New mobile virtual network operator (MVNO) Callplus has come out with a range of plans targeting mainly prepay customers with low rates for calls and text messages. Callplus general manager Mark Callander says the consumer offerings will be done under the Slingshot brand, with two plans available later this week. The first, Mobile 1, will have a contract length of six months and cost $10 a month. For that, customers get three-tiered pricing for calls that Callander says is designed to encourage people to use their mobile more. The first minute is charged at 50 cents, with the second minute costing 40 cents, and any subsequent minutes charged at 30 cents. This, Callander says, makes it simple for customer to understand how much they spend. Unlike existing prepay offerings, customers are not being penalised by high calling rates in the 89 cents a region, Callander says. Mobile 2 is the second Slingshot plan, with a one-year contract at $20 a month. For this, customers get a flat 25 cents per minute rate to any mobile network in New Zealand. Text messaging packages for the two plans cost $9.95 for 2000 messages, or $6.95 for 600, again to any New Zealand network, Callander says. The first minute is fully charged and from then charged per second, he says. Read more at Computerworld.
