "di.fm" and "sky.fm", Pandora would prob work as well). I'm assuming this is because the phone locks onto a specific tower and doesn't let go as long as the app is accessing the data continuously.
Is there a way for my phone to stay connected to a specific tower and not jump around without running a streaming app? Any help would be much appreciated. Thanks!
I hate to say this but it's your area during peak times. I work downtown near the Brooklyn Bridge and experience the same thing. Until AT&T finishes the backhaul this is what we're stuck with. Build props and other mods are shots in the dark but won't help much.

But why am I able to maintain connection when running a streaming app? If traffic was the reason why my connection was dropping, wouldn't it still do so?
I think the tech guy said something about how my phone would try to connect to a tower 20 miles away when there are half a dozen right around me. When my phone does have reception, it's probably because it's hooked up to one of the close local towers, and running a streaming app forces it to stay locked onto that one...

When idle it's easier to drop connections as the phone switches frequencies. Here's a couple of things to do if you haven't done so already.
Make sure you're running the stock radio, if you haven't flashed another radio you're running the stock one.
Change to usa bands only. Open the dialer, press: *#*#4636#*#* Go to phone information. Press menu then press select radio band. Then select USA only. Give it a few seconds while it reconnects.
OK I'll let you know if it maintains network connection any better.
Also, what about the preferred network type? The options I have are:
- WCDMA preferred
- GSM only
- WCDMA only
- GSM auto (PRL)
- CDMA auto (PRL)
- CDMA only
- GSM/CDMA auto (PRL)
- Unknown
It was previously on WCDMA preferred, but should it be GSM/CDMA auto (PRL)?
So...I am at an office today that I have zero cell coverage since I am in the basement sitting in a network closet. I enabled WiFi calling and I am able to place and receive calls. However, when the screen goes off and the phone locks I do not get any inbound calls. When I call from a land line the call just rings and rings and rings and never gets VM and my cell phone does not ring.
Has anyone else played around with WiFi calling and seen this behavior? I am assuming that WiFi goes into some type of power save mode and disables the WiFi radio when the phone locks.

Sounds right. I don't have my Sensation yet, and have never had an HTC (gotta switch from my Vibrant this week due to GPS issues), but it looks like this may solve your problem.
Menu > Settings > Wireless and Networks > Wi-Fi Settings
On the Wifi Settings screen, press the Menu button and choose Advanced.

Yah...I already tried that. I checked Best Wi-Fi performance and adjusted my Sleep policy to never. Still no dice. I have even noticed that it doesn't always ring right away when unlocked. This is a very poor performing app IMO. It seems to work well if you need to make a call...but inbound is unreliable.

I still see my phone connect or at least check the connection over the network not using WiFi though. My WiFi signal is strong and I'll see the 2G signal pop up for a second and then go dormant again. So something is definitely checking but yeah pretty much everything goes out over your WiFi connection but the radios do turn on from time to time from what I can see.
Seems to be working on my home network fine CMY ..
Can receive and make calls ok ..
I have mine set to ..
1. WIFI Sleep - Never ( However I changed it to 15 minutes then back )
2. Best WIFI Performance
I did notice you have to press the menu key and pick SAVE

Seems to work at my other office today. I have it set to WiFi Perfered. The only differnce here is that I actully get GSM signal in most of the building. Anyways...I'll do more testing when time permits and report back my findings. Thanks for all those that chimed in.

cmy,
Have you had any luck solving the wifi calling or GPS lock? My Sensation takes forever to get a GPS lock (if at all sometimes) - way slower than a friend's G2. I've had luck setting the wifi calling to cellular preferred. That seems to have helped me, based on what testing I can do. In your case you need wifi preferred and I'd like to be able to use that option too. Is it possible your office (and mine) is blocking something on the wifi network that is preventing it? At home, I haven't heard of anybody calling me and it not ringing - just at work.

Wifi calling = FAIL unless with google/voice.
Tell your provider to suck less and reinvest.
Wifi calling is working great for me...I have no reception at my house wifi calling has been a savior. I use the same settings that warlock mentioned earlier
Sent from my HTC Sensation 4G using XDA Premium App
Thanks. I'm going to write it off as my office blocking a port that wifi calling needs, or something like that. I have mine set to prefer cellular and that seems to make it function at work. At home, where I live in a T-mobile deadzone, it seems to switch over to wifi properly.
I am with a carrier (U) that supports 3g in limited areas, outside the coverage, I will be switched to another carrier (C), but only with EDGE connectivity.
I am living in the 3g coverage area, but somehow the car park is not covered, so everytime I go to my office car park, it switches to C, and when I am back in the ground floor and up, I noticed that sometimes its very slow in switching back to the carrier U.
I have called U up and they asked me to use the "Select Network Automatically" settings, but that doesn't seems to help much as sometimes even after 30 minutes it didn't switch back, until I go into the network settings.
I have noticed this too.
I an on Sprint. If my phone switches to 1x cdma (slow), it may not switch back to 3G if I am actively using data. I have to uncheck and recheck "data enabled" to bump it back. It seems to switch back ok if data is idle.
hmm, wonder if I could do something with tasker about this.
I have quite a specific problem:
I live near the national border and my mobile network selection has to be set to manual, because otherwise it would randomly switch to roaming on a network from the other country, even though my home network coverage is practically 100%.
But quite often I do cross the border to area out of reach from my home mobile network and then I have to set it to automatic or manually select foreign network.
Now, the problem is when I get back home, i have to switch again. This switching is often and annoying. And forgetting to switch can also be expensive.
So I'm searching for an app that would allow me to toggle a switch (widget preferably) that would change network selection setting to automatic when i intent to leave my country and switch again to set it to manually connect to my home network when i come back.
Does any body know about an app that would allow me to do that or does anyone have a similar problem?
I'm thinking about creating an app like this though.
Similar Problem... Setting Preference Order for Mobile Networks
I have a Moto G 2013 running Android 5.0.2.
In Bangalore(where I live), Airtel has the highest 3G coverage. But I am on Vodafone (more coverage in my area and less tariffs) which does not have its own 3G network yet. So I manually set my network preference to Airtel while I'm outside. But I need to manually change the network back to Vodafone at home if I want to stay connected.
Setting to Automatic does not help as it always chooses Vodafone and so no 3G.
So I would like to know if there is any way to solve my problem and if there is any app to set preference.
Thanks a lot!
