Why is it that - SMS

Why is it that in times where gigabyte devices and high speed mobile networks are becoming more and more mainstream, we cannot send more than 150 characters in an SMS without getting billed extra ?

(Wikipedia to the rescue)

It seems that technically, there is a limit of 140 bytes in the messaging protocol used between the SMSC and mobile device. However, that protocol also defines that larger messages can be segmented and that it’s up to the receiving device to reassemble the messages.

Operators however insist to bill each segment separately. Why ?

My guess is that they are still trying to compensate for their temporary loss of any common sense during the auctioning of the 3G network licenses :-P
