Had said this before; we need to investigate how we can chart handshake messages versus actual internet payload.
I had made the argument that Safaricom charges for all data between the phone and the core network - get, push, pull, put etc

However, somebody on the list made an argument that the handshake/control data is very minimal; whilst somebody in the industry had made an argument that this 'control data' could account for over 50% of the actual data.

If we could find a way to quantify the amount of 'handshake/control' data to Safcom Core then we could have a case.

A long time ago, 100 bob used to last me a week on phone browsing; siku hizi barely 2 days - something is definately up!
