920CD Dual sim - is it active?

Could you explain how dual sim works?
Does it work at the same time or have to switch between sim1 or sim 2?
For example
Use SIM1 one for internet browsing – somebody will call me on SIM1 or SIM2. Will phone ringing on both? Or for SIM2 calls have to switch to SIM2?

interested to know as well.

You have to turn call forwarding active.
Under sim card manager, lase section general you need to select dual sim always on. with this if you are speaking on sim one and you get a call on sim two it will come on sim one as it will get forwarded. so you wont miss calls from either sim even if you care on a call.
For internet both card slots have 4g but only one is active 4g and second will be 2g. you can select whichever you want.
I have N9208 and assume it is the same for dula sim Note phones.

So there is no way to get calls to both SIMs without calls forwarding?

Not 100% sure but don't think so mate.

You'll get calls to both sims when idle, unless you're already talking on one. That's when you need call forwarding, so you won't miss second call.
SM-N920?

It is sounds better
What about situation when use internet data? For example downloading file using SIM1? Can I still get calls to SIM2?

Yes. While downloading if you're setup to use data on sim 1, you'll get call on sim 2. When you pick up that call download will stop I think. Not 100 percent sure cause different phones have different arrangements... If your call comes on sim 1 the data will continue to download. Vice versa.

Hi. I have a galaxy note 5 dual sim (n9208) and when I'm on a call on sim 1 (configured as 2G), automatically i lose the internet connection in the sim 2 (configured as 3g/LTE, but my network is just 3G) and I stay without internet connection all the time while I'm on the call.
I have set the sim 1 only for calls (2g) and the sim 2 only for the internet (3 / LTE but my network is only 3g).
It is very inconvenient not to have internet connection while you are talking on the phone you can not receive a whatsapp or browse.
There is a way to solve this problem?
Thank you.

4G connectivity while on call

I was using single SIM so far, while receiving a call, 4G would change to 3G but will still stay connected, so Truecaller would work.
Currently, I'm using a second SIM for 4G connectivity, and SIM 1 only far calls, but the moment I receive a call, SIM 2 looses data connectivity and Truecaller can't fetch any details about the number.
Anyone knows any workaround for that ?

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.

Format data and refresh official firmware from beginning. Make a backup of important files first.
