Looks like it.
Will confirm tonight. It wasn't too hard either, just a few lines in the terminal via SSH. I got it setup while sitting in my car
Update: Looks like the B315, being a consumer-grade CPE, does not support VPN with the Huawei firmware. I am not sure whether you can get custom firmware loaded for it, but I rate your best bet will be either a PC at home with VPN software running on it or a dedicated router that can handle VPN. I also checked and my public IP definitely changes when I am on the VPN, so the internet is routing correctly through my Telkom B315 @home
If I were you:
Source a good second hand or new Raspberry Pi 2/3 with an 8GB MicroSD card, load Raspbian on it, configure it with SSH (optional), VNC (also optional if you find cmd-based SSH too tricky) and OpenVPN via PiVPN.
