know how many minutes I had I dialed the USSD code it displayed 'Connection problem or invalid MMI code' I signed in to my provider homepage to see if something was wrong and it said that my account was active? I'm on carbon ROM and my phone is rooted. I even took out my sim card and put in a different phone that phone sim card on my phone and it worked, but my sim card didn't work on the other phone when I dialed the USSD code it said 'Unable to process Request'? I have T-Mobile prepaid service. What should I do?
I am S-off, rooted, unlocked bootloader...But just went through some resets & other headaches yesterday trying to install the last OTA... Whatever I did, the phone seems to be having a few problems.
First, when I boot up, as expected, it seems to connect to the network pretty quickly. Then it finds my Wi-Fi and authenticates with it.
Then it switches to Wi-Fi calling... But it also then says there is "no SIM card". Really weird.
I downloaded a generic SIM card info app from the play store and looked at the information on my SIM card. From what it looks like, two fields are blank: (i) the SIM operator field, and (ii) the network operator field.
I am have not changed my CID so that's not a factor.
Can someone else here (who is on stock but rooted) check their SIM card to see if there are any values in these two fields?
Thanks!
Hello
I have LG SPRINT LS980 i have two problems, i wish that someone could give me solution :
1- i was on KK 4.4.2 (ZVD) and after that i tried ( ZVC) and now i'm on ZVG LL but with all these Versions i never had sim card contacts list, i can't even import from sim card, it's just like it's not inserted, i unlocked sim card and i followed a lot of tutiorials about that, it reads sim card, and i can call and everything, but still can't see the contacts list
2- there is no APN settings on the phone, i can't change Access point name settings, i can't even See them, i need to see and modify the settings without using a 3rd party app
plz any solution ?
Does anyone here noticed that when you enter *#*#4636*#*# you wont get sim card 2 information.
Also, contacts app can not read my sim contacts for both sim1 and sim2. Importing the contacts from my sim showed that there is no saved contacts in it, so i have to insert my sim to another phone to check that there is indeed contacts saved on my sim. Can anyone help me with this issue. Running on the latest build for le 2. :good:

Hi all, I just got it for 3 weeks now. So far I got some finding :
1. Mobile banking never send me sms verification, if I install both Sim card and set them on. It work if I only install one single Sim card in Sim card slot 1.
2. This make me look for double Sim setting, but I only find call default setting option. I don't find sms default setting or data default setting.
3. If I make a call, it always asking me which Sim card should I use. But I have set in the call default setting option for sim card 1.
4. In gaming experience (note: I use swipe as iPhone for navigation), jetpack joyride and zombie smasher cannot exit. Mortal combat (full screen mode) the screen turn all black but I still hear the sound and the app running.
Is there someone can help me, solve this.
51 persons read, but it seem no one have this experience.
If you have the Chinese AL00 version the posted [ROM][AL00] Mate 20 X GlobAL00ized beta [Debloated][Mostly Deodexed] rom will allow you to use Google Pay when you also have root. You'd have to unlock the bootloader, install TWRP (also has been posted), format phone (including internal storage), install rom and install Magisk for root. You need to hide Google Pay from Magisk (also may have to hide Google Services Framework) and mobile payment will work. As for selecting a sim to always make calls and not always ask, I have Settings->Wireless & networks->Dual SIM settings->Default calling SIM set to SIM 1 and my calls use that sim without asking. Then there's Settings->Wireless & networks->Dual SIM settings->Default mobile data with radio buttons to choose between SIM 1 & SIM 2 for mobile data. Hope this helps.
To get gestures working fully ie. Exiting out during full screen, enable the on screen navigation ball that lets you long press to toggle recent apps or short press + left or right to back out of an app. This works great for apps not fully compatible with full screen + gesture mode.

Thanks for your response, FYI mine is EVR-L29.
yes I did find the location of "Settings->Wireless & networks->Dual SIM settings->Default calling SIM set to SIM 1 and Settings->Wireless & networks->Dual SIM settings->Default mobile data with radio buttons to choose between SIM 1 & SIM 2 for mobile data" .
But still even I set the default calling is to Sim 1, when I make a call it always ask (chose to use Sim 1 or 2).
The default mobile data is working well.
For comparison in my cat s61 (android 6.0.1), I can find setting for preferred Sim. Options for cellular data, calls, and sms messages (this option I can't find in mate 20x & vital for m banking setting) .
And m banking is working well with this cat s61 even I install 2 Sim cards.
Have you tried factory reset? In some earlier threads (soon after the release of this phone) I vaugely remember ppl stating the first thing to do is a factory reset to fix some issues they were having. And that would be a good time to unlock the bootloader in order to gain root since a factory reset is required to unlock tge bootloader. Just a suggestion if you haven't done it already.

You don't have to root, it just allows for more control over your phone and only suggested to do it if you wanted cause a factory reset is required when unlocking the bootloader. At the very least I would performe the factory reset to see if that solves your issue and to get any available updates via Software update app.
Latest report, why mate 20x always asking which Sim to make a call even I set sim1 or 2 for calling? This is becos the third party app I installed error, I don't know why. But after I uninstall it. Mate 20x call a number never asking again.
But still my m banking only working if I plug only one Sim card (registered one) into sim card #1 tray.
SMS verification still can't be received if both sim card plugged in.
Is there anyone can help me solved this??
same problem with me , because i can only use mobile bangking if i choose default mobile data with the sim card that i registered from the bank , so i have to often to switch default mobile data everytime i want to use mobile banking , any suggestion so i can choose default sim card for message because it's seems that the phone are use default mobile data setting for default sim card for sending message.

you can use 2 sim card but you have to choose default mobile data with the sim card that you registered with m bangking , because the sms verification are sending message based on the sim card that you choose for the default mobile data.
