Optus 'yes' Plans for iPhone 3G

Alternatively, post-paid customers can choose from non-Cap "Yes" plans that include similar amounts of data each month, lower month spending allowances, but cheaper fees per minute once spending allowances have been reached for the month. For instance, the $19 monthly plan still includes 100MB of data, but only $14 worth of calls and texts. Additional calls cost 46 cents per 30 seconds and the Flagfall fee is only 25 cents per call. Text messages remain 25 cents a piece. Under this plan, a 12-month commitment allows customers to pay off the 8GB iPhone for $49 per month and the 16GB iPhone for month $59. The 8GB iPhone costs $19 per month and the 16GB costs $17 per month with a 24-month commitment.

"Yes" plans scale up to $149 for a package that includes 1GB of data and $144 worth of calls and texts.

Yes plans, however, do not appear to include Voicemail as standard. "Yes" plan subscribers get to choose one of four calling offers: "Yes Time, MyTime (Free 5 minute voice calls to 5 family members or friends), Yes Free Text (100 free text msgs each month), or Yes Text & Talk (22 cents talk or text on any mobile, any time).
