Only when it's simple.  When a country is small or is big but has a 
single state telco incumbent and a few mobile carriers, that's not too 
hard.

Of course you can get blended domestic US48 termination - most people 
do.  But, two things happen when you hit a large traffic volume that 
cause that to go away:

1) *You* lose on the blended rate for high-density and/or highly 
competitive destinations you could route to for rates under the blended 
plan.

2) Your providers get increasingly nervous about their exposure to your 
all-over-the-map traffic patterns, ability to adhere to a theoretical 
80% RBOC blend, or whatever.  So, high amounts of traffic start to get 
broken apart into much, much more granular (and therefore numerous) 
tiers, sometimes down to the terminating carrier.
