I have read that you can change your APN settings to turn off LTE. However, I found another way (with the help of carefreelife). Use at your own risk! I am not responsible for any harm you may do though it seems fairly safe to me!:
UPDATE: THERE IS NOW AN EASIER METHOD TO DO THIS WITHOUT PULLING THE SIM AND REBOOTING (check out post #47 below or use this link)
http://forum.xda-developers.com/showpost.php?p=37310325&postcount=47
[OLD METHOD]1) With phone on, take off back cover and press your SIM card so it releases from the spring. It won't come all the way out as it's blocked by the battery. This seems fine - I didn't bother trying to force it out as I didn't want to break anything...
2) Once you see the message that the SIM card is removed, go to the dialer and dial *#2263#
3) You should see a menu with band selections. The current setting is "Automatic". If you switch to "GSM All", you will be EDGE (2G). If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G).
4) Press the SIM card back into place until it clicks. For whatever reason the phone will not recognize it until you reboot. Upon reboot you should see your new setting in effect.[/OLD METHOD]
I was attempting to follow this procedure for the S2:
{Trick} Get Around "RAT SELECTION RESTRICTED" on i897 modems! - xda-developers
...but I couldn't get the SIM out easily so I left it in...and followed the steps. It wouldn't recognize that the SIM had been reinserted so I gave up and rebooted...and it worked! No need to mess with airplane mode or anything just follow the steps above.
I was then able to follow the same procedure and turn back on the default setting which was "1) Automatic". After a reboot I am again connected to LTE.
Reason I'm using this: I'm testing a major battery drain issue that might be related to LTE/HSPA+ switching.
Reason you might want this: If you have poor LTE signal or even poor HSPA+ signal and want your phone to stop trying to connect to that network, this will stop it.
UPDATE:
A little bit of bad news here:
I have been on "WCDMA All" (HSPA+ aka 3G4/G, with LTE disabled) for 10 days now with ZERO problems whatsoever.
However, I am pretty sure that whichever you choose, if not "Automatic", you will be locked to ONLY that band:
i.e. if you choose "WCDMA All" you will not only be disabling LTE, but also 2G (EDGE) as well. You may not need it (and if so, it will not effect you) - but if your phone loses the HSPA+ signal, it will not fall back to 2G unless you change the setting.
I tested this theory by setting my phone to "LTE all" and trying to call myself from another phone. The call went straight to my voicemail. LTE is data only (for now) and when you receive a call, it switches to HSPA+. Unfortunately, since I had set my phone to "LTE All", it stayed on LTE and could not receive the call.
This may not be a deal-breaker but it's something to be aware of, for sure. I only tested "LTE All" because it was easy to do so, but I am assuming the same applies for the other settings...only "Automatic" would seem to pick the best available network.

Edited OP and changed thread title. Please help me test this. Thanks!
Just out of my curiosity, can you not do this:
settings > wireless and networks > more settings > mobile networks > network mode > GSM/HSPA
I have the Bell version, which is similar to ATT's, wondering if ATT disabled that option.

Yes, it is disabled on AT&T versions. If you try the method I listed above without removing the SIM card, it will be blocked as well.
AT&T does not want us to have any control over which network we connect to. It's been speculated that they want us forced on to LTE to take strain off the HSPA network. Honestly I think that's fine - though I prefer to have a choice - except that I suspect LTE switching is causing my battery drain issue and I need to turn it off in order to test that theory.

carefreelife at Android Central forums showed me that WCDMA All is the proper setting to disable LTE and stay on HSPA. It's working for me and seems to be perfect!

My battery life is great too - there just seems to be a bug that causes it to suddenly become terrible and drain fast until it's rebooted. This is just a method I'm using to test it.
It's possible that disabling LTE can increase battery life but I'm not sure there's any evidence that LTE uses more battery than HSPA+. On older phones the LTE was not integrated into the SoC and thus was a power hog...but it's integrated on the S3.
For users who are on fringe areas and receive poor LTE or HSPA+ coverage...the phone will use extra battery trying to connect and stay connected to those...even if it's [mostly] unsuccessful. Using this method would be a good idea for people who would rather just stay on the bands with strong signal and stop wasting battery trying to get on LTE or HSPA+ fruitlessly.
Thanks a lot for this I've been wanting to switch to 2g only THANKS

Hey what's up. I don't know what combination bands are - haven't ever used the Captivate.
And yes I'm still working on those battery issues...I'm hoping that THIS fixes it...even though it would meaning losing LTE for the time being...at least I'd know what's causing it!

