I have a Huawei G730-U00 that support dual sim. But only Sim 1 supports 3G network. Is there any help to switch 3G network on Sim2 without power off and change Sim Card? I want to change 3G network on Sim2 if Sim 1 is deactivated while using 3G on Sim2. Please help. If it needs rooted devices, or any force enabler, it is OK. Thanks
I got it now, to change 3G network without power off and changing SIM cards.
Thanks, everybody

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
Hey I recently purchased Pixel XL from store.google.com and had it shipped to California and took it to Shanghai, China. After inserting the china telecom sim card, i found that I can only make/receive phone calls but cannot connect to LTE network.
It is clear that the hardware does support the china telecome LTE network. I even find a small tutorial of switching to a mode where I can use LTE network but cannot make phone calls.
Dial *#*#4636#*#*
on the upper right cornor , choose United States
in the middle of the screen choose CDMA AUTO (PRL)
turn on Airplane mode and then off
Then I can find LTE signals.
But the phone cannot make phone calls under this mode.
I'm not sure if I can switch it back to make phone calls mode. And is it possible to solve this problem and make it able to receive phone calls and have LTE network at the same time? Tremendous thanks!! If I can provide any information, please guide me to find the information and I will happily provide!.
Have you tried LATE/CDMA/UMTS auto (PRL) mode?
I could imagine that this let's you use both, China mobile LATE (which obviously needs the CDMA mode) as well as UMTS as fallback for calls.

Currently a file(carrier_policy.xml in the EFS partition of Pixel 2 series and probably Pixel 2016s) lacks proper configuration for China Telecom with its LTE network using SRLTE (which is a common practise of establishing the CDMA and LTE network at the same time).
Thus the team can and should fix it by:
Adding the following 2 strings(in red) to the carrier_policy.xml in the EFS partition as follows:
......
<!-- List of the MCCs in which SRLTE is allowed -->
<mcc_list name="sxlte_mccs"> 455 460 </mcc_list>
<!-- These are the serving system PLMNs for which SRLTE will be allowed
-->
<!-- NOTE: Proper functioning of the SRLTE policy requires that there
be an PLMN list named "sxlte_plmns". Do NOT rename this list.
-->
<plmn_list name = "sxlte_plmns">
455-02 455-07 460-03 460-11
</plmn_list>
......

Good evening I turn to you because I have a problem with my slot sim 2 I do not have a 4G. When I activate it I have no network. Roaming and any other settings sound activated. At least I hope so.
Although the phone tells me that the network is available, I can not call or receive calls (same for SMS). On the other hand, a priori, no problem to access the internet via 3G. When I try to call I have the following message: Mobile network not available
Help me
Have you tried any other SIM?
You need to go into your mobile network setting and Dual Sim setting to make sure Sim 2 is active.
Now if you want Sim 2 to use 4G you will have to select this in the Dual Sim setting. By default Sim 1 is the default mobile settings.
At any one time 2 sim are in the device only one will use 4G or 3G the other will use 2G.
here are the tests I made with reboot
