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.

Hi everyone,
I'm reasonably certain that this isn't a redundant thread -- at least, none of the discussions I've read have helped me fix my problem. Anyway, here goes:
I have a new i9250T that I purchased through Amazon. When I got it, I popped in the SIM card from my Nexus One (both SIM and phone acquired in January 2010). Everything worked fine, EXCEPT that I could only connect to T-Mobile's 2G network (Network Type = Edge:2). After trying everything I could think of, I called T-Mobile, and the tech told me that my 2-year-old SIM card was 2G only and that I should update it. So I went to a T-Mobile store and got a new SIM. Alas, it doesn't seem to have worked.
I would REALLY appreciate any suggestions. Some additional info:
-- I'm in Philadelphia, in a very good coverage area.
-- I flashed yakju, 4.0.2, and UGLC1 radio before getting the new SIM.
Again, any thoughts will be appreciated. I've seen enough posts on various boards from people successfully using this phone on T-Mobile to not give up, but I'm out of ideas.
check what your APN settings are on your N1 and make sure that they ate the same on your GN.

Weirdest crap... aren't the GNEX suppose to work with either GSM Carriers 3G? From what I read lol ...
- Google Galaxy Nexus
I get 3G/H with my Nexus. Running Android Revolution HD 3.0 w/ franco's kernel. Not sure if I got it before then running stock, though.
It should definitely work no question with little issue. Just pop in your sim and good to go. Maybe its some random network issue in your area that coincidentally started?
Same here, got it on Amazon. it's a GT-I9250T which means it's for the Australian market (I9250 International, I9250M Canada, I9250T Australia). I'm just stuck on EDGE, but works fine on AT&T - I tried it with my gf's sim card.
The problem is with the frequencies. T-mobile uses 1700 and 2100 (both! for upload and download), AT&T uses 1900Hz. The phone is supposed to be a pentaband phone that's able to work on all on the freqs besides others (850, 900). So my guess after a few days research is that it's limited in the software. Still researching the solution...
Let's keep each other posted on this, i'm eager to get my 4G back !!!
NEW DEVELOPMENT!!!
Information from another post: flashing UGLC1 radio helps. Good luck all
I had the same issues with no 3g speeds on any radios except a random docomo radio until today.
Based on a few posts in the baseband thread i tried the settings in the hidden menu
Go into the phone dialer and type
*#*#4636#*#* -This should bring up a testing menu
Go into phone info, then pull up the settings menu
There should be a select radio band button
Try the USA band, if that doesn't work, try automatic.
This worked for me, I've since flashed 4 different radios that hadn't worked previously and now do at standard speeds vs edge only.
Well my buddy bought his also from amazon and had the same issue as the OP. But luckily we got it fixed. I believe what he did was only tinker with the APN settings. Under APN Type in your T Mobile apn make sure the correct profiles are there. One of them could be data but I'm not sure as I'm on SIMPLE Mobile and my buddy is on T Mobile, sorry. If you get it working and your MMS isn't working, then add mms to the profile as well. That should do it. He did get his phone with 4.0.1 and I updated it to 4.0.4 Android Revolution 3.0 just like me as well but it wasn't until we tinkered with his settings did it work. Oh and we also swapped for a new SIM. Let me know if this helped guys. I'll try getting his settings if I see him tomorrow.
Edit: his was also an Australian galaxy nexus. But he seems be having everything working now

So ait this is the Australian version? They use 850 and 2100 bands so is it possible the other bands are disabled on that version?
Problem solved!
I took chimaki1's advice and fiddled with the radio band setting. I had done this previously, but I had always selected "USA Band." This time, I selected "Automatic." Closed out of the Testing menu, and -- bingo! The wonderful 'H' appeared and I was now getting real speed -- 7.9mbps down, 2.8 up. Not as good as some of the insane speeds I've seen posted by GN owners on T-Mobile, but a lot better than 100kbps down I had been getting. Also, I didn't mess with the APN settings at all.
To recap the solution for others having the same issue:
From the phone dialer, enter *#*#4636#*#*
Tap "Phone information"
Tap the Settings icon at the bottom right
Tap "Select radio band"
Select "Automatic"
Close out of the Testing menu (you can just hit the Home key)
I can't remember whether I had to soft reset or not; I don't think I did.
I hope this works for others. Thanks very much to everyone who posted.

This is weird. my galaxy is still not getting 3G/4G Service even after changing radio band in the hidden test menu.
Is your galaxy running the stock software, or are you running something different. if so, what rom are you running
It's running the yakju image and OS version 4.0.2. I flashed both using the WugFresh tool. The phone came with yakjuxw (I think) and 4.0.1.

Not "disabled" but more like they're set up to "prefer" the Australian bands.
I'm having the same issue on the I9250T I just got. Stuck on edge. I played around with the hidden menu settings, still no luck. I'm using a TMo SIM card from my previous phone which had 4G so I doubt that its a time/patience issue. Any help will be appreciated.

