Now Windows Phone users who are SingTel mobile postpaid subscribers can now bill your purchases via the store to your SingTel account. With this simple & convenient payment option in place, SingTel subscribers do not need a credit card to pay for apps and content on Windows Phone Store. They can also enjoy the one-stop convenience of having all of their app purchases consolidated into a single easy-to-manage bill.
In August 2013, SingTel was the first carrier in Southeast Asia to allow their subscribers to charge their purchases on Google Play directly to SingTel account.

*Update: StarHub will be providing directly billing service for Google Play and Windows Phone Store from Q2 2014.
