My mums just got a new BB 7290, she can make calls to any mobile number when finding the number in the address book, but when she calls a landline it says the number like this +44(then the number) then it wont ring and it says congestion. but if she dials the number then presses to make the call its just fine. Its only when she presses the number from the address book it wont call.
Whats wrong with it?
