On 1 July 2007, Crazy John's made the transition towards becoming a Mobile Virtual Network Operator through the Vodafone network. The deal allowed Crazy John's to deal directly with mobile phone handset manufacturers and offer its own competitive mobile phone plans. Just days before the switch to Vodafone, Telstra sought a court injunction to prevent Crazy John's from using confidential information in contacting Telstra's customers to sign them up to new contracts. Crazy John's agreed to limit the amount of customer information it can use after its contract ended.
