I followed the instructions like another thread comment said to do but for some reason I couldn't get it to work still but after playing around I was able to get it working.
---- Instructions for enabling: (thanks eyecon82) ----
1. dial ##3282#
2. then click edit (need MSL code) (I used SPCUtility.apk as nothing else worked on my S5)
3. then click LTE
4. It will show LTE ( also known as Band 25), Band 3, Band 26, Band 41 ( I unchecked marked all of these but the LTE option leave that check marked to on)
5. Disable all bands leave LTE check mark to say on.
6. Go to the main directory by hitting back key and choose More at the bottom
7. Choose HDR/1X Selection and choose LTE only Mode. Click OK to save
8. You can either reboot or I just turn on airplane mode and turn it back off to reset the connection.
9. LTE should be working like mine did. But you will not get phone calls until you turn back on the HDR/1X Selection to LTE + CDMA +EVDO Mode but you will get text messages fine.
The items that are underlined in Red are the stuff i added.
---- To tell what Band on: ----
1. ##debug#
2. enter passcode 777468
3. go to LTE engineering menu
I hope this helps because all the other stuff I read would not work for my Galaxy S5 I just bought.
Thanks
One more thing
I read on here http://s4gru.com/index.php?/blog/1/...-due-to-circuit-switched-fallback-technology/
that this problem should be fixed soon but if you need LTE now here it is.

Thanks for the info. However, I think its crazy to want to set it up for LTE when you cannot receive phone calls especially since this is you know, is a phone. Calling Sprint and talking about this situation is useless. They all say nothing is wrong and its the device. I'm really pissed off about this but I enjoy the phone. This will probably be the last Sprint phone I will get.

I use it at night or in places that I need fast internet and when I know I dont need a phone for a bit which is why I have voicemail I just switch over to LTE for a bit and then back...but yes it sucks for now until they upgrade the tower over here with the feature needed to use LTE spark devices.
Im loyal to sprint but its becoming more and more hard to be loyal.
Probably just your area, not the phone.
Your area may have LTE but if it doesn't have the circuit fall back enabled yet (tri-band phones) can't drop the data to allow a call and thus they force you to remain on 3G only.
Once your area has everything done it should get better.
I have similar situation that KILLS my battery at home but in every other part of town it all works great :/

Found out from reading the Sprint forums (https://community.sprint.com/baw/thread/157300?start=0&tstart=0), that this is likely not caused by the circuit fallback, but incomplete rollouts of Spark technology. Disabling the new Spark bands has helped me keep a stable LTE connection. Once the Spark rollout is complete in my area, and Band 26 can support both Voice and Data, I'll re-enable it the new spark bands.

Which bands did you disable? Also, are you able to get voice calls when you LTE?
Im a bit frustrated be the place I spend most of my time (where I used to get LTE fine with my S3) I no longer get LTE and its super slow 3g. Calling sprint didn't help, they just say to wait until cell tower updates are finished in the next 6 months.
If I disable the Spart bands, will I be able to keep LTE and voice? Thanks

I disabled bands 26 and 41. This forces the phone to use the default sprint LTE band. It receives voice calls just fine.

LTE works fine because it defaults to the standard LTE band.

Read the sprint link. Incomplete rollout of spark, in particular on band 26 can cause the issue of not being able to switch between 4G and 3G and back.
Hello,
I recently purchased a Samsung Note 3 SM-900V. As a previous Note 1 user I wanted to upgrade my device as I really enjoyed my Note 1.
I use a carrier called Simple Mobile, they are a sub carrier to T-Mobile. Meaning of course, that they use the T-Mobile network.
The problem is this: Simple Mobile (T-Mobile) prefers to use 3g/4g/LTE connections for their data and texting services. Meanwhile, Verizon uses H+ connections primarily, or as I understand it. This difference in signal, from what I can understand through a few days worth of research and combing forums, is the leading reason why my N900V wont upload/download pics, poor signal, etc. etc. DO bear in mind that Verizon software on this device forces the use of the H+ network though it does use 3G as well. Just never 4G or better.
From what I understand it is this H+ preference that the phone has me locked into that is causing my problems. It would seem that this device is capable of using 4G LTE and from my research, being able to use Band 4 would fix most all of my issues.
The major problems itemized are as follows:
Error message "This SIM is from an unknown source"
Unable to send/receive MMS texts
Reduced signal strength when compared to using my same SIM in my Note 1 side by side in pinpoint locations
Complete loss of signal in areas where SIM/Note 1 device had very good signal
As such, from what I can understand, if this device could access Band 4 then it would communicate with the Simple Mobile/T-Mobile network and erase the Sim card error message, send MMS and receive, and finally.... match the coverage I was accustomed to before I used this SIM on this device.
I've have considered a few solutions to include rooting the note 3 so I can enable 4G LTE, installing a factory version of KK 4.4.2 without the Verizon Brand and its bloatware forcing me to use H+ and as a final resort, selling the device (which I do not want to do). Though none of these options seem possible considering I'm using a N900V. At least not without bricking it.
Each time I think I've found a solution, there's a compatibility issue with my device, the software/firmware version, the chipset, etc, etc.
I've attached a screenshot that details some of the specs of this particular phone.
Any options or help would be appreciated.
Welcome Wallace
ok, thanks
so basically, you bought a verizon phone and using a sim card of another network.
Have you tried ringing verizon and asking them about this problem.
I have installed roms on uk version samsung S and S2.
What we now need to know is if American version supports Band 4 at all....I hope someone answers your questions here...
Admins/Moderators here should be able to give us a good answer.
Did you try...

