1) Go to Phone, just enter following command,
*#*#4636#*#* (no need to press Green Dial Button after this).
2) Once you enter last *, Testing menu will appear. From that menu,select "Phone Information"
3) Scoll down little and you will see "Set Preferred network type". There is dropdown at this location which shows all the networks.
Just note,This is testing menu. It will show all the options like CDMA/WCDMA, GSM, LTE etc. It does not mean that all the networks are supported.
Just insert LTE sim and change option of preferred network from above list to LTE only and check if that works.

Officially it supports 850, 900 bands. But I am wondering if the bands are only controlled software side seeing that the antennas and hardware seem to be streamlined across all versions.

On the box it says:
LG-D802
LTE 2100/1800/2600/900/800
6GB
BLACK BLACK

Thank you for the test menu you solved my problem I just bought the d802 would not work on my 4g sim in uk changed to lte and all good thanks.

Sorry to bring this one back form the dead but the original question doesn't appear to be answered to me...?
I am on Three in the UK and they are rolling out 4G on 800Mhz and 1800Mhz. Complete noob here, but from what I have read 800Mhz has greater range and building penetration (at the expense of some speed), which is great. Except that the G2 doesn't actually support 800Mhz LTE, or does it?

I'm on Tesco mobile (O2) and have the 32GB D802, and my 4G wasn't working in central Manchester (could only get HSDPA) Just followed your instructions and boom, 4G instantly with full signal inside 16mbps on speed test

same here with tesco, set the above and worked fine, but after restart just defaults back to gsm/wcdma auto as preferred and need to go through the steps again to achieve 4g. Anyway to save this as preferred?

I found and downloaded the free app 4G LTE Switch from the play store to help with this.
While it doesn't solve the problem of having to manually select LTE after each reboot, it saves you from having to dial the code yourself. Instead, just launch the app and it takes you right to those settings. I find it very useful and time saving! :good:

cheers for the heads up, i'll give it a bash, still find it very strange that a 4G phone doesn't come with an easier way to actually activate 4G.

No problem man. I didn't give up searching and actually followed this thread, where it says "No 4G/LTE?" and tried putting my networks actualy LTE band (17) in there instead of 11 and 13. While it now gived the option of selectiong LTE in the dropdown menu of preferred networks, for some stupid reason, the phone STILL doesn't save the setting and you still have to go back to the menu again after a restart to enable LTE.
While it is even easier than the method I said earlier, still frustrating that even after selecting it in the menu, that it still defaults back to GCM/CDMA!
There just HAS to be a way to make this stick. Any devs out there who could look into this further???

Hello,
I am from Portugal, so your mobile could say something rather different. But in essence is all the same.
My version is the D802, International model, just like yours.
1.st step - Provider:
The provider part is always the first to be deal with.
Make sure you go to your operator and ask to enable your SIM-card to have access to LTE.
2.nd step - Equipment:
Go to Definitions -> "Network" tab -> "Sharing connecting & Network" on the bottom -> "Mobile Network" third from last ->
a) Make sure that "Enable Data" is checked;
b) Go to "Network Mode" and choose the option: "GSM (2G) / WCDMA (3G) / LTE (4G) auto".
This way you will always have automatic access to the best network available.
All the people who choose the 4G/LTE only option should check this mode, so you can access 3G when 4G is not available, instead of having no connecting.
Any doubt you have, just ask!
Best regards.

Step 2 in bold, that's not an option. 3 options are
1. GSM / WCDMA auto
2. WCDMA only
3. GSM only
However when using the 4G switcher app you can change it to GSM (2G) / WCDMA (3G) / LTE (4G) auto and it works fine, but on reboot just defaults back to GSM / WCDMA auto.

Our D802 supports 1800 Mhz and 2600 Mhz frequencies for sure.
But to get the LTE toggle to show up in the network selection menu, we need to insert a LTE capable sim or usim. Tried and tested and not a here say.
If you do not get LTE option in network selection then your sim is not LTE capable. Simple.

