I live in hilly country where LTE is available on the hilltops, but signal often drops to HSPA or 3g in valleys. My concern is that I will be wasting power while the phone is on 3g and searching for LTE. I don't know if this is a problem on the note, but it is on other phones and I am looking for an EASY way to stay on 3g when not using data. Any solutions?
*#*#4636#*#*
Device information then you can force it to any setting you want. You'll want WCDMA only for 3G only.
Thanks. If I get confused can I back out of this code menu or just restart the phone to return to default LTE operation? Don't want to screw up and get trapped in an unwanted mode.

It seems like people with unlocked devices are able to lock 2g but AT&T branded devices are not. We've all tried these methods and they have not worked:
4636 menu
AnyCut
ProWidgets
The problem seems to be that we can't disable the automatic operator selection. I remember this used to be a problem on the BB but someone figured out a way to enter some type of code into the phone and enabled 2g lock... AT&T also eventually enabled it after a few years. Is it possible for this to be enabled on AT&T Atrixes?
You're trying to lock the device to 2G bands only? I can't imagine why you'd want to do that with AT&T upgrading their 2G towers (albeit slowly).
The problem is I get very weak 3G/H+ signals but strong E signals where I am and it kills my battery when the radio is flipping back and forth and trying to find a stronger 3G signal.

Hey All,
I searched the web on and on and cant figure it out.
My provider Vodafone in holland provides me with 4G.
On some sites i read there is a minor update which activates the LTE option.
that update is for the I9505..
I cant find if its possible to unlock my LTE option.
i have the I9295. And throug kies or OTA is no update
I hope you can help me out guys.

I can't really help you but as far as I know LTE is already unlocked and working on all international S4 Actives. Mine certainly worked perfectly out of the box - although I turned it off promptly because I have ****ty 4G coverage where I live so it was nothing but a battery drain for me.
Are you sure you have a 4G sim card, and that you are in an area where 4G has coverage?
If you go in under settings > connections > more networks > mobile networks > network mode don't you have the LTE option at the top?

Im not 100% but i got the textmessage from my provider, so i recon they only send it to people who are able to use the 4G.
Yes, i am in a 4g coverage area
i dont have the LTE option at the top no. i have:
- wcdma/gsm
- only wcdma
- only gsm

Well then I really have no idea - the only thing I can think of is that you might need to replace your sim card if your provider didn't already do so in advance of the 4G rollout. Hopefully someone with more information might step in here, but the international version is LTE capable out of the box. If you don't hear anything else I'd suggest to try and contact vodafone and get a clear answer from them first.
If you check the mobile networks in your area and don't see anything that supports LTE, you may just live in an area that doesn't have it yet (people get 4G and LTE somewhat mixed up - 4G is the overall identifier for a whole class of technologies with "4th generation cellular networks" basically while LTE is technically one of those technologies so, it should rightfully be classified as 4G in most respects.
Having said that, the only way I got my GS4A to function in LTE mode - meaning it actually shows LTE in the notification bar under the 4 with a small G and LTE underneath it - was to go into the service menu (*#*#4636#*#*) and change the preferred network type to either LTE only or LTE/GSM auto (PRL). Once I did that the radio would reset and connect and then it would be in proper LTE mode. Doing a speedtest with the Speedtest.net app shows LTE as the connection whereas with my standard setting which is WCDMA Preferred (T-Mobile AWS) it'll just show as "4G."
I've had no luck making alterations in the Settings/Mobile Networks section, I have to change it in the service menu to get LTE functional. I don't use it because here in Vegas where I live (specifically my home location) the LTE mode gets me about 1-2 bars of signal (about 8-12Mbps) whereas the WCDMA Preferred setting pulls in 5 bars rock solid and 25-35Mbps.
Can't do screenshots or I'd add them, I'm running the pre-release MI2 ROM presently and that aspect is borked.

