I got mine two days ago, but I am using SignalCheck Pro, it tells me I am using AWS band 4, but MetroPCS is also using T-Mobile Band 2, are there any app which allow me to manually select that band? Also how can I detect Band 12 when it is made available to us by T-Mo/google?
Here you go.
1. In the phone dialer dial: *#*#4636#*#*
2. Choose "Phone Information"
3. Press the ellipses in the upper right (three dots)
4. Choose "Select radio band"
It appears they did get VOLTE working but band 12 it's not select-able yet. I assume we'll need another update for that.

Type dialer *#197328640# and go to UMTS>DEBUG SCREEN>PHONE CONTROL>NETWORK CONTROL>BAND SELECTION>GSM BAND OR WCDMA BAND
important...
1. hit your conty carier network band. others not working eg, sri lanka gsm band is 900/1800. wcdma 2000
2, dont hit any other options. if hit you may broke your rom.
3. befor you going to flash another rom first hit the band to automatic
UMTS>DEBUG SCREEN>PHONE CONTROL>NETWORK CONTROL>BAND SELECTION>automatic
if you help this advice just hit the thanks button.
How to get into that menu.. What's the code?

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
Hi all,
Just wanted to know if it is possible to enable LTE band 3 (1800 Mhz) on an SGH-M919. Is it hardware restricted or can be enabled by flashing a modem?
Thanks in advance.

Hi.
I am interested in this also. When I select band 3. It does not really get selected. When I go back in the menu it keeps the (*) marking the selection on Automatic. While if I select, for example, band 2,4,5 the star moves to them and I get disconnected from the network.
Is there some setting somewhere that I can enable that in?

It will not show the (*) when you choose band 3. Just choose LTE/GSM then go back and choose band 3.

That didn't work for me. (*) is not shown for band 3. but I was able to select band 4 or all bands, and obviously there is no network.

It does not get selected. I think it might be disabled somewhere.
I wonder if it could be enabled through editing the QCN file.
One of the good things about the gs6 is the ability to for b12 and even better ability to choose preferred band in automatic mode.
Does the m9 have some sort of ability like that?
You are talking about the WIFI channel 12 (which is illegal to put your WIFI on in the US)?
Actually I think he is talking about forcing a specific LTE band... (in this case LTE Band 12 which I think is for T-Mobile). Specifically accessing the LTE Band service menu.
For any Samsung device you would enter *#2263# and the "LTE Band" service menu would open up and you can force a specific band. IF this is what he is talking about, it’s actually a great feature because you can "lock in" LTE to a specific band, I use to do this all the time in the Philippines so I wouldn't get kicked off the LTE band. You can also see what LTE bands the phone supports.
When I had the M9, I looked everywhere and tried to find the code to access the LTE menu but I was unsuccessful. Maybe someone here has the code to access the LTE service Band menu. There were some generic codes that work for Google in general BUT none of them worked on the M9.
Try *#*#4636#*#*

*#2263# doesn't work for me
But yes LTE band 12
##DATA# on Sprint lets you do something like this, but I believe that code is Sprint-specific.
anyone own a Three branded G4? i assume your still on 5.1
can you let me know the software version of your handset?
i just got a used one, im on three network and wanted to make sure its on latest, im in V10h-234-20
Build: LMY47D
is is software a three branded one?
Yes it is
thanks mate
do you know how i can test band 20 (800Mhz) ? i believe it will only be selected if no 1800Mhz 4G/3G is available
i want to test VoLTE indoor

Dialler > 277634#*# opens the hidden menu
Field Test > Modem Settings > LTE BAND SELECTION > Tap Band 20.
If you're in the range of the 800 MHz the phone switch to it and will ONLY use it (until restart) or until you toggle WCDMA / LTE in the normal settings.
If you're getting No signal, go to manual network selection (do not change to WCDMA/LTE, leave it on LTE) and search for networks. If you don't see 3 RAT 4G, well, you don't have 800 Mhz.

No, I can see it was released 10 days ago but no link to kdz yet. Not sure if worth updating or waiting for MM

i have a modified G4 (using your guide including the very last update changes), the OTA function can't find an update....likely MM not too far away.

OTA usually doesn't work on modified / rooted ROMS, so it's expected behaviour
ps. just checking. I can select band 20 and 4g works. if i select band 3 (1800) it keeps finding signal and unable to lock despite there being 1800 signal. does selecting band 3 work for you? is there a way of setting 4g only - so it works 800+1800 only ? (i know no volte on 1800)

hi, i have seen your previous guide on how to flash a G4 to work with 3's VoLTE
Is this still the case if i want to use VoLTE on a none 3 purchased handset ? guessing simply flashing the 3 stock ROM is not going to work?
If you try to change bands in the service menu (e.g. from Band 4 to band 2) and you have LTE but phone calls don't work at all (just says call ended instantly), just go to "network mode" and select automatic, which will get voice working again on your new band.
Turning the sim card off and back on won't fix that--that will just make the band reset to default (with voice working) which isn't want you wanted if you were switching bands.
This can be useful on low tier providers if one band is lagging horribly and another band is more reliable.
I just recently discovered the service menu, does this actually enable bands that normally aren't active? I see Band 71 here which I thought was only available on the TMobile US variant, yet here I am with the ULM model and it shows it in the menu. I'd like to enable it in case I'm ever in an area that supports it, but I'm not sure what this menu actually does?
