This is interesting. India the primary way for in app purchase is via the provider. Credit card penetration is low.
- It must be an international credit card - It must never have 3d-secure enabled
International Credit Cards are costlier, and it just takes one payment on an Indian gateway to enable 3dsecure accidentally. And then, you can't use your card again on any international purchase because no international gateway supports 3dsecure.
