Europe has always been relatively friendly to Windows Phone, such that the OS sells within only a few percentage points of the iPhone. In some regions, particularly Eastern Europe, the OS actually does a lot better, routinely selling better that the iPhone.
One such country is the Czech Republic , and there O2 has just added Direct Carrier Billing to the payment options users are presented with when buying apps and music on their Windows Phones.
Sebastian Böhm, Senior Vice President and Executive Director responsible for Payment Solutions at net mobile AG, who provided the solution for O2, said: “The fact that Windows Phone has a strong foothold in the Czech Republic is one more good reason to offer Direct Carrier Billing as the most popular payment method among O2 customers in Windows Phone Store.”
Microsoft currently offers carrier billing on more than 80 carriers worldwide covering a potential 2.5 billion customers and notes that the availability of this feature increases total paid transactions by 8x per month in emerging markets and 3x in developed markets.
The Store also supports a very wide variety of other payment sources including PayPal, Alipay and even Bitcoin.Source
