Running Task650 AOKP ROM and KT747 Kernel.
I wish to stay on 3G/H+ ONLY and not be on LTE.
However my Network Mode is always stuck in: LTE/ GSM/WCDMA after a reboot.
When I try to change it, it only changes for a split second, and then goes back to LTE/ GSM/WCDMA.
I always have to manually: Click Network Operators, wait until they pop up, Select AT&T, and only then can I select WCDMA preferred, allowing me to stay on 3G/H+ only connection.
After every reboot, I must redo these steps in order to get back into the state I want.
Backup your rom. Restore a stock rom go to more settings / network and check the GSM cdma option. Then restore your rom and you'll be free of LTE. Sometimes I lose my LTE after wiping system and that's how I get it back. I guess the opposite should work for you.

Running same setup, I also do this upon every single reboot to force edge so I get a good signal in my apartment. Pita sometimes waiting while it searches for the network.

After dialing *#*#4636#*#*, I have switched the network type on my phone to WCDMA Only to prevent my phone switching to roaming as I am close to the edge of my network.
It sticks initially, but as soon as I reboot it seem to revert back to the default WCDMA/GSM. I'm using an ASOP 4.0.3 build, so I'm wondering if anyone with a stock build can give it a try and see if this setting sticks between reboots on their device.
Thanks!
It is my first forum post and I believe I am posting it in the right section... I tried finding a similar problem to mine, but seemed to only find people that wanted to turn LTE off instead of on. The AT&T Galaxy S3 phone is rooted and I have gone between ics and jb roms and have gotten LTE to work every time. The problem is after I reboot the phone I lose LTE. I get 20+ up 10 down on LTE. After I loose LTE I get around 8 up 4 down.
I have tried.
1.) Re-installing a rom which gives me LTE until I reboot phone.
2.) I have tried installing modems from http://forum.xda-developers.com/showthread.php?t=1831898. If I have lost LTE after reboot, I can (9 out of 10) get LTE to work again after installing a modem. I lose it once I reboot the phone again though and am unable to flash a new modem to get LTE back to working and it won't unless I do 1.) again.
3.) I have made sure apn settings are on the correct pta lte setting. Usually most of the rom's have that already set to begin with.
4.) I have tried the *#2263# to change it to LTE. This WORKS and will reboot my phone into LTE everytime, but I lose being able to make phone calls, etc. From what I understand as well, I am unable to go to 3g/2g after settings LTE ALL and I don't want that either...
It is the only problem I have had with this phone. I notice a lot of times after I install a rom and reboot, it upgrades, and I lose LTE. I install a modem and get LTE back. I reboot phone normally without doing anything to the phone and it upgrades apps again and I lose LTE. That is the only conclusion I can come to as to why I lose LTE after reboot.

I am in the same boat as you. I can force LTE with *#*#4636#*#* and setting it to LTe only. But I lose phone calls and if I restart it goes back to WCDMA.
What rom are you using some roms don't have the late icon they have 4g instead. Also double check that you have the right lte apn enabled

Yea I realized that jb roms do not show 4g lte, they just show 4g. I check to see if I have LTE by doing going to the Settings->About Device-> Status and looking at Mobile network type... and/or a speed test as well.
I came from and tried these rom's

WanamLite Smooth,Stable & Battery
Right now I am on Stock TouchWiz Jelly Bean PORT (JellyBean 747 Milestone 3)
I have gotten LTE speeds on every single one of the roms until I reboot phone.
[Update- Best Solution So far]
I found that using the WanamLite Rom http://forum.xda-developers.com/showthread.php?t=1782732 enabled me to get LTE back fairly easy.
Everything is in the Settings->More Settings->Mobile Networks area.
1. I entered in a new Access point and just put Name: "pta" APN: "pta". You can fill out the rest like the MMSC, MMS proxy, etc but I did not need to.
2. Then went to Network Operators and waited for it to search for the networks (takes a minute or two). It showed up for me as two options being Maritime and AT&T. I selected Maritime and registered it. I was not able to register on AT&T and I don't even know what Maritime is. However,
3. I went to Network mode: Set it to GSM/HSPA/LTE(Auto mode). I get LTE every time.
Every time I reboot I can get LTE to work by doing steps 2.) and 3.) and is a little annoying, but better than having to flash a rom every time I reboot and lose LTE. I would like to try and find a solution though where I wouldn't have to do this every time I reboot.
[EDIT] There might be roaming charges, but by disabling Data roaming you should be fine. I believe you might incur charges if you try connecting to this network while on a cruise and have data roaming enabled. I have not done a lot of research on this so I could be wrong.
I was wondering if there is a way to make my tMob SGS3 do better at seeking and maintaining a WCDMA connection?
I know I can change the Mobile Network Mode to WCDMA only, and I do sometimes.
However, when it is in Auto mode, it switches back and forth constantly between GSM and WCDMA. In my home when I force WCDMA mode it has 2-3 bars of WCDMA and it does not drop the connection. When I put it on auto, it switches back and forth every minute or 2. I flashed and tried every modem possible but the results are the same.
Is there any way, besides WCDMA only mode, that I can make my phone more aggressively seek and keep WCDMA when it is available?
Thanks!