You can mix the different bands between wcdma and gsm and their frequencies,that way you can get the best signal in your area.
How's that LTE test coming?

I can't guarantee this works with any modifications to stock as I have only done it on my unrooted stock AT&T S3.
CM10. I just learned that you can only use dialer codes on stock roms. AOSP roms don't recognize them. There's a small few that work. obviously this one doesn't. Where can I find the APN info?
Nice find!! Works perfectly with my AT&T Galaxy S3. Going to test it out for a few days. I have 4G LTE where I live but when I go to college in the fall there won't be any LTE. This will come in handy!
However, with the WCDMA option enabled, does this mean you only have access to 3G and not 2G? Sometimes when I am in rural areas there is no 3G so I need to use EDGE or GSM. Hopefully with the WCDMA all enabled 2G is still accessible.

That's a great question. I have looked at it like a hierarchy but there's plenty of reason to believe it could be otherwise. There's not really anywhere in Miami I can go that doesn't have really strong HSPA+ so I don't know how I can test it. If anyone can do this test themselves and see what happens when you leave a 3G area please post results here.
Actually, once I am done testing the battery drain I could switch from Automatic to LTE and find somewhere in Miami where there's only 3G and see if it switches down to 3G or just loses signal entirely. Someone could also switch to LTE mode and try to receive a phone call...if it is truly locked on ONLY LTE then it won't be able to take a call...
The more I think about it the more it seems like this could be a major drawback of this method. I look forward to testing this later and hearing what you guys find as well. Thanks!

I'd also love to know if 2G works, but I can't while in North California. There isn't a single place within a 20 mile radius of where I live that doesn't have full LTE and HSPA+ coverage since so many people live here. I go to college in a fairly rural area in California though so in late September I'll be able to confirm if we can get 2G with the WCDMA method.
Hi all,
I was in Vegas a few weeks ago and LTE was killing my battery. I found the code to get to the menu that allowed me to switch it off. Embarrassingly, (or possibly not I mean I was in Vegas and may have been loaded at the time) I have since forgotten the code and can't for the life of me google it up again. If anyone knows what it is, I would love to get it from you. It looks like ATT just got LTE running in Denver and I would like to at least run a speed test. Anyway, thanks for helping.
this is not possible in the stock att rom.. they disabled those menu entries.. you can change your apn to phone apn.. to get only 3g/4g

Didn't you forget a #* at the end to make it *#*#4636#*#*
Figured it out
OK, I googled it out. The method that I used was *#2263# But this must be done with the SIM card released. That will take you to the RAT selection menu without any restrictions. There is a selection for automatic choice which will pick up LTE if available or WCDMA (all) for HSPA+, 2G/3G etc without LTE. Turned LTE on and the speeds were beyond ridiculous (47886kbps vs 6646kbps) but I could have lit a cigarette on the phone while watching the battery drain. Going to stick with HSPA+ unless I need to dl large files for some reason.
Something is wrong with your phone, I'm always on LTE and I get at least 14 hours out if it with HEAVY use throughout the day.

Follow up.
So after I figured out the LTE switch, I went ahead and threw CM10 on my phone. So far the battery issues are not nearly as bad. I assume that something was conflicting or causing an issue. Who knows? The performance is better and that is what counts. Thanks for the replies.
Change APN
The easiest way I have done it is by changing the APN.
Hey XDA,
I've been following this tutorial for how to add some bands but my phone simply doesn't see any networks when scanning for LTE on band 38.

