Correct, but bear in mind that your device is constantly sending and receiving data, so even if you're not actively using BBM, e-mail, or the web, you are incurring charges. You can disable data services, but then your BBM won't work. Even if you disable it, then only enable it to use BBM, your device will send you all of the data was queued whilst it was powered off, resulting in no real savings.