Well the sim I have is LTE capable, When I change the options with the 4G switcher app I instantly get the 4G signal and can get speeds of near 50mbps.

The option in my phone is:
"GSM (2G) / WCDMA (3G) / LTE (4G) auto"
All this information at one option.
So the phone can choose the highest band level.
This is a problem with your ROM or a problem with your SIM.
And, as I said in my first post, go always first to your provider and ask him form help.
Making sure the SIM part is enabled and fully accessible.
The bands are not important here.
That is because, if you bought your smartphone in the UK, LG made available the D802 model to make your smartphone antenna frequencies correspond to those available at your country.
This will matter if you want to achieve maximum speed of 150Mbps.
But if you want just the regular user experience, you sure have access to LTE network.
In wikipedia (I could not find a good source, as GSMArena make no reference on the version D802)
Wikipedia -> LG G2 -> Specifications
D802 supports 4G/LTE bands:
800, 900, 1800, 2100, 2600
And here you can see the bands of your provider/network:
Wikipedia -> List of LTE networks -> Europe
EE: 1800, 2600
Hutchison 3: 800, 1800
O2: 800
UK Broadband: 3500, 3600
Vodafone: 800
This is wikipedia information, so take this with a pinch of salt, and search for a better source.

Its a UK sim free handset, and i'm on tesco (which is O2).
Sim card is fine as tested in another 4G phone and defaults to 4G as it should after collecting the APN settings from the network. Checked the APN and both the exact same compared to the one the LG G2 is using.
I'm using stock rom and this happened initially on JB, then updated to KK, factory reset, and still the same, then updated last week, still the same.
From reading this thread looks like i'm not the only one.

Wikipedia, and other websites, say O2 only acquired 800MHz band for LTE.
And LG G2 D802 only supports:
850 (band 5), 900 (band 8), 1800 (band 3), 2100 (band 1), 2600 (band 7) MHz.
I saw this at PhoneArena, GSMArena and ATGSM.
This brings a problem for people which their carrier only emits LTE at 800MHz, when not supported by come smartphones.
But I recommend you all to ask LG about the frequencies supported by the LG G2 D802 version, and ask your network carrer/ provider for LTE frequencies.
That way you will be absolutely sure about its compatibility or not.

wikipedia is saying....LTE band support 800/900/1800/2100/2600, however tesco (o2) are definitely on 800mhz, so must be something to do with LG so it will no doubt be them who has to answer the question, and never do anything about it.

[Q] [N9002] Galaxy Note 3 Duos Enable LTE Band 4 from Service Menu, Does this work??

Hi All,
I stumbled across this as I am currently not in the US to test this out. Could someone see if this actually works? It supposedly enables the LTE band 4 on this phone even though specs say that there's not LTE on it. I was hoping it would be there as it has the same hardware as the N9005.
According to the Service Mode on the N9002, you can enable VZW LTE Band 4. I believe T-Mobile also uses this band for their LTE. I enabled it for me, but I am currently in an area that I can't test it. I posted screenshots of the Service Mode, and a video capture going into the menu.
How to enter service mode:
1. At phone dialer, dial *#0011#.
2. At the service mode, hit the menu key, and select back. It looks like it did nothing, but go to the next step.
3. Hit the menu key again and select "Key Input" and type "Q". It looks like it did nothing, but go to the next step.
4. Hit the menu key again and select "Key Input" and type "0000" (zeros).
5. Wait until you see "Main Menu"
6. Select [3] LTE
7. Select [2] LTE RF
8. Select [1] VZW LTE B4 on/off
9. Select B4 Enable(). It should now have an asterik in the parenthesis.
10. Reboot phone.
Here's a screen capture on how to enable it.

I tried this on the N9002; Dual Sim variant.
If you have a different version, this might be better for you as I didn't have a custom kernel for mine.
http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059

I just ran the process and my phone rebooted without problems (N9005). Now, I just have to get an LTE sim card for a network that runs on those bands (I'll try to do it on this weekend and confirm if it worked).