It is on global now and still only fluctuates between 3G and H+. Never 4G or LTE.
I've read about this issue from others but the fix was to root and then switch the phone to use band 4 by default.

Did you try "3g/4g/lte" instead of global? Band 4 is the latest and greatest and not available everywhere yet. The normal band you should see is band 13 (at least for me). There is a good thread in the "General" section on "Service Modes" you should look at.

That may be true. I'm not sure and I cant validate it. However, it would seem from what I am reading that I need to switch it to B4.
I haven't rooted it and still looking for a way to root a KK 4.4.2 N900V. Once I have access to that menu I can test whether these methods from other threads and sites are accurate.
I'm not saying you are wrong by the way but under the current settings my phone doesn't talk to my network and incurs an entire host of other problems.

If you are on the NC4 OTA then use towelroot. Do a search for "KK root" and you will find all the methods available for all versions.

I have switched from global to GSM under network settings. Going to see how that works. I get poor service with global setting but I do get service. Under CDMA I get zero signal. Even though I had 3 bars a second ago under global.
I'll let it sit on GSM for a few hours and see how that works.

I read the entire article a few times just to see what it had to say about my problem. Unfortunately, it does state that I must be rooted to even proceed with most steps.
Back to square one. I need to root it, however, the threads on here that refer to rooting with the N900V and KK 4.4.2 in mind say that there is not any way to root this device with this operating system.

Hey there,
So i followed the instructions for towel root, both versions, and I dont think the change took.
I installed ES File Explorer to make some changes from the advice of another thread and those changes cant be made because I cant find the file or the directory. Even after enabling options for root and display hidden files.
So, even after installing Towel Root, when I go to access the service menu using any of the codes I get no action whatsoever.
Im still in the same boat as well as far as not finding a proper KK 4.4.2 root file/method for N900V that does not follow itself with threads saying how it doesnt work at all.
Is there another way to root that I'm not considering or havent found yet?
Thanks for listening.
Try this:
-Dial *#27663368378#
-UE settings & info
-Settings
-Protocol
-Nas
-Network control
-Pref mode set
-Choose GSM_WCDMA_LTE_ONLY
You may need to reboot. This worked for me on NC2 with a MetroPCS sim. If it fails then double check your APN. You may also try to factory reset the phone with your Sim inside. When you do a clean install you get more options under Network Mode in settings.
I Have a brand new SIM from WIND mobile in Ontario that came in another phone. I have this Nexus 4 kicking around so I popped in the WIND sim, but it does not connect. When I go to search for mobile networks in settings, it finds all the non AWS carriers (including the 'WIND away' network) but does not show Wind 3G (this is what the correct network lists as on my phone supplied by them). I have played around a bit in the *#*#4636#*#* menu, but nothing seems to make it work. Is the AWS band disabled in some Nexus 4s, and is there a way to enable it?
Welcome to XDA
Okay, first of all to avoid duplicate threads please use the search function of XDA to find your answer, or do a little Googling...
Anyways to answer you question, the AWS band of the Nexus 4 is disabled by Google to lower costs. That may sound crazy, but the story goes something like this:
If you didn't already know, The Nexus 4 is based off of the LG Optimus G, and has a lot of the same insides...
The same board was used for the nexus 4 and Optimus G, and on some of the G models they had LTE on band 4 and 17.
The nexus 4 never went through the FCC for LTE so Google disabled it because it wasn't worth the trouble of supporting 1 band.
Now, your answer: Depending on the Android Version, it maybe as simple as tinkering with the Info menu you were in. (4.2.1)
Newer versions were harder to enable LTE
You need to figure out what you need to do depending on the newer version.
You may need something as simple as an older radio
You might need to unlock your phone's boot loader, (which requires a factory reset), or maybe even have to flash a custom recovery (like CWM or TWRP) and custom rom.
It would really help I knew more info about the device likel what Android version,if its rooted, or has an unlocked bootloader,etc.
If you don't know what any of this means DON'T WORRY, there is an entire community of people willing to help
Sorry I should have gone into more detail. I have done the various tricks to try to enable LTE, but is that the same as enabling the AWS network? I was under the impression from the WIND folks that the Nexus4 worked for them stock.
As for the firmware version, I have tried on 4.2, 4.2.2, KitKat (4.4 I think?). I have tried after flashing the stock roms of each of these versions as well as after rooting. I have also tried flashing different radio versions to no success.
I should also mention that under the "4636" menus I have tried to click "select radio band" from the menu, but this just crashes the process and goes back to the first menu.
So does no LTE mean no AWS?
Hmmm...
First of all, NEVER click Select Radio Band, like you said, it crashes both the menu and resets your connection. Bug? Unfinished feature? No one knows.
You are supposed to click on GSM/LTE button instead of WCDMA preferred.
If that sticks then you might be done on (4.2.1)
If on higher version, then get the older .33 or .27 radio or a hybrid radio
AWS is the band the nexus 4 has unofficial support for, so its actually the opposite:
No AWS=No LTE
So try getting 4.2.1 via factory images and try getting that working okay (WCDMA→GSM/LTE)?
If not then tell me
How about 4.2 (JOP40C)? I have that currently but I can go back and get 4.2.1 if necessary.
And just to put the AWS/LTE bit to rest, can I have (on this or any other phone) AWS without LTE, or are they synonymous?
I am playing with it right now without the sim becaue it is busy in the other phone. When I switch to GSM/LTE AUTO, I find AT&T as well as the big three Canadian networks, but still don't see WIND. I did not see the AT&T on WCDMA, but its spotty near the border here anyways.

