The iNSight Charging Gateway (iCG) is very similar to the iPG, providing a highly secure and scalable interconnected payment gateway connecting payment systems with service providers. In this case, however, it manages users subscribed via a Wireless Application Service Provider (WASP).
It also offers an additional Customer Care interface that offers the network operator visibility and control over a WASPs current subscription and charging models, which improves customer support.
