The company introduced a WAP portal in 2004, but take-up was slow.

"The WAP service had problems around speed and usability. We decided to go down the track of the Java application simply because it is much more useful and a lot cleaner," he says. "Customers only have to log their phone in once and then it is recognized and they can go straight to information search."

Terralink is still testing the Java application among a group of customers.

"The response so far has been ecstatic," says Grainger. "The application won't work on BlackBerries at the moment, but apart from that there are no problems."

When the service goes live in a couple of months, customers will be able to download the application (45KB) into their phones when logging on to Terralink's website.
