Dual Sim Issue

So I have my Verizon sim in tray 1 & my T-Mobile sim in tray 2. What I am trying to do is have the data push through the T-Mobile sim but still maintain calls and text coming in from Verizon sim. When I set Dial to sim 1 & Internet to sim 2 in the options it just shuts down the Verizon sim completely. What am I missing? Is what am trying to do not possible?

20 views and nada, come on someone has to have some input they can provide me lol

So I finally got the phone to keep both sims registered to their networks and my calls and sms work with it set to my Verizon sim but I can't get the data to push through on the T-Mobile sim!!!!! AHHHHHH

I think the Mi MIx only has 1 4G radio? So that if both SIM cards require 4G connection, only 1 can be connected at one time

I understand, this is exactly why I wanted this phone too! Where did you buy yours and how long till you received it?

No voice calls.

Can you tell me what you did? I have data and sms going through fine but no calls.
Thank you.

Has any one resolved this issue?
I recently got a VZW SIM card, and everything works when it's the only SIM in the Mi MIX...but if I also put in my Project Fi SIM...I cannot send SMS via my Project Fi SIM--which carriers my main number...even though MMS also works on my Verizon SIM card......

Dual Sim Data Questions

Hi,
Got the note 9 since friday. working great. but i noticed that when i call on sim2, i can use mobile data of sim 1.
Default mobile data is from sim1. and phone calls are set to ask every time.
now my sim2 is my work number. during the working hours i call alot with this number.
my sim 1 is my private sub from t-mobile. and i mainly use the data plan of it. since i dont wanna use the internet that my boss pay's for for my personal use.
Now since i got this setup. what happends is. some one texts me a foto through whatsapp. and then calls me to sim2 before i can look / dowload the picture. then when i pickup the phone they ask me did u see the picture i sent you. i then open whatsapp. but i get the msg no network.
what i noticed is that when i call on sim1 i still have LTE data. (cause sim1 provides the data)
so it cant use data from sim 1 and voice from sim2 at the same time?
also is there a way to set certain apps to use data of a specific sim card?
lets say i open my 2nd whatsapp that it loads the images sent there from my sim2 network
but when i open my 1st whatsapp (2nd app cloning) it uses data from sim1?
or any other apps for exmp chrome and samsung internet?
is there any tweak that automates the switch data to sim2 as soon as i make a call with sim2?
now i can just click on the sim settings menu and change the default data to sim2 to receive data during the call. but when im driving in my car this are alot of buttons to press and i rather not.

i don't own N9 yet. read about dual sim technology varieties on the net, theoretically N9 should be able to get dual VOLTE feature on both SIMs (assuming it supported by carrier(s), and phone shows VOLTE icon on both SIMs). in the event you are making call on SIM 1 & trying to get data on SIM 2 or vice versa, this requires dual sims dual volte (DSDV) feature kicks in and liberates you to choose which SIM to get data from.
might really want to consult with your carrier(s) if both SIM support VOLTE.

Are you able to get VoLTE and WiFi calling to work on the international dual sim F variant of Note-9 on US T-mobile network?

Dual Sim issues, can't make calls on sim1 when sim2 is inserted

Hi,
I rebranded my VTR-L09 to L29 two years ago.
Since then I use the dual SIM functionality nearly every day at work.
SIM1 is my private card, SIM2 is my work card.
Both are in the same network (Vodafone DE) but different providers (SIM1 is 1und1 and SIM2 is Vodafone).
Since some days I'm not able to make calls with SIM1 when SIM2 is inserted.
When I try to make a call while SIM2 is active, the phone app switches automatically to SIM2 without asking.
When I disable SIM2 in Dual SIM settings, I get the message "Mobile network not available" (translated) when I try to make a call.
When SIM2 is removed I can make calls without any issues.
Internet (HSDPA+ and lower, LTE is not available in my contract) and receiving calls is still possible and without any issues even SIM2 is active.
In dual SIM settings the standard SIM for calls setting is disabled, but even if I set it to SIM1 the calls will go over SIM2.
I already called my provider and I will get a new sim card but I doubt that this is the issue.
Does anyone knows this and is there a fix for this?
I'm on C432 B376 by the way, and there's no update available for me, yet.
My phone is also rooted.
A factory reset would be very annoying since it takes extremely long time to back everything up.
Greetings,
Jannomag

I also have rebranded my VTR-L09 into VTR-L29, but I have no dual SIM issues. Build number 376 (C432). What happens if you swap the SIMs?

The same issue, but inverted. The phone switches to my companies sim card automatically.
Is it possible that the network provider block this standby dual sim thingy?
I received my new sim card but it still doesn't work.
A few days ago I installed Google's phone apk as a second phone app for my second sim, because I wanted to seperate my private and companies contact lists. This didn't worked as I expected and I completely removed it and deleted cache and dalvik via TWRP.
Maybe the issue was produced by this, but how do I remove it?

It sounds like a plausible explanation. If that is the case, I am afraid the only thing that will help is a factory reset, unless you figure out what changes were made by the google phone app.

I did a factory reset...took about 5 hours to get everything like it was before.
Even with TB some apps don't work good (WhatsApp for example, needed to reinstall it...but somehow the backup from yesterday was gone, so I got a throwback to last week).
Now I can make calls again as usual. Strange behavior...

It looks that google dialer apk messed something in your phone. good to hear,that all is ok now.
I am also rebranded VTR-L09 to VTR-L29 year ago. I am on C432 B379.
both SIMs are on Vodafone network and everything works as it should (SIM1 - private+data enabled, SIM2 - work+data disabled).
I am on stock firmware, no root, stock dialer. @Jannomag : 5 hours?Really? I made factory reset two months ago (backup trough huawei backup) and it was matte rof 1 hour. Of course i have to sign in to FB,Whatsap,instagram...

Dual sim Data confirmation if possible

I saw something a bit odd here. It says here on specs that secondary sim only supports voice but from what I know is that both SIM cards support data. Is there something wrong here? Do both sim slots not support data? To the best of my knowledge with this phone you can have two SIM cards and use data on both of them allowing you to download two WeChat apps and have two numbers for each WeChat account on one smartphone. Is this not the case now?? See link from HK below and look at the bottom of the specs page for supported bands on SIM card tray.

Hi
I don't have a second SIM handy but looking at the settings you set the phone with a default SIM for calling and a default for data. Makes sense you would have to do this. So outbound calls and default use of data is pushed through either SIM. Don't know if that helps....

Found a SIM and popped this in. I now have another option enabled which says switch data connection between calls. So the option moves the data to SIM 2 when taking a 4g call on SIM 1....

Dual SIM options

Single SIM only in Canada VOG-L04 model.

no internet connection during phone call

Hi,
I use dual sim and one is for phone calls and one for internet connection. When I make a phone call, there is no connection to the internet. Navigation with google maps says that it is offline and no messages or mails are received. When the call ends. The connection is working again. During the call the Mi8 shows 4G for both sim cards.
Is this a configuraton problem?

Hi!
There is not active-active SIM card slots, it means that if you do a phone call with SIM1, SIM2 will be off-line during the call.

Try this, go to settings and in the search bar on top write: unrestricted data
Open the menu, more, show system and find Phone... Enable it and try it again see if this solve your problem.

Try this: set your region to Hong Kong, then reboot your phone. Once it's on, go to the Sim Cards & Mobile Networks option and enable VoLTE on both Sim 1 and Sim 2. Then give it another go.

Hi, thank you for your replies. It works now with VoLTE, but only if the connection is set to SIM1. SIM2 is off during calls.
