Enhanced 4G LTE Services - AT&T Samsung Galaxy S 5

Running Safestrap with NF6 custom rom.
Today flipping through the "Mobile Network" settings, the "VoLTE" option changed to "Enhanced 4G LTE Services". "Enhanced 4G LTE mode" is checked. The description says "Turns on enhanced voice and communications using LTE data (Recommended)". It used to be "current firmware version does not support..." when I check the VoLTE box. Does anyone know what exactly does it mean?
And how does AT&T get into my phone when I run safestrap with custom rom?

I'm also wondering if this setting impacts negatively LTE speeds. On a stock ROM taken from the 2.23.5.2.3 RUU, this option doesn't even appear, and I can easily get 40Mbs down. On another ROM, taken from the same stock update, the option is there and selected by default and cannot be de-selected. The most I can get is 5Mbs, which is basically HSPA.

More data roaming problems - Verizon EVDO

I'm getting a chance to do some extended testing with data roaming. I found a couple of other data roaming problem threads, but this issue is different than the problems discussed in those.
The HTC One is rooted, unlocked, S-OFF, stock 4.4.2 (4.06.651.4), with PRL 56018 installed from CDMA Workshop. I've installed a couple of the patches floating around for WiFi tether. I also have an HTC EVO 4G LTE with the 56018 PRL installed via QPST.
Right now, I am in an area with extremely weak Sprint signal and decent Verizon signal. The EVO 4G LTE finds Verizon 3G EVDO and will voice/data roam just fine. SignalCheck verifies that the provider is Verizon for 1x and EVDO, with signal between -90 to -100 dB. However, the One will not data roam. SignalCheck indicates that the One finds Verizon for voice (1X), but does not connect for data roaming. If I watch SignalCheck long enough, I can see that the One will find the Verizon EVDO for a few seconds every five minutes or so, but it won't "hold" the EVDO signal. On Sprint, the ONE will find both 3G and 4G.
I've played around with various mobile data settings, but nothing seems to help. In fact, the One will pop up the messages that data roaming is in effect, but there is no data connection. Since the EVO 4G LTE will EVDO roam, it seems that the One should EVDO roam as well.
Any ideas or suggestions on what to look at? On Sprint the 3G is usually ePHRD, not EVDO, perhaps there is some issue with EVDO on the ONE? I thinking about getting Roam Control to see if that would make any difference. I haven't taken the 4.06.651.9 update either.
Thanks!
I had a chance to do some further data roaming testing with the One and Evo 4G LTE side by side.
Roam Control seems to work fine on the One, except that the color of the blue button for selecting the roaming mode is hard to distinquish.
Unfortunately, it seems that the One will not lock on to a Verizon EVDO signal. I found several areas with strong EVDO signal. The EVO connected just fine, but the One wouldn't. The One does fine with Sprint's eHRPD signal, and will lock on to the Verizon 1xRTT for voice.
I don't know how to do further debugging. I guess it could be a radio problem, an issue with the 56018 PRL and the One, or some other issue.
Any suggestions are welcome!

Providers dont like roaming, the newer the phone is the less likely it will be to roam, the first two M7 radios would not allow any roaming at all on my phone, the latest 2 do allow roaming but I need to force "roam only" with roam control, I am on the latest radio running GPE rom and use roam control to force roaming whenever verizon has a better signal and it works good. I am using PRL 56015 flashed via CDMA workshop.

Unfortunately, my One will not data roam, even with Roam Control. It sees the EVDO for a few seconds, but won't hold it.
Would there be any tweaks that could be made to the radio from CDMA Workshop that might affect the data roaming behavior?

I loaded PRL 56015 into the One with CDMA Workshop, but the problem remains...when roaming, the One will see the EVDO briefly but not hold it, according to SignalCheck.
I did a comparison between the various settings in the One and the EVO 4G LTE (where roaming works fine) using CDMA WS. The are significant differences, particularly on the CDMA, CDMA-2, and EVDO pages. For example, on the EVDO page, the EVO has a username ([email protected]) for HDR_User_long, but the One doesn't have one. The EVDO revision is also different. I don't know enough to fool with these settings.
Actually, the One is missing values for many settings that the EVO has. I'm beginning to wonder if somehow the One didn't get provisioned properly.
Thanks!

If you change any of them settings in CDMA workshop, save them first, if you screw something up you can reload the saved settings, I screwed with CDMA workshop alot in the past and you can do alot with it. Before screwing with them settings, did you try resetting or updating your data profile?..maybe something got messed up in the tweaking and flashing your doing. I flash all kinds of different stuff on my phone, every once in a while I flash a sense rom and update or reset my data profile just in case...