Today I tried a friend's ATT SIM and it worked fine with H/3G speeds. popped the TMo SIM back in and I'm back to EDGE. Wondering if there is something that needs to be done to the phone settings or, or I was hopping some one could tell me what needs to be done.. thanks
Hi everyone,
So, I've got an interesting issue, and I realize that it is likely my fault. I was flashing various ROM's (CM10, CM9 etc) on the phone, and eventually when I put the stock ROM back on, I was only able to connect on "EDGE". I called Rogers and they said my account checked out. So, I did more ttroubleshooting, and in that I noticed that my IMEI was set to "0". So, I found a guide on here to re-add the IMEI using QPST and I was able to get back on 3G, but no 4G/LTE. After rebooting and some time passed, I am now on 4G, but no LTE and this is my issue. Before you say 4G is LTE, I tend to want to disagree. I used to get LTE, and I did see it pop up once since I fixed the phone, but the phone crashed and i wasn't able to test it with LTE running. Since then, I haven't seen it again. I also ran the "Phone Info" app, and if I set it to LTE only, I never get a data connection, even after rebooting, pulling battery etc.
Why I think 4G is not LTE is because when I ran speedtests before I broke my phone, I was getting 28MB down, and 8-10MB up. now, I'm lucky if I'm getting 1MB down and .2MB up. I have once gotten 4MB down, and .8MB up, but this is WELL below LTE speeds that I've had in the past.
I'm hoping someone might be able to help me get back to a 100% clean, stock ROM, modem, firmware etc. I have installed 2 different stock ROM's that I found for the Rogers i747m; one is ~700MB, the other is 1.2GB. Both have the same issue with 4G only. I've also flashed the stock Rogers modem, and still no luck.
Any help would be appreciated, but here are some specific questions if you can help.
Does anyone have screenshots of their stock "about" page, and the "status" page in the phone menu?
Does anyone have a bone stock "complete" firmware/ROM for the Rogers i747?
Is there anything I can do to fix this on my current ROM (stock)?
Thank you!
Here are the threads I've reviewed and followed to try and resolve the issue.

So, here's something a bit more interesting. Just before bed last night, I caught my phone on the LTE network. I tried loading a few pages/apps, but nothing was working. AFter about a minute, I lost all data connection and it popped back up about 10 seconds later back on 4G and was working again. Not sure if this helps anything, but I did grab a screenshot when it was on LTE.
Anyone?

Thanks for that thread, but does anyone know why the person is removing the SIM and going through all that trouble when rebooting does the exact same thing?
I have used the #2263 menu to set my phone into LTE only mode, and I get no data connection, nor any cell connection either. Switch it back to Automatic and it jumps right back on 4G.
It is faster to remove the sim and enter *#2263# code lol. Once the sim is removed, a no sim notification should appear. Better than waiting for you phone to reboot.
I will post my lte apn setting for you. Hopefully that will help.

Just fyi...
I also have a Rogers S3 and noticed that I am not getting the LTE icon on the notification bar after the first week. Now, I only get a 4G icon in GSM, HSDPA, LTE mode, and 3G/H+ in GSM, HSDPA mode.
However, with the 4G icon, I can still get speeds of 30Mbps down, 13 Mbps up, and under System Information, it shows LTE in Network Type.
My conclusion was that dont rely on the icon in the notification bar. Check the system information page to see the actual network type.
The only time I can get the LTE icon to actually show when I am connected to the LTE network instead of the 4G icon is through re-flashing the ROM. I have tried clearing the cache through recovery menu and it still wont work.
I know this doesnt solve your issue, but I hope this will help anyone that stumble across this problem.
Cheers
Thanks for posting all of that. My APN settings are the same, except the APN type. Mine is set to "Internet + MMS". If I change it, I am prompted with a menu to choose from and the settigns on yours are not in the list. Basically it has the folllwing list:
Internet + MMS + DUN

INternet
MMS

Also, flashing the Rogers Modem was probably one of the first things I did. I thought that would have been most likely.
My mobile Network type is UMTS:3 and I am definately not getting LTE speeds. I've heard people say that they only see the 4G icon, but get LTE speeds, but I'm only getting about 5down, and less than 1 up. I say that when I was on another ROM, it showed 4G, but seemed much quicker. Now I'm just hosed.
Out of curiosity, under the system settings, what do you have listed for ERI Version and IMEI SV?
Thanks!
Any other ideas?
Mine show ERI Version: Not Available
IMEI SV:01
Hope that help you.
Side note: I also note that for reasons of economy of battery when I switch to GSM network and I want to return to the lte network, it takes a long time to show me the lte icon....it's seem to stuck a few minutes on the edge even if gsm/hspa/lte(auto mode) is selected.

Side note: I also note that for reasons of economy of battery when I switch to GSM network and I want to return to the lte network, it takes a long time to show me the lte icon....it's seem to stuck a few minutes on the edge even if gsm/hspa/lte(auto mode) is selected.

