Is there any way to use ONLY 2G? - Xperia Z1 Q&A, Help & Troubleshooting

I want to use just 2G when I am at home, but the lowest option is "3G/2G".
Is there any way to use just 2G?
I found the method of *#*#4636#*#* and select gsm only
But i would like to see that option in the settings. Is there any way to do it?

Yes, go to settings->more (in the first section, just below xperia connectivity)->mobile networks and the check "Use only 2G networks"

I don't have that option. Lowest option is "3G (preffered)/2G". I am using French 157, maybe I should use another ftf :/

Did you check it? the "Use GSM Only" option has been in mobile networks settings since gingerbread days, and havent changed its place since then, at least its there in kk .108, i havent updated to .157...
It is actually not present in any popup list in settings, it is a completely separate "checkbox" in the mobile networks section...
It also has this text "saves battery", so maybe it is moved to power saving option? (HIGHLY UNLIKELY)

Nope, just like this. And there's no another checkbox there. Actually that is not a big deal, I can do it GSM-Only by dialpad.

Then maybe sony removed it in .157 or this might be due to the variation from region to region, heres the screeny of the checkbox i was telling you about.

The 2G / 3G / 4G / LTE / whatnotwhatnot options differs a little between the firmwares, depending on the region and branding itself. The nordic .157 FTF I am on is including a 2G only option, if someone here wants it..?

French Generic FTF does not include GSM Only option, even on Xperia Z too.

Rooting and Band Selection

I have exhausted every option known to me trying to get access to manual network band selection on the Captivate. The usual codes take me to the correct place, but I get an error message saying it's restricted. My question is will rooting the phone give me access to those menu options? I want the ability to lock the phone to GSM/EDGE or WCDMA at will. If anyone knows a solution to this, please let me know. To clarify: I am not looking to just turn off data and the *#*#info#*#* route doesn't work. Thanks.
Can anyone with a rooted Captivate confirm that you can or cannot access the menu to lock to GSM?

Hi,
No need to Root the phone at all. Just dial *#*#4636#*#* then click on "phone Information" scroll down to the drop down menu & click on it, click on "WCDMA" only & go back. done

What do you mean by "it does nothign"? I did it & working.
Setting 3G only or 2G only
I found out that if you go into the dialer and type in *#*#197328640#*#* that it will take you into a menu that will allow you to change it. From the main menu of the ServiceMode screen, select DEBUG SCREEN, then PHONE CONTROL at the bottom, then UE STATE CONTROL. From there select CHANGE RAT TO WCDMA to enable 3G only, and select CHANGE RAT TO GSM for 2G only.
THANK YOU!!!!!!!!!!!!!!!!
Doesn't survive a reboot but it's a start.

thanks for this.
but to take this a bit further, is there any way to automate this via a widget?
^Not from a widget in the market
They tend to wind up turning data off all together. Im sure it can be done though

Phone settings, wireless and network, network mode. I don't know if it's present in all roms though. There you can change the network band type

You have been mixed up....
Clear your mind,
*#????# - service menu is service menu,
root is root,
These are two different thing.
I'm not sure if band selection is disabled on all Captivate roms (it definitely is on some) but I have ran a number of I9000-based ones, all of which permitted band selection. Try dialing *#2263# to enter service mode and see if you're able to select the desired band. I'm using Perception 10.1, on which I can use this to modify the band settings and it is retained through a reboot.
I'm running perception 10 and there is an option in settings>wireless and network>mobile network>network mode> wcdma only or GSM only or auto.

Band selection in settings is only in I9000-based roms!!! It's non-available in Cappy-based roms!

Why is "Select Network" greyed out even on unlocked phone?

Settings -> More -> Mobile Network -> Select Networks option is greyed out! My carrier wants me to manually select Vodafone 3G instead of Vodafone to get 3G. How do I do this?
why do you care about the name?
the one thats grayed out is the band select.
google market> search > phone info > first menu> set your own band.

it doesnt connect to 3g because there's no 3g network in your area, chose the 2g one or vice versa
Not that simple. Here's what happened: http://forum.xda-developers.com/showthread.php?t=2034540
On phone information there are 2 ways to change things.
1. Set preferred network type. Options are:
WCDMA preferred,GMS only,WCDMA only,GSM auto (PRL),CDMA auto (PRL),CDMA only,EvDo only,GSM/CDMA auto (PRL),LTE/CDMA/EvDo,LTE/GSM/WCDMA,LTE/CDMA/EvDo/GSM/WCDMA(*),LTE only,LTE/WCDMA,Unknown
(*) default
2. Menu -> Select radio band. Options are:
USA Band,Cellular,PCS,2-GMHz IMT2000
DON'T CHANGE THIS ONE!
Yes, I agree (now that I've learned it the hard way!). But the "band select" that souljaboy posted above is for the second option that shouldn't be messed with!

I found the anser for this the other day. You first have to go into Network operators and unckeck Select automatically.

Go to phone settings and you under "SIM Management", default 3g 4g connection, change the SIM preference.

