SkynetGlobal offers suck-it-and-see WiFi

"Because WiFi is a new technology, people want to try it out without being tied to a contract or commitment," said SkyNet CEO Jonathon Soon. Soon said SkyNet has signed 400 users as part of test marketing campaign.

"People like it because it is a one-off cost," he said.

The prepaid options range between $49 and $149, with per minute charges ranging between 12 and 16 cents per minute. The credit can also be used for international roaming, although the rate jumps to 50 cents per minute.

Credit is valid for 12 months. Cards will be available from Qantas Club lounges and Rydges hotels. Users will also be able to dial up and purchase credit with a credit card.

Soon said usage is already split 50-50 between prepaid and contract subscribers.

Soon would not be drawn on SkyNetGlobal's total number of subscribers, saying only that it is "more than 3000".

He also declined to comment on SkyNetGlobal's cash position, which has been called into question by the ASX in recent months.
