Google has made good on its promise to expand carrier billing for the Android Market internationally today, introducing the feature to customers on various carriers in three countries. This is great news for consumers, and even better news for developers.

South Korean users on SK Telecom and KT Corporation, UK users on Vodafone UK, and German users on Vodafone DE will all be receiving access to direct carrier billing in the coming weeks.

Carrier billing is a major feature for users in countries outside the US, where Google Checkout support for regional banks and credit cards can often be severely wanting. There's also the fact that most people outside the US have never even heard of, or don't trust, Google Checkout.

Google has promised even more news about carrier billing in the coming weeks.