I could not find the LTE on my phone with this SIM but when I inserted it in a OnePlus One I could browse in 4G. The SIM isn't the issue.
Nobody from all this smart guys that are here could not tell us how to make LG G3 to open band 38 on the LTE so we can get 4G internet on Digi Mobil ???? Right now since the android 6.0 update cant even access the hidden menu using that code.
Also another matter , since the root of Android 6.0 the micro SD card can not be recognized anymore.....don't matter what rooting you try the micro SD wont work no more. Nobody bother to fix this yet. Every one acts smart and writes here but all he does beat around the bush.
Awaiting for real answers.

Hi, I know that it has passed a long time since you've posted but here goes :
After trying to add band 38 to LG G3, i tried to update to Android 6.0, but couldn't because my phone was rooted. So i've flashed my phone to Stock ROM. If i remember correctly, my phone came with 5.0.1. Stock ROM is 4.4.2. After many, many updates i installed Marshmallow. Try to make all possible updates using the phone's software center, after that check with LGPCSuite if there are any other updates (they call it upgrades) and do them. Just like you i can't access the hidden menu anymore, and my micro SD card is recognized. Apparently after upgrading to Android 6.0 fixed it. (It shows 4G instead of H+ or 3G, now i only need to test the speed)
Hello.
AT&T has disabled all the international GSM\LTE bands on Z999, making it unusable outside of USA (at least in countries with GSM 900\1800, UMTS 2100 & LTE B3 & B20, like the one I live in). In order to change that, we need to turn on the Qualcomm USB Diag port, and for this, the phone has to be rooted.
I've been trying to root my AT&T Z999 for some time now, without any success, unfortunately. However, searching forums after forums, sites after sites, I've discovered the surprisingly easy method of turning on the Diag port without root.
It appears, that Axon M shares a lot with Axon 7, at least the secret key combination to enter Factory Test Mode:
Turn off the phone
Press and hold Power + Vol DOWN buttons until you see the screen "FTM" (see attached screenshot)
You have to press both buttons for the long time, do not release them when the phone starts - just wait until you see the screen. And that's it - you are now in Factory Test Mode and PC sees your phone as "ZTE Handset Diagnostic Interface (COMxx)"
Now, in order to change the bands, you have to follow these guides one after one:
Backup IMEI and NVRAM (ignore all the steps to turn Diag port on, you've done that already)
Unlock LTE bands
Mod edit: Link removed! (this guide in in Russian, but all screenshots are in English & every step is pretty clear)
You would need this tool also.
Please remember, these things are complex, and require considerable experience with Android & Windows. DO NOT START unless you feel confident that you know, what you're doing. I'm serious. Do not try this, if you're not experienced.
WBR,
Draco.
Why mods deleted the link? Google translate exists.
Edit:
I've managed to get the data from the phone using QXDM.
lte_bc_config contained the value of "2251800618993690" now I'm parsing the info how to edit this. Seems like the tutorials don't really match this device. Now I wonder if the chipset can handle invalid data and just input all 1's. Unsupported frequencies just won't work.
Edit2: Writing all 1's didn't work.
Edit3: I wrote this value: "2251802901219551" Calculated with CDMATool. But it seems like the AT&T firmware only finds edge network. I've double checked the bands to be correct ones. So now I will switch to the chinese firmware.
Edit4: Final edit. Turns out you cannot flash chinese firmware on AT&T device. Sigh so my unit is stuck to EDGE/wifi only.

Every Quallcomm device has almost the same NVram configuration rules, the difference is usually on how to enable diagnostic port, but for Z999 I have figured that out already. So, for the configuration process, every Quallcomm guide should work.
I've successfully enabled Z999 to work with 2G & Edge in my country using these guides. 3G & LTE don't work yet, but I'm sure they will eventually. I don't believe Z999 lacks the hardware ability to use LTE B3 & B20 (and other bands), it has to be something wrong with NVram parameters.
For me 2G and Edge worked out of the box in Finland. Tried to enable more but only thing that changed was power usage. Not worth it

It means success unlock 2G/EDGE, not yet with 3G and LTE? When buy the device, it can use other carrer to call and 2G.
When you finger out the way to unlock LTE, please share me.
by the way, do you have the way to enter fastboot mode? I tried the "volunm + &power button" but it just do a normal restart into android.
Fair warning to everyone trying this, make sure you actually do a backup of your IMEI. I didn't and after screwing something up my SIM is no longer detected, and my IMEI is no longer available.

