Call incoming calls are "Unknown Caller"

I have Blackberry Bold 9900 with T-Mobile.  All incoming callers are unknown callers.  I have updated and updated but still showing unknown caller.  


It just suddenly stop.  I was told by Tmobile it maybe the installation of Viber.  Is this true?  If it is, is there anything I can do to fix the problem?

Re: Call incoming calls are "Unknown Caller"

Hi Tinapay21,


Welcome to the BlackBerry Support Community.
Have you already tried uninstalling any recently installed 3rd party applications to see if that fixes the issue for you?

If that doesn't help, do your outgoing calls display the name of the contact you are calling? Do you have content protection enabled? Here is how to check: "How to change the setting for Content Protection on the BlackBerry smartphone" http://blackberry.com/btsc/KB11963


I look forward to your response.