We have the same phone, sorry I didn't mention that. I'm running a custom rom, witch I guess is only an advantage... But you enabled lte band 4 and in Sweden my carrier has band 3. I checked the other "how to" but it seems a little bit complicated and I'm a little bit worried about messing things up.

I don't have a way to try it right now(my n9002 is at a repair shop atm), but would you mind trying this? the article says to modify the /data/property/ persist.radio.lteon file to "true" and “LTE/WCDMA/GSM (auto connect)” should show up as a selection of network preference. Can you let me know what your results are when you try it?
//smokeys.wordpress.com/2014/04/06/how-to-enable-lte4g-on-samsung-galaxy-note-3-sm-n9005/

Sorry for the long wait, wife had phone. The file was already set to true. No lte option in Network Mode menu.

Thanks for trying. I realized that my bootloader is locked so I can't flash a permissive kernel. I think that would've been able to do it I think... oh well

My SM-N9005 was crahed 4G/LTE when i test that... even if I disable, my 4G not working now
How I can deblock that ?

I try this and I still have only 3G/H+ on n9002.
Probably Samsung does not include LTE Modem

Adding LTE Band to MOTO G5 PLUS (XT1686)

I bought Moto G5 Plus (XT1686) from India and now I have moved to USA.
In USA i am using AT&T. Though this device support LTE ( band B1, B3, B5, B7, B40), but LTE doesn't work for this device in AT&T network and I guess it is because of support LTE band incompatibility.
I want to enable new LTE band 17 & 12 on this device (so I can use AT&T LTE band).
I am looking for detail steps which can educate me to enable LTE band 12&17 on this device.
I really appreciate your time and suggestions.

Download shortcut master

To my knowledge you can't enable or change LTE bands... Assuming this is like previous Moto devices, that information is locked deep in the device in an encrypted partition and messing with it often gives you IMEI 0 (really bad, no mobile radio at all). We tried this with numerous 3rd and 4th gen devices...
My word of advice is don't try to mod your device in this way, best case it will do nothing and worst case you brick it... Pick up a new or used device if you can't live with HSPA+ (assuming you get that). TBH, depending on where you are, HSPA can be faster than LTE on AT&T's network. lol

Thank you Stokerk - Shortcut Master - does not do much - apart from displaying my current values - again, I am looking to ADD LTE Bands.
acejavelin - Thank you - I may decide to live with this brick / It works on Just 1-band on AT&T - my current Moto G4 Play works on ALL Networks (CDMA + GSM) / Will live with this bad purchase !

How to force VZW E4 (post-unlock) to use GSM/WCDMA/TD

Hello,
I am trying to check how i can have the phone force all bands and not just LTE only. My phone after i unlocked it works great on t-mobile, However, i have to always go back
and change the radio to TDSCDMA/GSM/WCDMA etc so i can get LTE and voice. It defaults to LTE only. Anyone know how to clear this or force on one band ?
Thanks

