solution to low bandwidth - convert data into voice or sms?

[shwick]

I was browsing through the canadian smartphone plans and noticed that data was very expensive.

I also noticed that minutes and sms were much cheaper and were sometimes unlimitied.

Is there an app or service that takes advantage of this?

I'm talking about converting internet data into voice or sms, sending it through the greedy phone network and parsing it at a receiver which then forwards the request on to its destination.