Sorry for the late reply but,
In 4.2 all you have to do is switch to GSM/LTE and switch to correct APN's in the phone settings
You can AWS on 3G as far as I know but it won't make a difference...
The only reason we are using AWS band for LTE is because its the only one the Nexus 4 can see.
As for the last paragraph what do you mean you cant see WIND? What do you mean by "seeing"?
Can you clarify?

Could you try this small app (should trigger the radio band select menu) to see what options do you have?
https://play.google.com/store/apps/details?id=de.mangelow.network
For the Wind Mobile AWS, you will need the WCDMA option. This is what Wind Mobile use, not LTE.
If you will be able to select the WCDMA option and still no Wind 3G/HSPA, then we will tinker with the APN settings.

By 'seeing' I mean when I go to the network selection / search function in settings. When I click to search for network providers, I do not see WIND3G as an option (or any WIND branded network). On the phone they provided me, when I search for networks I have several options that are labelled as WIND. If I recall correctly, I think I have about 12 choices between various providers, whereas with the Nexus 4 I just show three selections.
@DupleX01, Thanks. I will give that a shot when I get a few minutes to play with this at home. It has been a couple of weeks since I have worked with the Nexus.

It's a slow day at work, so I am back on this. I have tried setting the radio to WCDMA only, but this does not make a difference. The only network I can see with the SIM in is "WIND away", which I believe is Rogers. So I am on roaming. Should I flash a different radio to the phone? Anybody got suggestions on which radio is the best version for use on WIND?
With the SIM in, the APN settings are already correct for WIND, but I am not finding their network.
Also just for kicks I flashed kitkat (stock) again, including the radio that comes with the ZIP. No changes in network availability.. Gonna leave it on this for now unless someone suggests that it might be better to revert to 4.2.1 or another version.

Based on your findings, I would say everything is alright on hardware side (APN is good, radio ok for WCDMA). So, it could be a glitch with Wind micro sim card. Still bonded to the previous phone IMEI what not. Make sure you now the serial of the micro sim, your imei of the new phone and give them (Wind Mobile tech support) a call.

