Locking to LTE only - G3 Q&A, Help & Troubleshooting

Can you guys lock to LTE only? I cant seem to lock it using the dialer code while on the same network i can with my note 3.

I'd also love to be able to do this on my VS985. The secret menus don't work on this device though. It used to be possible on the G2. I'd lock to LTE Only where I got *just* enough LTE service to get great speed but the phone kept wanting to downgrade to 3G.

Please help LTE stopped working not sure why!!!!

Bought my phone form Rogers. LTE was working fine.
Was going to USA and paid an online company to send me unlock code.
Used it and went using Tmobile which only has EDGE data.
Just got back swapped back in my SIM From fRogers and can only get EDGE speeds.
Tried reboots rmoving SIM card.
Also made sure settigns were correct for Rogers APNs and also that toggle was on for GPS/HSPA/LTE.
To no avail.
Briefly, I toggled on and off the apn setting from ROgers LTE to tethering LTE and low and behold it seemed to work.
But now it is back to stuck on EDGE and nothibg I am doing can help.
Can this be a byproduct of the unlock?
Is my LTE faulty?
I s there some hidden menu where perhaps a setting can be changed for a fix?
I am depserate as the alternative is to return the phone and they are on backorder everywhere now.
There is no lte on tmobile yet. Second the tmobile note 2 has dormant radios that will only activate the lte capability by software update.
Im going to research your problem a little more ill send you a pm as to why it isnt going back to lte functionality if I find out something first...

I have a Canadian note 2 that had working LTE.I had it unlocked via a code emailed to me then next used it on tmobile at edge speeds.
Since returning home i cant get back onto data speeds above edge despite reboots.Simcard/battery pulls.
I ensured my network and apn were correct and that in setting under mobile the toggelchoice for auto including gsm//hspa/LTE was selected.
Are there perhaps some deeper settings via dialer code than might be able to turn back on the hspa/lte radios?

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.

[Q] LTE only

I am using ParanoidAndroid 4.3 on my Galaxy Note 2, I've notice with 4.2.2 and 4.3 that I can not access *#197328640#.
I need to access this in order to get LTE only, unless someone else knows otherwise. Please help. I didn't want to go back down to 4.1.2 Cleanrom.
Hopefully someone has a workaround, or if this issue has already been addressed, can you post link.
Thk you

Im not 100% but i seen this asked a few times. I dont think about of the dial codes work for Aosp. And you can only pick up LTE in areas where your carrier has It. I know here in Jacksonville Fl its very spotty
I use lte only in Chicago. Works gr8 on Cleanrom 5.0 for skype while driving. Cant hve it switching to regular 4g. Might have to stick with that. Thk u

No problem bro. I never heard anyone trying only use LTE. I have heard alot of people trying to turn Lte off to save battery..lol... if you could lock it on LTE only than whenever you are away from an LTE area than you will have No data till you pick up LTE again.
Dont forget to hit thanks if Someone helps you​
Unless AT&T has implemented Voice over LTE (VoLTE), setting your phone to LTE only would leave you unable to use your Note II as a phone. Maybe you were looking at disabling GSM and EDGE instead, leaving you with WCDMA and LTE?
I only use my phone for Skype and google voice sms and calls & internet. I don't have phone service. I have an IPad 4g lte sim in my phone. I am able to do Lte only on 4.1.2. Not anything higher.
Would really like to use aosp or aokp ROM. But without that Lte only driving and talking going to H+ or H is Hell over Voice. Chicago has gr8 lte coverage.
Will probably have to stay with touchwiz.

Weird problem with PUK

Hey XDA
So I PUK locked my internal LTE SIM. Go ahead and laugh at me...
I can still use my phone fine on CyanogenMod, or any AOSP based ROM, just without LTE. Not a real big loss considering Sprint's crappy LTE coverage. My issue is that I want to try out the 4.3 TouchWiz just to see how it is, but TouchWiz won't let me use the phone at all. Prompts for PUK and new PIN. After some digging I realised that CyanogenMod doesn't use the RUIM/SIM CDMA subscription method by default, it uses NV. I confirmed this by changing the subscription mode on CM to RUIM/SIM, and sure enough, "Enter PUK and new PIN". reflashing cm got rid of that. Okay, so basically what I'm getting at is, is there a way to make TouchWiz use the NV subscription method, so that I can still use it, albeit without 4G LTE?
Thanks

Explain my 4g LTE woes, Verizon on T-Mobile

I may be trading my Verizon G4 for a T-Mobile H811 but before I go through the trouble I'd like to see if my problem can be fixed.
My network options are:
Global no sub-network menu
LTE/CDMA also no sub menu
LTE/GSM/UMTS with sub menu options LTE/Legacy 3GPP multi, GSM/GPRS/EDGE only, and UMTS/HSPA/HSPA+ only and the option to choose network operators.
When I choose LTE/CDMA I get 4g LTE all the time, great speeds, but am unable to send texts, not sure about calls(don't use the phone much for calls)
If I choose Global I get intermittent LTE but mostly HSPA or HSPA+. Again texts only work when it switches to H.
If I choose LTE/GSM/UMTS I mostly get HSPA but occasionally it will switch to LTE.
I'm not used to having all these network options to choose from. I've tried a few different APN settings and all give the same results. I'm in a very good LTE coverage area and my G2 always ran on Band 4 LTE which is enabled on my G4 and obviously works in the correct mode based on my speeds 28mbps down, 18mbps up. Plus Verizon LG G2's are able to work correctly on T-Mobile's network and they have the same bands as the G4.
If my phone has the band's enabled to work with T-Mobile, namely band 2 and band 4 LTE, then why can't I always have LTE AND be able to text and call at the same time?
If anybody has an answer to this I'd love to hear it! Otherwise I'm going through with the trade (and trouble of setting my phone back up all over again).

Have you tried to delete the Verizon Apns? I used a Verizon g3 on ATT and had some issues until I cleared all APNs and set new ones up.

I'm having the same issue, i just got mine yesterday. I tried rooting and trying to disable and enable lte bands from the hidden menu but it didn't do anything. I also tried the epc apn and for some reason still kept giving me lte like the settings aren't saving.

My tip to you is don't disable any of the bands. You can enable all you want. I made the mistake of disabling thinking it would force the phone on certain bands. Then went out of town and lost all data. Somehow I remembered the command prompt line to get back into the hidden menu, re-enabled and I at least got edge...
