Did Mate8 support [email protected][email protected] ?

Did Mate8 support [email protected] + [email protected] ? That means we're always on internet if one of both with connection issue and immediately switch to another one.

No. Highest is 2g on the second sim. But you can switch up which sim slot gets the 4g without swapping the sim cards from their tray positions

No

That's normal for dual sim standby phones. To get simultaneous data and call you will have to make call on the data sim.

My data turns off while in a call

Using stock m9. Data 4g or other turns itself off when I start dialing and reconnects after I complete my call. Very frustrating when I need to search something while talking. Is there a setting I'm missing? Has anyone else noticed this?

Probably, you are missing VoLTE. Without this technology when phone using 4g and receiving call, it jumps to wcdma (3G) to get call, but drops mobile Internet in this moment.
To get everything working need:
- Mobile operator, who supports VoLTE
- Phone. Mate 9 supports VoLTE on paper, but not in all roms and not in all regions. For example, owner is living in USA, but has Mate 9 with chinese Rom -> no VoLTE.

You will have to enable VoLTE in order to get rid of the trouble.

I have the same issue also. I own the dual SIM variant and use one card for calling and the other one for mobile internet. Whenever I start a call the mobile data connection is stopping. I tried to enable VoLTE with no success.

In the latest C432 roms Huawei has removed the possibility to enable VOLTE for Vodafone Italy.
This possibility was present only in the first 2 update.

This is other case. If you are using one card for calling only, and second card for mobile internet only - you can't get call and mobile data together, cause Mate 9/Mate 9 Pro are DSDS phones (dual SIM dual standby)
To get what you want need have DSDA phone (dual SIM dual active). They are with two independent radio modules. Honor 8 for example.
Dsds phone has only one radio module but uses interchange method of work. On physical level it jumps from first sim to second then gets back to first. If you are in call with first sim, phone does not go to second -> no internet.

Dual SIM 4G+3G or only 4G+2G ?

I'm contemplating a purchase for a Mate 9 with dual SIM capability ( from Kogan Australia). It's advertised with dual SIM. For me, the secondary SIM would only add value if I can use it on 3G, while I keep the main SIM on 4G.
But in some documentation, the secondary SIM only supports 2G. Has anyone successfully used Mate 9 with 4G+3G SIM combination.

For sure....! I also think 4G+4G can work...

If the Australian version is the same as the European version it will support 2G, 3G and 4G on SIM 1 whilst SIM 2 will support 2G and 3G.

3G would be great on SIM 2. The problem I'm trying to solve is that our Australian telco ( Optus ) has severely degraded its own mobile network, to the point where we can't receive voice calls anywhere in our suburb. LTE used to work well, not any more. On the other hand, they improved somewhat on their 3G network. My wife is still in contract with cheap plan. So I could arrange a dual-SIM where SIM 1 is on 4G with another telco, while SIM 2 stays at 3G with the old telco. Things may improve for their network, or the company is going down, we shall see.

4G/3G is how it does it.
Both will support 4G but you'll need to put the switcher setting on your homescreen so you can switch quickly - you can't have both on 4G but both will support it. The other will be able to use 3G.
