Joined the forum looking for some help on using the new Vodafone 3G modems, and in particular the Vodafone (Opticon) K3760 but seems that none of the current Vodafone models work with Draytek routers, probably as they need switching from memory to serial device mode before they can be used as a modem.

I've had success with the Vodafone e172 on a contract sim.
