Call is generated in this visled country, where the home of the SIM chip operator wil pay $2.50 The network where the call is made, gets to retain $.34.
This operator, where the call is actually made, pays $2.16 to the carrier next in line to handle the call.
Operator A transits the call. Receives the call from network where call originates from. Operator A collects from originalng network operators $2.16, and will keep $.25.
Operator A sends the call to Operator B and pays the receiving operator $1.91.
Operator B transits the call. Receives the call from Operator A Operator B collects $1.91 from Operator A and will keep $.20.
Operator B sends the call to Operator C and pays Operator C $1.71.

Operator C sends the call to an enlty "owning the Premium Number Range". Operator C pays the PNRO pass thorugh $1.46.
The Premium Number owner passes through the revenue to the Internalonal Revenue Share Number provider which is usually (not always) the same enlty as the content porovider. The revenue of $1.46 being passed through to the IRSN If the final network which owns or leases the Premium number from an Number range owner, does not own the content, they will keep example of $1.00 and pay to content holder $.46.
The Internalonal Revenue Share Number Network will terminate the call to the premium number called.
