I have a 8520 from TMN (Portuguese carrier) and i'm trying to add a cousin of mine who has a 8900 in the USA. Don't know what carrier.
The thing is, i add him, he doesn't get my request, he did the same thing, adding my PIN and i didn't get his request, it just shows as pending confirmation and nothing happens.
I'd just keep on doing it the way you guys are doing it until it eventually adds
eachother. This is something that happens sometimes. Just gotta keep trying.
If you don't have Blackberry Internet Service (or maybe BES/BESX if you are a business man) your 8520 won't access the servers and the requests will never reach destination, ora pois.
Does your cousin have any other contacts on his BBM? It may be that his BES administrator has disabled BBM however if he has other contacts that won't be the case.
