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!!!

Will the change last through a reboot or does it need to be changed every time the phone is restarted?

Yes. For each reboot you'll have to repeat the above steps. However, I would rather do this, than have to take out the sim each time.

I wonder if a NFC task program can be used to program the sequence into a NFC tag so it can be easily changed each time?

That I don't know.
Thanks! I switched from the default to WCDMA preferred and seem to have a better signal where I live (on a mountain).

Sorry if this is a stupid question but I don't want to screw up my phone. Which would be the default in case I want to turn LTE back on?

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.
Which one is the best?

Probably leaving it on automatic.
isn't there a toggle switch or a widget that you can download from play store to do he same thing? just wondering
+1. Also interested in a widget of sorts. Any ideas?

There are widgets, but they do not work.
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
Work fine here on 4.4.2 and 5.0

I have a sprint HTC one unlocked to run on T-mobile. I live in south west Washington, and I am having a very strange issue with my data. I select a data mode from the *#*#4636#*#* menu, and about half the time I connect to data. The other half of the time, it stays on UMTS, and no gsm logo pops up next to the signal. Other times, I will go to HSDPA, and have a very speedy data connection. Is there any way to disable UMTS? Could this be a rom issue, or a APN issue? I can almost always get an edge connection, but HSDPA is much better to use. I have done the R-UIM patch. I'll try to answer any questions, but I dont have tmobile service at my house, so I cant be sure

You can't "disable" UMTS. From my tests on this variant of the One, setting it to "GSM auto (PRL)" will get me on HSPA. It will keep me on HSPA until the network kicks me off. (Fast Dormancy, it puts you down to UMTS when you aren't actively using data to conserve energy.) [Maybe you can disable Fast Dormancy, who knows.]
PagePlus does not activate an LTE phone on their "low-end" plan but allows a modified LTE phone to be activated. I used an app to make it CDMA only but PagePlus still cannot activate it saying it has some issues because their system still thinks it is LTE. I wonder if I have to something special on the phone.
I unlocked fast boot. The phone is not yet rooted.
Any help is appreciated.
Network connections? Set preffered to 3G/2G.
@kyzn is right with going to Settings > More > Cellular networks > Preferred network type and selecting 3g. This does not mean it will be in 3g only because 2g is there for a backup network signal in case that the 3g or higher signal is lost. Shouldn't be problem for you with what you are asking.
If you would like a little more info here is a link to the similar OP

Grab this app, it'll take you to a menu which lets you select the mode you want.

Hi, I realized that when I turn off the 4G network data the phone changes to 3G, then if I turn on data again it turns 4G on after 20 seconds.
I had tried to use the *#*#4636#*#* method and put "LTE only", it works, but after I turn off data again the setting returns to GSM.
Other phones have 4G network ON don't matter if data is on or off.
There's a way to force 4G network all the time like the other phones have?
Well, like no one has the answer, I had found a workaround:
The app Intelli3g is the answer!
Hi
I'm trying to get the best Internet connection on my phone. My carrier doesn't support voice over LTE so if I set the Network mode to LTE only I got no calls incoming or outgoing.
The other options I have are 2G only or 3G only, which makes my LTE data plan useless.
Best option is to have it configured to 2G/3G/LTE, but the problem is that when I'm usually stuck with an excellent 2G connection (with useless internet), instead of a not lousy/not great 3G connection, which still has better Internet speed and stability than 4G.
I'm looking to have my phone only see 3G/4G and not 2G, but I don't have a network mode for that. How can I enable the network mode I require?
I'm rooted so if I can enable it somewhere in the system, that is an option.
Thanks in advance
