Apple brings carrier billing to Italy, Austria & Singapore, but still no US availability

The option is limited to a single carrier in each country — Three in Italy, Drei (Three) in Austria, and M1 Limited in Singapore. It's not clear when or even if other local carriers will be supported.

Beginning with a single provider, though, follows Apple's pattern in other markets. Carrier billing is now available in a total of 12 countries, the others being Belgium, Germany, Japan, Norway, Russia, Saudi Arabia, Switzerland, Taiwan, and the United Arab Emirates.

The U.S., Canada, and the U.K. are among notable gaps, presumably because there's less need or demand for carrier billing.

Carrier support can be important in regions where credit cards are rare or unpopular. In Germany, for instance, many retail transactions are still done with cash.

That country was the first to adopt carrier billing for Apple services, starting in Oct. 2015. Russia came onboard two months later, but for much of 2016 those remained the only two markets with support.

Further expansion began last August, initially through Taiwan and Switzerland.