Note: The title of this guide is Enabling LTE bands, but actually, it's for LTE and for HSDPA bands.
This is something near and dear to me, as I travel the world somewhat and really prefer to have only one phone.
I spent all day figuring out how to add more LTE bands to this phone (I have a bootloader unlocked H815, European version, so please understand that it may not work with other versions, and simply can't even be attempted until you can root it.)
The model I own comes with the following bands:
2G bands GSM 850 / 900 / 1800 / 1900
3G bands HSDPA 850 / 900 / 1900 / 2100
4G bands LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 17(700), 20(800), 28(700)
I noticed, however, in the hidden testing menu (277634#*#, Field Test, Modem Settings, Network Mode), the following extra bands, none of which worked:
WCDMA 800, WCDMA AWS (1700/2100)
Along with the following extra LTE bands(277634#*#, Field Test, Modem Settings, LTE Band Selection), again, none of which worked:
Band 12, 13, 25, 29, 40
The result?
Having enabled all of the LTE bands available in the testing menu, I was able to add WCDMA 800 and AWS bands, along with LTE band 40. Unfortunately at this time, Bands 12, 13, 25, and 29 do not work, even if enabled. However, a T-Mobile radio file might help for band 12 if it's a radio issue, or it could be a hardware difference in which case there's nothing we can do. I really don't know until I can test with it. I'm happy about the extra bands, though, because in the US I use T-Mobile, so AWS helps, and in Japan, band 800 is used. Maybe I'll use 40 if I go to China some time.
So how to actually do this?
Step 1: Unlock bootloader and root. You can find out how to do that in other threads.
Step 2: Install the LG USB Drivers. It comes with the LG PC Software.
Step 3: Download CDMAtool from here: http://cdmatool.com/ A free trial works fine for this.
Step 4: Make sure you have adb, and connect your G4 to your PC. In an adb shell, execute the following:
su
echo 1 > /sys/devices/platform/lg_diag_cmd/diag_enable
Step 5: Unplug and re-plug your USB cable. Your phone is now in diag mode (although you wouldn't know any better because you don't get any special device names in Device Manager.)
Step 6: Open DFS which you downloaded from CDMAtool.com Deal with making an account, etc. as you have to get into the software. Close the account window and the actual software will launch.
Step 7: Double click your device to put a checkmark by it in DFS.
Step 8: Click the Band tab. Choose RF BC Config at the bottom. Then, choose read.
Step 9: Make sure your bands are displayed. Check the extra bands you want to add. I recommend against enabling bands other than those mentioned in this thread, but you can try at your own risk (in fact, I'd be interested to see if any work!)
Step 10: Click Write.
Step 11: Click the LTE tab. Click Read. Check the bands you want to add, click write. Then, choose LTE BC Config DIV LTE #6829 at the bottom and repeat the process again there.
Step 12: Sometimes the write doesn't go through, and I have no idea why, but I found it helps to play with your phone for five minutes after writing. Also, I found that even if you're not changing bands, it's somehow necessary to flash HSDPA and LTE bands both in one go before restarting the phone. Otherwise strange things happened like losing bands. I was able to get them back though by re-flashing.
Step 13: Reboot your phone and pray.
Step 14: Go into the hidden menu and test the new bands. If they work, you will see SUCCESS when you press them in the test menu. (277634#*#, Field Test, Modem Settings, Network Mode/LTE Band Selection)
I hope this is useful to any other globetrotters!
That's gr8 tip!
Bands are tied to the hardware. Software tweaking won't add them. Not unless they're already part of the hardware, but disabled and hidden by LG for some reason. But that's doubtful.
It might tell you they've been added, but I highly doubt they'll actually work. But I'm no expert so LG may have done something weird here.
So. I have a T MOUS HTC One M8. We have a Qualcomm LTE radio that apparently has access to Band 12 which is TMOUS new 700 MHZ spectrum.
I am currently on band 4 through LTE discovery. Is there any method for adding Band 12 to this version of the HTC One M8.
What aspect of this guide can be used to add to the HTC One M8 T-Mobile Version Band 12?

The added bands do work (depending on the band) so in this phone's case, two new hsdpa bands and one new LTE band were add-able.
I was able to personally confirm HSDPA AWS working on T-Mobile US. The other two added ones I can also confirm because they are scanning on that frequency when using the LTE Band test menu, although there is no local network to attach to.
With other phones even more drastic success stories exist:
http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
But in this phone's case, the hardware supported more bands than were enabled, so enabling them was possible. I haven't been able to get particularly Band 12 working, probably because of either hardware or radio file, but it was nice to enable some other bands and see them work.
@the_scotsman the hardware in this case is able to do it normally, but LG has to pay a fee to unlock these bands which is why they're normally locked via firmware.

