Carrier billing allows phone users to buy apps without having a credit card, and therefore expands the market for app buyers significantly.
Telekom Austria Group’s domestic subsidiary A1 has today announced that they will be making carrier billing available to Windows Phone 7 users.
The work has been done as an alliance with Nokia and Microsoft, and A1 is offering the first 1,000 customers to buy a Nokia Lumia smartphone (Lumia 610, 710, 800 and 900) a EUR 10 voucher for the Windows Phone Marketplace as a credit on their phone bill.
