I can pay apps in the OVI Store on my N9 only via the operators phone bill.
Now I have a business SIM owned and payed by my employer, but the phone is mine. I should not buy apps and let my employer pay for it. There is no option to use a credit card.
I read somewhere else (cant remember where) that some operators have such policies. There was also the advice to remove the SIM. But this did not work on my N9.

Any way to get around this and pay with a credit card?
