Suddenly cannot place or receive calls

I have a Blackberry Curve 9330, with Verizon as a carrier.  For the last couple of days, I have not been able to place any calls.  When I attempt to do so, either the call does not complete, (call was lost), or if it does go through, I get a very rapid busy signal.  I have checked the carrier reception and it is strong.  I have checked the WiFi...it is receiving a strong signal.  I have spent hours trying to figure this out and have finally given up.  I have taken the battery and sim card out twice, also, hoping to repair whatever it is that has gone wrong. Can anyone give me some ideas?  Thanks

Re: Suddenly cannot place or receive calls


I recommend that you attempt to boot into Safe Mode:

  • KB17877 How to start a BlackBerry smartphone in Safe Mode

It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, then see what happens. If the behavior stops, then think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.


If the behavior continues in Safe Mode, then you likely should seek formal support from VZW.


PS -- on VZW (indeed, all CDMA carriers), the SIM is not relevant...you can operate your BB just fine on VZW with the SIM not even installed at all. Perhaps you should try that as well...

Good luck and let us know!
