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

You can mix the different bands between wcdma and gsm and their frequencies,that way you can get the best signal in your area.

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.
I just play with my S3 I747 and find out how to temporaly remove RAT restriction.
Click phone then punch code : *#197328640# ->Umts->Debag Screen->Phone Control->Network Lock->Rat_Free_Supporting ON
After you click this you see " Now RAT Free Supporting". Click back button and try setting radio by pressing *#2263#.
RTA will lock back after restarting.
could you explain what "RAT restriction" is and what removing it will provide?

Any suggestions on how to make these changes permanent without rooting?
Since there is now a known code to lift restrictions until reboot, I hope some dev will figure out a way on stock based roms (both stock and mods), as well as AOSP based, to make it permanent. I have tried AOKP and CM10 in hopes the LTE and 2G toggles would work but no dice with AT&T SGS3.

Given the issue at hand, it is most likely a deeply embedded setting that will not be available to standard user base (non rooted), henceforth root access or even on a programming level will be needed to make the necessary changes. How the changes will be made available, if it is done, will depend on what was needed to make it permanent. This raises the question of where is this restriction coded into the AT&T SGS3. Is it firmware, ROM, SIM related, Radio? Seriously doubt it is hardware itself since there are ways to get around the restriction.

Testing this method now. So far I am running on 2G. I will give it at least a couple of hours and will update this post accordingly.
Update: I was messing around and decided to save this USSD (the official name of these secret dialer codes) in my contacts. From dialer you can start pressing *#1 and when it appears just press it. This gives quick access should you need to change radios often. I also want to add that instead of going back into *#2263# you can also select the band from *#197328640#. If you want to change it immediately, then once you get the confirmation "Now RAT Free Supporting" press the menu key on the left of the Home button. Select back and repeat again to go back again. Then, instead of choosing Network Lock choose Network Control-->Band Selection. This takes you to the same menu that *#2263# does and you can select accordingly.
@norbarb...perhaps you can update your OP to reflect that you can stay within the original selection instead of *#2263# and just go back twice to access the band selection. It is just one more way of doing things.
I also did the test of rebooting my phone. As mentioned by norbarb, if you have rebooted the RAT restriction is back in place. Regardless of which option you take to the band selection it will show RAT restriction until you follow the OPs steps again to remove restriction. Have not found a way for permanent removal of the restriction yet (I am optimistic and really want this permanent so I will look very hard to find a solution.). Also when I rebooted I had GSM 2G only selected prior and I kept the option upon reboot so only the RAT restriction is reset...not the network band settings.
Update 2: After 4 hours I am still on 2G Edge. I am in a very good LTE location so this is definitely the most promising outlook. I have found that I despite my love for the look of AOSP roms, the inability to turn on 2G at all will keep me with TW for now. Thankfully I do not mind the look of TW and with root, I can kill the Bloatware. I will look at all of the options in the *#197328640# menus and see if there is anything that may can be applied for permanent access. I also wonder if the secret to overriding the lack of options for network choices in *#*#4636#*#* will be here as well as this would more preferable to shut down LTE only.

Isn't the problem with doing this, say if you disable LTE and only select HSPA, it wont go to any 2G networks if you are out of coverage. Because its not on 'automatic', its on HSPA. So if you are out of a service zone of HSPA, then you dont have anything to fall back to.
If only there was a way to disable LTE, and use the other networks 'automatically'.

That is the problem. However, AT&T in their infinite focus on trying to force users to their networks of choice has purposely had the ability to do network selections disabled. Under normal circumstances in android devices the option of network selection is under settings and mobile networks option. This is removed I am sure at AT&T's request. The other way to access this is to use USSD *#*#4636#*#* in dialer and select "Device Information" which will give you an option to choose a network preference. While the USSD works the option to select network preference does not work.
At least with the option to unlock RAT and using USSD *#2263#, it gives some sort of ability to choose a network. For me this is perfect since I want the 2G only due to poor 3G and LTE signals at work. However you are right that it is not convenient if you just want LTE off. For the moment there is no known way to obtain this option on the AT&T SGS3.

Yep. I also think it's something to do with AT&T network setup. Because on AOSP ROM's we can't toggle LTE either. But the same ROM on a Canadian model phone will work just fine.
Even though the iphone has an LTE toggle. At least I read somewhere that it does.

It has nothing to do with the network setup...it is the carrier forcing restrictions on their customers. I have had three other android phones (including my wifes) in the last three years. All of them were restricted from choosing the network from stock rom. The moment I uploaded a ROM such as CM or other AOSP Roms I was magically able to do a network select. I even had to Windows phones (6.1 and 6.5) and both of them were stripped but with some registry edits I was able to add the option back to select between 3G/2G and 2g only. It is AT&T's way and they are notorious for it.
On a side note, I would not be surprised if AT&T is the primary corporate network that pushed for this network SIM lock ruling by the Congressional Librarian. Of all the carriers they have the most to lose.