Thanks...those settings are the same on mine. Those are the only ones that stand out to me.
Thank you!

I ran through every post in that thread, but still no LTE. Man this is driving me crazy. I'll pay someone if they can help me get LTE back... I've already restored the QCN info using the QCN creator posted in one of the threads.

check peoplearmy's thread - he added info on how to also restore data. if you have having a problem, maybe don't use your own qcn, generate one with his method and restore that. Worked like a charm for me.

I'm pretty sure I did that...but you have to use your own QCN to generate the new "injected" QCN. As far as I know, it doesn't generate one out of nothing. Unfortunately, I didn't have a QCN generated prior to breaking it. Now the "original" QCN I have is "broken" so when I inject it, it's injecting into a broken QCN.
Something I was curious about doing was getting another Rogers S3 QCN (from a willing XDA member), modifying the IMEI and injecting that back into my phone. Not sure if that would break things, but it might be worth a shot. I'm pretty desperate at this point.
Anyone willing to send me their Rogers QCN, so I can replace the IMEI, and inject it into my phone? Worst case the phone blows up, best case I get LTE back, or just restore my current "broken" QCN.
Thanks!
So...I am now fairly convinced that it actually is a hardware issue and not a software issue. I noticed that it was on LTE again (4th time in a week). I was outside walking my dog. I checked tosee if it was working, and out of shock it was! I then downloaded and ran speedtest...got 28down, 9.5 up. BAM!
Now, here's the kicker. I am in a zone where I've always had 4 bars of LTE, except now I can only get it outside. I checked the signal and it was at 62dbm. Walk inside my house, and it jumps to 87+ dbm and drops LTE. I've always had full LTE signal in my house, work, everywhere, now nothing. Based on this, I am certain that the antenna/radio is pooched. Now I have to either get it repaired or get a refurb...ugh. Giving up my month and a half old phone for a refurb really blows...
I am with Telus, and having the exact same problem (minus the IMEI thing).
I flashed to CM10, and my LTE stopped working. Went back to stock, and it's still not working.
Setting phone to LTE only gets me no signal.
I've tested it in Toronto, Mississauga, Barrie (all LTE capable) and nothing is working.
Apparently, it's an issue with the phone. Search Google for Galaxy S3 radio issues (or swap radio for signal) and there is tones of threads. I have a refurb phone coming from Rogers this week, and I'm gonna leave it at stock. Really sucks...but LTE is the bomb.
I read on one thread that Samsung is supposed to push a code fix for the modem, but that's from a bunch of people speculating on the issue. How true it is...time will tell. I'll post back if/when I get LTE back on the new phone.
So, I just got the new phone and LTE is back working everywhere it used to with full signal and full speed.
I hAve this now too...but it's just the icon as I am getting LTE speeds.
Might call Rogers too...
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.
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?

Here is a thread that talks about RAT restrictions. It appears to have to do with restricting access to certain bands, but I am swimming in waters that are deeper than my skills will allow.

I gonna do a run for this later today to see if it will actually work for allowing band selection and sticking.
It seemed to work for me, but it's only been a couple of minutes so far after turning off LTE. BTW, the first menu is "UMTS", not "Units".

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.

I have been testing this for the last 4 hours and it does seem to work. Went to 2g only area and it switched perfectly to 2G and reverted back to 3g when I left the area. However I am not able to do GSM ONLY (2G only) using this method. You will have to follow the instructions on this thread for that.

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
For those of you have LTE connection issues when in the past LTE worked fine I want to share what I did and it worked. I am not in a Spark area and after getting the update from Sprint I lost LTE connection at work. I previously had LTE a 100% of the time at work. I noticed that a lot of folks on the Sprint forums were having the very same issue. After researching with Sprint to solve my problem (They were no help at all), and the combination of things I read here on xda (I can't find the forum So I take not credit for this) I want to share the solution that worked for me.
1. Call Sprint and obtain your MSL code
2. In the phone dialer enter ##3282#
3. press LTE and enter edit, Enter MSL code
4. Click on LTE, then bands 26 and 41 and disable both of them
5. Phone should reboot and LTE should work as it did before
If someone would be so kind if I can't find the threads on here I would like to link them and give credit were it is due.
I just wanted to share what worked for me.

Just a note if you get a profile or prl update that you did not initiate you will have to turn off bands 26 and 41 again following the steps above.
Disabling bands 26 (800mhz) and 41 (2500mhz) seems counterproductive to the gains that Sprint Spark is supposed to bring. I'm guessing it's probably region specific to those having LTE issues where disabling these bands "fixes" whatever issues you're having (maybe Spark is not fully deployed, etc). I'm not having these LTE issues by the way, and LTE coverage here in NYC has improved to the point that i even get LTE in some underground subway stations.

That's the exact problem, the roll out is far from nation wide. So if you are in a non spark area, the phone constantly seems to search for it. My battery life significantly decreased on ZVC. Once I shut off those bands, my LTE was much more stable and battery life improved greatly.
