I am facing an issue with my Blackberry 8330 mobile phone early everything was working fine. But today i am not able to send and receive calls. Whenever i am trying to make an attempt any calls I got an message as Call Failure and my phone gets stop working when it's entered into dialing mode. But when i am able to send and receive all text messages. Can anyone tell me what would be the issue in this case.

I would suggest you to first have a soft reboot by pressing ALT+rt SHIFT+DEL key. Once soft reboot is done you phone will get reboot. If you still facing the issue then try to remove the battery for 1 - 2 mins and place it again hope this works for you.

I was also facing similar type of issue whenever i receive a call it used to get calling out. so i removed the battery and upgraded my software to 4.5 version because older version is facing similar type of issue when i went to service center they told me that majority of the people are coming up with this problem.