It could result in battery savings and reduced dropped calls. For instance, I am often in and out of areas with little to no bandwidths under LTE. At default, my phone would always looking for an LTE signal which means my battery takes a pounding. By having my phone only look for 2G/3G, I do not take as large of a battery hit. Besides that, LTE does consume more power. For the most part I leave my phone with LTE off because the data speed is not crucial for me. At home I have a really fast WiFi network so it is better to be on it anyway while at home.

OK Thanks. But under Settings/More Networks/Mobile Networks/Network Mode there are 13 "band" combination choices. Do those choices not provide what you''re looking for (i.e.2G/3G)?
I've never changed mine, so I'm curious
Hi all,
Been lurking around forums for awhile and have also been helped and taught greatly by the discussions. Just became a member recently and this is my first post.
So I was flashing a couple of roms from CM 10.1 to stock android mod but noticed I couldn't get to the hidden menu *#2263# screen that I had with my default AT&T Samsung touchwiz that let me choose which LTE band to latch on to. I'm assuming this is because this is because all the roms are AOSP-based.
I was wondering if there was a hidden menu option for AOSP-based roms that had the same functionality as *#2263# (only available in touchwiz/Samsung base where you can choose specific LTE bands) instead of just the *#*#4636#*#* (where you can only choose which network but not the exact band) or if there are any apps out there that have this option of choosing a specific LTE frequency band.
I'm in this weird situation where we're testing only the LTE network of our provider and want to block off other fallbacks, etc..
Thanks for any feedback and suggestions.

I'm not sure what you mean by ATT disabling the ability to select individual bands as, with a stock Samsung AT&T rom, I am able to do *#2263# and get to a RF band selection menu. However, with stock Google edition or other AOSP roms, this *#2263# hidden menu is nowhere to be found.

It's the same one that's everywhere online for TMO LTE, it's not device specific, in fact the same settings are used for all LTE enabled phones, even iPhones. I'd be shocked if it wasn't either the 1st or 2nd result after a Google search.

Leave all other settings as is.
For MMS to work, make sure you add "mms" in APN Type field.
Moreover, once in a while, you'll get an annoying popup saying that the sim card is not Verizon etc. If rooted, just use Titanium Backup and freeze the "activation" apk. If not rooted, use Package Disabler Pro, and the disable the aforementioned apk.
Good luck.
the issue is in you are using Verizon S6 Edge+ on Tmobile network, you can't use data while on phone call.
it doesn't pickup band 12, only works on band 4 etc, which loose the data if phone call picked up.'
is there any way around?

My note 3 did this going from verizon to tmobile. A workaround i found was to switch the network settings from 4g or global to 3g or 2g only and then make the call. Touch tone would work, then after hanging up switch network settings back to 4g or global. Hope this helps you.

I've noticed since I've locked my phone to only one lte band and one h+ one... My battery has significantly got better... I have the SN-N970F DS... Not sure if the snapdragon version allows this yet but the app I used was quick shortcut Maker. It's a lil process to get it going but once it's on its great.

NOTE: THIS ONLY WORKS FOR EXYNOS. SNAPDRAGON DOES NOT ALLOW THIS WITHOUT ROOT.
Once in the app... Go to "call settings" then to the last call settings option... Then tap try on the next screen. Then go to the menu option in the next window. Tap band selection.
It's a bit of work to do but:
Have speed test app
Have the call app also ready to be used.
Have cell tower info app (any that shows current lte bands)
Run the speed test app and monitor the lte bands and see which bands are better in your Area. This way you can lock to which ever works best for you.
The reason for the dialer app is to see which WCDMA is needed for calls. You have to have one on that works for you.
Once you determine which lte bands (best to chose 2) and which GSM band your carrier uses for calls... Tap the selection toggle.

Thank you. Seems to be working well. Will have to test for a while.
I am not concerned on using mobile data, i have wifi most of the places. How can this be helpful to increase the battery time? I have dual sim and as per cell info, one sim uses Band 3 and other sim uses Band 20 currently. What steps i have to take to lock in the best band to reduce my battery usage?
I have the steps in my previous post. With a combination of the cell tower info and speed test app... You can determine which band yields the best results. I'm still testing this myself. So far I've gotten just a little over an hour extra. Not much but just like to test this out. Dual SIM users is a little more tricky.

1) Going to the Phone App?
2) What is the "last call settings"? Can't follow the guide.
It's just the last option that says call settings

Settings ( GENERAL ) >>> Connections >>> SIM card manager >>>General settings >>> Network mode...
and then choose which band You want to prefer... You can choose to use only lower band like 3G/2G but, in my opinion, it's not worthy cause it decrease network speed pretty drastically and You get up to 1 - 1.5 hour better battery life...
OK i found it but I can't change it (it is grey and I can't click). Thanks for the help!
I mis read your post... I'm in the quick shortcut Maker app... Not the phone app
