It depends on which SMS gateway is provided by your mobile operator and 
and who operates the number you're trying to reach. And yes, it's mostly 
about money and other limits that mobile operators have in their gateways.
(So for example, if my phone is operated by operator A, and I'm trying 
to send to a number operated by the same operator, I probably want to 
use operator A's gateway. But if the number I am trying to reach is from 
operator B, operator A's gateway may not allow me to send this message 
for free. Also using operator B's gateway may be not-free for me (as my 
number is operated by A). But maybe it will be cheaper with my current 
cost plan. Etc, etc.)