That would be because you're on the i537 from ATT, rather than the i9295 that this discussion is about. I checked google and vodafone holland does indeed use LTE on the right bands in its brand new rollout, so it isn't that - most likely it's his sim that needs replacing or it's just not activated on his account yet.
Hey guys
So I looked around the forum for an answer to this question and i found similar topics but not exactly what I was looking for. I have the HTC one with sprint and the only issue I have with it is how it handles its preferred networks. If have 2 bars of LTE but 4-5 bars of 3g its going to stay on 3g and not switch to LTE. Is there anyway to change how it gives each signal preference. Currently it will wait till there is no 3g signal before it switches to 2g but LTE is not giving the same preference. I know it's just this phone because I had the iphone 5 before this and when I was on campus at my university it would stick to the 1 bar of LTE i had rather than switching to 3g. If I force the phone in LTE only mode then it will pick the LTE signal but then I can't call and text obviously so it's not very useful.
There are two things that the iphone 5 did which I miss but otherwise love this phone. One is getting LTE in places that has low coverage and the other is roaming on verizon network on 3g. The iphone would always roam on 3g but the htc one only roams on 2g.
Is there a way to change those things with this phone? Thanks in advance!

Have you tried changing the preferred in the *#*#4636*#*# > Phone Information?
Hi thanks for the response. Yes I have messed around with that. That's how I got the LTE only option. It isn't a matter of not finding LTE signal. It's just the way the phone handles what is perferred. The phone first sees if there is a strong LTE signal and it catches that but the moment it goes to about 3 bars or less it will switch to 3g. I want it to continue sticking with LTE until the signal is gone completely like it does with 3g -> 2g.

I see. And who do I ask for that? Or how can I build one? Sorry I am a bit of a rookie in this. I don't want to mess around with it too much but can learn. I thought there might already be some sort of hack or a modded PRL.
any new insight on this by anyone? thanks
I have lte at my work if I do lte only but it will switch to 3g when i turn everything else one because 3g signal is stronger than lte. id rather use lte however but still have my texting and calling capabilities.

I know it's not an optimal solution, but have you considered using Google Voice integration in the meantime? With LTE only mode, so long as you're signed into an app of choice (Google Voice/Hangouts should be able to handle your calls and texts if you tweak at it a bit), you should have the desired service until you can get some dev help.
I saw a few screenshots of people's Moto X's from sprint with a bunch of options under Network Mode. I have the XT1053 (TMO unlocked, on ATT network) and the only options I see are "Auto" and "2G."
I browsed around and found that there's an LTE OnOff app, but I'm just wondering if there's a way I can get those options for 3G on my device's Network Mode option list?
The reason why I even care is because for some reason at my workplace, I can't seem to get any data through LTE. My signal will display 3 bars of LTE, but it absolutely does not work. While it will turn off LTE and just say 4G since it's on auto, I find that a majority of my day, it WON'T switch. It stays on 4G LTE 99% of the time and does not function at all. When I walk outside the building, LTE works perfectly fine. Would I be right to assume that the auto mode is literally on borderline between switching, so it never establishes a stable connection?
I guess it brings me to the question, is the Auto mode inefficient / will I have to live with manually turning off LTE every time I get to work? :/

3 bars of LTE is an excellent signal. With 1 bar of signal I can still get 15mbps down from my provider. If your phone is detecting such a strong received signal it won't be switching back to HSPA on its own. For some reason the building you're in may block the phones transmitted signal more then it blocks the signal from the cell site. I am guessing you're on band 4 LTE which has quite the frequency difference between uplink and downlink. Your only option(assuming the phone or cell site isn't defective) is to manually switch to WCDMA with a third party app such as the "LTE setting" app in the Play store. Or unlock your bootloader and flash firmware from another provider that has more options. I know the Rogers Canada firmware has an LTE on/off option, it also has a 2G only option. Sadly Rogers has not yet approved the release of 4.4 (kitkat).

