I have been looking through the Spark web site and I cannot find the 3G/4G USB modem any more. On trademe there are a couple of listings of Telecom T stick which are obviously quite old given they are labelled Telecom rather than Spark. Do they still work?

What I am trying to do is to have prepay mobile broadband while staying at a beach house we have access to. As we do not go there often enough we cannot justify paying for regular broadband, and we thought prepay mobile broadband on a USB modem so it can be shared via a wifi router would be the way to go.

Vodafone reception is poor there so Spark is really the only option.