I worked with Qualcomm chips before so the software setting enables the bands in software. the_scotsman is correct in that if there are no antennae on the phone for those bands then the OP's guide will not do anything. Seems that the OP has confirmed that for bands like HSPA Band 4 the antenna is present. It could also be that the LG didn't calibrate performance of the phone on those new bands for this model. That all depends on how they are manufacturing this phone which we will never know.
Anyone else tried this out? I use the Canadian equivalent of T-mobile so I would need HSPA Band 4. I'm wondering if I should buy the international version and get the unlocked bootloader or buy the locked bootloader version for Canada.

I actually want to know the same. I need HSPA B4 (AWS). I want to buy LG G4 H15 version. If I can enable HSPA AWS band, then im on board to get this phone!
Not particularly useful as this requires root

Yes but the H815 from Europe can be rooted easily so this is an option if you bought this model of the G4.

I ended up with the Canadian version in the end. Turns out the H812 has all the canadian bands turned on and once you unlock the device you can go from a carrier who only uses HSPA(AWS) to one that uses LTE without any rooting or enabling bands. Seems at least for the Canadian version all the bands for all Canadian carriers was turned on.

Were you in a confirmed Band 12 area? Or did it say "fail" and not even scan it?
If he had a H811 model, Band 12 is enabled.. I had Band 12 LTE when I was in the US in the Maryland/DC Area..
Sorry for late reply. It said 'fail' and didn't scan. This is European H815. It's now bricked because I played with it too much.
Has anyone tried this on the VS986? It seems that band 2 is locked even though it's listed as a supported band. When using a T-Mobile SIM I only get LTE in band 4 areas and not band 2/12.

Seeing as how the first prerequisite is an unlocked BL, I don't think this would work :/

On the G3 you were able to use the HiddenMenu via a root-capable shortcut app, but now we can't access it as we get a FC. I skimmed this and didn't see the unlocked BL requirement, my bad!
@duraaraa How do you know if they're "working" exactly?
In the field test menu on my rooted H818P under LTE Band Selection, I have listed 1,2,3,4,5,7,8,12,13,17,20,25,28,29,40, half of which say "FAIL" when you tap on them, including band 28, which is LTE700 in Australia (FDD)...yet this phones' specs indicate this works...so I'm a little baffled?!
I don't have an unlocked bootloader (obviously), so I guess that means I'm no hope of performing anything successful in terms of accessing other bands?

Well, they went from saying "FAIL" when chosen, to trying to find a signal. Not being in a Band 40 country, I can't be sure, of course, but my assumption is, since it became the same as all other bands which were to be supported by the phone, by not saying "FAIL," that it would work.
However, if you are sure that band 28 is working on your phone, and it still says FAIL, this opens the door to having more working than I thought, so it's certainly interesting! Sadly, as I mentioned before, my phone is currently unrecoverably bricked, so I have to wait for some kind of way out of the brick to continue this testing. Ironically, I'm going to China in August so I could have tested band 40

The problem I've discovered is band 28 (700mhz FDD) SHOULD be working on the H818P be default/stock....yet after root and accessing hidden menu, still says "FAIL"
Thats a huge worry, as the LG sticker with IMEI (etc) indicates it should work on that band!
Really hope unlocked bootloader is coming soon for H818P. Confirmed in the DUAL SIM thread, that phone *DOES* support 700Mhz bandwith...but for countries that probably have 100% of their population that DO NOT even own or sell this phone. Band 17 is supported, not Band 28 (densely populated countrieslike Aus, NZ etc). @duraaraa
Really need to unlock band 28!

My Redmi Note 7 arrived yesterday from Banggood and things seem to be working well, except that I don't seem to be getting LTE. I'm in Canada and need band 4 to get LTE on Koodo.
The description on the banggood page included band 4. The model is M1901F7G, and the specs the I find everywhere say that it supports band 4. The FCC ID is 2AFZZ-RMSF7G, and the test reports that I found include band 4. But when I turn off my Wifi all I see is a great big H+.
Is there a way on the phone to check what bands it actually supports (without root)?
Have you checked the APN of the phone is correct? I bought a Redmi 5A for my father and it couldn't get 4G because of that.
I checked and it all matches the settings found here:
https://www.koodomobile.com/help/setting-data-your-non-koodo-phone
Should I try switching SIM slots? I'm currently using SIM 2 so it doesn't block the (currently unused) microSD slot.
Update: Rebooting the phone gave me 4G access. I realized that I hadn't rebooted since installing the SIM card.
My question still stands though. Is there a way to check from the phone which LTE bands are supported? It would be useful to know when I next travel.
Checking for all supported bands is only possible on rooted phones, afaik.
The currently used band is shown by apps like Netmonitor: https://play.google.com/store/apps/details?id=com.parizene.netmonitor
