Ok
An SMS message = 160 characters. Thats 1280 bytes, slightly over 1KB. An ethernet packet has a data capacity of 1500bytes, more than enough to carry a message. I have a router here at work which - just checking - TODAY - transmitted 2,334,987,122 packets. The router cost £600. Ignoring line costs for now, For my £600, I could have sent over 2 billion texts at a cost of approx 3x10^-5 pence each. Now, assuming that router lasted one year, and my figures above are based one half days sending, thats about 6x10^-8 pence per text, or 0.0000000535p/sms

Now thats just me. Maybe there's a giant infrastructure to support the transmission of all these texts. But I tell you what, there fucking isnt.

The biggest cost to the telco for SMS services? The billing. The billing of the SMS is the biggest cost, not the infrastructure itself. If they stopped billing you for sending texts, they'd probably save money.
