Which 4G router to choose for 2 SIM cards?

Question

WiFi

Good afternoon!
Now I want to use a 2-SIM LTE as a root router for high reliability, there are options for industrial routers positron, robustel, irz and even such a little-known atm (manufacturer yeacomm), but all of them are not cheap (from 20 thousand rubles). I don’t want to use it with usb modems, I want a solution out of the box, but now it turns out that there is no cheap one on the market.
Which solution to choose in accordance with price / quality, but not with industrial reliability!?!

Answer 1

Mikrotik is out of fashion these days?

Answer 2

Answer 3

Also interested in this question.
Is there still something cheap out there?
For example, MTS for 250 rubles per month and another operator for the same price.
That is 500 rubles a month.
And equipment at least up to 10 tr.