You can try with shortcut master app , you can access many hidden settings this way
Shortcut Master cannot provide access to most of the interesting codes since an Oreo update approximately a year ago...

If what this app does is what you're looking for, then I'm not sure what the problem is, because on my device I have a setting to lock the network to LTE/3G/2G (auto conenct); 3G/2G (auto connect); 3G only; and 2G only. I'm not sure what more you want.

I'm sorry i should've been more clear and precise. I was looking for the hidden activity called Hidden Network Settings that was present in Oreo. By using that i was able to lock my phone to specific Network Bands like B40 or B5 or multiple specific bands.
However in PIE that hidden activity is not present, i did go through all of them one by one.
Thanks for your help guys
Hi there , I've been searching for topics like this in the past three hours to share the way I did to make Hidden Network settings work on pie.
Here's what I have done. Well it may not work for you if you're not rooted but I believe that there's another simpler way than mine
First. I have downloaded hidden network settings.apk from apk mirror the last update which is on 31-03-2019
Second I have installed it using Lucky Patcher
Rebuild & Install > Navigate to the path where you downloaded Hidden Network settings > Install it as a system app ( integrate app to system ) > Reboot
Please let me know if it worked out for you

This would have been finally the Solution. But without root no chance to install as system app !! I am searching since Month to find a solution for my Note 9 and Pie.
I can't root because to many Apps and google Pay will cause troule with time.

I rooted my phone and installed the Hidden Network Settings app from OREO stock rom in PIE as system app
Just pushed the app in system apps directory with the right permissions
I am now able to lock network bands.
However it only works in rooted cases.
I wasnt able to do anything in stock unrooted rom
Is there a similar hidden menu that I can access to fix my GPS? It only works when I'm stationary, and VERY slow to update when I'm driving. The most annoying issue is that any APP like Google Maps is oriented 90 degrees in a different direction whenever I place it in "compass" mode (even when moving). I've done the figure-8 calibration numerous times whenever prompted, but it doesn't help.

Yes : download activity launcher
https://play.google.com/store/apps/details?id=de.szalkowski.activitylauncher
Then stretch for "hidden", and open the app that go to a phone icon named hidden something.
Then, in the hamburger menu choose the band selection mode, pick the bands you want to lock to, then activate it
go back to "Network mode" from the hamburger menu and pick "band selection mode".
That's all

Mate,thanks but i am on android 9 with note 9 rooted with the last updates and samsung removed that hidden network app with the last updates. I installed it manually as a system app yet it didn't work .I mean the root permissions in the file system not the typical permissions apps ask for camera,contacts etc when installing or launching. Also I heard something called "hns" removed with the updates and that's why it doesn't work if i even install that app manually.

Will this work for unrooted stock oreo to lock data from switching towers constantly?
I have a N9600 (TGY) device and I tried to manually select bands using instructions from this video:
youtube.com/watch?v=K-DN0q64lRw
I have the latest version of Android 10 available for this device.
I decided I'd rather NOT fiddle with these settings further and reverted everything... Now after a reboot, my device refuses to connect to the network. For example, I cannot make a phone call... Only after going to "Call Settings & Selecting "Automatic", I'm able to make phone calls again.
Any idea how to set everything back to default settings? I don't like the fact that the phone cannot make calls after a reboot as of now ... I'm using this device on AT&T, so what should the default selection be?
Thanks

This app lets you lock 5G/LTE/4G/3G/2G bands on most Samsung phones running the latest One UI updates: https://www.reddit.com/r/samsung/comments/g49ocr/app_samsung_band_selection_app/
After much headache with this issue, I found a method that works where the "Band Selection" menu doesn't work (this method is confirmed working on my Galaxy Note 8). Thanks @fasho:
https://forum.xda-developers.com/t/how-to-lock-lte-band.3681480/#post-74325453
TL;DR: Get org.vndnguyen.phoneinfo (from an apk mirror as it is no longer available on the play store), and then run ServiceMode as root. Follow the linked instructions further to disable unwanted LTE bands.

*#*#4636#*#* menu locked?

Hi all,
Living in an area scarcely covered with 4G, I've always used *#*#4636#*#* menu to set LTE only mode on my two previous phones.
But, apparently, on my P30 Pro this menu is locked by manufacturer. I can't access it and if launched from 3rd party apps, get an error message telling me this functionality is disabled.
Does anyone have any idea if it's possible to unlock this menu?
Thanks in advance

This did show all the settings, but when I tap to select, it selects the one that was set before selection, so doesn't really work
So, what I've found out, is the following - the value 11 (which corresponds to LTE only), doesn't display this option after restart, even when you put "11,9,6,2,1" instead of "9,6,2,1", and the value 12 (which corresponds to LTE/WCDMA) does appear after restart, but doesn't let you select it and falls back to GSM/WCDMA/LTE...
Only possible solution is to leave the field empty or put "-1" and select LTE only, which you can select, but even in this case you can't select LTE/WCDMA.
Thanks for the help!
