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.
Can't post in the development forum yet so I'm asking here.
Just curious if anyone has reported any issues with connecting to the new T-Mobile LTE network with this ROM (Wicked v2 for T-Mobile S4)? If I set my phone to only connect to the 4G network, it has no problem connecting. However, whenever it tries to switch to the LTE network, it won't connect again unless I force the phone to connect to a 4G or slower network. The LTE network connection worked fine on stock.

Yea, that fixes the problem. Thanks for the info. Also, make sure you reboot after adding the APN or it won't connect to the LTE network.
Especially with this community pay attention to apn type in new settings I appear to have been able to thwart the tethering block with v2, appears they did away hiddennapn or Nick was able to kill it in the build.....will continue to test before I say for sure but im getting native tethering and 25+mbps up and down speeds on the m919 (tmo s4)

I have been able to tether over HSPA+ (IPv4) since forever no problem. But recently, LTE service has been expanding to where I am.
In order to connect to an LTE tower, I must use IPv6 APN fast.t-mobile.com
But tethering doesn't work on IPv6 connections.
Has anyone been able to figure out a way around this dilemma?
I use IPV4 on LTE, I don't understand why you "have to" use IPV6?

Could you tell me which APN you are using? I could not sign on to LTE using EPC V4 or V6 or V4/V6, nor fast on V4.
Could you share a screen shot of your APN settings?

I'm having the same issue. I had no idea / am not sure that it is related to the IP version one uses. There is however an interesting document in the nexus lte forums with exactly the same problem and more importantly, a solution. The discussion is here: http://forum.xda-developers.com/showthread.php?t=2044870 with the solution posted on page 2 (my guess is we'd have to adapt it for t-mobile specific apn settings) the script code is here for quicker / shorter reference http://forum.xda-developers.com/showpost.php?p=34662473&postcount=11.
Update! since posting this, I tried under the apn settings for fast.tmobile.com changing the ip version from IPv4 to IPv4/IPv6. now it's letting me tether no problem I'm on the latest jedi master rom btw.
hi! i am new here. i would like to ask a few questions regarding my samsung galaxy note 2 shv-e250L. pardon if some of the questions have been asked before, it is just i am new and i would prefer to make a new post so my questions would be specifically answered on this post. hopefully, you would all be kind enough to answer my queries. i would be very thankful.
anyway, here goes:
i have opened the hidden menu of the phone and it led me to this- please look at the following:
network setting/1. network mode
automatic
wcdma 1900
wcdma 2100
wcdma all
gsm 900
gsm 1800
gsm 1900
gsm all
lte b5
lte b1
lte all
since shv-e250L has the 850 and 2100 bands as mentioned in wikipedia , so i will only be able to use an lte capable smart sim which is being offered to prepaid subscribers. however, my questions regarding this screenshot are these:
a. what if i won't choose the automatic preference and change it to any of the choices, will it affect my lte signal?( that is if i am going to use the smart lte sim)
b. what do those lte b1, lte b5, lte all signify?
c. what does wdcma and gsm mean? what do they pertain to?
d. if i change any the choice from automatic to any of those, will it affect my text and call? or just the internet on my phone?
please look at this too. the following are:
lguhiddenmenu
1. ims volte settings
2. ims volte sip reg
3. ims volte error table
4. ims volte roaming setting
a. what does volte mean?
b. can i change any of the settings here?
c. will it affect the text,call, internet of the phone if i change any of the settings?
for example, look at the following:
volte setting/1. ims volte settings
lte/3g server dns is pcscf1.lteims.co.kr
wfi server dns is wifi.lteims.co.kr
server ip is 10.113.13.75
server ip2 is this allows you to enter a string
server ip3 is this allows you to enter a string
lte/3g-dns or ip(1=dns) is 1
wifi-dns or ip(1=dns) is 1
pco is 1
server domain is lte-lguplus.co.kr
lte/3g server port is 5060
a. can i change anything above?
b. these addresses pertain to korea, can i change these and will it affect the call,text, internet on the phone?
c. or should i just leave it?
i have been reading some posts about flashing shv-e250 models with different roms. i do not know anything about flashing or rooting because i have not tried it ever on my phone. so far on some posts, some users like the rom n7105 for the note 2. i would like to ask some questions about this.
1. if i flash my phone with the n7105 rom and install the kernel appropriate for the shv-e250L, will there be changes on the phone? can you give examples? will there be functionality of the phone missing like vibration, or etc? most of all, will the phone lag?
2. follow up to number 1, i want my phone to stay the same actually,that is with the same functionalities with the shv- e250L and i am contented with it but i just want to make the sms character count to 160 just like the regular phones(i tried handcent, sms pro, but sometimes they won' t even send more than 160, it is inconvenient); remove those korean apps because i won't be able to use them anyway; everything in english since i do not know korean; be able to see my phone number and the network provider in the settings. that is all. as for the rest, i want everything to stay the same. is the n7105 rom capable of these things and still have all the functionalities of the shv-e250 L?
3. what does kernel mean and what will it do to the phone ? in this case, changing the kernel to the kernel provided in this site for korean note 2s.
4. in wikipedia, samsung note 2 n7105 has bands 800,1800,2600. if i flash the phone with n7105 rom, will it have these bandwiths too? or the bandwidths of the shv-e250L will still remain even after flashing with n7105?
5. if ever there is a new update for the shv-e250L, how will i update since the rom is already n7105? or should i update using the n7105?
6. if i decide to change back to shv-e250L, how will i do that?
7. last question, i have kies on my computer, and downloaded some apps for the note 2. the shv-e250L is not recognized by the samsung appstore ph. is it because it is a korean phone ?? i tried switching to samsung appstore korea but the language i do not understand. if i flash it with n7105, will it be recognized by the samsung appstore ph as n7105? or what country- samsung appstore us or what particular country i mean? and will i be able to download apps now from the kies on the computer.
p.s. there are times when i do not use internet on the phone and since the computer at my house has internet, just dsl not wifi, so i use that in case someone will wonder why i just don't download using the internet on my phone.
this is all for now. thank you so much. for those who are going to answer and render patience, thank you.
pardon moderators if i made a mistake in any way regarding posting.
have a great day everyone!
any one? help please
You waited 10 hours to ask why no one had followed up? Patience is a virtue my friend.
You can pay with those settings if you want, but there is also a good chance you might break your phone. The menu's hidden for a reason, you aren't going to be able to activate lots of amazing features.
The answers to almost every question you've asked are to be found in these forums already. Spend a bit of time reading and searching.

EXACTLY.. plus am I correct in saying that the op will only get an LTE signal if its carrier supported. In which case if you leave it on auto in the settings he will get the best signal at present with the present carrier hes with... ps I wouldnt mess with any of those settings unless your completely 100% sure of what your doing..
Also as this is a question and query it should of been posted in Q and A section.

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.
