[How to] Disable LTE or 4G

This is useful if you have a weak LTE signal or just don't need it always on. I found this tutorial on a different website for another galaxy phone and it works on the Note 3.
1. Turn off your phone and take out your sim card.
2. Turn on your phone with no sim card and wait a minute or two for it to turn on and settle down.
3. Go to the dialer and dial *#2263#
You should see a menu with band selections. The current setting is "Automatic".
(You have to use the menu key to select your options by using "Key Input" to type the number you want)
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) Power off the phone again and put your sim card back. Upon reboot you should see your new setting in effect.

I get a service mode that says rat selection is restricted...
However *#*#4636#*#* will allow you to select whatever band you so choose. Although lte only doesn't allow voice calls

If your sim card is out when trying to access the menu it shouldn't say restricted.

I tried the above on my S4 and couldn't get LTE back was stuck on wcdma preferred. Google resulted in a ton of information. Ultimately hard reset needed.

Yeah that code doesn't work for me. It never worked for my note 2 or note 1 so I wouldn't recommend doing it.

Sorry about your luck with it, I've never had a problem using it to switch between lte, wcdma, or gsm on my s4 or this note 3. Weird...

Thank you inmotion! This code actually worked better for me on my Samsung Galaxy Note 3. I didn't even have to pull out my SIM card or reboot. Just dial in the code, go to Device Info and change the preferred radio network type. It changes the radio on the fly in real time, and can be seen at the top.

Since Android 4.3 and on the option to disable LTE/4G has been removed from all AT&T Android devices.

Actually it was before that. Could not do it on my note 1. Would always get RAT restricted. This was on at&t. Other networks were able to use those codes and make the switch.

1. Download the free Phone info app from the Google Play Store and install it
2. Choose the Phone Information tab and notice the "Set preferred network type" option at the bottom, marked with an arrow at the right of the drop-down menu
3. Tap on the preferred network listing currently in use, and choose the "CDMA auto (PRL)" option from the drop-down list
4. You should be now maintaining connection to only Verizon's 3G network, and whenever you need to use data, you can switch back to LTE for the duration of it
There are numerous other apps and widgets at the Play Store that claim to do the 2G/3G/4G switch, but many users on Verizon have confirmed the Phone info app to be the only method allowing them to reliably turn off the 4G LTE on their Samsung Galaxy S IIIs.

why would people want to disable LTE? (real question)

Does anyone know how to do a network reset? Because I connect to any Data at all no 4G LTE or 3G none of those. I can't send or receive pictures and go on the internet. I tired taking out Sim card for awhile and still didn't work. Does anyone know what to do? And how to reset network?

Wifi connectivity problems

Im having trouble staying connected to wifi at home, it stays connected as long as im in the living room close to the router but when i go into the bed room which is about 20ft away it disconnects and then reconnets several times. The router connection is 5ghz and only me and my wife use it.

First, make sure you've turned off "Auto Network Switch" in the advanced section of Wi-Fi settings (go to Wi-Fi settings and press the menu key and select advanced).
Second, turn off WiFi Power Save mode in the ServiceMenu. Go here for directions.

I done what you said i entered the codes you said to enter on my dial pad and it didnt bring up anything no services menus...nothing. but i did go to wifi and then advance and unchecked the box you said to uncheck and waited to see if it would kick me off and it did it still kicks me off wifi while im in my bed room.

If you're rooted, you'll need to go to /efs/carrier/HiddenMenu....
Open the HiddenMenu file in a text editor and change OFF to ON
Maintaining capitalization of the word ON
Save file.
Then reboot. Try those dialpad codes again.

Dial pad codes worked like a charm went in and changed the band to B4Enabled*. Now im gonna hang out in my room for awhile and see if i get kicked off my wifi. Thanks a bunch for you help i just hope this works oh and yes i went to text editor and then carrier and deleted OFF and replaced it with ON then restarted my device then went back into carrier to make sure it saved and all is good. Just hop it fixes my problem. Thanks again.

Now i need to tryn figure out how to make my call signal better....lots and lots of fun this phone is

When it kicked me off before it took awahile before it would connect back. While in the process of typing i got kicked off but connected back veryfast. Strange because im only about 15ft or so away from the router. I have noticed a big difference though, before my bars would fluxuwait from 1 bar to 5b now it usually stays at 5.

Anyother suggestions i can try

Go into your router settings and check/change the frequency(2.4-5) and the broadcast channel to match what the phone is using

Turns off the power save mode worked for me. Thanks. Now I don't want to flash to a custom to anymore. Thanks.

I just upgraded my wifi from 3megs up to 12 megs. Im still having trouble downloading files that are 1g and up. I downloaded speed test.net and checked my down & up down reads 10.92m and up reads 2.23m but when im downloading a file say its 1.25g it slows waaaay down to like .94m is it supposed to do do that? Im the only one connected to my wifi at the moment.

12mb/s is a pretty slow speed. It's going to take a long time to download it. When you're downloading a file the speed you see is Mb/s not mb/s. Megabytes and megabits are a lot different.

AT&T service person came out today and upgraded my internet, from 3megs to 12megs. I asked the tech how fast it would download a 2g movie his answer was, " it should take about 15 mins at the most". Wireless is just a f#@$in scam the co$k [email protected]$!ers will tell you anything so they can get ypur money! The highest they offer in my area is 12megs funny thing about 15 miles from where i live they offer 50megs. Its just a rip off!! Im feed up EVERYTHING IN THIS WORLD IS A MONEY RACKET...MONEY MONEY MONEY......IM SOOO PISSED

N7 LTE and calling. Yes😀

So I remember T-Mobile rolled out WiFi calling. I downloaded Google hangouts dialer and tried the calling feature.
First I connected through WiFi and ran the app and made a call to a ATT cell phone. And it worked. So then I turned off WiFi and turned on mobile data. Made another call to same ATT cell phone and boom! N7 T-Mobile walking talking phone.
I'm stock rooted, google hangouts dialer. I don't know if this works on ATT or Verizon because I stunt have a Sim. My call went over 'H'. I have no LTE connection in my room.
Anyone else want to confirm. But sweet

I thought it wasn't supposed to, because Google locked it down. You couldn't do this before. I don't believe this worked until volte started to roll out. And with Google integrating this into hangouts

It started working when the dialer came out. Doesn't have anything to do with the rollout of volte on some carriers.

The dialer included with hangouts is just a way to connect to gvoice with voip, which has been possible for years with 3rd party clients such as Grooveip
All it does is simplify the process of setting up, the concept is the same.
Literally any device that can connect to the internet can do hangout calls in the same manner, as there's no carriers involved at all. As far as they're concerned it's merely data.
What they did do was disable the method some clients, such as grooveip, used to connect to gvoice.
But there are multiple methods, existing solutions such as obitalk can still connect to gvoice via voip.

I use standard app embedded in my phone by default. I noticed, that for some mobile operators it does not work. I live in Europe and when I try Lycamobile it does not work or work very bad with many delays and interruption. When I insert to the same phone Vodafone simcard, it works perfect. In your case if you can try to use another sim card you can try. At Least you will know, if problem in your phone/software or at&t.
