Omni antenna does not give good improvement compared to directional.
Best to save your money and get the MIMO.

Most people see good improvement.
Possible to get this speed if you are close to the base station with 4G only
Even if it says 2CA, still need to see what bands it supports.
Phones like One Plus 3 says 2CA, but the China sets don't support Malaysian 4G+

It depends whether a telco enable it actually.

I know currently Celcom, Maxis and Digi all have B3+B7 CA.

It could be they are upgrading their network. Maybe you can try and ask their CS.

I found a firmware on a Russian forum with VoLTE enabled. PM me if you are interested to try.

Only for the brave ones. 

I can't try as E5186 is my primary internet connection currently.

What version of webui you want and what features you need on them?

Must be place dependent.. My place not even a LTE-A covered area but still can capture the signal n force it to lock to 4G+
In my case I'm using Samsung phone tethered to tp-link router.. At perfect place and angle I am able to capture both B3 and B7 to use lte-a.. E5186 is a powerful CPE and I believe it has more capability than my Samsung phone.. Just need to find the sweet spot for it

Finally get to enjoy LTE advanced with my netgear AC 790S
Love the netgear app support for sure. Pretty handy
Able to enjoy it without battery is really a plus , unlike huawei mifi for sure.

Speed is really huge difference for user come from 4g LTE . needless to say is minimum double that LTE device like Huawei B310S-22, huawei E8278s-602, redmi 4x, and so on.

Worth ever penny

LTE or LTE-A?.. single band 7 
netgear mifi also got better signal reception compare to huawei
but negear mifi kenot send sms
