I searched on this site and read that BB Messenger uses data (not SMS) to relay messages. That's fine with me, as I have an unlimited data plan. But what about sending a BB message from one carrier to another (i.e AT&T to T-Mobile)? I called AT&T's support and could never get a definitive answer. The first rep said no charge, but after checking said that going from one carrier to another incurs standard SMS charges. He said he'd check further and then changed back to his original answer: BB Messenger between carriers is free.

I just want an authoritative answer. Anyone know for sure?

As long a you both have data plans you can have free BlackBerry messenger.

BlackBerry Pin Messenger is the BEST free IM application that one can get...

Free across ALL carriers; like Adlen said, as long as you have a data plan...

How big is the Messenger file size ( typical)
Now if we have limited data plan like our friends up north ( Canada)?

BBM to BBM is Free no matter where in world you are

[Optimus_Prime]

BBM to BBM is Free no matter where in world you are

only if you have data plan, correct?
if you don't have data plan, when the BBM will not work, correct?

You need a data plan and a BIS account (commonly reffered to as a BlackBerry plan) to allow access to your data plan. If you have a data plan but no BlackBerry plan you are paying for internet you cannot use.
