freitasm: Seriously folks, this is stupidity... At 140 bytes per message (not 160 as standard SMS), and $0.20 each, it comes to $1497.97 per megabyte.

Go get a smartphone and forget about this.

I guess you don't send text messages at all anymore?  That's a silly analysis.  It's not really based on a per byte thing is it?  Probably most texts don't even fill the capacity.  A 3 byte "yes" means the cost balloons out to nearly $70k per MB.  Oh noes!  Better make sure if you do have enough money to burn to send a text that you at least fill up to the 160 character limit, it's better value!
