Imagine you owned a telecoms company who is a major player in the UK and other countries.

Would you not make your pricing as simple as possible?

Surely yes…

In this case not.

BT use a very complicated way of calculating your bill.

Have a look here if you don’t believe me.

Here is an example of the calculations – I will go into more details at a later date.

Calls under 1 minute: Call = < 1 = time (in mins) * ppm – if less than cap price use calculation otherwise use cap.
Calls greater than 1 but less than 60 minutes: Call =< 60 = time (in mins) * ppm – unless capped then use cap if less than 60.
Calls greater than 60 minutes: Call > 60 = time (in mins) * ppm.