Dude I feel ya. I seriously think it all started once they switched to the 1900 band for 3g. Cause when I had my HTC HD2 it was mostly 3g in my house. Now it hardly ever switches to 3g unless I force it.

It works great when I switch it to WCDMA only, however I keep forgetting to switch it to GSM/WCDMA when I leave the house or work. I'm thinking of getting some TecTile NFC stickers to cause my phone to remind me to switch or maybe try to find a way to automate it with them or something.
If it sits at G or E until you start a data transfer and then jumps to 4G this is how it was originally set up to operate. The intent was to save both battery and banwidth. It was like this for me until I updated and it stopped. It was annoying so I'm glad it was changed. But if you are on either build UVALEM or UVALG1 try updating to the latest official build UVALH2.
Otherwise it may just be the tower you're connected to is under heavy load and is trying to conserve bandwidth, or it may just not be functioning correctly.
One other thing it could also be is if your area hasn't been refarmed yet. (It may be that this is what changed it for me but its been a while and I know I had updated about the same time I noticed it, so I attributed to that) the more I think about it now, if updating doesn't change its behavior, this is probably what's going on.

Thanks. I am on UVALH2. I think the way it is supposed to be setup is to sit on UMTS while conserving bat/data and switch to HSPAP when moving data (Both WCDMA protocols). It actually has been much better today. Don;t know if the tower in my area was having issues the last few days.
I checked for NFC programs that would allow me to change my networks based on location and none have that fine level of settings.
It isn't really a problem if I switch it to WCDMA only, it's just that I forget to switch it back to both when I'm on the road and I end up missing calls.
Well, I guess that answers whether it was the update that did it for me! I'm guessing it must be due to the network refarming then. Like I said, it did the same for me for a while, but I haven't had it hapoen at all for some time now.
You could look for an app that lets you create location based profiles. You can set it to be one way at home and when you leave it'll automatically change to your other settings.
I would imagine Tasker could handle this as well, but I've never used it.

So I'm on a CyanogenMod 10 nightly, and I am having the problem of the Preferred Network Mode setting not sticking, like several other users apparently, and after searching the forum I have concluded that there is no actual solution yet. Right now I can get to 4G LTE by manually setting to LTE/GSM/WCDMA in the Preferred settings, but it always reverts back after reboot. Apparently this does not happen to everybody; how should I fix this?
I posted in the CM Nightlies thread but no one seemed to notice. I hope this can get to the devs so they can fix this eventually I guess.
The following may be of use
http://code.google.com/p/cm9-msm8960/issues/detail?id=39
According to that, this is a hard-coded problem caused by the settings in the two places not matching?
Try going to your dialer and typing *#*#4636#*#*
Use that dialog to set it to what you want and hopefully it will stick then?
I never encountered this problem myself because I never want my phone on LTE as the battery life is pitiful as is and LTE only makes it worse.
Mine is set to WCDMA only on quattrimus cm10 and it sticks no problem.

Had the same problem, except that it dropped data service every 10 mins or so. Didn't even had to reboot. I could fix that by changing the network settings from lte/wcdma to gsm/wcdma. Another thing I witnessed when on lte that it would recover data connection when the process was restarted e.g. when activating and deactivating airplane mode.
Unlike most people, I'm actually wanting to keep it on LTE only, since I just keep data off until I need it, and when I need it I want full speed.
The phone always reverts back to GSM/WCDMA, turning off LTE.
I messed around in *#*#4636#*#* but it didn't really do anything.
I've been having the same problem on my Razer Phone 2. I don't think this is specific to the phone itself, but. I'm getting desperate for a solution. I change the preferred network type in the *#*#4636#*#* menu, I get LTE fine..... As long as I don't restart the phone or go on/off with airplane mode. Then I have to do it all over again. Does anyone know how to make this stick?
Good morning all.
My S9 is completely stock (Android 10) and I don't want to install any custom ROM.
Is there a way to force LTE only (Three network/UK)?
I have tried #*#*4636*#*# but this doesn't work. I have used a couple of apps that have given me access to the settings and changed it to LTE only and this is confirmed in the mobile settings page but the phone keeps reverting back to 4g (not 4g+).
I definitely have 4g+ here because it does connect if I reboot my phone and the download speed is double my normal rate but I cannot get it to stick.
Is there a specific APN I could use?
May I ask you for advice?
Thank you.

You can try with Force LTE Only app on Play Store since Scamsung is kinda blocked the Radio edit part on ONEUI. But be aware that on some firm, Scamsung devices will not be able to make phone call or receive text msg when on force LTE only mode!
That's one of the apps I have used but the phone just reverts back to 4g (even though Network Mode now shows LTE only).
Looks like I have been misunderstanding my network terminologies.
What I am trying to do is force my phone to stay on the 4g+ signal, because I get much better downloads. It is definitely available here because I connect to it for a few minutes if I reboot my phone. My phone is completely static with good, no fluctuations, signal.
Can this be done?
