Vodafone is to charge its pre-pay customers $1 each time they seek help from its call centre staff.
The company wants to reduce the number of pre-pay calls that are made to contact centres, and the charge comes into effect on 1 August.
Vodafone spokesperson Alison Sykora says the move it to encourage people to change their behaviour, rather than to save money.
She says customers can look up the company's website. or seek help via their mobile phone.
Ms Sykora says the company is investing $30 million into expanding its self-service options, and says most Vodafone customers prefer the online tools.
