The OVO SIM cards will be available in selected outlets from this week onwards, and follows a deal to offer the cards in 617 7-Eleven stores last week.

"It's been another big month for OVO. The bricks-and-mortar retail strategy is really starting to build momentum as we cater to people who either prefer to purchase items like mobile and data plans from a shop, or want the added convenience of not waiting for their SIM to be posted to them," OVO chief executive Matt Jones (right, below) said.

"Our combined presence across Australia Post and 7-Eleven stores gives us true national point-of-sale coverage. We're expecting this to drive further growth in subscribers, particularly in the lead-up to Christmas and as families prepare for back-to-school come January."

This includes OVO Mobile − Mini, known as OVO's kid's plan as it was designed specifically for parents who want a plan for their tween and teenage children. It offers 1GB data, $200 calling minutes, unlimited SMS and a free family zone cyber safety account for $9.95/30 days.

Australia Post will also sell SIM cards pre-loaded with the OVO Mobile − Large plan, offering 8GB data, unlimited calls and SMS and 300 international minutes to 32 most dialled countries for $34.95/30 days.

"Due to these two plans, the bulk of OVO's customers are families; parents are buying plans for themselves and their school-aged kids. The accessibility of Australia Post for families was one of the key reasons we were so keen to have OVO available in Post Offices, giving us a national footprint that extends heavily into regional Australia," Jones said.

"As an Optus reseller, OVO has been able to take advantage of Optus's $2 billion-plus investment into strengthening its network in regional and rural Australia. Having a presence in a national retailer that includes these centres gives us more opportunity to service these customers.

"I'm confident we'll see a real increase in take-up of these plans through our partnership with Australia Post. Both plans are exceptional value and, particularly in the case of the OVO Mini plan, offer something that's not available anywhere else.

"One of the reasons OVO is growing so rapidly is the escalating reluctance of Australians to commit to long-term contracts. We're attracting customers who can no longer justify paying a premium for no discernible benefit, especially now when they can walk into a convenience store or post office, port their existing number over to a better-value pre-paid service and be up and running in hours.

"We're expanding our retail footprint so as to better reach these customers who maybe don't realise they have a better choice available."
