Not sure. All i know is when I put my t-mobile sim in mine I only get edge no 3G as I do know the bands for HSPA are not there but not sure about LTE
I had my att g pro on tmobile and got lte, when i get home i will put the tmobile sim card in and get the apn i use. That's all i did last time (insert sim and put apn manually)

I only got edge at first too but I know I live in a refarmed 1900 MHz area so I went under settings to network operators and searched networks manually and chose tmobile rat:14 when it gave me my options. Now I get 4g umts- hspap. I use wifi while home and after I leave sometimes it will revert back to edge. I went into the hidden menu but I didn't see how to select band prefence anywhere so im lost on how to get lte to work.
I know at&t and tmobile use the same lte band I just cant figure out how to select it to make it work. Try selecting setting>networks>tethering and networks>mobile networks>network operators>search networks. A few different tmobile ones should pop up with rat:2 rat:3 and rat:14 underneath. When I selected rat:2 it only stayed on edge but all other options gave me 4g.Hope that helps to at least get you 4g working.

Ok that would be great if you can post the complete apn your using. I have the fast.t-mobile but maybe another part of mine is incorrect...
I am pretty sure for LTE to work on T mobile, you have to make sure the apn is set to fast.tmobile.com. Your Sim might be setting it to the default epc.tmobile.com, which will only give you HSPA+.

I appreciate the help but for some reason it still wont get lte. I have tried all the different apns I can find and after I enter it if it still only goes to 4g then I reboot. Is there anyway to select lte only from any hidden menus or an app or something?

on other phones, the following menu lets you pick what you want your data to be: *#*#4636#*#*, then pick lte/gsm auto from there.

I tried but it doesn't have the option to change the network mode. I actually just edited my build.prop to enable network mode under settings and it worked!!! I finally got lte by choosing lte/wcdma option. When all the options appeared my lte appeared to be shut off .So all I had to do was turn it back on. Huge thanks to MrDSL for the help.
After changing my network mode to lte wcdma my phone kept saying roaming notification off at the top of the status bar and all I could use was data ( lte at least) and wouldn't make calls and the network mode menu actually disappeared. So after putting in a at&t sim card and rebooting my phone about 20 times the network mode menu popped back up and allowed me to change my preference to gsm/wcdma/lte and luckly its working perfect now.
I have a g pro on tmobile but for some reason theres a few places where I don't get 4g or lte and the phone loosses signal for a min or two then I get E is this happening to someone else ?

I have an unlocked stock rooted AT&T i747 running 4.1.2. I want to use it on the Bell network. When I put in a Bell sim, it shows it has service, and the pda.bell.ca APN shows up, but it can't find the Bell network, only Rogers. Just wondering if anyone else has tried the same thing and had success or no? As it is I cannot call, text, or browse... Please let me know if there is anything I can do.
Is there an option in the network settings to select lte or wcdma?
Did you check to make sure the phone isn't listed as being blacklisted?

I haven't located any settings about WCDMA or LTE. On my i747m I'm used to being able to toggle between 2G/3G/4G. Nothing like that here. Bell's IMEI check approved it, and it's not on the national blacklist.

http://forum.xda-developers.com/showthread.php?t=1434995 has the APN, I assume you already looked it up but can be useful.
Getting service but no data is usually just not having data turned on.. So obvious question: Do you have it turned on in your settings/pulldown menu?
If your APN checks and data is turned on, you might have to give Bell a call (don't have to tell them you have a US variant).
Thanks for your input. Data is definitely turned on. However, please remember that it's not only data that isn't working. I am also unable to call and text.

Can you check to make sure your baseband matches your bootloaders? If it does, I'm out of options for now. Bell (or someone else) can probably help you further.
Sorry for not being overly knowledgeable...
How can I tell what bootloader I'm running?

It seems it should be that way... the phone is unlocked, but when I put a Bell sim in it it says emergency calls only. The only network that comes up to set as default is Rogers. Can you advise me as to how to make 100% sure the phone is unlocked?

Which carrier are you trying to use the phone with? If it is Telus/Bell/Koodo/Virgin, it should work without changing anything.
The only networks that support GSM are Fido and Rogers.

The ATT should work on Bell and Telus. My Bell i747m could roam on ATT when I travelled to the USA.
Just to confirm: you can connect to the Rogers network but not Bell or Telus?

