Hello,
I have a BLA-L29 C432 now with the 9.0.0.206 update and since the update to EMUI 9 my sim don't work anymore and all the option in mobile network are greyed out below a list of what I already did but didn't fix the bug
- Restart the phone
- Changing the sim (my sim work on other phones and others sim don't work on my phone)
- Reset the network settings
- Reset the phones to factory settings
- Most of the dialers code when entered don't do anything it just clear the dialing code
The only thing that work is to downgrade to EMUI 8 but I want to be on EMUI 9
Does anyone have a fix for this ?

Hi !
I've searched for a thread and i didn't find anything relevant / a fix
My new mate 10 pro can't use 4G+ , the icon doesn't show ( only 4G it's show all the time ) and the download speed is not for 4g+
on my old samsung edge as soon as is open the connection is 4g+ so i'm sure the problem it's not the service provider, signal or the sim.
On mate 10 pro i've tried all the setting like :
- LTE high speed mode - > on and off many times, nothing changed.
- Volte calls on and off, nothing changed
- preferred network mode - > 4g/3g/2g
-Carrier -> automatic and manual , nothing changed.
- Factory reset - > nothing changed
- update software - > current version 9.0.0.243
It's something i can do ?
I stay in the biggest city in my country and i'm sure 4g+ is available . My sim card can do ( same sim card from s6 edge + ) , full signal .
Hi !
So i purchased a phone a few months back but since then i'm unable to use 4G on this phone. I've tried everything available through google's help and have turned to XDA as a last resort. I've tried
1. Hard reset (No luck)
2. Restoring default apn settings (No Luck)
3. Changing the connectivity settings via third party app (No Luck)
4. Changing sim cards.
5. Changing sim slots.
Edit:
6. Just tried to change the hw_networkmode_preference from setdb and couldn't find this setting there. created new setting for this and entered 9,6,2,1,11. Now i get 4G only option but as soon as i select 4G the phone shows No service.
All of the above tried multiple times without any luck to get it working. Its like its just stuck o 3G and wont use 4G although the option is there. The sim card's $g connection works fine in my other phone. but not this one. If anyone has any idea how to get it working please respond ASAP as i need this phone working for my sister and cannot afford another.
My Phone Info :
1. Name: Huawei Y7 2018
2. Model: LDN - L21
3. EMUI Version: 8.0.0
4. Android Version: 8.0.0

It's NOT you who decides what band network to get used, it's alone carriers decision.

I get that. but the same carrier allows 4G to be used on other phones. why not this phone ? its got to be a software bug or maybe they forgot to install 4G hardware
Any other hunches ?
Hi,
I have a huawei p20 lite dual sim however when I put my mtn sim card into the device it doesnt register on the mtn network it says no service, However if I insert both my work sim and private sim the phone then recognizes my private sim BUT only on edge the mtn-sa comes up but under that it says no service.
If I only put my private sim in then the phones straight away says no service and no matter what I do it still says no service.
I have resetted the network settings,
I have booted the phone in safe mode
I have set the phone back to factory default
I have formatted the partition
But with all this being done I still cant get to work the phone shows my number under dual sim settings though.
I'm really confused and dont know what els to do or try.
I also should add that my phones running EMIU 9.1

Hey, thanks for stopping by
I have a mi pad 4 8" tablet running android 12 (lineage), but I'm looking to install a Vodafone sim card but it would appears to read the sim card but fails to connect to the network... I checked the sim card on a stock mi pad (and same thing happens) I own 3 of these...
I have noticed if I press "manually select network" it only lists EE & virgin as options ... Does this mean the device is network locked ???? - this also is the same in the stock tablet (thinking it was a rom issue)
Someone mentioned a damaged "modem partition" but this doesn't explain why It doesn't also work on the untouched/locked factory tablet.
Any help or advice welcome
I have been Network Signal Guru on several different mobile with no Issue. However, on Realme GT 2 Pro with A12 V21 RU ROM, when I pressed "Clear All forcings" both SIMs signal completely down. So I tried restarting. Even after restart, No network came on boot. However, after approx 10 minutes, Network came on both SIMs.
So, basically, I have to wait for 10 minutes for network to show on every reboot.
I have tried clearing Network settings from Settings, and, flashing same Full OTA through local Update , and , Full data wipe through recovery, and updating to A13 C12 Full OTA. Still no benefit. Network appear after 10 minutes on reboot . App developer is saying that OPPO devices are different, and could not give any solution.
Please provide any solution.