I am not on a sense rom right now and I forget the codes, try entering ##3282# or *#*#3282#*#* in your dialer, it should bring up a data menu, there should be an option to do a reset, it will basically erase your data profile and reboot, when it reboots it will do an activation and reset everything....or ##786# will completely reset everything, that has saved me once or twice but that also factory rests your phone. these will only work on a sense rom and I reccoment a backup before doing anything, just in case... if that dont work do a google search for epst codes, and find the one that resets your data profile.

I did a profile reset with ##3282#, and the behavior has changed somewhat. The One is now holding the EVDO signal according to SignalCheck. However, if I try to open a web page, a message box pops up indicating that data roaming needs to be enabled. If I tap on "data roaming" in the message box, it takes me to the mobile data settings. I have been over and over those settings, and tried different combinations of things, but I can't seem to come up with the magic setting that will make the phone think that data roaming is enabled. I am forcing roaming with Roam Control.
Is there some "hidden" setting to enable data roaming? There is a "CDMA Roaming" setting that has choices of Home/Automatic, and I have it set to Automatic. I have identical settings to the Evo in the mobile data settings, but I can't make it work on the One.

What rom are you using?, I think the stock roms from Sprint no longer have the "allow data roaming" option, Sprint tries to avoid us using roaming as much as possible, so if you are on stock rom or something close, you probly don't have this option, try flashing a modified rom that may have this option, or if you are familiar with using the exposed framework, I think there is a module you can use to enable the data roaming. I personally use Gruesomewolf's GPE rom and it has the option built in if you want to try it.

I'm on the stock 4.06.651.4 ROM (rooted and S-OFF). This is my wife's phone, and I'd like to keep it stock and simple, as she's not a techie. However, she also travels where data roaming is required, so I might have to try another ROM.
Interestingly, My EVO 4G LTE doesn't have an "allow data roaming" setting under mobile network settings that I can find, but it roams just fine. In fact, the mobile data settings on the EVO and One are almost identical, except that the One has some additional GMS options. I wonder if there is some setting in a file like build.prop that affects data roaming.
I installed a couple of native hotspot hacks on the One. In looking through the zip files for those hacks to see what they actually did (which was quite minimal), some network-related things were changed in /system/customize/ACC/default.xml relative to the file in the original ROM, and a shell script was added that executes several iptables commands. I may try to manually undo those hacks to see if it has any effect. At this point, we need the data roaming more than the hotspot.

Alot of your issues can be solved with a custom rom, you wouldnt need to install the hotspot hacks either, most have native hotspot built in.

Getting a chance to work on this issue again...it seems that the EV-DO problem with my HTC One is not limited to roaming, but also occurs on the Sprint network.
Again, doing side-by-side comparison between the HTC One and my EVO 4G LTE on Sprint network:
1) Set network mode to LTE/CDMA. According to SignalCheck, both phones will find Sprint LTE and display the 4G indicator in the status bar, and both will occasionally drop back to Sprint eHRPD for periods of 5-10 minutes (displaying the 3G icon in the status bar). Network is available to apps in both the LTE and eHRPD cases. No problems here.
2) Now...change network mode to CDMA Only. According to SignalCheck, the EVO will find Sprint EV-DO, the status indicator will change to 3G, and network is available to apps. However, on the One, SignalCheck indicates that EV-DO is found (but doesn't indicate which carrier), there is no 3G (or 4G) icon in the status bar, and apps report that there is no network. The EV-DO signal is strong for both phones.
So, it seems that on the One, LTE and eHRPD are working, but there is some kind of problem with legacy EV-DO, where the phone can find a signal, but can't complete the process of registering on the network, whether Sprint or roaming.
Do eHRPD and EV-DO use the same radio? Trying to rule out a hardware issue. I am thinking of flashing a different radio firmware. Perhaps something got corrupted when I did the OTA update.
Not that Sprint wouldn't do this, but it would seem odd to put something in the stock ROM that would prevent EV-DO, even on Sprint's network. Is there somebody out there on the stock ROM who could confirm that they can get network in CDMA only mode?
Thanks!
So, I finally got this problem solved! I had to do a ##786# "hard reset". After the reset, EV-DO works fine.
The reset process was interesting. I did backups, expecting the phone to be wiped. I entered ##786# and the phone said it was preparing, and then rebooted. But it rebooted into recovery (I have TWRP). Not being exactly sure what to do, I rebooted into the system. The phone booted up, and the provisioning process started and completed. It then fetched the PRL. But nothing was wiped out. Apps, data, and sdcard were all intact. Oh, well, no complaints, and everything seems to be working fine. I used CDMA workshop to put PRL 56018 back, and roaming seems to be working.

