"Residual bandwidth" in our markets.  Haha.

Interestingly our bandwidth caps have created this sense of "I bought it so I'm going to use it".  So yesterday for instance my 3G HSPA+ service from CellC - advertised performance 21Mb - was delivering throughput of about 100Kb at best.  That's because everyone was trying to "use up" their remaining cap.  Conveniently for CellC it would be impossible to use much bandwidth at such a low speed.  Of course its rare to see more than 2Mb even at better times.
