Hello, thanks for the heads-up. Check www.mymusic.com.ng, they don’t use shortcode billing. Once you hit the download button, your airtime is deducted without any need to sign up. I researched and found out it’s a facilitated by a technology called :
The HTTP Header Enrichment (HHE) capability provides solutions for a content provider to identify a subscriber.
Basic HHE allows the subscriber to be identified by their MSISDN.
I would like to know, is this what the aforementioned Aggregators use to facilitate payment?

Thank you
