How to enable LTE

Hi
I ve moved from a S4 to Note 4 but cant see in mobile network the option 4G, just automatic 3G/2G and 2G. How can I enable it?

First, it's a Note 3, Note 4 yet ^^ (<- I like the word play here ^^ "not for yet" was not my initial intention ^^)
You might have the Exynos version that is not 4G compliant.
Check the version of your phone in settings : is it SM 9000 ? Or SM 9005 ?

SM9005. The telco company (Movistar) says they will launch a new ROM in a few weeks and samsung too. With S4 we could activate L4 with Service Mode menu (*#0011#) but doesnt work for Note 3....

I thought that option on the S4 was just to activate DC-HSPDA, don't think the option was anything to do with the actual bands associated with 4G "LTE".
May not work as DC may already be enabled.

With my S4 and using the same SIM card and can see the option "4G/3G/2G automatic" and conntects to LTE, with speeds 40/15. But with the Note 3 and same SIM that option is missing and only connect to 3G

I don't have that issue in my note 3 (N9005)

For those who cant see the option 4G you can download the app viaero. I ve tried many switchers but this app really works for Galaxy note 3

Hola!
So you have LTE with Movistar in Madrid, and it shows the "LTE" info?
Just curious as I have Tuenti (I know they don't have 4G yet), and next week I will be back to Ireland...
Thank you for your post, gracias!

I flashed the Polish 4.4.2, root and I have a slightly different problem: on my SM-N9005 the LTE option is available and selected but I cannot connect to the carrier's LTE network. Other phones can connect to the LTE network with this same sim card.
I think that although LTE is enabled the modem may not be setup as per Samsung new region blocking policies...
Any idea what to do to enable LTE?

No Lte speeds
Good day, good people, I recently purchased GN3 here in Freeport, Bahamas.
The phone came with these specs:
Product Code: TTT
PDA: N900W8UBUBMJ4
CSC: N900W8UUBBMJ2
MODEM: N900W8UBUBMJ3.... with no Lte option available in the network toggle.
After downloading the OTA update my Note then had these specs:
Product Code: TTT
PDA: N900W8UBUBMJ4
CSC: N900W8UUBBML1
MODEM: N900W8UBUBMJ3.... after which the lte option was now in place. (pics to follow)
So here's the problem, my network provider has confirmed that its lte network operates on 700MHz Class 17, I've connected with my AT&T S2 Skyrocket flawlessly, but my note seems unable to connect with the network despite all the of the correct settings being in place.
Is there something with the modem settings that I may not be aware of that could be preventing this, and is a way to change or modify it in order to get lte service? Or is there a posibilty that I have a defective unit or even a defective sim card? Thanx for you help.

no LTE icon after 4.4.2 update

Hello people
Im posting this here as I havent managed to find a solution yet.
I have a German T-mobile 16GB d802, only the device was purchased and using it in Greece.
When I was using 4.2.2 everything was perfectly fine concerning LTE with my mobile provider.
After flashing 4.4.2, I noticed that I data traffic was not working anymore. After searching I found that my APN settings were gone, so I manually inserted them.
Following that, I noticed that when I am on LTE network and have data traffic enabled, I don't see the LTE icon on the top right corner on top of the signal sign anymore. The data traffic is working though, so it seems to be a missing icon for some reason.
In 3g/HSPA and Edge I see the relevant signs, the only problem is when using LTE
A friend of mine who has the exact same version of the phone has got the exact same issue on a different cellphone operator. So its not related to the network.
I reported this to LG using the local site, but got the reply that I haven't bought the phone from the local market and they don't know the changes made from tmobile..
On tmobile website you cannot report an issue unless you have a german tmobile subscription or for business issues, so I have sent them my problem stating Im contacting them for business related reasons
Anyone else got the same issue? Anyone using German T-mobile? Anyone who has any ideas?

update:
Got a reply from T-mobile Germany that they need to have the phone in their hands in order to troubleshoot and they cannot help me

In your dialer, enter: *#*#4636#*#*
Then go to Phone Info, scroll down and set the drop down to LTE/GSM/WCDMA or something similar with LTE at the start.
See if that works...
This is something you have to do each time you boot though.

What you propose is valid if you cannot enable LTE.
I dont have that problem. I have the option to enable LTE.
The problem is that after my phone connects to LTE I dont see the LTE or 4G icon on the top right side next to the signal sign.
But LTE works perfectly fine, I managed to make a speed test to almost 54Mbps yesterday
http://www.speedtest.net/my-result/a/785031726
So it not the regular issue that most people have with LTE being disabled, my issue is that the icon is missing
Thanks for replying though

In addition i also found this:
Dial 3845#*802# on LG-G2 key pad,
then the secret menu will come up...
Then: 1. Go to LTE-Only
2. Modem Settings
3. RAT Selection
4. Select GSM / WCDMA / LTE auto
But when i select LTE-Only a popup comes up saying "not supported" altough LTE works fine appart from the missing icon.

They must have made some customization in the icon that you dont get unless you download the tmobile stuff when you connect the phone at germany,
Do you by any chance speak German so you report the issue as well? Maybe if they get many tickets they will fix ut

[Q] N900V KK4.4.2 Can't enable 4G LTE

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...

I've got the same phone and I was able to 4G LTE to run by changing the Network Mode setting to Global.
Settings/More Settings/Mobile Networks/Network Mode.
It may not switch immediately but will eventually switch.

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.

hi,
You have to contact you service provider and ask them to enable it for your sim/device. Only then should you see it in your options
.Also note it has nothing to do with root.
Take into account that service provider offers LTE/4G and your device is LTE capable and you are in a LTE/4G reception area etc etc
good luck

My provider told me after few day samsung gives us little update that gives in our country that option

Hey bro, go to settings/more networks/mobile networks/network mode... see if you have one option with LTE/WCDMA/GSM, if you don't have it, your device is probably a clone, because 910c has the 4G option, it doesn't depends of your SIM card or 4g on your region.

Not necessarily. It could be disabled within firmware. Couple years back I had lte ready Note 2. Only after tmobile network was ready for lte OTA update enabled lte option in settings.

Note fe won't get 4g lte. 3g only.

Hi there! My note fe can only get 3g. My model is n935k and I am a current an ATT user. I tried to force the phone to LTE only but when I did that, the phone was totally out of service. No network and no call service. I thought note fe LTE band will be worldwide, so is there any setting that I missed?

1. make sure your APN is ATT Nextgenphone (should have been auto-configured when you booted phone the first time) 2. Try reseting your network settings (this will remove bluetooth and wifi settings) settings->general management->reset->reset network settings and/or 3.Call ATT and make sure your account is (still) provisioned for LTE. i have the same model as you do and have no problem getting LTE service. picture below shows i'm connecting to LTE Bands 2, 4, 5 & 17.

I reset the network setting and still doesn't work. The apn is nextgenphone.

fellow note fe user in north america here.
no issue with lte. but @cortez.i what LTE log app is that? and also how did you customize your icons on the status bar?

LTE Discovery from the play store... Substratum theme for Samsung (Swift Dark) for icons.

And I have tried some app like force phone to switch to lte. After forcing the phone to lte, the phone signal is lost and become emergency call only.

I had the same exact problem and I'm also on AT&T. Restarting the phone fixed it, at least for now.

if you haven't done this already, consider trying another SIM. I'd also post screen shots of your configurations; could be something we've missed in our attempts to help you resolve your issues.
