Hi, I have a dual sim Moto G. I have a 3g sim and a 2g sim card.
I wish to use the 2g card for data and calls but the 3g sim for calls only.
Now I put the 3g sim in slot 1 and the 2g sim in slot 2. Now when i choose data mode for the 2g sim it changes the data network type to 3g without me choosing that option. And it changes my 3g sim to 2g network only.
I'v tried all sorts of ways but it still changes the sim network type on its own.
Any ideas on what i'm doing wrong?
Many thanks in advance, Ben.
P.S. yes I did search the forums first but I couldn't find any details about this issue.

In a dual sim mobile phone 3g network can be operated from one sim only so what you can do is activate 3g on the 3g sim and disable internet on it and then the only choice for 2g sim would be to stay on 2g and then you enable internet on it.
If it doesn't work try changing slots.
If I helped please hit thanks!

I have tried switching sim slots. What happens is when i select the enable data tick on the 2g sim the network type bar greys out and changes to 3g mode on its own. The only way i can change network mode is to de-select data mode and choose 2g again.
Cheers, Ben.
Hello,
Jellybean and below versions of Android have 2g/3g/4g only mode in the network settings only so this guide is basically for KitKat and above versions.
With KitKat and above versions the network settings are changed to "Preferred Network Type" and then 3 options (2 depending on the phone) are shown viz 4g (LTE),3g (Wcdma),2g (Gsm).
This means that when a user selects 4g in preferred network type and once he is in a low 4g coverage zone the phone keeps fluctuating between 4g and 3g/2g.This might result in an unpleasant internet experience.
So it is necessary to keep the phone in a single network mode to use a stable network connection -> This is true especially in countries like India where there is patchy 4g and 3g coverage.
DISCLAIMER:- The below mentioned steps for unrooted phones are completely safe and no harm may occur if followed correctly.
Rooting your phone may void the warranty and some hacks (such as xposed framework) may not be supported on your ROM (phone). Please read the respective threads for rooting,xposed framework,gravity box which are available on xda before installing them.
SINGLE SIM MOBILE :-
[A]- (unrooted) It's pretty easy. Just dial *#*#4636#*#* in your dailer and then select
'Phone Information' and then select LTE only ( or WCDMA ) in the drop down menu above "Turn off Radio".
- (unrooted) Use an app like 'Phone Testing' by diewland instead of dailing the code.
[C] - (rooted) If [A] and don't yield the desired result, then you must root your phone then install xposed framework and then install gravity box.
DUAL SIM MOBILE:-
SIM 1 :- For sim 1 follow the same steps [A] or or [C] which are mentioned above for single sim mobile.
SIM 2:- For sim 2, first disable SIM 1 in " Dual sim settings " and then follow steps [A] or or [C] .
Once your done then re-enable sim 1 . The sim 2 will continue to remain in whatever mode you selected.
PS 1 :- Although it can be argued that a simple sim swap will do (in dual sim phones) , this is faster than a sim swap.
PS 2 :- You have to perform these steps after every reboot. There is no way (not yet discovered) so that these settings aren't overridden after a reboot.
PS 3 :- Though there are numerous posts on xda, guides /videos on the internet which explain the exact same thing but I couldn't find any post/guide/video on the internet which explains these settings on a dual sim phone which doesn't require a sim swap.
Thank you.
this works on both single and dual sim and the settings will "stick" after reboot... requires root

Just switched from XSG to XSA. Although there is the SimManager for dual, it appears the support for dual sim is still different. I was able to get 4G+3G on XSG but not XSA. It was briefly possible when I first logged into my phone with XSA but was set to wrong priority. When I tried to switch, the function is gone. Anybody know how to force enable it?
Update: Figured out using 4G Switcher (called 4G LTE Switch in Playstore before install).
FYI who's also interested. Set SIM 2 to what ever you want and use the app to set SIM 1 to what you want. It can't modify SIM 2 settings. It appears I can't set both to 4G though someone can. But after setting in 4G Switcher, you can change data connecting back to SIM 1 and select keep current setting instead of changing to 4G preferred or it will automatically set SIM 2 to 2G only again.
Got the L29, so dual sim.
My first sim is for calling and sms, so I only need 2G but I can not set it to only 2G. Just the sim for mobile network (it's sim 2) can set to 2G, 2G/3G, 2G/3G/4G and only 4G.
The problem is 3G is really bad for sim 1 and this drain my battery for nothing, cuz I only need 2G for calling/sms.
I got a lot dual sim devices and this one is just strange in some things.
Regards
This is a problem for me, too
Dosen't work, I call already Huwei and they can not help me. Really bad :/
theres a setting in sim card management under mobile networks. it lets you pick which one gets data.
I can easily set 2G only for sim1 here, dont know what you did? Or your carrier doesnt support this, I mean if there is no 2G in your country, why could you change it to 2G?
Same problem on my mate 9 and my axon 7, seems to be an androidwide problem.

Naw, it works perfect with OnePlus 3, 3T, Mi5, Mi5s, Mi5s Plus and all other phones. Set Sim 2 to 2G/3G/4G and Sim 1 only on 2G. Here you can set Internet and this is it, the other sim go 2G/3G.

In "settings/more/mobile networks" I can set the preferred network mode for each sim card. Had this when I used it as dual SIM for my work: sim 1 data mode on 2g, sim 2 on 4g. Works perfectly, even on 2 completely different providers.

I don't believe. When mobile data is default set to sim 1, just to sim 1 can be selected preffered network mode.
In my case: sim 2 -default mobile data- can be set to 2g only/auto 2g3g...evrything. Sim 1 switched automatically to 2g/3g/lte auto-can not be set preffered network mode.
If i switch default mobile data to sim 1, preffered network mode can be modified in sim 1, but not for sim 2, and sim 2 switched auto to 2g/3g/lte auto.
I want like this:
1. sim1 default data-3g/4g/lte
2. sim 2---2g only. But this is not possible because just in this case, sim 2 jump into 2g/3g auto.

Nope... Just the sim which is for mobile network. If I change sim 1 to mobile network, I can set to only 2G but the other one will be 2G/3G

Ah I see what you mean! Have been playing with 3 different dual SIM phones last year so got it mixed up. What I did with my Huawei mate 9 when I used dual SIM was: sim 1 set to auto 4g 3g 2g and on sim 2 I overruled the automatic provider search and just picked the 2g network from my provider. It then still mentioned 2g 3g in dual SIM settings but it didn't connect to 3g because I selected a 2g only network.
Is this how you want it?
on my ZTE it's really funny. the setting is available but disabled lol
Fixed By using Tasker [No Root]
I got this issue fixed by using Tasker so probably there might be an ADB command to set the network mode
My fix:
Make a new task -> Press + button -> Mobile Network Type -> Choose required network mode
Note: Will need to enable USB debugging and use the command `adb tcpip 5555` for getting the permissions. Also this might need to be done after ever phone reboot
I am using huawei-y560-u02. it suports LTE but can not enable LTE.
none of changing system table and property>radio.lte ways working!
i enbled 3G in sim 1 slot.
