This is NOT the "LOS" bug, as its commonly understood, where you lose your cellular service (circle with a line for those who are lucky enough to be informed their phone crashed). This is the dreaded Roaming Triange of Data Death.
Background: Occasionally, when roaming, I lose all data connectivity, and I get the triangle warning in the notification bar that says "You have lost data connectivity be...." and of course, its impossible to read the rest of the warning. Standard deductive reasoning, assisted by posts here, tell me its a probably something like "because of your roaming data guard settings."
Some here have suggested that Samsung phones are unable to roam on PCS data.
What I did:
1) I check my roaming data settings, and I have the option to roam enabled, and roam guards enabled. I disable the roam guard. No data. I check the box again, no data.
2) I reboot the phone, no data.
3) I uncheck both the voice and data roam settings for domestic and international and reselect the domestic. I get the "Are you sure...?" prompt, and select yes. No data.
4) I uncheck the data roam guard, and then go back to Roam Settings, uncheck and recheck data roaming, and voila! I get the big triangle that asks me if I want to data roam, I say yes, and I have data again! 3G, too. I pulled 1.3mbs in the middle of the forest in northern Wisconsin. (I was roaming on Cellcom, apparently)
I was able to reproduce the problem pretty easily... It seems like when the roam guard is enabled, you don't actually get the Allow? Yes/No warning prompt when you start to data roam. However, turning it off the guard by itself didn't fix the problem... I also had to turn off the ability to data roam, and then turn it back on before the phone allowed me to roam.
I hope this helps someone else!

Yes, it's a known bug.
There were several threads about it.
Here's my own.

Well it only asked you because you turned off the Guard. Once you say yes again the Guard is rechecked.

But the guard settings should be permanent. If I have disable the roaming guard, it should never ask me if I want to roam. I shouldn't have to recheck it, and then uncheck it again in order for it to allow roaming.

Hello everyone
We will be moving close to the border soon and I noticed our devices (my wife also has a Desire Z, though it is stock) tend to connect to services from across the border.
Now having turned off data roaming, this isn't that big of a deal but roaming calls still cost more this way AND I can't use navigation because data roaming is deactivated.
Now I know I can set my preferred service provider, but can I also lock it (meaning: turn off roaming completely) so I have to manually allow roaming to accur when, and only when, I truly need it?
If you go to Wireless and networking settings you can select "mobile networks", the same screen you select dataroaming...
you can select your mobile provider I think that when you select Search for network and you select one network it won't automatically select a new one if your connection gets low.
That's what I thought, too, but in reality, it didn't really work. Although I have received a hint that it might only work if mobile data was deactivated at that moment. I'll try this thursday... let's see what happens.
I'm running ACS recovery/kernel + root; and it was also true with Zedo v2.
I cannot get any data while roaming. I have installed and run roam control. I have tried all possible options under Settings/Wireless and Networks/Mobile Data and Roaming.
Anyone else?
Edit:
Problem was fixed - see post#6

Where do you live?
no seriously
The ET4G, like previous samsung phones cannot roam on the PCS band, so if whoever your roaming on is only throwing voice over the cellular band and data over PCS then you got no data.....
No one seems to care about this bug and I don't get why not.

I'm going to have to go somewhere and roam now...(I purchased Roam Control a year ago for my Moment, but I don't want to root my ET until there is an unroot method)
I ALWAYS had data while roaming with my Samsung Moment. Granted, sometimes it was slow as molasses, but I always had it!
I'm actually seriously considering turning this phone back in... With Sprint's crappy network, once you get inside a building, often the only signal you can get is a roaming cellular signal... which makes the GSII a hair more than useless.

I had this happen. I had to go under Wireless and Network then to Roaming. Uncheck all settings in Roaming guard and Roaming settings. Reboot phone then go back and check everthing under Roaming settings again. I think I had to enable the data block under roaming guard. Anyway - it finally told me I was roaming and asked for permission to connect to data. Also using Roam Control.

