Vietnamese mobile operator Mobifone and mobile payments company Fortumo have launched carrier billing on Google Play, according to a press release.

More than 25 million Mobifone subscribers can now purchase apps and in-app content from the app store and charge the payment to their phone bill.

Mobifone is the third Vietnamese mobile operator to launch Google Play in Vietnam with Fortumo as its integration partner. Fortumo also has relationships with Viettel and Vietnamobile.

"Vietnam is one of the leading countries by economic growth in Asia today, which means a huge number of people coming online and consuming content on their smartphones," Gerri Kodres, chief business officer at Fortumo, said in statement. "We are excited to partner with Mobifone in helping them partake in this growth and delivering to them the Google Play billing solution in such a short timeframe."
