Openwrt 3G router settings

[dervissh]

Hi folks, I have a little TPlink 703 with Openwrt running on it. I wanted to connect my usb stick from Vodacom (k3765) to create a WIFI hotspot so my pc and tablet can connect through it. I travel to SA a lot and this setup would be very helpful

I have being searching for the APN/PIN/etc setting and cant seem to get the USB to connect though the router. Is there a guide or setting list anywhere?

Thanks!!
