Woolworths has announced the launch of a new mobile phone company in Australia, Everyday Mobile.

Offering prepaid services and using Optus' existing mobile network in Australia, Woolworths Everyday Mobile SIM cards will be sold for $2 at Woolworths, Safeway, BIG W and Dick Smith retail stores.

The Everyday Mobile service aims to simplify prepaid mobile services, by offering a flat rate of 15 cents per 30 seconds for voice calls with a 15 cent flagfall. Text messages will cost 15 cents and MMS messages 50 cents.

Customers can recharge their prepaid Everyday Mobile service online, over the phone or in selected Woolworths outlets including Caltex Woolworths fuel stations and Dan Murphy's stores. Everyday Mobile users will have up to 100 days to use any purchased prepaid credit.
