The supermarket giant and Optus have released new pre-paid mobile plans on the Optus 4G network with increased data and unlimited talk and text.

The new offerings follow on from recent efforts by both Boost Mobile and amaysim to lure customers with new 28-day plans and much bigger data allowances.

The supermarket giant says its new recharge options have been designed to help phone users manage their mobile spend and budgets with greater choice and data inclusions.

The two new pre-paid plans include a $20 recharge with unlimited standard national talk and text, and 2GB of data and a $40 recharge which offers 7GB of data, unlimited standard national talk and text, and 250 international calling minutes to China, Hong Kong, Japan, Malaysia, New Zealand, UK, US, Singapore, and South Korea to use within Australia within 28 days.

In addition, Coles has kept its "$10 for 10 days" recharge option, which was also recently boosted with 600MB more data than was previously offered. The offer now includes 1GB of data, plus unlimited standard national talk and text to use in Australia within 10 days.

According to Tim Cowan, head of Mobile Marketing at Optus, pre-paid customers want greater certainty about how much data they get with every recharge.

“With more data, more recharge options and the Optus 4G network getting stronger and reaching more Aussies, in more places, we’re confident we have everything here to deliver the great value and mobile experience that prepaid customers are looking for.”

Coles general manager non-food, Andrew Mossop, says the company has released the new pre-paid mobile recharge options offering unlimited standard talk and text, and “generous data inclusions” demanded by its customers.

The new recharge options on the Optus 4G network (in selected areas and on compatible devices), are available at Coles supermarkets and Coles Express.
