SMS is sent as a "Short Message Service" text, using your text plan.

iMessage is sent as data (140 characters = 140 bytes) using your data plan.

Let's say you're paying $10/month for 1000 texts.
1000 texts is a *maximum* of 140,000 characters.
Including some overhead, let's say 150,000 bytes, or 0.15 Megabytes.
At $15 for 200 megabytes of *data*, that costs well under $0.02 for 1000 iMessages.