Thanks. That actually fixed the problem. More can roam with data.
The settings for data roaming on this phone is confusing. At first I was getting messages that I am getting into an area where there is roaming and click on roam to continue even though I am at home where I have service without roaming. I clicked never show this message again and clicked roam. I still get the message. Also when I woke up this morning the signal bar had a triangle above it while the bars were unlit as if i didn't have any service and then in a second it returned to normal. It also does that frequently when I have 3g off and on. What is the meaning of that?
How I do I set up the data roaming where I don't get messages? What is data guard? Also how do I set up the data roaming options where I can save battery.
What is everyone setup for data? Do you guys have it as sprint only or automatic? I would appreciate anyone's help. Thank you.
put ur roaming into sprint only by default its on automatic.
If I turn it off and go to an area where I don't have service, can I turn on roaming manually to see if I get service?
Background:
Ever since I've had this phone I couldn't get a data signal while roaming in areas where I knew one was available. Old phones would get data while roaming without a problem.
The Epic Touch would just give a notification saying "you have lost data connectivity" or something.
I understand certain Sprint roaming areas just plain don't have data available. This howto can not fix that.
What this howto does help you do is get a data signal while roaming in areas where a roaming data signal is available.
Credit:
This was apparently discovered by someone on the sprint forums, and I found a reference to it on the Android Central forums, so I do not know who credit goes to for discovering this.
What to Do:
It's best if you are in a roaming-only area to test this, or if you can force roaming. You'll also need to be on the stock kernel (rooted is fine) so you have the ability to update your Profile.
Let's do that now. Go to the Settings menu and tap About Phone - system updates - update profile and wait for it to complete, then tap ok.
From the home screen, tap Menu - Settings - Wireless and Networks - Roaming - Roaming Settings.
Un-check all options here (voice and data for both domestic and international)
With no boxes checked, tap the "Data" box under domestic roaming. Tap only this one, not voice.
You will get a box asking you to confirm. Click yes. This will then automatically enable voice as well.
Another pop up with a red box will ask if you really want to use data while roaming. At this point you can tell it to never ask again and click Roam.
Now you can use data while roaming where it's available!
Update:
after trying this multiple times to verify it works, occasionally the final pop-up with the red box disappears before you can read it. I was able to long press the home button to show recent apps, then tap the "Data Roaming Guard" app. Then I could tap Roam.
This is critical for me as sometimes I am in roaming areas for work and I need internet and this phone is the only access I have. Now I can use it!
Report back with any corrections or feedback. Mileage may vary.
I don't know if it's necessary to update the profile. I have that step in there because that is the sequence I used. If you try it without updating the profile, let me know. This would allow people on a custom kernel to do this too.
I spent an hour and a half with Sprint yesterday on the phone trying to resolve this. They turned me over to new reps three times (including to the international support department) each one not aware of my issue so I'd have to explain everything again.
Finally I started digging on the web and found the tip on AC. Took me 2 minutes.
DOH! Stupid Tapatalk.
Mods, please move to General. Didn't mean to start this in development.
Thanks for sharing this. I will try this out.

I have the same issues. My girlfriend has an EVO and she will have data while roaming, and I wont. Even if were right next to each other.
Thanks, this worked great for me & did not have to update profile. I am on stock rooted deodexed rom.
Worked for me! Thanks, that was very annoying!
thanks! now i can play wwf at work lol
I did this awhile back when I saw it on the AC forums. I also read this phone cannot roam on PCS networks because of a limitation in the radio so there still may be times it won't roam when other phones will.
Greetings All!
I was able to make roaming calls before; but I followed these instructions and now I can use roaming data as well. Fortunately Atlanta is a pretty good 4G metro area so I rarely need to use roaming data. Usually either 3G or 4G is available. Nonetheless it's nice to have the option.
FYI I forced roaming by using the Roam Control app and have verified that for the first time with this phone I have a nonzero "Sprint 3G Data Roaming" entry in the detailed usage screen on the Sprint website.
Many thanks!
Cheers, Henri
Ok, glad this is working for people! I know it was the biggest gripe I had about the phone by far.

Agreed. And such a simple solution. Thanks again.
Does anyone experience this scenario where the "Data Roaming" check box seems to uncheck itself in Settings/Mobile Data (hit the Menu button to check "Data Roaming" on)?
Even if I have it set on to Data Roam, every once in a while, it seems to uncheck itself. How do I know this, there's a certain section in the building I work where I usually always roam on Verizon (voice and data, no problem) and previous phones I've had (Note 2 and iPhone 5s) would roam just fine.
With the G2, I'll notice that a triangle pops up in the top left telling me that I've lost data connection because I have Data Roaming turned off. Of course I set it to data roam.
Lo and behold I go into Settings and Data Roaming has turned itself off again, so I check the box to Data Roam and data starts flowing. It will stick for most of the day or two until I notice it again, and the cycle repeats itself.
It gets really frustrating if I don't notice this phantom behaviour because I could be in this particular location for quite sometime and not notice that I don't have data because it's unchecked itself, again.
Anyone?
Mine will stay ticked but ***** that it is disabled. It's annoying.

I have a similar problem in that the box will stay checked, but I get "Data Roam Guard" notifications all of the time, even though I have the setting to not get the notifications. When I click remember this setting it doesn't take, and I also get the triangles regularly. It's very annoying.
Sadly I've gone back to my 5S. Just couldn't take it anymore constantly losing data where I never did before. Still keeping the phone hoping a not too far in the future update helps.
I can't believe this isn't happening to more people. Can't even find an inkling anywhere. Weird bug.
Very annoying. I have the same issue.
Just got my lg g2 2/15 great phone and i too am having the same issue is there a fix yet? i to am in and out of sprint service and have to keep turning it back on (put a check back in the roam box)

I Guess just a few of us have the data issue so short of returning the phone i called sprint to see if they had any ideas. had them create a trouble ticket to address the issue so will give it a few more days see what happens. Other than this major bug phone is great.

It seemed to only happen after the recent OTA update. I got so frustrated I reset the phone to factory, but still no fix. Anyone have an update on this bug?
On 4.4.2, same issue, no update here.