N900L Network Data Issues LTE GSM WCDMA no automatic switching

READ THE [UPDATE] DOWN BELOW
Many Note3 Korean Variant users also reported this case
https://forum.xda-developers.com/showthread.php?t=2484602&page=115
The problem is that, I can't connect to LTE without losing my Network Radio Service Connection. I can connect to E/G/3G/H/H+ and still have network service, so I can still make calls and text messages, but when I turn on my Mobile Data, when it tries to connect to LTE, suddenly my service gets diconnected and I can't make phone calls nor messages though I could still use the data. I've already tried 3 LTE-Capable SIMS but the issue still happens.
What I had in mind is that it might be because it is Carrier Locked since it is a Korean Variant, but the problem still persists even after flasing other custom roms (this includes Note 7 Port ROMS, LineageOS, Stock-Based ROMS).
I love my Note 3, I will do anything to keep it alive, but still this one problem keeps bugging me...
Why can't I use both LTE data connection and radio service connection simultaneously?
Is anyone out there knowledge and willing enough to help us Note 3 KV users with this issue? :crying:
[UPDATE]
I get it now, when a phone is using LTE it means its not connected to any Mobile Network Service, instead it is connected to Data Network Service, yet it should receive Phone calls and Messages but it means that the phone will disconnect to LTE and switch to GSM/WCDMA (E/G/H/3G/H+) to be able to recieve the incoming call or message. I've tried that with my friends' phones, The first phone is connected to Data and is using LTE and the other phone is trying to call the first phone. The moment I call the first phone, I noticed that the LTE icon dropped to H and then recieve the call, It only happened because the option selected on the "Network Mode" (under Settings/More Networks/Mobile Networks-->Network Mode) is [LTE/WCDMA/GSM auto connect] so that's how it works
But that doesn't happen to my phone, after turning off the Mobile Data (I was connected to LTE btw) my phone doesn't automatically connect to GSM nor WCDMA network, it just stay on LTE mode and I have to manually select the GSM/WCDMA option in order to get Network Service.
So my final question is Why doesn't my Note 3 automatically switches Network Mode?
Note 3
Model Number: N900L
Status: Rooted with Custom Note 7 Port ROM
Condition: Good, No History of Repair
Current Network: SMART Prepaid

Does it work on genuine non custom stock firmware ??

No it doesn't, the problem is already there even before I rooted my device. Flashing stock lollipop rom on odin didn't help either

Please start to read about LTE technology and its frenquency bands.
Then find answers to these questions :
1- My SM-N900L is locked to use which frequency bands ?
2- Wich bands are in use in my actual location (country) ?
3- Is it possible to unlock more frequency bands for my N900L ?
i can provide more help if things remains not clear enough.
Good luck :good:

I tried searching the supported LTE bands of N900L but I can't find any sites that tell exactly what the N900L actually supports though I found out on this forum
https://www.frequencycheck.com/models/AZzWA/samsung-sm-n900s-galaxy-note-3-lte-a
1) A / P / T / V models are made exclusively for the US operator market and for no other people, as their indexes hint (A-AT & T / P-SPRINT / T-MOBILE / V-VERIZON). In Europe, mainly international versions are used - in the case of NOTE 3 - exclusively N9005, in Canada - its own carrier versions.
2) The models N900S / N900K / N900L are identical in the set of supported frequencies. If you rewind the topic on page 9, you will see screenshots of one of these models, which show the frequencies you are using, in one of the screens you will see the treasured frequency of LTE b7. I think that users of this topic can be trusted with respect to information in the topic, but no one has elected you the right to believe solely on the site www.frequencycheck.com.

I did try checking my phone on www.frequencycheck.com, N900L is not on the list..
https://www.frequencycheck.com/models/AZzWA/samsung-sm-n900s-galaxy-note-3-lte-a
N900S though shows that it supports Bands 3, 5, and 17.
I also look it up on wikipedia on where the SMART network (my current network) falls on the list of LTE frequency bands, and it shows that it is on Band 05 alongside with South Korean Networks LGU+ and SKT. The supported LTE bands on my country are Band 1, 3, 5, 7, 28 and 41

I searched for how to unlock all LTE frequency bands on N900L or Korean Variants or Note 3 but the only option that shows up is by accessing the Service Menu on Stock ROM and manually changing the values, which still didn't work for me.

According to my search, N900L is locked to :
LTE protocol : B1 (2100) and B5 (850)
LTE-A protocol : B3 (1800) and B7 (2600)
Now try to find the specific frequency band used by your carrier (he can't use all of the six available bands in Philippines), and activate it.
Wich stock firmware do you use when trying to access Service Mode ? It must be the LGU+ one.
And what code did you dial for the same purpose ?

When you said activate, you mean select the band to be used by the phone right?
- Yes, I used the LGU+ Lollipop Stock ROM
- I typed in the dialpad, *#0011# and changed the network preference to LTE ONLY.

I mean activate only the LTE's frquency band used by your carrier.
Check your PM.

I've already done that, but the problem with radio service network is still present, I can't make or receive any phones calls nor messages.
