Nope -- BIS is carrier-specific. Note how each carrier has its own BIS site, for example...

That's it. You only need to mess with HRT if the service books aren't automatically pushed to your BB. Normally, this isn't an issue. Nothing's stored on the SIM card. The SIM just ties your device to your wireless account.

It will work but you'll need to set up BIS with the new carrier. BIS won't "follow" you from carrier to carrier like BES does. See my reply to amit2001...
