Bring your own 4g Router for Smart Hub service?

Has anyone had success bringing a third-party 4g router to their rural Smart Hub service?

I just tried to set up a Netgear LAX-20 4g router and was told by tech support that no BYODs are allowed at all. The Netgear should work (proper LTE bands), and in fact I managed to access a "device not compatible" Telus web page, which suggests that it does connect. But the phone rep said they could not activate/permit the device at all. 

But that's the thing with Telus support: ask 5 guys, get 5 answers, and always with the impression that they're just reading scripts without really knowing anything. 

Curious if anyone has had any luck with this.
