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?

Does nothing. When I hit send it just says invalid mmi code.

I can't say anything for sure until I get about 1 week of uptime with no plummet. It's been stable (battery and signal) since I enabled it, though.

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.
If I'm on t-mobile, should I have my phone set to GSM/WCDMA, or both?
it depends what you prefer do you use data often or are you a just a texter small time web browsing few calls here and there i would leave it at gsm (2g) wcdma would be 3g/4g kicking and rocking all day long so it all depends what you prefer i have mine on wcdma but when im not using it i just put on 2g because it saves battery

Ah ok, so WCDMA is the 3g/4g service, but 2g is E? Would that open up using other network towers, suhc as ATT while roaming?
yes it will show those networks sometimes so if your phone is unlocked you would be able to use it on att....just would need to swap out the sim card if you do but if you are on tmobile it would not matter because they would only go the network that is clicked when you go into network settings

The OP3 does work on Verizon, however there are some "issues" that can probably be easily fixed by someone who knows what they're doing (aka not me).
So far I can confirm 1X/3G (eHRPD) works. I have to enable data roaming for data to work, but I can make/receive calls, sms, mms, and cellular data.
I've also been able to force a connection to LTE by placing the phone into "LTE Only mode". However, when I do this sms, mms and calls don't work (only data works).
For some reason the phone defaults to 3G rather than 4G even though it can use both.
3G/4G data, sms, mms and calling are working, they just aren't working together.
I have done a lot of testing on ,apns and build.prop edits but I have not made any progress.
My personal theory is that the phone is defaulting to a US Cellular APN which then attaches to Verizon's network as a roaming partner.
I really need some help from the community to get this thing working right. Any help would be much appreciated.
I just wanted chime in and say I'm also on VZW and considering picking up an OP3. From reading your other thread, as long as I have XLTE/Band 4, I should be able to at least get some use out of the phone, correct?
The idea of unlocking Band 13 sounds like a fun challenge I'm willing to try!
@notjaykay I tried to unlock b13 but the nvram would reset after boot. Here's the link http://forum.xda-developers.com/showthread.php?p=67648238
I haven't tried to get LTE working, but I've been using Verizon on my OP3 for a week now. Most of the time I use Verizon only for SMS, MMS, and calling, but on several occasions when I don't have T-Mobile LTE signal, I switch to Verizon SIM for data, too. I only get 3G in this case, but it does work pretty well (albeit slow, at 3G speeds). I'm also interested in somehow getting the phone to play nicely with Verizon's LTE.

I just made this change but I don't get Verizon LTE signal at my house, so I'll have to wait until I'm at work tomorrow to actually test it.
That build.prop edit will not get you LTE. I suggest using this app https://goo.gl/620Kc7 and setting it to "LTE Only". You may have to toggle the "turn radio off" option. Be patient and it will work. What you will find is that when in LTE only mode you will only get LTE data. I do all my calls and SMS/MMS using my Google voice number so I don't need traditional voice/sms services. However this is the point of this thread. For some reason the op3 defaults to ehrpd (3G) rather than LTE. Until volte gets working (doubt that will be anytime soon) we will reply on CSFB (circuit switch fallback) for voice and text. Not ideal but a lot better than what we have now.
I did find this folder with a .mbn file in the OSS firmware folder which shows volte config specifically for Verizon (check the attached screenshot)
Thanks for the info, @cdkg. I wasn't optimistic about the build.prop change having an effect, but it was an easy enough thing to try just in case. Unfortunately, in my case, LTE-only is out of the question, at least for now. I'm leaning toward porting my number to T-Mobile to give them a real try for a couple months anyway. However, if this whole compatibility with Verizon <=> OP3 thing ever gets totally worked out, I'd probably come back to Verizon.
I am using a HTC 10 phone au kddi Japan variant. Got success in converting the phone to international but have been rocking custom ROM for a while already now. Bootloader unlocked, S-OFF (obviously). Been running the custom ROM Viper ROM ok for a while but when I converted to the WWE this strange bug happened. I got data, LTE, good connection but no call or sms and it said No service despite the carrier showing up in the menu. Huge thanks if anyone can help me
I got this OP3 that made me change it to the HTC 10. The Problem of it may give you an explanation.
It couldnt Lock signal on LTE and was returning to Edge So you had to press *#*#4636#*#* and select the Network type to LTE only.
However although the phone locked LTE for good then it couldnt make any phone calls or txt msg.
I had to choose LTE/CDMA or LTE/GSM
In Order to change while in call to Edge or "H+" Network.
I guess by that we understand that LTE is only for DATA and not for Voice calls and txts...?
Hope i helped...

Hello, first of all I want to say that my native language is Spanish and I am using the Google translator to write this, so there may be writing errors and apologize.
Buy a motorola edge x30 and the imported import from China. The phone is unlocked to be used with GSM networks from anywhere in the world. When I bought it, I was with Metro PCS but in Metro I was told that the phone was not compatible with the 3G networks of them. After that I started to investigate and find a web page called kimovil and there I saw that the edge x30 was compatible in the USA with all the networks of 3 suppliers: Cricket, AT & T and T-Mobile: I choose to use change to metro by T-Mobile.
Immediately I left the T-Mobile store after making the change I have tried and could receive and send SMS, receive and make calls, and get access to the Internet without any problem. After a couple of hours of having activated services with T-Mobile, the phone could not or receive more calls (the Internet and SMS continue to work normally, the problem is only with calls). When I try to call someone, the call is not done and says "Hanging Up". I tried everything: Factory Reset, Networks Reset, modify network configuration, everything ... and I can not solve the problem. I went to T-Mobile to tell you about my problem and they tell me that the problem is not them but my phone.
If anyone knows how to solve this problem, I would greatly appreciate the help because I feel frustrated. Thanks

Good afternoon. I already managed to use the Edge X30 with the T-Mobile network. You just had to put the network selector on automatic so that you can use 5G, LTE, 3G and 2G as you see fit. The problem is that I realized that the phone only calls and receives calls in 3G and 2G, which limits not only the quality of the calls but also limits your coverage to be able to make calls since you can only make them in 3G and 2G . You who also use T-Mobile, does the same thing happen to you?
I'm not sure, but it supports 5G in N1/N3/N5/N7/N8/N20/N28/N38/N41/N78 and 4G in B1/B2/B3/B4/B5/B7/B8/B12/B17/B34/B38/B39/B40/B41. or check volte settings.
you may try to install "carrier services" app by google from the play store. it solves some of my problem with data connection.

Yes I have the same issue. Whenever I make or receive voice calls, the phone falls back from LTE to 2G. I looked everywhere on the phone for 'VOLTE' settings but could not find it. Does VOLTE work for this phone on Tmobile? Very frustrating.
Has anyone been able to find the solution for the calls switching back to 2g? I love the phone but this is extremely annoying. I'm on T-mobile. Thank you
