Disabling roaming overall.

I just got a new FUZE and I'm already annoyed with an issue I'm having:
Halfway on the way home my phone kicks over to my neighbors to the north - Robbers Wireless. I live fairly close to the Canadian border and my FUZE seems to like Robbers more than it does the Deathstar, leading to roaming charges up the... you know.
Is there any way of disabling roaming of any kind, be it voice or data, preferably automatically? People suggest NoData.cab, but that is no good to me - I'll not notice myself hit the Rogers towers until the last second - hitting Home and seeing "Rogers Wireless" in my upper left corner. My phone never alerted me to data roaming yet it kept a data connection open the entire drive home and hopped to Rogers.
I kept trying to select networks from Start > Settings > Phone but it kept locking onto Rogers and didn't offer me a choice of AT&T at all.

Have you tried choosing your network manually instead of automatic?

Doesn't give me a choice if I'm looking where I should be.
Start > Settings > Phone > Network shows only 2 things:
"Current Network: AT&T"
and a [Find Network] button. No network selection or anything was offered to me.

Call AT&T and tell them to disable international roaming.

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.

[Q] Modifying APNs with 4.4.2 (NE1)

Hello,
I've been putting off asking the question as I thought that somebody else had to have gone through this already but I've had poor luck looking through the forum and Google hasn't been able to help.
I'll be traveling to Italy in the near future with my Verizon Samsung Galaxy S3 (Build KOT49H.I535VRUDNE1). I would like to pick up a TIN or WIND SIM while I'm there, primarily for data usage. From what I've read, once I install the 3rd party SIM, I'll need to update the APN settings to get data to work.
Stock, it looks like the APN settings are uneditable. I rooted the phone with towelroot (if only everything were so easy) and then checked the APN settings to see if I could add another network. No dice.
Poking around on the web, it looks like in the past, people have been able to work around this by downloading build prop editor and adding the following two lines:
ril.sales_code=LOL
ro.csc.sales_code=LOL
I gave this a shot and was surprised to see the APN menu gone when I went back into my network settings. Through trial and error, I determined that the inclusion of ro.csc.sale_code=LOL changes my Mobile Networks options from:
- Mobile Data
- Global Data Roaming Access
- Roaming
- Signal Strength
- Network Mode
- Access Point Names
- Network Operators
to:
- Mobile Data
- Data Roaming
- Network Mode (GSM is not an option in here)
- System Select
- Dial Up Networking
There is no option to modify APN settings there. Am I missing something silly? Did something change in KitKat 4.4.2 that has caused this approach to "unlocking" the APN settings to become invalid? Is everything really ok and I'll have access to the APN settings when I insert the italian carrier's SIM card?
I'm game for other approaches as well. At one point, I thought I saw an article that talked about setting up a pointer to the APN settings prior to updating the prop file but I haven't been able to relocate that.
Any suggestions would be appreciated.
Thanks!
Aaron

In the event somebody else is looking for the answer, I got my hands on a TIM sim card today, installed it in the phone and the APN menu reappeared and let me enter a new APN. Looks like the answer as of today for this phone is TowelRoot, SuperSU, BuildProp and install the 3rd party sim.
Take care,
Aaron

Seem to have lost 3G data after factory reset (4.1.2)

I've been running a flashed 'official' 4.1.2 (Singaporean origin ROM?) for over a year now but recently have been experiencing performace niggles. Therefore I decided to do a 'factory data reset' from the settings menu to clean the tab up. It was never actually wiped before as even when I went direct from 3.2 to 4.1.2, all the applications were kept in place, so I figured it could do with a good internal flushing.
After reinstalling my apps, everything is indeed running smoother and with no real performance complaints. However, I seem to have lost my ability to use the inbuilt 3G modem for data. It still registers with the network provider as per the SIM card (in this case, o2 UK) and I can send txt messages to the number so it really is on the network and working to some degree.
Despite this, I don't have a network connection via 3G nor do the indicators of network data connectivity show on the bottom status line irrespective of whether nor not I enable 'Mobile Data' (i.e. I can't see the little 3G/HSDPA indicator or the up/down arrows). All I see is the reception strength indicator, whichever way I set 'Mobile Data'.
WiFi is still fine (subject to the 2.4GHz only restriction of the ROM).
Anyone have any ideas what I should do?

