About a month ago, I cancelled my Blackberry Data Plan for economic reasons. Short story.....All my BlackBerry Apps became worthless....since they consume Data. So I hid them, till I reactivate my Data Plan one day. However, I was wondering if my Instant Messaging app (AIM) also consumes Data? or is it like SMS? Another question, if I don't have a Data Plan, however I have unlimited messaging, can I still send MMS, or Video Clips from a my phone to another phone? or is that still consuming Data?
