So, the OP7Pro has duel 4G capability. Would it be possible to tether from sim 2,whilst using data on the phone for sim 1. If 4g is activated for both aims, this would be great as I wouldn't slow down my data when Tethering lots from my laptop. Happy to throw some money at it if a dev can help with that.
As far as I understood, the Dual 4G means, the phone uses 4G on both sim (allowing VoLTE for example). But that switch did not lead the phone to use data on both sim simultanously... data uses always the selected sim for data.

Ok, that makes sense (and does work) - but to counter that, my network's VoLTE band allows you to use data on that band, as they also use it for extending indoor coverage, and so i can use data on the phone. Think it's still possible?

From what I've read, you can pop a Verizon 4G sim into pretty much any unlocked LTE capable device and have it work.
Now I'm guessing this is going to be a no, but...
I got an Airtel 3G Data card (specifically the Huawei E1731) when I went to India and unlocked it, if I remember correctly it kept swapping from CDMA and GSM signals. Now if I pop the Nano SIM I got with my iPhone 5 into this data card, (I'll try to make my self a Nano SIM to SIM adapter) is there any chance of it working?
I've also heard if things like the 4G sim being deactivated when you swap to a 3G device. But wouldn't putting it in a 3G device be the same as using the iPhone 5 with LTE turned off?
And is there any chance of Verizon messing with my data plan if I put the sim in the data card and start using it with my laptop?
I just saw a a video of someone putting a nano sim in an iPhone 4s and it working so I think this should at least work on the data card, still worried about the Verizon side of this.
Also I just remembered something about different frequencies, would the fact that the data card is from India affect my ability to use it?
Actually, I'm pretty sure Verizon SIM cards are only for their devices. I don't think they work otherwise

I've read from a few different reliable sources, don't have any links on hand. But its the phone that is locked to a carrier, not the sim that is locked to the phone, so as long as the device is unlocked and has the required hardware, it should work with that sim.
In verizons case, at the very least the LTE should work with an LTE device, I'm not sure about voice, 3G, and 2G.
In that case you wouldn't get 3G on other phones, since the SIM cards Verizon has are for 4G LTE only, their 3G networks are CDMA and thus built into the phone.
LTE is a GSM technology which is the only reason they use SIM cards at all

That is what I was thinking, but the data card seems to have both CDMA and GSM bands and when I pop out the LTE sim from my phone I lose all signal not just LTE.
Now what I'm thinking is that, since the SIM holds all the Account info, etc, not just 4G related things, that if I pop it into the 3G data card, (I've seen Iphone 5 SIM be put into a 4s and work) that it should work. That is if the Data card is compatible, which I'm not 100% sure on.
The SIM in a GSM phone holds all the account information. The SIM in a CDMA phone is for data only - the phone will work for voice/text without it. The SIMs are different software/wise.

That's what I initially thought but, If that's true than why is my iPhone 5 not able to use Data, voice, or text without the SIM inserted?
I'm not to worried about it not working, the thing I'm concerned about is verizon messing up my plans if I try using the sim in a data card.
Do I have to have a Verizon sim card to turn on advanced calling option? I can't get voice and data while on call. I'm using att sim

Try changing the network mode from global mode to LTE / GSM / UMTS. It worked for me and I'm using T-Mobile. If you are trying to do video calling I still havent figured that out yet. But at least you can have data while your on a call.
Advanced calling is only available on Verizon's network with a Verizon sim card.
I don't know if there is another way to enable simultaneous voice and data on a Verizon phone that is on another carrier, but I know Advanced Calling won't work.
Also for Verizon advanced calling only works when you have LTE connection.

i wonder if there is a way to access the service menu to change the bands. this phone has more bands then what it is using right now. the marshmallow update made it a little better. i have 3g while calling. kinda slow though. i can tell you guys that there are absolutely no developers tinkering with the verizon version of the note 5 and s6 edge plus. i mean nobody. all the devs have left the scene. we are on our own for now until someone steps up. its true rather you want to believe it or not. this is the end for samsung phones on verizon.
I have Galaxy S7 (SM-930FD) dual sim variant. I'm currently using Sim 1 for Data and Sim 2 for Voice Calls/SMS.
The Mobile Operator for Sim 1 only has 3G coverage in our place, and i'm currently using a 3G Plan on it.
I wanted to know , should i keep Sim 1 on LTE/3G/2G mode or 3G/2G mode(since there is no LTE as of now).
Will it make any difference in Data transmission speeds and Battery backup (in choosing between either of the 2 modes) ?

Hi
I do not think it will be such a huge impact on battery life but to some extend it may , if you "ask" your phone to "listen" to what signal are out there he will do it , the more signal you choose the more wakelocks (kernel) it will have , been LTE the highest priority it will always try to find that signal even if it is connected to 3G and no LTE available.
Data speed would depends on whatever your carrier has
I would keep it 3G/2G mode
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.
I verified a very wierd behavior. Even if I selected the 4G on both Sim, the sim not selected for data traffic is always forced to connect to 3G 900MHz. If I go in areas without that kind of coverage that sim becomes unreachable. I can deduct that dual 4G is actually a fake , isn't it?