Just to follow up - the problem was more basic than an issue with the tablet hardware or flashed OS. It was an APN configuration issue. Basically the auto installed APNs were wrong and I had to manually configure a suitable APN for my pre pay mobile broadband.

Is it solved? Please update main title to SOLVED

Help request: LTE Data works,"no service" otherwise. IMEI/number, but no texts/calls.

Help request: LTE Data works,"no service" otherwise. IMEI/number, but no texts/calls.
Software: Android 5.0.1 Skydragon M8 v2.0 Sense 7
Many people have posted issues with LTE where their cellular signal was fine for "2G" functions like calls and texts.
I'm having the opposite problem. After leaving airplane mode (landing at an airport today), I have a "No Service" message in the status bar drop down (notification tray), and the Settings>Network information page shows "Not Registered." However, I do have an IMEI (see details below). However, LTE data works perfectly fine.
I've obviously tried changing the settings in Settings>Mobile Data (preferred network to Global / LTE / LTE/legacy 3GPP mode) connection type global/auto/LTE/etc), to no avail. If LTE is connected it works flawlessly, but I cannot make calls or texts, and show not registered on the network. Data roaming is set to deny, but even allowing roaming does not change the situation.
Before this happened, I HAD gone through all the XTended Settings, and even 'looked' at (but did NOT change) some advanced settings pages, including the 'hidden' HTC network info page ( *#*#4636#*#* ). Again, however, I didn't change anything -- unless by accident?!
Does this sound familiar to anyone? Anyone know if I may have inadvertently changed something and can change it back (a setting that would persist in the hardware through NANDROID restores and factory resets...). Or, any other advice to restore the cellular service connection to normal?
I've tried a full NANDROID restore (multiple times) to a working copy, and a factory reset. I have limited access to a PC since I'm traveling, so re-flashing the VZW firmware or stock recovery or lollipop/verizon RUU would be challenging.
I did spend a good 45 minutes (at a library, my only PC access!) searching the forums and web, but to no avail.
Settings information:
OPperator Name: Verizon
Signal Strength -114 (I've had better but still have the same issues)
Mobile Network type: LTE
Service state: In service
IMS service state: Not Registered
Roaming: Not Roaming
Phone Identity page:
IMEI shows up (15-digit number...how can I verify I didn't mess this up?)
Phone Number is correct
IP Address: 100.66..... (looks good)
Any help is GREATLY appreciated!

Same here
I'm having the same issue. When i try to make a call my LTE bars drop to nothing and it says call failed no network available. Any ideas or help would be nice. I was using venom rom as well. I'm currently trying to flash the newest RRU to see if that resets things. I'm wondering if it somehow my sim card. I took it from my droid turbo. I've made sure to turn off advanced calling on my VZW account though.

I had this same issue, running from ruu then rooted. I didn't noticed until I started seeing voice mail notifications but never heard the phone ring. When I tried to dial out I got the immediate call lost message. I couldn't figure what was causing it so I just did a reset. I made sure not to restore any systems data from prior to the Lollipop upgrade. At this point everything is working, the only thing I haven't installed yet is the xposed framework and sense 6 toolbox.

What kind of reset did you do? I know my issue is slightly different, but I did a full RUU-flash yesterday (latest lollipop version) and still no luck. Unfortunately I'm out of the country now and access to a computer is limited, and I don't even have a SIM card yet to check if cellular service would work anyway.
I do intend to do a flash of the stock recovery and radios once I have the time and access, but that may be a while...
Still, I'll keep checking this thread to see if anyone posts any other options

Just go into settings and to Backup & Reset , this will return your phone to a fresh install and remove all non bundled apps.
Before doing the reset try going into Settings then Call then change Preferred Network to Global, or toggle from LTE then back to Global.