Hello! So I got the Pixel 6 Pro and I am coming from Galaxy S20U (Owned Pixel 1/2/3/5)
So on my S20 I can change NR/LTE bands as much as I like without root by using an app or the hidden menu *#2236#
Where I work all day its all concrete walls, so me locking LTE Bands its a must.
I can not do that on my google Pixel 6 PRO and yes I tried *#4636# but those options do not work with me because you can not lock bands.
I am ok If I need to root my 6Pro in order to do this, Will Network Guru do this once rooted? I am willing to include reward $ for whoever helps me with this.
Thank You
I'm sad to say that Network Guru simply won't work because Pixel 6, Pixel 6 Pro uses Shannon Modem for 5G, which is an Exynos modem (if i'm not wrong) and Network Signal Guru requires Qualcomm Modem to work.
**edit: typo**
Under settings__internet__gear wheel next to your carrier and scroll done to preferred network type. Unless you don't have that option.
I'm still trying to figure out diag modes for this phone. I can get the modem and serial devices to show up. Per my conversations with cstark:
resetprop ro.bootmode usbradio
resetprop ro.build.type userdebug
setprop sys.usb.config acm,dm,adb
setprop persist.vendor.usb.usbradio.config dm
Revert:
setprop vendor.modem.logging.shannon_logging false
setprop persist.vendor.modem.logging.shannon_app false

Everything seems to be controlled by /vendor/bin/modem_logging_control and /vendor/bin/dmd.
Regular START/STOP calls to modem_logging_config from root shell can yield usable logs. We can also get the apps started in special SHANNON_DM or SHANNON_APP modes, but no idea what to do with them.
For example:
modem_logging_control START
modem_logging_control SHANNON_APP
modem_logging_control STOP

Click to collapse
Logs saved to /data/vendor/slog/.
The Shannon DM version floating around is too old and I haven't gotten a decent scat setup. Airscreen might work but Network Signal Guru doesn't. No tools for this phone are good at the moment.
And that's the extent of our knowledge at the moment...

Thank you, I will try to be checking on this if decide not to return the phone. Is Airscreen a Magisk Module?
No, it's a desktop app. There is no band locking.
Can someone tell me the benefits of this mod? Genuinely interested.
Lower frequencies penetrate walls and concrete better than higher frequencies in the spectrum, at the cost of speed.
Locking a 5G/LTE band helps save battery life because it prevents constant hunting for a better signal between bands.
You can try your luck with 'Shortcut Master' app on Google Play. Once opened click on show all apps -> Phone services -> scroll until the bottom and click on band or radioinfo and click on Launch. Then you can change the band and frequency as per your liking.
No wifi at work?
A lot of workplaces have strict firewalls and network policies in place so it's understandable to use your own network connection for non-corporate usage

With this method let's say I choose class 9, it will remain locked?
I believe this is a WCDMA band selection and will have no effect on LTE/5G, am I wrong?

Not sure but I'm really frustrated that I don't get the option to at le last turn off 5G in any way :/

I think you can simply turn off 5G from the settings menu. (You can also set Prefferd Network type to LTEOnly from Radio info... *#*#4636*#*#)
The sad thing is that you can't fix the band in Network Signal Guru (or any other APP).
This may be difficult to do unless Google provides a development tool that supports Shannon modems.
The above looks like something different, aiming more at 'by region or country' to me. Not the traditional band selection found in other devices. It'd be nice to find out if we can systematically program these to hunt on certain LTE/5G bands. I am on a tmobile migrated sprint plan on my p6p. It works great except for that fact that where I live band 26 is garbage. The only solution realy is to find that sweet spot when it swaps to 25 or lock it into the device. So would be nice if the google momos release it, you know, in the spirit of open source, like they initially set out to do so many years ago when android started.
good news everyone. version 4.0.4 of Network Signal Guru has band locking for the pixel 6
