It is easier to just type "*#2263#" in your dialer because it takes you directly to the network selections you are referring to.

Some carriers use restrictions (RAT restrictions) to prevent this.

In this case..such as with AT&T, you would dial *#197328640# and go to UMTS>DEBUG SCREEN>PHONE CONTROL>NETWORK LOCK>RAT_FREE_SUPPORTITNG ON (supporting is misspelled with the last T and I swapped around). After this you can use the OP method or from the dialer type *#2263# which takes you directly to the band selection options. Whenever I was running stock rom, I used this method all the time. The one catch with RAT restrictions is you have to redo the option to unlock the RAT every time you reboot.
There are four options under band selection: Automatic will allow for LTE, 3.5G, and 2G depending on what signals are available. However if you choose one of the other three options, it locks into that particular bandwidth. If you choose LTE you will only have data capabilities since LTE does not currently handle voice calls. If you move out of an LTE area, you will no signal. The same applies to all except for automatic which switches between bands as needed.
On the other hand if you are trying to disable LTE only, then there is a completely separate method of doing this (assuming that network preferences does not work). Create an APN and just name if Fake. Once created, enable it and exit and go to dialer. You will lose data, but this is only temp. You must wait about 25 seconds then dial *#*#4636#*#* and choose "Device Information". You will see a dropdown menu that says "WCDMA preferred". Change this to "GSM/CDMA auto (PRL) and exit. Go back to the APN settings and switch to the one that works for LTE. However, you will now only have 2g and 3g capability with LTE disabled. This will last until reboot, airplane mode, or an option is chosen from one of the dialer methods selected above (normally, the selected bandwidth under the dialer method contains a * next to it. When disabling LTE with the APN however, when you go into it none of these are annotated with the *. You are effectively "tricking" the phone to work the way you want it.)
Correct, and sometimes if you lose lte you can re select all the lte bands, then automatic, and you'll regain your lte
I have seen a few postings mention this.
Dial *#197328640#
This brings up the debug screen (service mode)
I unlocked my T-mobile Samsung Galaxy S4 and I am trying to use it on an AT&T mnvo but I do not get any data service. So I am wondering if the bands need to be changed in this menu or some other menu on the phone?
Does anyone now this information? I am trying to determine the cause of no data on my Red Pocket sim card. I have the APN Settings correct and registered on the Network but still no data connection.
I've scoured the internet for finding out to enter the service menu on the note 7. It seems that the s7 and s7e have been figured out, but no one yet seems to have been able to actually enter the service mode the note 7.
I do know that the service mode application opens if one dials: *#0011#, but I cannot enter further into the application to change LTE bands and what not.
In past Samsung phones, one could further enter the service mode by hitting:
Menu -> back
Menu -> key input -> Q
Menu -> key input -> 0000
Wait 10 seconds
This method does NOT work on the note 7...
Now while this may be a larger issue, I cannot get AT&T LTE enabled on my device. I have the N930-FD from Singapore. This is why I'm trying to access this hidden menu.
On key input type in: Q0
And wait 10 secs.
Still not working.
While I follow the procedure, there is no response. It still display the network information.
What is the whole procedure to operate?
Did you have any finding regarding how to change LTE bands?
Does this work?

Please help.. Is there a way to set network mode to 4G only or LTE only?... In settings, I only have the Autoconnect, 2G only and 3G only options.. Thanks..
Is your SIM card already 4G supported? What's your carrier?
The 4G auto connect is available? Apps might be able to access 4636 without root. In there, if there's an option, select phone information, then lock the RAT to 4G only. Alternatively, if *#2263# or *#2683662# is available, in *#0011# select the other SIM if there is any, then in those other codes, band selection, GSM ALL (for the unused SIM), change SIM again with *#0011#, band selection, LTE ALL(for the used SIM). What's expected: If the SIM is not a USIM, the RAT will stay on 3G(UMTS/WCDMA). If the USIM is not authorized, no signal. With soft PLMN locking (manual operator search) the signal level is shown but it's unusable. If the signal is still not available, maybe the phone does not support that band/frequency or no LTE coverage? If rooted it's possible to add LTE only in those settings in feature.xml, if that file is not available others.xml is used. Or launch 4636, or RIL service mode with am broadcast.
Use this app (no root needed). Set to LTE ONLY. Works fine.

This is worth a try. It's 4636.
ADD THIS IN system\csc\other.xml
<CscFeature_Setting_CustNetworkSelMenu4>LTEONLY</CscFeature_Setting_CustNetworkSelMenu4>

its very easy. you just need to install this app https://play.google.com/store/apps/details?id=com.teknokia.mtkengineerapp&hl=en and choose LTE Switcher menu. for detail info please go to https://www.teknokia.com/2017/08/how-to-lock-4g-only-or-lte-only-on.html
*#2263#
so, i was going to look at the LTE bands enabled on my phone and when i dial *#2263# it says "RAT selection option is restricted"
never ran into this before, anyone have any ideas?
