When I try to send a approval message to another blackberry so that we can use messenger, they never recieve my message and if they send me one I never recieve their message. What do we have to do in order for it to work?
I usually add them to my address book first then from BB messenger send an invite. Don't know if this helps. Does BB messenger need a data plan? Don't know. Hopefully you can get this issue resolved. I don't know what I'd do without my contacts to help keep me occupied during those boring days at work.
