Vodafone's UK and German operations have made it possible for customers to pay for Android apps using their mobile phone account, rather than having to use Google's systems.
The move was announced on Friday, with Vodafone saying it marked the first deployment of operator billing for Android Market apps in Europe.
"Vodafone UK and Vodafone Germany will help consumers purchase their favourite apps and games on Android Market even more easily without the need to enter credit card details," Vodafone said. "This will give developers direct access to millions of Android users who can now charge their Android Market purchases straight to their phone bills or prepay accounts."
The first customers to be able to use the new payment mechanism will be those who bought their phones directly from Vodafone.
The operator said many potential app customers were unwilling or unable to use credit cards to buy mobile applications, with more than 90 percent of some markets falling into this category.