I know you got your issue fixed and its been a while but just a heads up in case you run into problems again, I got a replacement phone from sprint and had the exact same issues youe were having, It is a problem with the data profile not being configured correctly, in my case, the new phone did not have my user name correct, worked fine on sprint network for some reason, but I couldnt get 3g in roaming areas, using epst I put my correct user name in and everything worked perfectly...dont know what rom your running now either but NUISENSE is awesome with this phone and it has "roam only" opttion built in, no need for roam control app....
Thanks for the tip!
I'm using the stock ROM. Since my last post, I have been able to test romaing, as we've traveled off the Sprint network, and roaming 3G worked fine. The only issue was that in a one spot we were roaming on a regional carrier, and the phone had locked on a quite distant tower according to SignalCheck, instead of Verizion which had closer towers. This resulted in some loss of 3G just as we were trying to get radar data for a storm we were traveling through (bad timing). But that is most likely a PRL issue. In looking though some PRL analyis an earlier version of 56xxx on another site, Sprint apparently doesn't have roaming agreement in this particular area with Verizon. I wish I new more about PRL editing so I could fix that...

[Q] How to force Moto X Developer edition (Verizon) to use only 3G

PagePlus does not activate an LTE phone on their "low-end" plan but allows a modified LTE phone to be activated. I used an app to make it CDMA only but PagePlus still cannot activate it saying it has some issues because their system still thinks it is LTE. I wonder if I have to something special on the phone.
I unlocked fast boot. The phone is not yet rooted.
Any help is appreciated.
Network connections? Set preffered to 3G/2G.
@kyzn is right with going to Settings > More > Cellular networks > Preferred network type and selecting 3g. This does not mean it will be in 3g only because 2g is there for a backup network signal in case that the 3g or higher signal is lost. Shouldn't be problem for you with what you are asking.

[Q] No Mobile Data on Verizon Moto X with AT&T sim.

So I have a Stock Verizon Moto X 2013 with an AT&T sim. SMS, MMS, and Voice all work. The only thing that doesn't is the Mobile Data. I have tried to manually change to APNs, turning off radios and network refreshing. When I am not on Wifi, the celluar signal looks fine, containing white bars. However, as soon as I go off WIFI connection, the celluar signal immediatly turns orange in the Quick Notifications toggle. Please. I don't even want LTE, just some 3G would be nice. How can I fix this?
I'm also running a Verizon phone on AT&T, and 3G data does work. I'm not sure I can trouble shoot your specific problem, but I can tell you what worked for me.
I ditched the stock ROM, and installed Krypton 1.4 ROM. Then I installed Xposed and the GravityBox module.
This gives you access to the custom mobile network settings, "preferred network type", "select network", and "network mode" (see pics).
Using these settings, I get HSPA connectivity.

M7 no option to enable 4G LTE

Hi,
I spoke to my service provider and they enabled 4G on my account.
I then went into their shop and got a new SIM card, as my old one was 3G only.
So now I have 4G on my account, and a 4G compatible SIM card.
When I go into settings, all I get is the option for 2G/3G auto, and 3G only. No option for 4G/LTE.
I can type in *#*#4636#*#* and get into settings and enable LTE, and then I get the LTE icon at the top and I can go online. However, when I go back into Mobile Data settings, as soon as the screen opens, my internet drops and it reverts to "H" or "3G" at the top. Once again, when I click the option, it only display 2G/3G or 3G only.
How can I activate the option in my OS so it shows up here?
I am running Android Revolution (ARHD) version 92.
Thanks.

Any way to set data to use LTE only (and not 2G/3G)?

I'm missing the option to set my device to 4G only. Under "Settings" -> "Network & internet" -> "Mobile network" -> "Preferred network type" I can switch only between "2G/3G/4G" and "2G/3G". I miss further options and especially to set it on "4G" or LTE only. Because my network provider is pretty bad at 3G but quite good at 4G, even when 3G signal is much stronger and 4G signal is weak.
I don't care if I can't take voice calls in this mode.
Edit: I see there are apps on the store to do this. Though would be great to do it within the ROM.

My old phone did, when LTE signal was weak (but still available), and I assume, any other phone will do so as well. But data was much more reliable within 4G than 3G, even when signal was weak.
I play a gps-based online multiplayer game and whenever someone complained about bad data, I hinted to set their phone to LTE only.

4G+ Means LTE-Advanced aka True 4G, and it is faster than 4G. The only difference is the maximium theoretical speed, bandwidth and minimium latency you can get. 4G can reach speeds up to 100Mbit/s, while the 4G+ (LTE-A) can reach up to or over 1GBit/s, with less than a few milliseconds of latency.
