This is a tough one. I have spoke to almost everyone I know and still did not come right. I am using Forums as a last resort now.
I have a BB 8900 and the only problem I have is the messenger. My e-mail and internet and everything else works fine. Here is what happens;
If I add someone or if someone adds me via PIN then on both sides it says waiting for authorisation and nothing else happens or can be done. If I add someone via e-mail address then all is ok. We can have each other in the messenger list. now here is the problem. Everyone can send me messages and I get them but for the life of me when I type back the other person does not get a single message.
What setting could be out / wrong.
ps: I had the 8310 which did the same thing - I now did a device switch and I think the "setting" followed with.
Hope I gave enough info.
what I have tried:
1) putting my sim card in another phone and someone elses card in my phone.... same problem so can't be the sim card
