Hi,My 8830 used to work peferct on BIS some 6months back,but it has stopped when I activate(subscribe to BIS).I've tried wiping the device,reistalling the OS and I called my service provider to send me service books but I don't receive them and I don't get the response if I send a HRT registation message.How can I solve this problem?Thanks
Most carriers allow the ability for you to resend the service books from their website. Look for the smartphone functions on the carrier website to are if yours has that function.
