I have implemented subscriptions in the application with the Google Play Billing API . Testing successfully used a credit card.
I have problems with purchases made using direct faxes.
Here is what I have (testing only on American media):
- AT & T - works great
- Verizon - Works great.
- Sprint - getting the error that "Direct Ticket Payment is not available (IAI).
- T-mobile - Works great from 5/21/13.
Interestingly, trying to buy regular applications using Carrier Billing seems to work, the problem is only in buying subpages in the application .
Eliminate all configuration problems, etc., since an error occurs in the Google Wallet GUI (after clicking the "Accept" button), and it works 100% of the time for AT & T.
Does anyone know what happens with DCB and IAB to subscribe to T-mobile and Sprint?
Update 04.20.2014 . It seems that the problem was on the operatorβs side. IAB v3 seems to work too. Your mileage may vary with other carriers.
Update 05 27 2014 . It also looks like Google has added US Cellular to the list and works well with IAB V3.