That makes a lot more sense to me now. So basically the "Auto" mode only considers my reception and not transmittance strength, so it never saw a need to switch me off LTE. I am almost sure it is not my phone because I started experiencing a signal loss issue with my S3 a few days ago. I doubt it's the cell site because as soon as I step out of the building, LTE works with no problems.
I did ended up using LTE OnOff to force CDMA and I can actually do stuff now. I went and did a speedtest ...
Ping: 114 ms
Down: 4.06 Mbps
Up: 0.77 Mbps
I guess with the lack of options, I have yet another reason to roll up the sleeves and get my hands dirty. Haven't touched ABD since I had a samsung captivate!
Thank you
Guide: How to turn LTE off
Turning LTE OFF can be very beneficial to the end user. Turning LTE off can boost your signal and save battery life in areas of weak LTE signal strength. HSPA+ and EDGE signals travel further than LTE signals. At the time of this writing, AT&T’s HSPA+ network performs very, very well. Most people have switched to LTE. It is very easy to pull 10mbps down on HSPA+. Therefore, if LTE is congested you can try out HSPA+ (AT&T calls this 4G). Some people also like to force the device to LTE only; this way they don't get calls, but can receive texts.
1. Open dialer
2. Dial *#*#4636#*#*
3. Device information
4. Scroll down and then choose your preferred network type:
WCDMA Preferred = Your phone will prefer UMTS/HSPA or HSPA+. Will connect to EDGE if it has to. NO LTE.
GSM Only = If selected, your phone will only connect to EDGE (2G). You will be able to call, text, and use slow data.
WCDMA Only = UMTS/HSPA+ only. No EDGE, or LTE whatsoever
GSM/CDMA Auto= Will connect to either UMTS/HSPA/HSPA+ or EDGE (which ever one is available)
LTE/CDMA Auto = Will only connect to LTE and UMTS/HSPA/HSPA+, NO EDGE
LTE/GSM/CDMA Auto = Will connect to LTE, EDGE, or UMTS/HSPA/HSPA+
LTE/GSM Auto = DEAFAULT SETTING
LTE Only = You will only have LTE. You cannot make calls under this setting. Good for those who want data and text capabilities.
Hope this helps!!!

You will not screw your phone up, no matter which setting you choose. LTE/GSM Auto is the default setting. Once you select your preferred network it will not stick once you reboot your device anyway.

Cannot turn off LTE with above instructions
When I try to follow the instructions, I dial the number and a pop-up appears with "USSD Code Running..." then it closes and a new pop-up appears saying "connection problem or invalid MMI code". I have tried to make this call from various areas with better connections than in my house, but still to no avail. I'd really like to disable the LTE because it is only strong enough to constantly force changes from 4G to LTE and back while massively draining my battery in the process. Any advice?
I upgraded from S3 to S5... In Out location there is one LTE tower.
When at office which is bit far from LTE tower, It only connects to LTE and due to congestion i always get 0.2 mbps only..
But When i had S3, it will switch automatically to 4G(HSPA+) at office and at home or shopping it connects to LTE.
So I called ATT support and they said its due to network congestion and they switched to 4G on their side.
So now its always shows 4G only no LTE but speed are good like 8 to 10 mbps..
I tried the steps in post1 and it shows WCDMA preferred... Is this what they modified remotely?
Try Intelli3G everyone, you have to install Xposed framework and then install it but this app is amazing for convenience.
I tried changing to LTE option its not allowing. I can change to other options other than LTE.
Any idea.. Is it controlled by AT&T?
I called ATT and asked them to change it to LTE.
Now I can change the settings as needed.
So if ATT sets to 4G, you wont be able to switch to LTE.
Is this the only way to change the preferred network mode on SAMSUNG-SM-G900A, ie. by going to details mentioned under #2
Has anyone tried this lately? I know the old 4636 code worked on older galaxies buy I can't get my G900a to respond. Still on 4.4.2
