Shane:

Thanks for the feedback. Do you happen to know where to find more information on these aggregators? Much appreciated.

You'll need to forge agreements either with each carrier or go through an aggregator. Each carrier deals with billing differently. Some place the MSISDN in the HTTP header so that you know the ID of the user for billing purposes (this is generally frowned upon but done), others may use a sign on token for verification. In some cases, you may have to query back into the carrier systems to verify that the user has an active PDP context. The list is endless and specific to the carrier.

And the way these agreements typically work is that the carrier will bill the customer and then settle with the vendor at the end of the month.

One simple example is that if I come up with all kinds of cool ring tones or wallpaper for cell phone, and like to sell it 5 cents a piece via Android, I really don't want to use credit card for payment, and I only needs to know the phone number of the buyer. It is preferred to charge against user's cell phone account at its carrier, and I will settle my account with the carrier directly at the end of the month.

Any comment?
