I recently came across this post by Paylater on their Facebook page: https://www.facebook.com/paylater/posts/1591963947555617
To summarize, MTN internet subscribers and internet users can make use of the app without it affecting their data balance.
I'm curious about how this feature was implemented. How exactly does the app determine which connection you're using to browse?
How does MTN identify internet traffic coming from a specific app and know not to deduct data charges for that app as opposed to all other internet traffic coming from other apps on a mobile device?
I'd appreciate it if any of the gurus here can provide me with some insight on this.
