If you look at most nz isps they have plans that throttle your speed down to 64kbps if you go over your cap. why don't any isps offer a different throttle speed of 128kbps instead of 64kbps?
Some isps like vodafone and xtra have different data caps but they have the same 64kbps throttle speed. with the recession and things getting more expensive i would think people probably can't afford to purchase a higher data cap plan so i am just wondering why isps don't differentiate their throttle speeds to attract or keep customers?
for example xtra and vodafone have the same 64kbps throttle speed and their caps are nearly the same. if xtra kept it's 64kbps throttle speed and vodafone increased their throttle speed to 128kbps then i would join vodafone.
so back to my original question. why don't nz isps have different throttling speeds?
