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.)
But surely in those cases the JIDs would be something like:
[EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] rather than using resources to denote them. Richard
