OPTUS has stepped up its battle against Telstra by offering customers a new range of plans which allow them to take their mobile data across multiple devices, including tablets - on the one bill.
Under the plan, you can share you mobile plan's data with up to five mobile devices with no ongoing fees.
Optus says it is also offering no lock-in contracts for customers bringing their own phone.
The telco says the plans will offer more included voice and date.
And to prevent 'bill shock', customers can pay $10 more for an extra 1GB of data a month.
Optus Australian chief Paul O'Sullivan said the plans built on the breakthrough My Plan products launched last year.
"Once again, we're delivering on our commitment to provide industry-leading products that dramatically change how customers use data.
"These are our bestplans yet. We're confident our customers will love them and these plans will convince moreconsumers to join Optus."
As part of the device sharing plan, there is a fee to set up each device.
"There's no ongoing cost, just a one-off $5 set-up fee per device. This means no more chasing Wi-Fi hotspots or using battery-draining tethering,'' Mr O'Sullivan said in a statement.
"Customers told us they loved the original My Plan products, and thanks to their feedback, we're making these plans even better.
The new My Plan delivers all the benefits of our previous products with more included voice and data plus the added value of data sharing.''
No lock-in contracts
"Increasingly, customers don't want to be locked into a contract, and are happy with their existing phone. Optus is the first major telco to deliver a great value SIM-only plan, with the added value ofdata sharing," Mr O'Sullivan said.
