How to lock sim-1 to 2g and sim-2 to 3g. - Asus ZenFone Max Pro M1 Questions & Answers

Due to network switching between 2g/3g i am experiencing inconsistent internet speed in my sim 2. Is there any way to lock my sim-2 to just 3g. My old phone used to have very useful 'WCDMA only' aka '3g only' feature. Also is there a way to lock my sim-1 to just 2g always. (That connection is just for incoming calls)

You can lock sim1 networks by Dialing *#*#4636#*#* from dialer app, select Phone information then select network mode you want and turn off the mobile radio and on again.
(Warning: Do not change/update any other settings like sms center etc)

Thanks, Is there any danger using this method? Also does this method allow to use two different- (2g in one sim and 3g in second sim at same time'? or can select only one kind in both sim?

No problems using this method IMO. But don't try to change any other setting.
Also network selection is only available on SIM1. Some manufacturer do have two options for both SIMs but not in our device.

Carrier switching - Note 3 LTE

Hi
since i flashed my n9005 with 4.4.2 i have problem with carrier switching,
i use carrier that allows to connect with network by two ways:
by mother carrier - let say nr 1
or by two other carrier with domestic roaming - networks 2 and 3.
when i use my network 1 - i can connect with LTE speed, while in roaming only speed H is allowed.
And my problem is when i manually connect with network 1 my phone keeps switching to 2 or 3 after loosing signal even for few seconds - in elevator or staircase.
I wanted to lock it on my network by i can't.
Didn't have that problem with Note2 LTE...
is there any way to lock on single network, i don't have option to disable roaming, there is only option for data roaming.
Have you tried just going to settings --. connections --> more networks --> Mobile Networks -> Network Operators --> selecting the #1 network? If you select one here, the phone should turn off Auto switching and it can't change to another network unless you select one manually via this method. Or at least, mine remains on 'no service' untill I select another when crossing the border.

Why my network keeps changing from 3g to 2g??

Why can't i keep a 3g only network ? i have this option in my Xperia z ... why can't i do that in my Moto .. its really frustrating ... i have 3g data pack and moments later i realize my network is on 2g n its eating my balance rather then my net pack .... frustrated :/
Doesn't this work?
*#*#4636#*#*
Select WCDMA only.
If you cannot reach it using the dialer, use an app to do it. e.g. shortcut master lite or something.
If it still doesn't work then make sure you sim is in slot 1.

Try dialling *#*#4636#*#* and select the first entry (Telephone information). You can set your preferred network type there. On my phone there are a lot of options to choose from, including LTE only, WCDMA only, etc.

Switching betwen 2g/3g/4g

Hello
I'm with Leeco Le Pro 3 AI with stock rom 5.9.026s
I notice that my battery drops almost 25 % per 10 hours . Battery used when phone is idle - 30%. The reason for this as I think is that the signal in my place is not so stable so the phone constantly changes between 2g/3g and on some place in 4g.
When I go to settings / Dual Sim $ mobile networks / Network mode i see that it is on auto - ( 2g/3g/4g ( auto) ). The problem is that I can't set it expressly on 2g. There is no option on this settings to choose the type of signal.
If I click on Sim Card slot 1 ( I have only 1 sim card on my slots ) and next click on Netwrok Carrier there is 2 options - auto select and Search for Network. When i go for Search for network i found my local network signals and it shows 2g 3g 4g ... I choose 2g but this do nothing. The phone again is in auto mode ( 2g/3g/4g ( auto) )
So does anybody has any idea of how to expressly set the phone to use exact network carrier ( in my case 2g ) not to be auto?
I believe you can force certain bands by typing this into the LeEco dialer: *#*#4636#*#* and choosing "phone information". Select "GSM only". Use this with caution. Your SIM might stop working because your provider might not support 2G only.
I thought there was an option to choose 2g 3 or 4g separate ???

IDK. Just chose GSM only if you want 2G only. Or better yet, pop your SIM into the second SIM slot and you'll only get 2G. Much safer.

EDIT: Whoops, confused you for OP. That's what I get for not reading usernames.
I don't see an option for only 4G - LTE ?
It is only 2g/3g/4g auto.

AFAIK, it's supposed to give you a bunch of options: https://www.learn2crack.com/2016/01/force-2g-3g-lte-only-mode-in-android.html
Otherwise just choose 2G or LTE as your preferred network type in Settings.
Maybe try an app like this: https://play.google.com/store/apps/details?id=www.extremedroid.com.a4gltetoolkit&hl=en
sk8223 - my settings doesn't allow me to choose between 2g /3g or LTE it is locked on auto! There is no option on my model to choose network type.
Sweeden - I thought so that there is such option just as your screenshot but for Leeco Le Ai there is no such one.
Also there is no option to switch off sim card when you are with only 1 sim card. Actually there is an option - but it doesn't work.
So I will try some kind of app to switch between network type
Leeco Le pro 3 AI has really awful ROM- good hardware but the ROM is the worst I ever used
I badly need a custom rom for this model

Just to let you know. After restart of the phone you must do it again.

Have you tried some kind of app that let you choose only 4G and that really works even after the restart of the phone ?

No I did not.. but as I see on this thread the link to the app it change the settings on the same place as the call combination *#*#4636#*#* ... So i suppose every app do the same things. But to use this code is not so bad ... from there you can choose, 4g it works!
The bad thing is that my issue with battery drain still exist so i will continue to investigate the problem. Phone in idle consume too much electricity - some **** app sucks my battery energy! Every day I have issue with this phone - it is so time consumption .. bug after bug

This works just for a moment for me! Any other tricks that can force 4G LTE even if there are no 4G LTE signal? Thanks
Edit:
Use this instead to force 4G LTE without the ROM changing it back to auto.

Select "Network Selecting" then change to LTE only. Don't mess with the others, I heard it might destroy your device.

can't change network mode!

hello!
I am trying to set my network mode to WCDMA because I want to use data and receive calls on the same time since my carrier hasn't enabled VoLTE (that's another story...) but I can't!
The option is there, settings, more, Mobile networks, network mode, i make the change to "GSM/WDSMA auto" but it won't stick! If I go back and come again to this menu, the option is reverted back to "GSM/WDSMA/LTE auto"!
There is no luck either with the LG hidden menu, *#546368#*870# , it says "Connection problem or invalid MMI code".
Could this has to do with my modded kernel?
Any other ideas?
Here is my setup right now:
LG G6 H870
Android 7 Nougat V11i-EUR-XX
Melina kernel 3.18.62-melina-rel7_2017.12.31_uber-6.x_STOCK_zefie
Thank you in advance for your help!
That is a GSM phone. You cannot simply switch to CDMA. Different hardware.

what?
If i know that correct, WCDMA = 3g, right?
I want my device to be locked to 3g only, not 4g, because when I receive a call, it drops from 4g to 3g and I lose my internet connection, which is really frustrating if you are in the middle of a video call!