I'm having the same problem with Three UK, no 4G. Although 4G worked on my Lumia 1020 with the same SIM a few days ago.
If I go into the hidden menu under LTE you can set it to use LTE and it connects to 4G brefiely then goes back to 3G and it never shows GSM/ WCDMA / LTE auto in the mobile networks menu, just GSm / WCDMA auto.
I noticed on the demo unit in a Three store that the phones software version was V10a-EUR-XX whereas mine is V10g-HKG-XX.

Is there anything that can be done without root? I've tried setting the LTE in the hidden services menu and it connects foe a few seconds and then goes back to HSDPA. If seeting to LTE only it stays on LTE but not sure how it will work if I leave 4G coverage? I've also enabled fast dormancy but that doesn't seem to help.
There was a discussion about this in the UK thread, some phones came with 4G deactivated (on the 800MHz band used by 3 and Vodafone) that had to be activated at every boot. Replacing it fixed the problem as its not supposed to happen. But since the phone is from Asia who knows. Im not sure if flashing the eur version of the rom would work?

fast dormancy is a network dependant setting that has nothing to do with the generation of signal you are receiving.
The only other option you have is to try and flash another firmware version.

LTE will work from the hidden menu, or download 4G switcher from the Play store which will take you to the menu also. Just change it to LTE/GSM/WCDMA and it will work on the 4G network (at least on 3 UK). LG UK support will not help as it came from HK. I still want to know if I can flash a Euro 32GB ROM to my phone to get it working natively.
make sure u have activate your LTE with your carrier,i you have done it,and still didnt have LTE, try the hidden menu,or try 4G switch frm playstore,rooting and deleting lteconfig from system/app would be your last option (i prefer this)

my lte/3g/2g settings was everytime reset to 2g/3g modus when i got back to settings. i deleted lte config.apk and the .odex file, rebooted and BAM! it keeps on lte/3g/2g

I had the same issue (no LTE option in Networks configuration menu), until today: My phone installed firmware V10i-HKG-XX, and now I have the "GSM/WCDMA/LTE auto" option in Preferred Network Mode.

Do the following -

I'm currently using the AT&T H810 on Cricket Wireless and am wondering how to get the data to work with this Verizon variant. I can make calls when I put my Cricket SIM card in, but I get no data. Any ideas or anyone already get this working? Thanks!
Did you change the APN settings? Also, AT&T uses LTE bands: 2, 4, 5, and 17 primarily. The Verizon G4 doesn't have band 17. so you are not going to get very good coverage in buildings or at far distances from the tower.

I know I had to put the APN settings in myself when using a T-Mobile SIM. I would Google "Cricket APN Settings" and then go to the settings on your phone (under more I believe), and edit the APN. You can't unlock band 17 unfortunately.

Yeah, why can't we unlock band 17? I tried using a few methods listed where you write to the NV ITEMS and enable all kinds of bands, but it still didn't work. I only got LTE when I force it via a hidden menu setting, but then I couldn't make or receive any calls. I get HSPA and HSPA+ but that's it and there's a constant icon in the notification bar of a white sim card with a question mark on it...!?

Because the phone doesn't support it. You can't unlock bands that the phone doesn't have to begin with.

Hi, I have a LG G4 H818N LTE model with dual sim running firmware v10c.
According to the mobile carrier, they support 900MHz and 2100MHz, yet I am unable to obtain 4G connection on my phone. I have enabled the option in the sim settings for "4G/3G/2G" on the SIM that I want to use for data and set that sim as the sim to use for data connection but it still only connects at H+.
Perhaps the carrier is using Cat 6 LTE. Is there a way to enable Cat 6 LTE on the H818N?
Is there a way that I can test LTE connectivity on the phone or are there perhaps any settings that I may have missed to force LTE connection?
I previously had an LG G3 D855 which connected to 4G without any issues.
Is there a file where I can manually edit the 4G bands for my phone?
Finally, slightly off topic. Can anyone explain to me what a KDZ file is?
Assistance would be highly appreciated. Thanks.
mine has a working LTE on both sim 1 and sim 2 but not simultaneously. i found out that the apn is alittle bit buggy. check your apn and set the primary.
Thanks, would you mind walking me through the steps that you followed please?

I'm having a similar issue with my 818N. I can't get 4G/LTE.
Has anyone worked out why or how to fix it?
The hidden menus don't allow me to select lte bands they all just say fail after I select them.
In the RAT menu I am unable to select LTE only, it also fails.
It's as if LTE is disabled?
I tried installing 818P software into the phone which worked fine however I still couldn't connect to 4G.
I give up
It turns out that my phone was faulty and I've returned it to HK for a full refund. DWI were good to deal with and were fast to refund me my money once they confirmed that it was DOA.
