##DATA# Menu

In the ##DATA# menu, there is a menu tree called EVDO, with a sub selection called "DDTM."
What does this selection actually do? I thought it had to do with calls interrupting data?
I ask because I changed this setting to off, and it fixed the ONE instance I had of the losing the data connection... No reboot required, it just suddenly came back with the roam warning, and I had data again.
And now, even though the setting itself SAYS "ON", when I go to change the setting, "OFF" is actually selected. I still get calls while streaming Netflix, so I'm wondering if something is wrong with this particular piece of the firmware?

im curious to know this too!

With DDTM, whenever you are actively using 3G, it will disable calls as opposed to stopping the 3G in order to take the call. So leaving that off is good, because if you were just chillin' and your phone is in your pocket and it starts syncing...and then you get a call..that call is going straight to voicemail while it finishes syncing.

That's why my wife was pissed, she said she would call and call and i would never answer but my phone never rang. Just changed it to off

Thanks for the insight because I kept getting voicemails without the phone ringing and thought I was just losing my mind

It must have just been a pure coincidence that my data came back (after 5 minutes of no radio indicator, and error 97s) when I toggled that.
I hate coincidences!

[HOW-TO] Get a Data Signal While Roaming

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.

Phone won't connect to network.

Hi I have a GSM Galaxy Nexus and today I simply stopped receiving signal on it. I don't know how or why. I didn't flash anything or even use my phone at all. At one point it was working fine, then I noticed that where my signal bars should be, I have nothing but greyed out bars and an "X" on top of that. This was hours ago. I called T-Mobile(I use T-Mobile Prepay) and they had me do several things like remove battery and sim, and nothing helped. I have a custom ROM(Black Bean). I have used this ROM for weeks with no issue. Just to make sure I did a nandroid and I restored my old Stock-Rooted ROM. Still no signal. I then did a full wipe did a full wipe and installed Black Bean 3.1.2(older version which I know for a fact works fine) on a clean install. Still there is no signal. If I try to make a call, it tells me to turn off Airplane mode before making a call. But I am 100% that Airplane mode isn't on. I can go and turn it on, then back off even. Still I have no signal. I have no way of knowing if this is my phone or T-Mobile having tower problems. I called but they don't know anything since it was the pre-pay support line call center in India.
I have been generally disappointed with T-mobiles service. I would gladly give up the rest of my current month and re-subscribe to Straight Talk with ATTs Towers right now, but I'd have to get service going with them again and that would cost 45 bucks. And it's a waste if there is something wrong with my phone. So now I don't know what to do! =/
Edit: Quick update, I put in my Straight Talk SIM thinking that even if it were out of minutes, it would at least let me connect to the towers so that I can add more. Still nothing. If I hold down power(under stock) it brings up the power screen and that tells me that Airplane Mode is on even though I have it off in settings. If i click on that message, it says "Airplane Mode is OFF" but it isn't really, because if I go out and back in again, it's back to saying that it's on. However, I do have it turned off in my settings. I will also mention that WIFI does work.

Check if you activated the 2G option under Mobile settings. I had a similar issue a few weeks back. Almost drove me mad.

Sounds like your phone is the problem if there's discrepancies about whether airplane mode is on.

[Q] Cannot turn off constant Data Roaming Notifications

Has anyone else been seeing near constant Roaming Notifications? The little triangle up int the notification bar.
I have unchecked everything in Roaming Guard and I am still getting the notifications. Is there some other setting to turn off these notifications?

I'd like to know how to stop these as well. Tho, mine wont let me uncheck the ones under GSM roaming. I thought I glimpsed somewhere that the way to turn that off was to remove a particular apk file and folder in the systems folder... but I can't find it again.

Mine remain checked as well, though they remain grey so I am not concerned with them. The only way I have been able to eliminate the messages is to change Settings>More Settings>Roaming>Roaming Network
Change to "Home Only". This is my workaround, but I dont think its the answer as I believe it eliminates additional roaming networks.

I get them all the time too and they're annoying. I ignore them. Now it's like the Boy who cried Wolf.

I turned my setting to sprint only instead of automatic roaming and I don't get the notification anymore but I will probably not be able to roam when out of sprint service area as well

I get them to and have changed the setting and they always revert back to the original. Getting very angry. How is this stopped?

Has anyone been able to resolve this?? its freaking annoying! the dang thing wont stay off!

Anyone ever find a way to delete the dang notification? Just really annoying... If someone can give me a starting point, I could try diving in, but I have no idea where to start.

Have any of you guys tried turned off the sprint connection optimizer? I've read somewhere that it stops these notifications.

I never thought that might be what keeps the network data notification going, you might be right. I had the Sprint optimizer disabled but when I went into mange apps it showed it disabled but there was a little box checked for notifications. So, for good measure I uninstalled the app completely. I'll report back with the results in a while... I hope that eliminates that annoying crap! Thank you!

UPDATE: arrrrrrrRrrggghhhh ! Still popping up.... thanks anyway. There has got to be some line of code to remove, I just wish I knew how to find the offender.

I have these roaming notifications also. Just ignored them. I'll see if I can stop them and report back.

Did anyone ever figure this out?

I'm having a problem trying to disable the Roam Guard settings. The Roaming network is set to Automatic, but I cannot un-check the Voice and Data (actually it prompted me when roaming and had a little check box to not show again for Data, but Voice is still selected and doesn't give the little check box to not show again) roaming guards for Domestic Data or International Data with exception to "Outgoing SMS" in International. I am stumped. Had them unchecked before, but had to change the Roaming network to "Home Only" because my phone was having trouble connecting to an Airave. I immediately switched it back to Automatic once it connected, and now I cannot disable the Roam Guard
Any ideas? Screen Shot attached.

1. ##SCRTN#
2. Reboot
3. Hands Free Activate
4. Reboot
5. Update Profile/PRL
Roam Guard boxes should be restored / not grayed out.

Sprint LG G2 (LS980) Data Roaming Bug

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.
